Antoine Walter: Hi, Denise. Welcome to the show.
Denise Mall: Hi, Antoine
Antoine Walter: Iβm very glad to have you. Weβve been discussing that for a while now. We will be touching on a very fascinating subject in just a minute, but right before we start, can you send me a postcard can you just tell me where you are and what I should know about the place where you are?
Denise Mall: Okay. So technically IΒ am in the center of South Africa, based in Bloemfontein right now, which is in the free state.Β Β
Iβve landed there because my mom got ill and she was visiting my brother and he lived in Bloemfontein so we decided to come over.
Iβm quite mobile and can travel. Iβd love to be doing international travel rather, but itβs proving to be quite interesting actually.
Becoming a Water Professional
Antoine Walter: Β we are going to be talking about water today quite a lot. And Iβd like to understand how you got first interested in that field of water. What brought you to that?
Denise Mall: I think we have to kind of start with, how I ended up in engineering. I think thatβs really where it starts because itβs not really something most people end up in and being in the industry for 35 years now. , that means I went into the industry way back in the mid-eighties. So yeah, I landed in engineering by mistake.Β
So what happened was I was in high school, final year and the company approached the school for a drafting position. They were looking for a young girl to train in drafting. And I think like figuring out if I wanted to be an architect and maybe even like, thought about the reality that.
Engineering as a Woman is still a long shot
Drafting isnβt just architecture. So no Google, no background research.Β So the sad part of that story is that in high school, we were never, thinking to work in engineering. Cause like you had to become a teacher, a doctor, lawyer.Β I literally stumbled into it. but They offered me the job and thatβs my baptism, into engineering. I started drafting water in thatβd be water resources, amazing stuff.
And within six months offered to boost me to go and study, and that was my journey into engineering.
So long story short.Β I think we are all connected to water subconsciously or consciously.Β It is part of what we are.Β Looking back through my career now, I donβt know how it was ever going to be anything else, you know, but it has evolved.Β I was apparently the first woman in the company to ever be boosted for engineering.

I mean, it didnβt really hit my radar, but this was like exceptionally abnormal. And I couldnβt figure out why they made me jump through all these hoops two days or second metric testing. Lots of questions about what is my long-term plan. What happens if I become a mother and Iβm not even thinking about that, I just want the job.
And I just want to study and this looks really interesting.
Biomimicry as a Career Turning Point
Antoine Walter: You just cracked a major spoiler about the next step of our discussions. But right before jumping, into this way that nature can, itself solve the water issue and how nature can treat water.
What I would be interested to understand in your path is how you switch from being on the traditional side of the water sector β this engineering path and all these elements β to a non-governmental organization with EnsO Earth today. So how does that happen?
Denise Mall: Iβve always followed my gut instinct and thatβs the things you do, I think it was my destiny to be working here. And thereβve been a lot of small incremental steps that kind of bring you to where you are.
And then when you look back through your life that you join all the dots, you know, the pivotal point came in about, 2008. Iβve moved to the Western Cape from Johannesburg.
Meeting the Grandmother of Biomimicry
And I was trying to. Figure out life. I was on the path of trying to understand sustainability and the Cambridge Institute or sustainability actually brought up Janine Benyus to Cape town, to present live.
And if anybody in this industry understands biomimicry sheβs like the grandmother of biomimicry, she coined the phrase, she defined the principles, to be able to see Janine Benyus live was an opportunity that far exceeded my comprehension back then, because she was relatively newΒ I remember walking out of that presentation.

How did we get this so wrong? It was mind-blowing when you finally realize that all the answers are there, we already know what we need to know. We just need to unlock it. That was the pivotal point because he was coming out of that presentation that I pivoted my company from doing industrial and mining projects.
Pivoting a company to have an Impact
Thatβs was that 2010 and starting off pivot towards green, a project, looking at green alternative energy projects are being like a wind farm. And then itβs no plant and OPG plants. And then about 2012, I heard about this thing called social entrepreneurship and Iβm going, oh, that sounds interesting.
So basically that is how can you do good and make money? Well, I could do that. Really the focus thing was how do I promote biomimicry within South Africa?
Itβs evolved into creating the biomimicry, foundation in 2018 with some fellow colleagues. And then also realizing that there was a whole lot more to this than just biomimicry.
Beyond the concept of Biomimicry
I was battling to make that hard connection between biomimicry and infrastructure design because nobody has joined these dots. So if Iβm starting and teaching or promoting biomimicry, but still not being able to connect it back to the engineering industry, which is where I really felt it needed to happen,
And It became more about why I originally wanted to start the foundation, which was all about how do I ensure that my great-grandchildren will have a planet. But it kind of goes back to the original 2009 meeting where I found Janine Benyus. The fact that we could go beyond sustainable to regenerative design.

It is about Saving Ourselves!
And the reason we want to do that is that we need to ensure our longevity as humanity on this planet. And thatβs, I think thatβs when the penny first dropped, but if we donβt fix it, there isnβt a future generation.
We find ourselves when we find ourselves and when things present. You have the choice to grab onto it or just ignore it. And this was a situation. I found myself at a position in my career where I didnβt like what I was doing to the planet.
I realized, the impact of those actions. And I was really basically finding the last sentence or the death sentence of my future offspring, if Iβve been, do something to change it. And thatβs what the formation or the foundation is.
What is Biomimicry?
Antoine Walter: Before zeroing down, on the net positive water, youβve used a lot, the term biomimicry, which weβve heard already on that microphone a bit when I was discussing with Michael Stanley Gallisdorfer, but letβs define it,Β for everyone to grasp what the concept is, what would be your take at the definition of biomimicry?
Denise Mall: Basically nature has spent 3.8 billion years doing the R&D that is required to produce life. All we have to do is learn from nature. So we spend all of our energy teaching people about nature instead of learning from nature.
The three levels of Biomimicry
And then the next level is what does nature teach us? And there are basically three levels that we can learn from these. Imitate natureβs forms. So thatβs your shape and your, your structural spider of nature. Well, we can learn her recipes, which are your processes. So this is the chemistry of nature we can monitor systems.
Which is really the systems within the system or the processes within the systems, but the most powerful design of a one incorporates all three levels. So where you design in the context of Biomimicry, you looking at natureβs foods, you look at natureβs recipes, youβre looking at natureβs systems and youβre weeding that into the solution.

Thatβs in a nutshell is biomimicry. And basically, itβs a perfect gateway into this realm of regenerative design or systems thinking and design thinking
Leveraging Ecological Design Thinking
Antoine Walter: I love that concept. Actually. It is your tagline on a website, this ecological design thinking. just incredible. If I get it right, when you do this empathy, the first phase of design thinking, usually you go to your users and you watch them evolve and you look at what they do, and you try to understand the challenge and then come with solutions.
And if I get you right here, itβs you go to nature and you try to get from nature. Whatβs happening right there. And what can we replicate? Is that a right encapsulation of your concept of this ecological design thinking?
Denise Mall: Thatβs exactly it. So what, what do you do when youβre looking at applying biomimicry is basically you look at the boob and you go, what are we trying to do? So in other words, weβre trying to purify water. What would nature do to purify water? And, and the biomimicry Institute has got this amazing stack called ask nature.
But you basically just type in what youβre trying to achieve and they catalog all the potential solutions that relate to what youβre trying to do. Thatβs really been hard because of all the donkey work, you know, and the leg work to create the system and the platform that helps us design, in alignment with what nature would do.
Biomimicry, Circular & Donut Economyβ¦
Living future, biomimicry, circular economy, Donut economy, they are all fundamentally the same because itβs all been based fundamentally on nature.
So nature solutions and the realization that nature designs, cyclicly or circularly. So thereβs, the start thereβs a boost. Thereβs a growth, thereβs a maturation, thereβs aging, and then thereβs a dying. And then thereβs a reboot that is the design of nature and the byproducts are always the starting point for new life. And that is also the essence of circularity and circular economy.

Antoine Walter: When it comes to water and wastewater treatment or remediation, whatever we call it,Β is it a silver bullet? Can you take like designed by nature? Copy what nature would do and can we really solve for everything that we are putting into this water? Because some of it is, of course, I mean, thereβs nothing on this earth, which has no link at all with water, but some of the components weβre putting in there are really so heavily transformed that they are barely still natural.
Is Biomimicry a Silver Bullet?
So biomimicry as itself. Can it solve for every kind of pollution weβre putting into the water?
Denise Mall: Letβs just backtrack a bit here quickly. I want to define the water cycle. Okay. Because we both know that water is a finite resource. Itβs just because nature does the process or the system, so well, that it creates this. The illusion of infinity, but the reality is that thereβs no more water today on the planet than there was 4 billion years ago in various forms, like evaporation, whatever it is itβs a finite resource.
Itβs the illusion of infinity that nature creates, fundamentally, we all drinking recycled, dinosaur pee.
Antoine Walter: I love that one.
Denise Mall: No way around it. Knock you back when you frame it in that context. When you think that all the water, we consume all the water that comes through the system, fundamentally is the same water that was on the planet 4 billion years ago, 3.8 billion years ago, the same water that the dinosaurs drank and peed.
Understanding the Water Cycleβ¦
Itβs the same water. Itβs nature. that heβs doing what it does really, really well to create that illusion of infinity. Just the same water going through the system time and time again. So what we need to be doing is replicating that.
And the problem with what weβre doing in the modern systems is that weβre giving nature fundamentally, stuff that it doesnβt recognize and identifies. So the minute we put chemicals into the system, that nature does not respond to or know what to do with it fundamentally becomes waste. And our problem isnβt so much how well is this?
How do we proceed? Okay. Itβs the fact that weβre not processing the way nature can handle it. So, so when you break it down, when you realize that. Most of the pollution is us giving nature chemistry. She doesnβt, identify and therefore doesnβt know what to do with, or are we giving it to her in volumes or quantities that she cannot manage or break down in the process or the timeframe that she requires to do the process?
β¦ to stop sabotaging it!
Okay. Or weβre working against the natural processes and sabotaging her ingenious designs of purifying air and water by putting stuff into the system that disrupts it. So like for example, deforestation in favor of monoculture agriculture. That disrupts the purification of the air pushing whatβs there, but back into the atmosphere, creating rates.
And itβs when you start to truly understand the natural cycles that you can start to identify on the system, the systems design, or the regenerative thinking where you can start to identify where the intersection points need to be to fix the system.

Basically, when you look at the planet in the context of a planet, itβs one very funny chain ecosystem that operates as a whole, I think shows our ability as human beings to live on it.
When we start to disrupt it, we create pollution, we create waste, we create contamination. We create all of our products, which are complete by-products of manβs inability fundamentally to design in accordance with nature
We are the problem we have to solve
Antoine Walter: so what you say is that if we rush forward, because, at one end of the cycle, we are disrupting something that means that at the other end of the cycle, we have to solve for that something and by being more intensive, heavier on the treatments and, and if you keep pushing on both ends. Well, itβs never-ending at some point. Itβs going to be so heavily disrupted.
Denise Mall: Thatβs exactly whatβs happened. That is, that is our climate reality. We have pushed all the natural boundaries to the point of breaking, you know, and, most of us, I think, I donβt think we intentionally set out to do that Antoine. I think we did it as ignorance. You know, we thought we are clever.
But we werenβt that clever. you know, and weβre now realizing, that the answer is actually quite simple, we just have to go back to how nature does it, and then boom. Into what weβre doing now.
Biomimicry is all around us
The irony is that weβve been doing this intuitively for the poor while already without realizing it, you know, like I said to you earlier on and leading to this robotic defined mimicry, we were mimicking the way the body naturally lives, know, internet of things. Its feedback loops in, in systems itβs leveraging the technology to create, digital twins at some level are trying to mimic, and control nature.
Even blockchain is at some base level biomimicry, Thereβs so much technology thatβs coming forward that has not evolved out of people going to look at nature for the solutions. And thatβs, whatβs actually aiding us to, start correcting the problems.

And one of them in the chemical and water and wastewater treatment is the realization that they donβt need chemicals.
Biomimicry applied: The Living Machine Project
Antoine Walter: Letβs take an example of that. Can you guide us through your living machine project so that we see how that works when itβs applied in the real world?
Denise Mall: The living machine was really just one small element or that same net positive water. Cause it really just feels this wastewater treatment. So the living machine is using nature to purify water wastewater.
Youβve got your anaerobic, your aerobic, and then like your filtration and polishing, and those happen at different stages in the system stuff. In the end, the aerobic level, youβve got the biodigester and yes, biomimicry again the biodigester mimics the stomach and the way we digest our food.
And really the byproduct of that is the methane gas, which is then harvested for the cooking. But this again is also a great area within the different categories or peak peopleβs framing of the context. Cause in living future, weβre not allowed to use gas in any form for cooking. Okay. And then weβve got your aerobic process, which is the classic cells.
And these are already a series of separate cells. I see different things, you know, one is for aeration. The other ones are for filtration and, and youβll actually see the water quality improving as you take samples from those to settle.
Biomimicry continues outside of the building!
And then we basically go into the constructed wetlands, which is really where the filtration and polishes happen on that large surface areas. Where a lot of the microbial activity takes place.
The bacterial, and this is the reality is that there are always microbes and organisms that naturally feed on the, like in the anaerobic processes, a whole lot of microorganisms that literally feed on, I think itβs nitrates and the phosphates and stuff like that to create what it needs to do for the next stage.

At the end of it, you end up with really purified water to the quality that can be naturally discharged into a river course or watercourse, according to the regulations and the bylaws and the requirements from the government on water quality. So all you can literally direct it into hydroponic, farming, aquaponics, conventional farming.
There is no βWasteβ in Nature!
So thatβs the reality of that. But in principle, itβs really taking the natural life cycle of water from where it lands get contaminates. And this is what fuels the disconnect. We think weβre the only people contaminating you know look around. There are lots of animals living there. and they are all pooing and weeing and we donβt smell like HESTA Ridge farm. Do we? And Iβm like, yeah we donβt.
Β Nature just does what it does and nobody thinks about it, you know, but we, we actually messed it up when we put water with the mix, you understand?
So when you actually get into the way nature manages waste, it actually does separate the liquids and the solids, even in our own body, the design is separating liquids from solids, but we waste and did as engineers. Weβll just throw the whole lot together and add waterΒ we actually created a problem
This is aΒ colorful conversation!
Biomimicry Level 2: Net Positive Water
Antoine Walter: Β Iβm pretty sure nature doesnβt call it a waste. Itβs just a part of the cycle. And we humans call it a waste. And if you call it a waste and you have to treat it as a waste and you have to just sort it out, but if you donβt consider it a waste and if you say itβs a resource, like another,Β is that what leads you to this concept of net positive water?
Denise Mall: Thatβs exactly it. Thatβs exactly what it is Antoine., It is the realization that waste does not exist in nature. There is nothing called waste in nature, everything is a valuable building block, a natural resource. that is part of I think, net positive water. Itβs not the whole of net positive water cause wastewater treatment, only a sector because what net positive water is trying to do is mimic the natural water cycle.
Net Positive Water: A concept all along the Water Cycle
It starts with rainwater harvesting, it looks at the water management, it looks at wastewater management, and then it looks at it from an integration of the whole, how do they cross over and how do they influence each other?
Because how we design is that when you go to cancel for submission, you will do your, um, growth and wastewater submission together. And then youβll do sewage and water submission together. But the truth is that the two systems influence each other because when youβre looking at.
How your rainwater harvesting, diminishes your stormwater flow and redirects it into another system and then takes your wastewater and reclaims it to reduce your water demand. Thatβs what we call the ecological water balance. When you look at it within the context of the whole thatβs net positive water, because now youβre having to manage the entire cycle, of water from rain, water, or potable water, wastewater, stormwater within the context of the site.

The first fundamental is always in the context of place. Because your soil type, your topography, your climate, all of these things will influence whatβs your final net positive water balance look like.Β You want to be able to keep this close to what the preconditions were to happen, the environmental impact.
Letβs define Net Positive Water
Antoine Walter: Thatβs the part which I donβt get because to me, the natural water cycle is fully neutral. You have water, as you said, which is still the same. Then we had millions of years ago and what the dinosaurs had and everything. So, That to me is all neutral. So how do you make it positive?
Denise Mall: Β How they define it in the industry, okay. Is basically net-zero is the equal sign. So your water consumed is equal to your water reclaimed. Which is 50%. . With the net. Positive is the greater than, and others, your water recycled is greater than the water consumed.
So anything greater than 50% is considered positive. And how itβs defined is, for example, when you look at your water balance, your personal water consumption is only 30% and your wastewater reclamation is 60 or 70%. Then in principle, youβve got net positive according to the definition, but youβre absolutely correct that because itβs a finite element or resource, technically you can never get positive because you can never create water.
The water cycle, from a net positive water standpoint
You can never reduce water. Itβs really how they define the positive is a boss, how much heβs reclaimed and what percentage of what is going in is actually reclaimed recycled. reused et cetera, et cetera.
Like I can do an entire podcast on literally net, positive water design because itβs fascinating because that was the pivotal point in my career.

And it only happened like a few years ago when I realized thereβs actually a different way to do this because we have been. So indoctrinated and taught to follow the design codes and never question letβs see, talk with, when you start to break it down and I donβt know if itβs different in Europe, but the stuff we can, Africa care, we basically get a hundred percent of our water from the municipality or the city.
What is Drinking Water all used for?
We pay for that. The reality is that only 30 to 40% Β true potable demand.Β That is really for drinking and ablutions. Showering hand-washing is true. Potable source. Cooking, true potable source, but as a part of it, almost like 40, 50, 60%, or itβs non-potable use depending on obviously what youβre designing the building for.
So those, those numbers will vary. Okay. But when you come down to think that we basically spent all this money to buy potable water to literally in one toilet, flush send it down the toilet and contaminate it instantly. And then we have to pay, a municipality to retreat that sewage and send it back to us as potable water.
So we can repeat the cycle and thatβs insanity because we havenβt realized itβ¦ I like the way youβre laughing because when you realize that, you realize that thatβs net positive water because thatβs the insanity of it and people donβt even realize weβre doing these double-dipping costs because weβre not looking at water fit for purpose. Why do we need potable water to flush a toilet?
Have we really thought through our Water Uses?
Antoine Walter: Well I guess it comes back to what you said at the beginning. Itβs we had the engineering in technical capability to do so. So we did so, donβt think it was thought through. I donβt think that someone ever, I hope so at least that no one ever came up and said, Hey, I need drinking water to flush my toilet.
Itβs just, I mean, that was the water available, so letβs use it. But if you think of it as a system, itβs different.

Denise Mall: When you go back into like the engineering behind it. you realize that the reason they did it is so they didnβt want a double plumbing system.Β We didnβt have the technology. 200 years ago when the Victoria came up with this ingenious, idea of flushing toilets.
The reality is that water was abundant. We didnβt have the population growth we do. It was really available. You could harvest water source, just flush it down, you know, and it went away, but nobody thought about the impact because we hadnβt been so involved enough in our thinking to realize that impact or what we are creating.
And thatβs something I donβt think we intentionally set out to make a mess. We just happened to make a mess. Now that we know weβve made a mess, can we actually ignore it? Do we not have an obligation to fix it?
Can the International Space Stationβs Water Management serve as an example?
And I think thatβs really what it comes down to. And thatβs why I started a nonprofit is because thatβs also, I had an obligation as part of the problem to actually be part of the solution. We now have the technology. And if you think of it laterally, I always refer to the international space station.
20, 50 years ago. We figured out how to put a man up in space. At least for periods of time. Theyβre not water tanks. , itβs a closed-loop design. And thatβs when the penny dropped for me. When I realized like, this is how we could design a booming, we donβt need infrastructure. network, actually, it becomes redundant.
Itβs now all about making that affordable for everybody.Β
Antoine Walter: Exactly, because the international space station can afford to run on a 98% recycled rate because thereβs just no other solution. It costs so much to send a 100-liter cube of water to space. So itβs just not a question you recycle, but as long as itβs still and Iβm using a lot of brackets here, easy to access to water and earth, itβs going to be difficult to make the economical point of closing the loop and of reusing more, which leads me to, to my question actually, fully get your explanation around why it makes a lot of sense and why itβs stupid too, to deal with water the way we do, but what is the trigger we need for everyone to realize that.
What would it take?
We are going into the wall. If we keep doing it that way, how can we grasp water scarcity?
Denise Mall: I think we do need to grasp, but I think, you know, when, when you start looking at the global projections of when weβre going to run up water, you know, we, we alluded to the discussion about day zero in Cape Town, but you know, itβs going to be day zero for many countries. It already is, you know, weβve got to be a draught in the California region, you know, thereβs the erose, thatβs run dry and, and itβs only because we havenβt managed it properly.

Do you understand? Thatβs the economics. I think Antoine is when is the financial equation or the business case for the international space station, the criteria that make it important for us to achieve it. In other words, when does water becomes so expensive that the international space station solutions are actually cheap and affordable.
Thatβs going to be the tipping point or the tipping point is when do we make the international space station solutions so affordable that everybody can do it. And that is what drives the technology. You understand?Β That is also why we need, non-profits almost to be pushing the boundaries because this is where the innovation leads from. Because while nobodyβs challenging the possibility or looking for a solution because it takes a lot of energy and money to prove the case study, to develop the theory, et cetera, both the business cases to get it to that point where it really adoption happens.
Water Scarcity as a Tipping Point towards Net Positive Water, Biomimicry, Regenerative Solutionsβ¦
And then it becomes the norm. The more water-stressed we become. The bigger, the need will be to solve this problem.Β In South Africa itβs becoming a reality because our situation is that 90% of our wastewater treatment plants arenβt functioning, theyβd be neglected. Maintenance has been done.
So the traditional system has failed. Weβre dumping roasters until water watercourses and you think we havenβt got a problem and the people are still not proactive in doing this. And thatβs the simple solution. We have a split by treatment system distributed through nature problem-solve but because itβs so foreign in our way of designing,Β instead of looking laterally, I think that there is an alternative solution that is actually all more energy efficient. It just does its own thing. It doesnβt even need managing.
We are just busy with a case study. Now, the business case of how you scale it up because. We, as engineers are very conservative, we donβt like risk. We chasing our tails. You know, weβre not looking for real solutions.
Weβre looking at how do we avoid the problem,Β
How to break the Water Silo?
Antoine Walter: the other element which I see in, what you just said is that when you talk about the living building or the living community, itβs also breaking the silo. Because if you look at only water before it gets economical to recycle everything, itβs not a matter of your great children.
Itβs going to be a matter of. Thousands of generations. But if you look at the broader picture, and as you explained your anaerobic step, youβre producing some methane you can be reusing that methane. And maybe there is some phosphorus, which is still in the water at the outlet.
And if you do, aquaponics or hydroponics, you can use that phosphorus to just water your crops. Then your crops are going to deliver you a better yield. And that is just, I mean, an oversimplification of the stuff, there are just so many streams, but that goes with a circularity that goes with interconnection.
The road to micro-utilities, decentralized and distributed solutions
And that goes a lot with distributed solutions and decentralized systems, which are just living in their own community, wherever they are. And once you reach that point, then the economical tipping point is much closer because actually you just have to kickstart it, but then the full circular flywheel is starting to roll and to work.
But that is counter-intuitive as engineering because youβre, as you just explained it, when youβre an engineer, especially water engineer, you know, the, that the water industry, you have no clue about the engineering sector. You have no clue about the agriculture sector. And so you think just inside your silo.

So itβs about, enlarging the picture and having a look at the whole system, which is probably the scale of where non-profits have a good position and where government shall kick in because they are supposed to be the ones that can break those silos.
What if we teamed up?
Denise Mall: Thatβs exactly it. Antoine. And thatβs why we doing it because we realized that to build the capacity, we need to shift the industry into this line of thinking. You have to create a space that will nurture that level of thinking. And it is about a multidisciplinary team. So when I talk net-positive water, okay.
You actually have to be a civil engineer. You have to be a mechanical engineer. And, Β§ou have to be a process engineer. You have to be an ecological engineer and then throw them in there. You probably have to be a landscape architect or landscape, some kind of personal growth plants, and understand plants and which plants are best suited for what.
The philosophy of living building is harder. We designed a building to operate as a flower. They harvest energy, harvest, sun water, it grows their own food. It does all of the things that it looks pretty and itβs explicit.
Biomimicry (again) and Biophily
But letβs put itβs real stuff. You know, itβs the biophilic thought of is what makes our environment, , conducive to us being happy and functioning and thriving. So those are the philosophies of design. And this is what really frustrates me with this is that the architects love it. Okay.
And then youβve got the engine and they just donβt show up, you know, The one thing, this is relative and yet it is so relative because itβs part of that. So when I, okay, let me say to you the positive sides of make positive water. If you can imagine a building, okay. And thatβs not harvesting, itβs on water.

Itβs retreating its wastewater. Itβs using that nutrient-rich wastewater and booted commerce to grow. Its own food, itβs pushing back operation back into the atmosphere. Itβs recreating its own rate. Itβs functioning within the footprint as a complete closed-loop design.Β Is that not the best situation?
When you see the benefit over, instead of sending that wastewater to havenβt gone down the road or the hillside for somebody else to make a problem with it, we need to know how to harvest that and use it as a resource.
Nature works in a closed loop, so shall we!
When you realize that by closing the loop on the wastewater system. You contain all the contamination.Β All those pharmaceutical by-products, those drugs, those hormone tablets, and all of that stuff. I think that ending up in our watercourses.Β Itβs just this closed-loop design that allows the building to retain its contamination footprint. You get plants that will extract all of that stuff. We actually seriously delve into that. So the nature side of it, and what plants can do for us: itβs mind-blowing!Β It can reduce radioactivity in soil. I mean, thatβs not the first time I heard about that.
I was like, damn, who should be gone to kids every week?

Antoine Walter: Okay.
Denise Mall: I was like, but thatβs the reality of it. Our plants that take up heavy metals, actually fix the problem for us without asking anything, but we would rather go with an engineered solution that takes a lot of energy, a lot of money to fix the problem that weβve created.
That nature could probably resolve for us with energy and effort.
How to break the patterns, in a specialized society?
Antoine Walter: If I want now, to be the devilβs advocate for just a minute. What youβre describing goes really against the way our societies are built.
Because we always go down that path of ultra specialization, even to the points that today. Someone that would be a water engineer, wouldnβt define himself as a water engineer he would say, Hey, Iβm specialized in a certain type of disinfection in the drinking waterside.
And if you come with something about wastewater heβs going to be a bit. Yeah. You know, I donβt know about it because Iβm not specialized in to that. And now youβre saying that we should be at the same time doing a bit of landscaping, a few architectural works a bit of this, a bit of that. So that taps into the other side of the coin, which is now centralized system are maybe inefficient are, maybe not the best solution, but at least you have the scale effect to have all the specialists needed at those places.
And I tell you, it goes against my own conviction. So Iβm really playing here, the devilβs advocate role, but, I tried in my own garden too, to do a bit of aquaponics. And all I ended up with is that my fish were starving and the crops never had any yield.
It was just terrible. At some point, you might come to the limits of the way we are designed as a society to deal with circularity. How do you overcome that?
Did you guess it? Biomimicry, again π
Denise Mall: What youβre saying, Antoine is correct at some level, but thatβs because our society has driven us into that direction. We used to be generalists, then we never used to be specialists. But thatβs not how our society developed where you got pushed into having PhDs to be able to analyze this.
And that makes a lot of sense.Β Unfortunately, itβs going to be the specialist. Theyβre going to drive certain frontiers if that makes sense.Β The secret to this isnβt individual, . Itβs community. Okay. So if was in your community, you have people, you can specialize it as a whole, you function as a unit.
So now if you put the analogy back, say your body. With lots of individual little cells in the body. Okay. But then a lot of little cells have a common function and they become the liver. And then another little bit of those types of compunction and they have, become the heart.
But as a whole, they all have an important role to play in the body. And thatβs, I think what we have to think is that if we have this seeing ourselves as little individual cells, but potentially as an organ within the biggest body, And thatβs systems design again.
But as a whole, within the footprint of our community, all our needs are being met. When we start to see off the teeth through that kind of link thing, it becomes. Infinite. Whatβs the potential is to change how we live and operate in cities.
Whatβs the role of EnsO Earth in this transformation?
Antoine Walter: What is your role as EnsO Earth into this transformation almost you wish to see.
Denise Mall: So weβve understood why I created the non-profit, you know it was about the longevity or be managed on this planet. For a more personal reason, Iβd like to be able to know that my great-grandchildren can actually have a planet to live on
But my role is how do we ensure that future? The focal point was going back to what are the basic essential needs for life, which were clean air, water, and food. And this is how we ended up back at water because the water drafts at all, you know, the waters needed to create the food with creates vegetation that creates the P E.

So just in that little loop, that is fundamentally what we focused on. So weβve identified that water is. A pathway to us obtaining our goal. And itβs a critical pathway because what people donβt understand is that you canβt have one or the other, you have to have clean air youβve got to have clean water and youβve got to have food to live.Β
If you donβt have any one of those three, youβre fundamentally dead. And then thereβs a scale to that. You need eight minutes away, you need three days of water and you need 40 days of food. And when you start to understand those numbers, then you understand how critical that balance actually is.
Ambitious and Innovative Projectsβ¦
So what is our role as EnsO Earth? How do we look at that little cycle of the penny will tend to be and ensure that because we donβt pollute our water sources, how do we reduce our water usage in agriculture and farming? How do you upcycle wastewater to be a substitute for, Iβd say, raw water in the agricultural process, and then understanding that all of that vegetation is actually part of the carbon sink footprint?
Itβs what drives the team. Itβs what drives the water vapor into the atmosphere. And itβs actually quite interesting when you started to make that connection and that you realize that itβs actually not the lack of water, itβs breaking that cycle.
So some of the water became obsolete, not obsolete, like diminished, which drove the vegetation to not grow, which drove the cycle to not create water there. So that thing grew up, drove the cycles, and did not produce rain. when you realize that, then you start to understand a lot of these revegetation programs that are happening globally, and how the entire thesis has been brought back to life.
β¦ that start the ball rolling!
But what we focus on is four key areas, to the nonprofit. Itβs the advocating. How do we reach people and teach people what the cycle needs to look at? And then they thought, Iβd say our education and training is how do we create printers who can train in positive water?
How do we help them develop the skillsets to be able to become the next generation of regenerative designers? And then basically they train on real projects that can create that impact. Weβre not training on fictitious stuff. And the design is one of those things. Itβs hands-on. You have to do real design work to actually translate the theory.
The critical link to all of that is the funding because nonprofits will unlock funding to do the projects, to create the training, to be able to shift the outcome.
How to measure success when youβre an advocate of Ecological Design Thinking, Biomimicry and Regenerative Solutions?
Antoine Walter: How do you measure your success and what will make you look back in five years or in 10 years and say weβve achieved something which was even better than what we expected.
Denise Mall: Β Each one of those, has its own metric or KPIs.Β Antoine, you know, itβs really coming down to. How much water can we recycle? So I put the advocating, you know, how we look at our analytics, how many people can we reach, you know, education and training. I mean, apprenticeship, uh, printing, have we trained and graduated with more ecological design, you know, um, projects on the projects alone, you know, you, you just looking at how much water reclaimed recycled, you know, and even funding, you know, how much money have we raised to put into projects.
Those are really the metrics that are, we day to be chasing and monitoring,
Raising Funds, Daring, Changing the World
Antoine Walter: for the part of your role, where youβre acting with this, this fundraising. How do people react to your explanations, Iβd call it a narrative. Even donβt get me wrong. Itβs not a story like the ones I attempt to my daughters and that would be a fantasy.
I mean, itβs real life, but, but itβs sometimes a bit disconnected from the perception that people have from the real state of a water infrastructure of our water systems. Oh, how do you,
Denise Mall: Howβd you do
Antoine Walter: yeah.
Denise Mall: take the human element out with them joking. Um, so, so what weβve done, if you can rely on people to donate money, itβs never going to happen. The kid I have relapsed, Iβve been living my own social experience, and theyβll tell you about that offline, but itβs actually shocking how disconnected people are and how apathetic people are at fixing.
or, helping to fix the problem. Thatβs why Iβve adopted this approachΒ
Building the Flywheel
Iβm going to go find my own money and thereβs lots of God funding, and thereβs a lot of money up there actually, but itβs only really available to nonprofits, and then going to create my own projects that can fund from my own money or somebody elseβs money, then convinced them to give to me,
to be able to demonstrate the reality of what is possible. And through that, Iβm just going to train a lot of people to do more of this because Iβm never going to be able to do it on my own.Β And then in the background with educate people about what weβre trying to do, and while weβre trying to do it, but if youβre going to try and advocate them to donate to your cause, youβre your time, youβre never going to get this off the ground. think so now mine time on profit has been self-funded from our project.
So we just got asked to do conventional engineering with a green twist to it, and basically, X amount of our profits go straight into funding the nonprofit, but with COVID we realized the resilience or the lack of sustainability map because if there is no project, there are no these big projects, then all our approval processes stalled in council, because it was just, um, you know, weβve, weβve actually looked at different funding strategies, you know?
Corporate Social Responsibility, ESG, Impact
And well, the grant funding and the corporate social responsibility or the CSI, fundingβs always been me. And, and in South Africa there itβs mostly contextualized. The government has made texting us to tort. So, you know, thatβs a big corporate giving the money. But yeah, I think when you looking at individuals, I mean, there is a funding strategy that leverages car volumes of low numbers to create the kind of turnover you need or the funding to generate.
And thatβs money to do the impact, but if youβve got to rely on that as I said, youβre never going to get them, so we have like multiple pronged approaches with funding, which is obviously self-funding from projects and then looking at government codes and stuff. Then weβve actually just recently in the process of doing an online store to, to leverage, you know, COVID and drop shipping.
And basically, all those products are water or biodegradable nature-based kind of solutions. One is a product thatβs been developed in South Africa is such to figure out how to get to the rest of the world, but itβs an amazing product itβs really linked to the bio-treatment system. And itβs actually green tag, 35.
So all the Greenstar buildings should be using it. And the cleaning process. So really what we did was said, okay, wait, which products weβll forget. Can we link with that? We can sell the products, promote the products to basically generate revenue. We need to cover our operating costs.
Is the βNew Normalβ an Opportunity?
Antoine Walter: I could have an additional 2000 questions, but I try to encapsulate that in the very last one in this deep dive, you mentioned COVID, which has of course worldwide terrible consequences. But if we want now to take like pink glasses to look at, it may also be an opportunity because we disrupted the word one way or the other.
We have the choice between going back to what we always did or saying, maybe thatβs your opportunity to take a fresh start and to look at our infrastructure differently, to look at our investments as communities differently. Do you think that is an opportunity that you may be able to leverage?
Do you see that opportunity at all? Or do you expect it to just come back to a 2019 vibe when all of that is over?
Denise Mall: From a nonprofit perspective Antoine I think thereβs a huge opportunity to leverage it.Β Because what has happened in the corporate world is this whole focus on ESG. You tell me if youβve ever touched on ESG,Β itβs actually very important.
Circularity, Biomimicry, Net Positive Water⦠That shall be the new normal
And what Iβd like to see, thereβs still a disconnect between ESG and actual non-profit benefit.Β But in the same way, we saw the connection with CSR and CSI to nonprofits and being able to donate part of your profit margin to nonprofits. Iβd like to see CSR and ESG get reframed into the global scorecard so in other words, if you, as a corporate or donating to a nonprofit, it should influence your ESG score. If itβs a nonprofit relative to environmental, social, or governance,Β this should be a leveraging on the scorecard,
Thatβs, I think one of the areas where we can tip it, so all the organizations are corporates, RC who manufacturing and doing stuff come to the table. Whatβs the E and the environmental part highlighted.
And they look at the processing facilities, they look up what theyβre doing to the environment. They look at the wastewater reclamation,Β I think there is a point to create the tipping point, and thereβve been a lot of discussions around how we can leverage that, to create that tipping point, because I donβt think the individual person in the street, yes, we can advocate and we can hold, protests and stuff like that.
But the adopters need to be big corporates because thatβs where the tipping point towards that, and the ESG scorecard needs to start reflecting the true impact that these companies are having on a planetary level, not just that an investment value, thatβs what Iβd like to see change. And I think if we can fix that,Β it will report through that, then the non-profits will get the money.
Making the World better, stone by stone
They need to do the work they need to do. There is a tipping point and I donβt personally think we will ever go back to pre-COVID. Itβs changed humanity going forward. It has changed the trajectory of our pot and thereβs a lot of people out there trying to leverage it to the benefit of the whole.
And I do truly hope that that would be our future.
Antoine Walter: Well, itβs a fascinating transition that you offer me here because Iβve been discussing ESG with Florian Heeb and Julian KΓΆlbel on that microphone. And the ESG ratings were something which they really highlighted in their explanations to say that is probably a way to trigger a real impact, at least from the financial perspective, they explained that much better than me. So you can have looked into that interview.
As I said, I could be spending another 2000 questions discussing that matter with you, but if itβs fine with you Denise I propose you switch to the rapid-fire questions.
Rapid fire questions:
Antoine Walter: So in that last section, Iβll give you short questions and you have to give me short answers, but donβt worry. Iβm always the one who is sidetracking the discussion.
Denise Mall: You can cut them off!
So my first question is what is the most exciting project youβve been working on, and why?
Denise Mall: That would be the living building challenge. That was my realization of the 30 years of infrastructure. Best days are a whole different way to do it. Iβd be 180 degrees in the wrong direction. And then I think doing the league was nine to the living community challenge and realizing you can actually scale, make it affordable
Whatβs your favorite part of your current job?
Denise Mall: marketing, telling the story, the why sharing my staff and new ways of designing strategy and packing that pathway, or how do we get there? Thatβs my belt.
Antoine Walter: Well, that is a fascinating answer, I think never, never, never. Since Iβm asking that question and youβre my guests, something like guest number 50, I have never heard marketing coming out so spontaneously. Even when I interviewed BjΓΆrn, he didnβt mention marketing.
Denise Mall: Thatβs my job, as CEO, to tell the vision, the story, the why, I mean, and Iβm passionate about it. I love sharing it.
Antoine Walter: I can experience that right now.
What is the trend to watch out for in the water industry?
Denise Mall: I think itβs an all-around probably the likes of ecological engineering and green infrastructure coming forward, looking for the nature-based solutions. But I think another part of it is also aligning our materials with natureβs chemistry.Β Even in,Β Iβd say, manufacturing, pipework, all of that stuff.
We need to rethink but chemistry weβre putting into the industry. Thatβs our problem.
What is the thing you care about the most when youβre working on a new project and what is the one you care about the least?
Denise Mall: Oh, this is such an easy one. I love conceptual design getting the backbone of the project without understanding that whole system design thing, and then giving it over to the rest of dot the Iβs and cross the Tβs. And my least favorite parts of this job is haggling fees with clients and managing scope creep,
Do you have sources to recommend, to keep up with the water and wastewater market trends?
Denise Mall: I think the CAS in India is doing really amazing work, like leading water-sensitive design and decentralized systems. And, you know, from an African perspective, theyβre very relative because we say that, you know, we face very similar challenges in Africa, economical, but, um, yeah, I think the ones that I would say is done this conference is like the bond Institute, the living future Institute, that they, the guys who were pushing the parameter with regard to, you know, they running the design challenges, theyβre running the product challenges, they, and making us look, they are making us look for alternative solutions.
And, and like I say to you, if you link it to what we need to be doing in the materials, alignment to nature, natureβs chemistry, thatβs the way we have to start, you know, because until we fix that, weβre always going to create waste.
Antoine Walter: And last question.
Would you have someone who would be nearly as passionate as you and that you would recommend me to invite on that microphone?
Denise Mall: So itβs a company with busy doing work with currently evaluating that they are actually a US-based company. But they really doing some interesting stuff itβs called eco solve and they working with magnetic water devices and that impact on agricultural water use. And you know, how are we able to double our yield with half the amount of water due to the magnetization of water?
Antoine Walter: Well, thanks for the advice. And to wrap that up, Denise, itβs been a pleasure. Iβve learned so much discussing with you. And, uh, as I said, itβs a PT that I have to put all of that into an episode. So I would say if you are free, anytime in the future, we can continue on that discussion. I would have so much more questions for you.
Denise Mall: Yeah. Iβd love to see that thatβs to carry on because thereβs so much to know. And I mean, Iβm lost fishless until another ever promotes myself and explains anything. I must generally, Iβm probably an expert generalist if I know a lot about a little bit of everything, but itβs important for what I do, because thatβs how you link the silos is how you break down the silos.
I couldnβt do this job as a specialist.
Antoine Walter: Well, thanks a lot. And as I said, talk to you soon!
