Currently in its 10th Season, the "(don't) Waste Water" podcast has already welcomed around 250 guests from Water Majors (SUEZ, Veolia, Jacobs, Xylem, Kemira, Evoqua, Aquatech, SKion Water...), Scale-Ups (Cambrian Innovation, Epic Cleantec, Gradiant, Liqtech, 374Water, Gingko Bioworks...), Start-Ups (Puraffinity, KETOS, 120Water, ZwitterCo, Membrion, Source...), Universities (Berkeley, the Columbia Water Center), Investment Funds (Sciens Water, Mazarine, Burnt Island Ventures...), Business Accelerators (Imagine H2O, Elemental...), Book Authors (Seth Siegel, David Sedlak, David Lloyd Owen...) or Market Intelligence Companies (BlueTech Research, Global Water Intelligence, World Bank, OECD, Isle Utilities...). Or simply water legends like Gary White, Mina Guli or Andrew Benedek!


On the "(don't) Waste Water" podcast, I strive to make the Water Industry easy to understand for everyone, starting with water professionals, executives, and investors. Hence, he opens the microphone to seasoned, inspirational water experts to discuss their field of excellence.


No one can claim an all-around in-depth understanding of a matter as complex as Water. But piece by piece, you can rebuild the puzzle. With curiosity, patience, and passion, Antoine Walter explores topics such as Advanced Treatment Technologies, Water-Energy Nexus (Hydrogen, Lithium...), PFAS removal, Nature-Based Solutions, Wastewater Reuse, Distributed Water Treatments, Water Finance, and Water Entrepreneurship.


I actually firmly believe that regular listeners of the "(don't) Waste Water" podcast may, in the end, claim a "Water MBA!"


A particular field of interest is how innovation forms, grows and gets widely adopted in a complex and conservative field like the Water Industry. This may be one of the keys to achieving the United Nations Sustainable Development Goal nΒ°6 - #SDG6.


Oh, and in short, about me: I'm a water engineer turned avid student of the water business, market, finance, and tech. I'm married, a happy father of three, and I'm French (nobody's perfect πŸ˜…).

S12E10 - How Crustatec Found Gold in Shrimp Shells - and Used It to Purify Wastewater

Wanna know how the mountains of shrimp shells polluting our landfills could actually clean our water? Listen to this!

In short: CrustaTec is transforming shrimp shell waste into sustainable water treatment solutions. Using chitosan, a polymer extracted from shrimp shells, they've developed both a filter for textile dye removal and a natural flocculant for wastewater treatment that offers an eco-friendly alternative to traditional chemical treatments.

I know the future - so let me share it!

Indeed, yes, I did it again: I drowned myself in 153'482 LinkedIn ads for the keywords "Water" and "Wastewater" from Q2 to Q3 2024 (using a β€œslightly homemade” scraping approach - please forgive me, LinkedIn!).

I did so, looking for the signals companies believe will make them money in 2025 - that's how I know the future.

Why ads, you ask? Well, for a simple reason: businesses rarely burn ad budgets on dead-ends.

So, if they’re paying to talk about it, they must see an ROI!

Here’s the executive summary of what I learned: that's hopefully enough to give you plenty of conversation starters and investment hints!

54:11 Rapid Fire Questions

πŸ”„ Traditional solvent extraction requires 5-7 stages with minutes of residence time per stage - Altillion achieves better results in just 2 stages with seconds of residence time

πŸ§ͺ Recovery efficiency remains consistent regardless of starting concentration - they can extract lithium down to 3-4 ppm whether starting from 20 ppm or 2000 ppm

πŸ’° The focus in lithium extraction is shifting from OpEx to CapEx reduction due to high interest rates and financing challenges

🀝 In nascent industries like lithium extraction, collaboration between "competitors" often creates more value than pure competition

🏭 What looks like a complex water treatment flowsheet is actually a simple mining/oil & gas project by industry standards

πŸ”„ While most companies scale up their pilot plants, Altillion actually built a smaller second pilot unit because their first one was too large for potential partners' testing needs.

πŸ§ͺ Despite being based in Texas with deep oil & gas expertise, they shifted focus away from oilfield brines toward mining brines - not because the technology didn't work, but because it worked too well, extracting even trace amounts of lithium effectively.

I investigate 6 categories and 24 subcategories, identifying top investment areas and key players. I also explore the geographic distribution of investments, the proprietary nature of certain investors, and future projections for Water Tech exits and growth - together with Tom Ferguson (Burnt Island Ventures) and Clayton MacDougald (Emerald Technology Ventures).
