    Why 32 Companies Fight Over 24 Electrochemical Oxidation PFAS Destruction Deals

    How Do 32+ Electrochemical Water Oxidation Technologies Compete for PFAS Destruction Market Share? Listen to this! More #water insights? Connect with me on Linkedin: https://www.linkedin.com/in/antoinewalter1/ ๐Ÿ™Œ Supporters ๐Ÿ™Œ A big thank you to my partner, Georg Fischer: https://www.gfps.com/com/en/products-solutions/solutions/design-prefabrication.html#! How Do 32+ Electrochemical Water Oxidation Technologies Compete for PFAS Destruction Market Share? Electrochemical Water Oxidation is an emerging treatment technology that uses electrical current to break down persistent contaminants like PFAS in industrial wastewater. With 32 identified companies developing proprietary systemsโ€”17 specifically targeting PFAS destructionโ€”this crowded market represents both intense competition and strong validation of a rapidly growing industrial need. Antoine Walter is a water technology analyst and podcast host who has interviewed nine electrochemical oxidation companies, conducted comprehensive market research across 32 players in the space, and provides strategic insights for entrepreneurs, investors, and water industry executives navigating this competitive landscape. ๐ŸŒถ๏ธ KEY SPICES ๐ŸŒถ๏ธ โšก Power Density Range: Technologies span three orders of magnitude (100-10,000+ A/mยฒ), with higher densities potentially enabling more compact treatment systems ๐Ÿ’Ž Electrode Materials: Boron-Doped Diamond (33%) and Titanium suboxide (28%) lead among PFAS-focused companies, with Mixed Metal Oxide dominant overall ๐ŸŽฏ Market Maturity: 53% of PFAS-targeting companies operate at TRL 8 with only two at full commercial deployment (TRL 9) ๐Ÿงช Defluorination Proof: Four companies have achieved third-party verified >90% defluorination, with half reporting complete PFAS destruction capabilities ๐Ÿญ Minimal Chemistry: 58% operate with minimal chemical addition, and 83% self-clean through electrical reversal or direct capacity ๐Ÿฅœ IN A NUTSHELL ๐Ÿฅœ What's the actual market size? Only an estimated 250 of 10 million global industrial facilities have addressed PFAS in wastewater, with perhaps 24 choosing electrochemical oxidationโ€”creating fierce competition for limited installations. How do electrode materials differ? Boron-Doped Diamond offers superior performance but higher costs, while Mixed Metal Oxide and Titanium suboxide provide alternatives, with some companies opting for sacrificial anodes to reduce expenses. What determines system performance? Power density, pH tolerance (46% work at neutral pH), electrode lifetime, and reactor design collectively influence treatment efficiency and operational costs more than any single factor. Are these technologies deployment-ready? Most companies (TRL 7-9) have moved beyond lab-scale, though only Axine and AECOM have reached full commercial deployment with multiple installations. What's the investment opportunity? The collective $120M raised across startups represents capital-efficient validation, with regulatory pressure intensifying and the addressable market potentially growing 10x within three years.

    S13E12 - Can We Actually Afford to Clean Up Forever Chemicals?

    How Can We Afford to Remove PFAS from Our Environment When Treatment Costs Exceed Global GDP? ๐Ÿ™Œ Supporters ๐Ÿ™Œ A big thank you to my partner SimpleLab: https://link.dww.show/simplelab โฌ‡๏ธ IN THIS EPISODE โฌ‡๏ธ PFAS (per- and polyfluoroalkyl substances) are persistent synthetic chemicals used in countless everyday products that contaminate drinking water, wastewater, and the environment. These "forever chemicals" accumulate irreversibly in our bodies and ecosystems, creating mounting health risks for current and future generations while presenting unprecedented economic and regulatory challenges. Dr. Ali Ling is a professor at the University of St. Thomas specializing in PFAS management and wastewater treatment, with a decade of consulting experience helping industrial and municipal facilities address emerging contaminants, and expertise in big-picture systems thinking for environmental risk assessment. ๐ŸŒถ๏ธ KEY SPICES ๐ŸŒถ๏ธ ๐Ÿ’ฐ Cost-Effective Approach - Source reduction is 1,000 times cheaper than environmental cleanup, with upstream industrial controls costing hundreds versus millions of dollars per kilogram of PFAS removed ๐Ÿ”ฌ Technology Expertise - Comprehensive knowledge of GAC, ion exchange, destruction technologies, and emerging treatment solutions across drinking water, wastewater, and industrial applications ๐Ÿ“Š Data-Driven Strategy - Evidence-based analysis showing that removing PFAS at current production rates would exceed global GDP, making source control the only viable path forward ๐ŸŽฏ Risk Prioritization - Understanding that drinking water represents less than 20% of human PFAS exposure, with diet and indoor dust contributing significantly more to health risks ๐ŸŒ Future-Focused Thinking - Emphasis on persistence as a critical factor, recognizing that today's PFAS releases create irreversible accumulation threatening future generations ๐Ÿฅœ IN A NUTSHELL ๐Ÿฅœ Why is cleaning up PFAS from the environment economically impossible? Removing PFAS from the environment at the rate we produce it costs millions of dollars per kilogram and would exceed global GDP, while upstream source control costs only hundreds to thousands of dollars per kilogram. What's the biggest misconception about PFAS treatment? Most people focus on drinking water cleanup as a past problem, but we're still actively producing massive amounts of PFAS today, and drinking water represents less than 20% of human exposure to these persistent chemicals. Should utilities treat PFAS in wastewater effluent? Treating municipal wastewater effluent is extremely expensive and environmentally impactful, whereas addressing industrial discharges and landfill leachate at their concentrated source points is far more cost-effective and logical. How do we prevent regrettable substitution when phasing out PFAS? The European Union is implementing better frameworks that assess both persistence and toxicity before approving chemicals, while companies like IKEA and H&M have successfully phased out PFAS entirely from their supply chains. #๏ธโƒฃ Mentioned Links #๏ธโƒฃ Ali Ling's LinkedIn profile (https://www.linkedin.com/in/lingali/) Ali's paper on the costs to remove PFAS from the environment (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4718530) Hosted by Ausha.

    Why 32 Companies Fight Over 24 Electrochemical Oxidation PFAS Destruction Deals

    How Do 32+ Electrochemical Water Oxidation Technologies Compete for PFAS Destruction Market Share? Listen to this! More #water insights? Connect with me on Linkedin: https://www.linkedin.com/in/antoinewalter1/ ๐Ÿ™Œ Supporters ๐Ÿ™Œ A big thank you to my partner, Georg Fischer: https://www.gfps.com/com/en/products-solutions/solutions/design-prefabrication.html#! How Do 32+ Electrochemical Water Oxidation Technologies Compete for PFAS Destruction Market Share? Electrochemical Water Oxidation is an emerging treatment technology that uses electrical current to break down persistent contaminants like PFAS in industrial wastewater. With 32 identified companies developing proprietary systemsโ€”17 specifically targeting PFAS destructionโ€”this crowded market represents both intense competition and strong validation of a rapidly growing industrial need. Antoine Walter is a water technology analyst and podcast host who has interviewed nine electrochemical oxidation companies, conducted comprehensive market research across 32 players in the space, and provides strategic insights for entrepreneurs, investors, and water industry executives navigating this competitive landscape. ๐ŸŒถ๏ธ KEY SPICES ๐ŸŒถ๏ธ โšก Power Density Range: Technologies span three orders of magnitude (100-10,000+ A/mยฒ), with higher densities potentially enabling more compact treatment systems ๐Ÿ’Ž Electrode Materials: Boron-Doped Diamond (33%) and Titanium suboxide (28%) lead among PFAS-focused companies, with Mixed Metal Oxide dominant overall ๐ŸŽฏ Market Maturity: 53% of PFAS-targeting companies operate at TRL 8 with only two at full commercial deployment (TRL 9) ๐Ÿงช Defluorination Proof: Four companies have achieved third-party verified >90% defluorination, with half reporting complete PFAS destruction capabilities ๐Ÿญ Minimal Chemistry: 58% operate with minimal chemical addition, and 83% self-clean through electrical reversal or direct capacity ๐Ÿฅœ IN A NUTSHELL ๐Ÿฅœ What's the actual market size? Only an estimated 250 of 10 million global industrial facilities have addressed PFAS in wastewater, with perhaps 24 choosing electrochemical oxidationโ€”creating fierce competition for limited installations. How do electrode materials differ? Boron-Doped Diamond offers superior performance but higher costs, while Mixed Metal Oxide and Titanium suboxide provide alternatives, with some companies opting for sacrificial anodes to reduce expenses. What determines system performance? Power density, pH tolerance (46% work at neutral pH), electrode lifetime, and reactor design collectively influence treatment efficiency and operational costs more than any single factor. Are these technologies deployment-ready? Most companies (TRL 7-9) have moved beyond lab-scale, though only Axine and AECOM have reached full commercial deployment with multiple installations. What's the investment opportunity? The collective $120M raised across startups represents capital-efficient validation, with regulatory pressure intensifying and the addressable market potentially growing 10x within three years.

    S13E12 - Can We Actually Afford to Clean Up Forever Chemicals?

    How Can We Afford to Remove PFAS from Our Environment When Treatment Costs Exceed Global GDP? ๐Ÿ™Œ Supporters ๐Ÿ™Œ A big thank you to my partner SimpleLab: https://link.dww.show/simplelab โฌ‡๏ธ IN THIS EPISODE โฌ‡๏ธ PFAS (per- and polyfluoroalkyl substances) are persistent synthetic chemicals used in countless everyday products that contaminate drinking water, wastewater, and the environment. These "forever chemicals" accumulate irreversibly in our bodies and ecosystems, creating mounting health risks for current and future generations while presenting unprecedented economic and regulatory challenges. Dr. Ali Ling is a professor at the University of St. Thomas specializing in PFAS management and wastewater treatment, with a decade of consulting experience helping industrial and municipal facilities address emerging contaminants, and expertise in big-picture systems thinking for environmental risk assessment. ๐ŸŒถ๏ธ KEY SPICES ๐ŸŒถ๏ธ ๐Ÿ’ฐ Cost-Effective Approach - Source reduction is 1,000 times cheaper than environmental cleanup, with upstream industrial controls costing hundreds versus millions of dollars per kilogram of PFAS removed ๐Ÿ”ฌ Technology Expertise - Comprehensive knowledge of GAC, ion exchange, destruction technologies, and emerging treatment solutions across drinking water, wastewater, and industrial applications ๐Ÿ“Š Data-Driven Strategy - Evidence-based analysis showing that removing PFAS at current production rates would exceed global GDP, making source control the only viable path forward ๐ŸŽฏ Risk Prioritization - Understanding that drinking water represents less than 20% of human PFAS exposure, with diet and indoor dust contributing significantly more to health risks ๐ŸŒ Future-Focused Thinking - Emphasis on persistence as a critical factor, recognizing that today's PFAS releases create irreversible accumulation threatening future generations ๐Ÿฅœ IN A NUTSHELL ๐Ÿฅœ Why is cleaning up PFAS from the environment economically impossible? Removing PFAS from the environment at the rate we produce it costs millions of dollars per kilogram and would exceed global GDP, while upstream source control costs only hundreds to thousands of dollars per kilogram. What's the biggest misconception about PFAS treatment? Most people focus on drinking water cleanup as a past problem, but we're still actively producing massive amounts of PFAS today, and drinking water represents less than 20% of human exposure to these persistent chemicals. Should utilities treat PFAS in wastewater effluent? Treating municipal wastewater effluent is extremely expensive and environmentally impactful, whereas addressing industrial discharges and landfill leachate at their concentrated source points is far more cost-effective and logical. How do we prevent regrettable substitution when phasing out PFAS? The European Union is implementing better frameworks that assess both persistence and toxicity before approving chemicals, while companies like IKEA and H&M have successfully phased out PFAS entirely from their supply chains. #๏ธโƒฃ Mentioned Links #๏ธโƒฃ Ali Ling's LinkedIn profile (https://www.linkedin.com/in/lingali/) Ali's paper on the costs to remove PFAS from the environment (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4718530) Hosted by Ausha.
