TreaTech

What TreaTech does

TreaTech is a privately held Swiss cleantech company founded in 2015 by EPFL Life Sciences and chemical engineers, headquartered in Lonay, Switzerland. The company develops and commercializes a patented catalytic hydrothermal gasification (cHTG) process that operates under supercritical water conditions (T > 374°C, p > 221 bar) to convert a broad range of liquid and wet waste streams into three reusable outputs: a methane-rich renewable gas, clean water, and mineral nutrients (phosphorus, nitrogen, potassium). The technology has been validated across more than 20 industrial feedstocks, reports 99% conversion of organic carbon to gas, greater than 99.8% destruction of PFAS compounds, and up to 94% lower CO2eq emissions compared with incineration.

The company's commercial offering consists of modular cHTG units deployed directly at customer sites — branded as the VISTA unit for its first commercial deployment at waste management firm Ecorecyclage's Lavigny facility in Q3 2024. TreaTech targets industrial manufacturers in chemicals, pharmaceuticals, oil & gas, and food & beverage, plus municipal wastewater treatment plants facing tightening regulation of sewage sludge and phosphorus recovery. The go-to-market is enterprise field sales with a multi-step validation cycle (customer discovery → prototype testing → feasibility study → bespoke engineering agreement → on-site commissioning), supported by partnerships with ENGIE, Montrose Environmental, Shell Catalysts & Technologies, Technip Energies, AB InBev, GRTgaz and BASF.

TreaTech monetizes hardware sales and on-site commissioning for the modular treatment units, with emerging optionality on licensing and royalty arrangements for technology replication at multiple customer sites. The company has raised approximately CHF 13.4 million in disclosed funding to date, anchored by a CHF 9 million Series A in June 2023 led by Engie New Ventures and Montrose Environmental Group, supported by non-dilutive grants from the Swiss Federal Office of Energy, the European Innovation Council, and Innosuisse. Operations are organized around a team of approximately 10 specialists focused on technology validation and scale-up engineering.

Revenue model

1. On-site Waste Treatment Equipment Sale and Commissioning: TreaTech builds, sets up, and commissions treatment equipment on-site by connecting it to the customer's existing infrastructure. Revenue is generated from the sale and installation of custom-designed modular treatment units, followed by ongoing operational support. Business model involves customized technical design and financials per customer.
2. Modular Circular Waste Treatment Unit (VISTA): First commercial VISTA unit installed at Ecorecyclage's Lavigny site in Q3 2024. Unit validates continuous 24-hour/day organic waste treatment capability at a waste management facility. Revenue model based on deploying proprietary treatment units at customer sites.
3. Licensing and Technology Deployment: Technology is modular and can be adapted to fit existing on-site processes. Potential licensing model for deploying technology at multiple sites with support from TreaTech's technical team.

Core offering

TreaTech develops, builds, and commissions modular Catalytic Hydrothermal Gasification (cHTG) treatment units that convert industrial and municipal liquid waste streams on-site into three outputs: grid-ready methane-rich renewable gas, clean water, and mineral nutrients (phosphorus, nitrogen, potassium). The technology operates at supercritical water conditions (T>374°C, p>221 bar) and is sold as a customized engineering solution with on-site installation and commissioning, targeting chemical, pharmaceutical, oil & gas, food & beverage manufacturers, and municipal wastewater treatment plants.

Product overview

TreaTech offers a single unified product based on its patented catalytic Hydrothermal Gasification (HTG) technology. The core technology converts waste streams under supercritical water conditions into three valuable outputs: methane-rich renewable gas (grid-ready), clean water (90% recovery rate), and mineral nutrients (phosphorus, nitrogen, potassium). The product is offered as a modular, scalable solution that can be adapted to fit customer existing on-site processes. The VISTA Unit represents their first commercial-scale deployment at Ecorecyclage in Switzerland.

Direct peers

• Licella Holdings: Australian company using Catalytic Hydrothermal Reactor (Cat-HTR) technology to convert waste into fuels, chemicals, and recovered resources. Most direct technical comparable to TreaTech's cHTG process, operating in the same feedstock-to-product category with similar end markets in circular economy.
• Mura Technology: UK-based company using supercritical water technology (Cat-HTR licensed in part from Licella) for plastic-to-chemicals recycling. Directly comparable supercritical water process and waste-to-resources value proposition targeting petrochemical and consumer goods customers.
• Anaergia: Canadian-listed company (ANRG) converting organic waste streams into renewable energy (biogas) and recovered resources for industrial and municipal customers. Same vertical focus on organic waste-to-energy with on-site and centralized solutions and overlapping customer base.
• Enerkem: Canadian waste-to-methanol and chemicals company using gasification to convert non-recyclable waste into commodity outputs. Directly comparable in turning residual waste into marketable fuels/chemicals for industrial customers, though using syngas/methanol pathway rather than methane.

Emerging players

• Electrochaea: Power-to-methane company using biological methanation to produce renewable methane from CO2 and green hydrogen. Competes in the renewable methane market via a fundamentally different pathway (synthetic CH4) rather than from organic waste, but addresses the same end-product opportunity.
• SunFire: German company producing renewable e-fuels and synthetic gases via power-to-X (electrolysis + reverse water-gas shift / methanation). Competes for the renewable methane/e-fuel customer wallet with different feedstock economics (hydrogen/CO2) rather than organic waste.
• Gradiant: US-based water technology company focused on industrial wastewater treatment, water reuse, and resource recovery (including critical minerals). Adjacent technology overlap in clean water and mineral recovery from industrial streams, sharing TreaTech's circular-economy value proposition for industrial customers.

Regional players

• Nature Energy: Denmark's largest biogas producer, operating large-scale anaerobic digestion plants across Northern Europe. Competes for the European renewable gas end-market via a more mature but lower-margin pathway, serving similar municipal and industrial customers.

Broad incumbents

• Veolia: French multinational operating waste management, water services, and energy services globally. Engie (TreaTech's lead investor) partner and dominant incumbent in TreaTech's target industrial and municipal customer base that could adopt or compete with on-site waste-to-gas.
• Suez: French multinational in water management and waste recovery with strong European municipal and industrial footprint. Broad incumbent in the same waste/water markets TreaTech targets, with the resources to acquire or replicate circular waste-to-resource capabilities.
