Revenue model
- Capital equipment sales (HECLA Setores systems): AquaGreen sells HECLA Setores 1.000 and 1.500 pyrolysis plants to wastewater utilities and municipalities. Plant prices are approximately 12-15 million DKK per unit (for smaller installations), with large central plants representing investment up to 35x that amount. Plants can be produced in 8-12 weeks.
- Operating cost savings for customers: Utilities reduce sludge disposal costs (90% volume reduction) and eliminate expensive PFAS disposal fees. The process also generates sustainable thermal energy (approximately 2,000 MWh per 1,000 tonnes dry matter treated per year) that can be used on-site or sold for district heating.
- Carbon removal credits (CDR/CORCs): Utilities can generate and sell Carbon Dioxide Removal Certificates from biochar carbon sequestration. Carbon market prices currently range around 100-150 EUR per tonne CO2e. Approximately 500 tonnes of carbon stored per 1,000 tonnes dry matter treated.
- Biochar and thermal energy sales: Biochar is sold as a soil improver for regenerative agriculture, as a substitute to activated carbon, or for use in construction (replacing fossil-based carbon materials). Thermal energy from the process can be sold to district heating networks.
- Managed services / plant operation: Alternative model where AquaGreen installs the plant and customers pay for utilization of the service, with AquaGreen handling sludge or biomass management.

AquaGreen product offering
Product offeringCore offering
AquaGreen designs, manufactures, and sells the HECLA® Setores integrated steam-drying and pyrolysis system, the world's first autothermal system of its kind. The equipment converts municipal wastewater biosolids into carbon-sequestering biochar through a two-stage process (steam drying at ~200°C and pyrolysis at ~650°C), eliminating 99% of organic pollutants (PFAS, PAHs, microplastics, pharmaceuticals) and recovering nutrients like phosphorus. AquaGreen also offers a managed-service model where it installs and operates plants on behalf of customers.
Product overview
AquaGreen offers the HECLA® Setores product line, the world's first autothermal integrated steam-drying and pyrolysis technology for municipal wastewater biosolids management. The product portfolio consists of two model sizes: HECLA® Setores 1.000 (compact unit processing 850 tonnes/year dry matter) and HECLA® Setores 1.500 (larger unit processing 1,300 tonnes/year dry matter). Both units convert wastewater sludge into carbon-sequestering biochar through a fully automated continuous process that eliminates 99% of environmental pollutants including PFAS, PAHs, microplastics and pharmaceutical residues, while recovering phosphorus and other nutrients. The technology achieves 90% volume reduction and supports competitive ROI periods of 4-11 years for wastewater utilities.

AquaGreen partnerships and signals
Strategic signalPartnerships
Three partnerships are on record, tiered flagship and secondary.
- Thames WaterflagshipThames Water, the UK's largest water and wastewater utility, selected AquaGreen as technology provider for the UK's first continuously operating sludge-fed integrated steam-drying and pyrolysis demonstration plant at Crossness Sewage Treatment Works in South East London. The project is part of Ofwat's Water Breakthrough Challenge (Transform) and aims to prove sewage sludge pyrolysis as a scalable circular solution. Plant expected operational mid-2027. CEO Thomas Nygaard Hamann called it a crucial step for international expansion and validation of years of engineering work.
- Technical University of Denmark (DTU)secondaryAquaGreen collaborated with researchers from the Technical University of Denmark to develop and launch the world's first integrated steam-drying and pyrolysis plant. The academic partnership contributed to the technical development and validation of the HECLA Setores technology.
- Odsherred ForsyningflagshipOdsherred Forsyning is the first municipal utility to receive local approval (from Odsherred City Council) for expansion with a combined sludge drying and pyrolysis plant — described as the world's first facility of its kind. This reference site has been a cornerstone reference for AquaGreen's commercial track record.

AquaGreen competitors and assessment
Company assessmentBroad incumbents
- Veolia Environnement: Global environmental services giant operating municipal water and wastewater contracts, including biosolids management via incineration and other thermal pathways. Veolia's broad portfolio overlaps with AquaGreen's wastewater utility customers and competes for the same municipal procurement budgets, though it does not specialize in integrated pyrolysis.
- Suez SA: Major water and waste management operator with established municipal utility relationships across Europe. Like Veolia, Suez offers sludge treatment services and competes in biosolids management, but its portfolio is broad and not specialized in autothermal pyrolysis technology.
Direct peers
- Pyreg GmbH: German pyrolysis technology company producing carbonization systems that convert biomass and organic residues into biochar. Pyreg is a direct competitor to AquaGreen in the European pyrolysis/biochar market, targeting similar waste-to-resource use cases though typically at smaller scale and different feedstock focus.
- C-Green Technology AB: Swedish technology company specializing in hydrothermal carbonization (HTC) of wet biomass and biosolids. C-Green is a direct Nordic competitor offering an alternative sludge-to-biochar pathway, with comparable municipalities and agricultural end markets, though the technology differs from AquaGreen's autothermal pyrolysis approach.
- Carbofex Oy: Finnish company operating industrial-scale pyrolysis plants to convert biomass into biochar, with associated carbon credit sales. Carbofex is a direct Nordic competitor to AquaGreen in the biochar/pyrolysis space, though typically focused on woody biomass rather than biosolids.
- ETIA S.A. French pyrolysis technology provider offering biomass and organic waste-to-biochar systems. ETIA is a direct competitor in industrial-scale pyrolysis equipment and biochar production, targeting similar industrial and municipal residue streams in Europe.
Emerging players
- Anaergia Inc. Canadian cleantech company providing anaerobic digestion and resource recovery solutions for organic waste and biosolids. Anaergia targets overlapping municipal customers with alternative thermal/biological pathways, partially overlapping with AquaGreen's biosolids-to-resource thesis.
- TerraTherm S.A.S. French thermal desorption and sludge treatment specialist serving municipal and industrial customers. TerraTherm addresses sludge management with thermal treatment, partially overlapping with AquaGreen's pyrolysis approach but generally focused on contaminated soils and industrial sludges.
- Cambrian Innovation: US-based cleantech company offering wastewater-to-resource solutions including biomass-to-energy and water reuse for industrial and municipal customers. Cambrian overlaps with AquaGreen in the wastewater resource recovery thesis and serves similar circularity-driven customer use cases.
Others
- Feralco Group (FMG Circular Invest): European water treatment chemicals supplier (and AquaGreen investor via FMG Circular Invest) serving 100M+ people. Feralco is an ecosystem participant — supplier, investor, and indirect channel partner in the water sector — rather than a direct technology competitor.
