What CarboREM does
CarboREM is an Italian industrial technology company headquartered in Lavis (Trentino), and operates as a wholly-owned subsidiary of Greenthesis S.p.A. The company develops and commercializes industrial-scale plants based on a patented Hydro-Thermal Conversion (HTC) process that converts wastewater sludge into hydrochar while continuously recovering ammonia. The technology is positioned as a circular-economy solution: it achieves an average 60% dehydration rate with three times the effectiveness of conventional bio-drying, produces a sterilized, pathogen-free slurry output, and yields hydrochar usable in paper and cardboard production. CarboREM's commercial offering centers on two plant models — the compact C700 for smaller facilities and the high-capacity C5000 for larger municipal and industrial applications — together with supporting engineering and laboratory services.
The company sells directly to municipal and industrial wastewater treatment operators through an enterprise field-sales motion, supported by industry trade-show presence (including Ecomondo 2025), content marketing, and a bilingual Italian/English website. Pricing is quote-based and tied to multi-year contracts for capital equipment installation. CarboREM's primary customer segment is municipal wastewater treatment facilities, with industrial wastewater treatment facilities articulated as a secondary vertical; the Liscate municipal C5000 plant (inaugurated October 2025) serves as the flagship reference installation. Revenue is generated through hardware sales and professional services, with no disclosed figure, no external funding history, and limited public financial information beyond a registered share capital of approximately €70,431. Ownership and corporate control rest entirely with parent Greenthesis S.p.A.

CarboREM product offering
Product offeringCore offering
CarboREM designs, manufactures, and sells industrial-scale Hydro-Thermal Conversion (HTC) plants (C700 and C5000 models) that convert wastewater sludge into hydrochar through a patented hydrothermal carbonization process featuring continuous ammonia recovery and producing pathogen-free, easily dewaterable slurry output. The company also provides engineering and laboratory services to support plant installation, optimization, and operation for municipal and industrial wastewater treatment clients.
Product overview
CarboREM, a subsidiary of Greenthesis S.p.A., offers a portfolio of industrial sludge treatment solutions based on its proprietary Hydro-Thermal Conversion (HTC) technology. The product line consists of two main plant types: the compact C700 for smaller operations and the high-capacity C5000 for larger industrial applications. The HTC process achieves 60% average dehydration rates and is three times more effective than conventional bio-drying methods. The company also provides engineering and laboratory services to support plant operations.

CarboREM competitors and assessment
Company assessmentDirect peers
- Huber SE: Huber SE is a German manufacturer of equipment for water, wastewater, and sludge treatment, including sludge dewatering, drying, and thermal treatment systems. It directly competes with CarboREM in the municipal and industrial sludge processing equipment market, offering alternative mechanical and thermal solutions.
- SunCoal Industries: SunCoal Industries is a German engineering and technology company that builds CarboREN-style HTC plants for converting sewage sludge and other wet biomass into coal substitute. It competes head-to-head with CarboREM in the municipal and industrial sludge-to-hydrochar space with similar technology positioning and customer base.
- AVA-CO2: AVA-CO2 is a Swiss-German company specializing in hydrothermal carbonization (HTC) technology for sewage sludge and organic waste valorization, including its own HTC plant references. It is a direct competitor to CarboREM, addressing the same municipal and industrial wastewater treatment market with a similar HTC platform.
- TerraNova Energy: TerraNova Energy (formerly Carbon Solutions) is a German company pioneering hydrothermal carbonization (HTC) of organic residues into 'terra preta'-style carbon. It is one of the closest direct competitors to CarboREM, using the same HTC process family to convert wet organic waste streams into carbon-based products for industrial and agricultural end-markets.
Broad incumbents
- Alfa Laval: Alfa Laval is a Swedish industrial equipment manufacturer supplying heat exchangers, separation, and fluid handling equipment used in sludge treatment and wastewater applications. It overlaps with CarboREM as a supplier of process equipment to the same municipal and industrial wastewater treatment customer base.
- Andritz: Andritz is a large Austrian industrial group supplying equipment and plants for municipal and industrial sludge treatment, including thermal drying and dewatering systems. It is a broad incumbent offering overlapping capabilities to CarboREM's C700/C5000 HTC plants, but as part of a much wider pulp, paper, hydromechanical, and environmental technology portfolio.
- Suez: Suez is a major French environmental and water services group providing wastewater treatment and sludge management solutions, including its own thermal and biological treatment technologies. It competes with CarboREM indirectly via its municipal wastewater treatment operations and related sludge valorization offerings.
- Veolia Environnement: Veolia is a global environmental services leader operating wastewater treatment plants and offering sludge management solutions across municipal and industrial customers. It is a broad incumbent that competes indirectly with CarboREM — both addressing the same end-customers' sludge disposal pain points, though Veolia primarily operates treatment facilities rather than manufacturing HTC equipment.
Emerging players
- Hitachi Zosen Inova: Hitachi Zosen Inova (HZI) is a Swiss-Japanese company that builds anaerobic digestion and thermal treatment plants for organic waste and sludge. It is an emerging adjacent player addressing the same waste-to-resource opportunity as CarboREM, with a complementary rather than identical technology stack.
- Cambrian Innovation: Cambrian Innovation is a US-based clean-tech company providing industrial wastewater treatment and resource recovery solutions, including systems that recover energy and nutrients from industrial waste streams. It is an emerging player addressing a similar problem space (industrial wastewater valorization) with a different technical approach.
