C-Green utilizes hydrothermal carbonization (HTC) technology to convert wet biowaste into sterile, dry biocoal, effectively addressing the challenge of massive sludge disposal from wastewater treatment. This process not only eliminates greenhouse gas emissions but also recovers valuable nutrients, providing a sustainable energy source and reducing overall disposal costs.

Problem
Wastewater treatment produces massive amounts of sludge, creating a significant disposal challenge. Traditional sludge disposal methods are costly, environmentally damaging, and often result in greenhouse gas emissions.
Solution
C-Green offers a solution to sludge management through its OxyPower HTC™ (Hydrothermal Carbonization) technology, which converts wet biowaste into sterile, dry biocoal. This process eliminates greenhouse gas emissions associated with sludge decomposition and reduces the volume of waste requiring disposal. The resulting biocoal can be used as a biofuel, a carbon sink, or as a soil improvement product, offering a circular approach to waste management. The OxyPower HTC™ process also facilitates the recovery of valuable nutrients like nitrogen and phosphorus from the biowaste.
Target Audience
The primary target audience includes municipal wastewater treatment plants and industrial facilities dealing with large volumes of wet biowaste, particularly in the Baltic region.
Features
- Converts up to 30,000 tons of wet biowaste into biocoal annually per facility.
- OxyPower HTC™ technology eliminates greenhouse gas emissions from sludge.
- Produces sterile biocoal, destroying viruses, bacteria, and parasites.
- Biocoal can be used as a biofuel, carbon sink, or soil amendment.
- Enables recovery of nitrogen during the HTC process.
- Facilitates phosphorus recovery from biocoal incineration ash.
- Energy-efficient process with potential for self-sufficiency.
