Turn your biomass into resources

Join the circular economy with AquaGreen's sustainable steam-drying and pyrolysis technology

You transform biomass and waste, like sewage sludge, into renewable thermal energy, soil-improving biochar and/or activated carbon. While doing so, the process eliminates harmful pollutants, reduces greenhouse gas emissions and stores atmospheric CO2 in biochar.
You eliminate greenhouse gas emissions & capture CO2
You reduce environmental pollution & health risks
You recirculate critical nutrients & produce renewable energy
You realize cost savings & turn waste into revenue

Simplify your waste management and reduce handling costs by up to 90%

Your waste management has never been easier. AquaGreen’s continuous, fully automated process uses the waste’s calorific content to fuel its own system. The software-controlled system requires minimal manpower for operation and can be monitored remotely. 

Get your hands on state-of-the-art, patented technology

AquaGreen’s engineers collaborate closely with dedicated partners, senior scientists and professors from relevant universities, including the renowned Technical University of Denmark. Our solution has been recognized by the Solar Impulse Foundation.

Apply steam-drying and pyrolysis to your industry


Our solution turns a problem into a resource for MWWTs. Our solution is commercially viable and supports a transition towards circular economy by re-circulating resources, such as phosphorus.


Livestock manure and other organic waste can be used for energy production, and the biomass can be turned into biochar with the AquaGreen steam dryer and pyrolysis solution.


The trend of growing the smolt bigger before they are moved from land to sea pushes the demand to reduce sludge volumes, to utilize the embedded energy, and to re-circulate valuable resources.

Food & Beverage

When utilizing the AquaGreen solution, the brewery sludge volumes are reduced and turned into valuable biochar. Furthermore, the produced excess thermal energy can be re-circulated and utilized in production.


Sludge, which does not require further processing, matches our combined solution perfectly. Disposal costs are reduced and the excess thermal energy can be re-circulated and utilised in production.


Cruise ships, military camps and festivals generate wastewater sludge, which poses possible health risk. When implementing our solutions, this risk is eliminated, and excess thermal energy can be utilized for e.g. heating.
