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


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.


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.


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.

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.


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.


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

Odsherred Forsyning has made a video explaining the benefits of their installation

With an AquaGreen HECLA® Setores 1,000 plant, you can reduce greenhouse gases by 1,800 ton CO2e, produce 2,000 MWh energy, and store 500 ton carbon in biochar. The resulting biochar is odorless and has a content of 5-6% plant-accessible phosphorus.

AquaGreen is a Danish engineering company within cleantech

backed by Nordic Alpha Partners & the Danish Workers Pension Fund (ATP), developed and patented with the Technical University of Denmark (DTU), and recognized by innovation awards.
