Technology and Impact
AquaGreen is a technology pioneer within advanced drying and pyrolysis of wet biomass, enabling circulation of one of the world’s largest CO2 contributors (wet waste water sludge & biomass), into scarce nutrients (phosphorus), energy and eventually P2X.
BCSA Model
We invested in AquaGreen based on its clear BCSA profile. The company transforms wastewater sludge into valuable biochar, offering a cleaner, cheaper, and simpler alternative to traditional disposal - with a scalable, modular solution ready for broad deployment.
AquaGreen’s patented technology combines superheated steam drying with pyrolysis to transform problematic sludge into biochar—a clean, nutrient-rich, odorless, and storable material that can be used as fertilizer or refined into activated carbon. The system eliminates over 90% of harmful substances, including microplastics, pharmaceuticals, and heavy metals. In addition, it enables carbon capture and storage by binding CO₂ in the biochar, turning a waste problem into a climate-positive resource recovery solution.
Despite its high-tech design, AquaGreen’s solution is cost-competitive with incineration and land spreading, often resulting in lower total disposal costs. The technology is energy self-sufficient and allows for revenue streams from biochar, thermal energy recovery, and carbon credits, leading to short payback times (typically 2–4 years) and high-margin sales.
The system is delivered as a modular, containerized mini-factory that can be installed onsite at wastewater treatment plants or industrial facilities. It operates autonomously, is fully digitalized, and integrates with local systems. With plug-and-play installation and remote monitoring, the solution removes the complexity of coordinating multiple vendors or handling waste logistics, while improving compliance and traceability.
Built from standard industrial components, the solution can be rapidly assembled and deployed using outsourced production and local installation teams. AquaGreen has already delivered operational units and secured municipal contracts, with a structured market-entry strategy ready for scale across verticals and geographies. The modular design and planned “as-a-service” model further support scalable and repeatable expansion.
