River Blueprint is developing a circular biogas plant in Ghana that converts invasive aquatic plants into electricity, organic fertilizers, and carbon credits. Three contractual revenue streams. Proven technology. A bond with a 9.5% annual coupon rate, quarterly payments, and investment insurance from the Dutch State.
Invasive aquatic plants are spreading rapidly across Lake Volta. The ecological and economic consequences are significant: disruption of the ecosystem, blockage of hydroelectric power plants, and increased methane emissions from decaying biomass. Existing control methods are costly, temporary, and not operationally scalable.
“There was no definitive solution to the invasive water pest. Until now“
What is waste to others is a raw material to us. In four steps, we transform a growing problem into energy, bio-fertilizer, and impact.
Invasive aquatic plants are removed from Lake Volta daily. The biomass is immediately transported for processing, ensuring it does not return to the ecosystem.
In closed reactors, biomass is processed via anaerobic digestion. This produces biogas, which is used for energy production.
The biogas is converted into green electricity for Ghana’s national electricity grid.
After fermentation, valuable nutrients remain. These are processed into organic NPK fertilizer for the agricultural sector. In addition, CO₂ reduction is achieved, which can be converted into carbon credits.
What starts as a local environmental problem grows into a scalable solution with global impact. With measurable results such as sustainable energy, CO₂ reduction, and ecosystem restoration, we show how ecology and economy come together.
fresh aquatic plants — harvested, ground, stored in storage tanks
Fully automatically fed from storage tanks. Anaerobic digestion.

green power — from biogas
organic NPK fertilizer — filtered, dried, pressed
CO₂e avoided — carbon-negative process
River Blueprint combines ecological impact with a strong, scalable business model. The raw material is free. The impact is global. The return is tangible.
River Blueprint collaborates with technology partners, local governments, and international financiers to realize projects where they are needed most. This collaboration forms the foundation of our organization.
