AquaGreen

AquaGreen is a Danish cleantech company that has developed a technology for treating wastewater sludge and converting low-grade biomass into renewable energy and biochar. The company's process utilizes steam drying and pyrolysis to transform sludge into a valuable resource, addressing the challenges of sludge disposal and resource scarcity.

The company's primary clients are municipal wastewater treatment plants and industries that generate organic waste. AquaGreen's HECLA® plant is designed to be integrated into existing infrastructure, offering a decentralized solution for sludge management. The business model revolves around the sale and installation of these plants. By converting waste into biochar, a product with applications in agriculture and soil improvement, the company creates an additional revenue stream for its clients.

The market for AquaGreen's technology is driven by increasing environmental regulations, the need for sustainable waste management solutions, and the growing demand for renewable energy sources. The company's process also contributes to the circular economy by recovering phosphorus, a finite and essential nutrient, from the sludge.
