About C-Green
Traditional sludge disposal methods, such as landfilling or agricultural use as fertilizer, are facing increasingly strict environmental regulations—and in some areas, outright bans—leading to rising sludge handling costs. In this shifting landscape, C-Green has a clear and vital role to play: providing sustainable, efficient, and future-proof solutions for sludge management.
Our vision is to be a global actor in sustainable sludge and wet organic waste handling solutions and contribute to a climate-neutral and circular society. Founded in 2014, we are a Swedish company with headquarters in Solna, just outside of Stockholm. Our headquarter is equipped with a customized, state-of-the-art lab and we operate a mobile pilot plant. Among the company’s owners are leading innovation investors, green technology specialists, major financial institutions, and individuals with strong industrial and financial networks.
