KubeKo / Compact digester for biogas

The KubeKo box is a small scale, highly efficient digester that produces biogas from waste. Its multistage design accelerates the fully natural digestion process. This allows a compact layout that can be used by households, communities, farmers and agro-industries that need cooking gas or heat. For larger installations, an electric generator can be installed which produces electricity from biogas. The KubeKo is designed for the use in developing countries where sanitation, clean cooking and access to electricity are among the biggest challenges.
