ALKIA’s modern technologies take advantage of the fermentation process in natural biodegradable materials to generate energy using a fuel that is both efficient and environmentally sound: biogas. The mixture of methane and carbon dioxide provides aprox. 5.5KWh/m3 and offers a clean alternative to fossil fuels. Also treatment of waste water and digestion of sewage sludge produces sewage gas containing methane. We utilise this energy-rich gas in our co-generation power plants to generate energy efficiently. The resulting quantities of heat and power make it possible to supply clients’ plants with electricity and heat.
