C-Green is a Swedish clean-tech company that enables the harvest of energy and the nutrients phosphorus and nitrogen from wet waste and effectively reduces greenhouse gas emissions from sludge handling. We capture the carbon in sludge and concentrate it in HTC hydrochar, a dry sterile material that can be used as biofuel to replace fossil fuels, as soil improvement or as a resource for secondary source mining. Recently, a potential application of hydrochar called BioBooster, has been identified which may dramatically increase biogas production in existing biogas plants and thereby reduce the use of fossil fuels. C-Green’s headquarters in Stockholm are equipped with a customized, state-of-the-art lab for sludge analysis. Our two mobile plants - one for HTC and one for wet oxidation - together make up our mobile biorefinery that can process wet waste at customer sites.
