minus CO2 by carbonauten: carbonauten has developed a system for industry, companies, and municipalities that immediately and effectively reduces CO2 emissions and costs. It includes the production of an innovative material category NET Materials® (Negative Emission Technology). The NET Materials® consist of a combination of CO2-lowering biocarbons with different binders. The biocarbons are produced worldwide at decentralized locations from local biogenic residues and problematic substances by means of a further developed pyrolytic carbonization. As an attractive by-product, large amounts of excess, base-load renewable energy are created. Each ton of carbonauten biocarbon permanently stores up to 3.3 tons of CO2.
