carbonauten is the minus CO2 factory and 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). 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. Every ton of carbonaut biocarbon permanently stores up to 3.3 tons of CO2. minus CO2 - if not now, then when?
