Biochar in industry
The possible uses of biochar (pyrolytically produced biomass carbon) are extremely varied. Not only agriculture can benefit from the environmentally friendly charcoal. It also has numerous positive effects when used in industrial processes. Mainly in the form of activated carbon (adsorbent) in water, gas and air purification, but also as a reducing agent in metallurgical processes, biochar has great potential.
Last but not least, biochar is beneficial because it substitutes fossil fuels and thus improves the CO2 footprint. Cement and lime plants, for example, require considerable quantities of energy sources to provide the necessary process temperatures. For economic reasons, most cement plants already use waste-based fuels on a large scale. However, these fuels are often not available in a form that allows them to be used via the main burner. In order to replace fossil fuels (coal, oil, gas), biomass carbonates are also suitable, as they have similar properties to the brown coal dust conventionally used (see Weber 2016: Biokohle. Herstellung, Eigenschaften und Verwendung von Biomassekarbonisaten, p. 279–282 (Biochar. Production, properties and use of biomass carbonisates)

Pollutants from soil, water and gases can be removed with biochar. According to Weber (Industrielle Anwendungen von Biomassekarbonisaten. Adsorptionsmittel, in: Quicker/Weber 2016, Biokohle), these can be organic pollutants…
The production of metallic raw products is one of the most important industrial sectors. Germany, for example, is one of the world’s leading countries in the production of steel, aluminium, lead, copper and tin. According to the authors Schulten…
Biochar is far too valuable to be used only as soil improver and carbon storage. It has been used by generations of people for drinking water filtration, the treatment of waste water and kitchen waste and as composting agents. In today’s world, uses are multiplying…
