Biochemical material use of lignite
For the OxiHumin project, regionally available lignite or by-products from briquette production are used as raw materials and made available for the production of humin-based products.
The innovation consists of adding suitable microorganisms to brown coal of different origins or by-products from briquette production with relatively low humic acid contents, in this way biochemically oxidising them to humic acids and, among other things, improving their suitability as soil additives.
This project is funded by the European Union and the State of North Rhine-Westphalia.
