„Thanks to precise controlling and adjusting of several process parameters, our modern carbonisation plants for the first time allow for the reliable production of premium biochar without harmful by-products, which includes the production of feeding char.”


Feeding char


  • Generally improved state of health and care
  • Increase in feeding efficiency
  • Reduction of cell counts in milk
  • Increase in egg production and quality in poultry
  • Improvement in stable hygiene and odor pollution

(first effects can already be observed after 1 to 4 weeks following the first application of biochar)


Soil char


  • Substantially improves soil fertility
  • Increases retention capability in humus-poor and sandy soils
  • Loosens heavy and compressed soils
  • Stores up to 5 times its own weight in water including the nutrients dissolved therein
  • Offers an optimal habitat for microorganisms
  • Active contribution to climate protection
