„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

  • Reduction of hoof and foot diseases
  • Reduction of diarrhoeal diseases
  • Increase in feeding efficiency

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