Substrates for biogas plants

The qualified team of engineers at Krieg & Fischer has extensive experience of different processing techniques and substrates – ranging from complex pre-treatment techniques for biowaste to fermentation technology, right through to the required post-treatment. Not only are we experts in "conventional" substrates, we also develop solutions for all kinds of substrates such as semi-frozen yak dung, elephant dung, olive residues, straw or slaughterhouse waste. We develop the best pre-treatment for waste which contains impurities, such as biowaste or the organic fraction of residual waste. Our long-standing practical experience ensures the best possible outcome for our customers.
