Substrates

In order to have a cost-effective biogas production, it is necessary to use materials with large gas potential, so let’s see which raw materials are suitable. The table below shows some of the suitable raw materials, but there are also plenty of other materials that can be used. It’s a pretty good comparison when we say that the digester can process everything cows can digest. The best situation would be if we owned the substrates, or if we were in position to procure substrates which are a waste in someone else’s production, and the manufacturer has expense for its removal.
