The biogas industry<\/strong> is undergoing change: instead of traditional energy crops, biogas plant operators are increasingly turning to residual materials and agricultural by-products<\/strong>. This is due to changes in the Renewable Energy Sources Act (EEG), which limit the use of maize and have abolished the bonus for renewable raw materials. This is shifting the focus to cost-effective alternatives such as green waste, straw, manure, poultry manure and flowering plants<\/strong>.<\/p>\n\n\n\n

However, many of these substrates have hardly been studied to date. There is a lack of reliable data on the degradation rate<\/strong> and methane formation potential<\/strong>.<\/p>\n\n\n\n

Challenge: Existing processes are expensive and time-consuming<\/h2>\n\n\n\n

The tests currently available for substrate characterisation are predominantly designed for traditional energy crops. Methods from feed analysis can only be applied to a limited extent. Gas yield tests do exist, but they are expensive and time-consuming:<\/p>\n\n\n\n
