Climate relevance and energy efficiency of biogenic waste recovery (KEVBA)
Description
The report of the Federal Environment Agency compares the composting and fermentation of biogenic waste with regard to climate relevance and energy efficiency. Greenhouse gas balances for open and partially closed composting as well as wet and dry fermentation are calculated. In the fermentation processes, different variants of the fermentation residue treatment as well as different uses of the generated biogas (electricity generation, heat utilization, biomethane production) are examined. Composting has a worse greenhouse gas balance than fermentation. The greenhouse gas balances of the fermentation variants vary greatly depending on the waste. The best results are achieved in the processing of biogas into biomethane. Open digestate storage can lead to high greenhouse gas emissions and should therefore be covered gas-tight.
