The disposal and treatment of biological waste are major challenges for many industries. Anaerobic fermentation—a superior alternative to composting—provides a unique solution for the management of a wide range of organic substances. Created during anaerobic fermentation, biogas serves as a high-energy, renewable fuel that can be used as a substitute for fossil fuels. Biogas engines not only improve waste management, but also generate an economical energy supply.
How It Works
The process of biogas generation is divided into three steps: Preparation of the bio-input, fermentation, and post-treatment of the residual material.
At the start, the organic material is collected in a primary pit, sterilized to remove harmful germs in case of food waste and moved to the digester. The biogas produced in the digester is collected in a gas storage tank to ensure a continuous supply of gas, independent of fluctuations in the gas production. Finally, the biogas is fed into a gas engine. For safety reasons, the installation of a gas flare is recommended so that excess gas can be burned off in the event of excessive gas production.
