The Biogas Lifecycle
Bedfordshire based Flow Components has been involved in a number of Anaerobic Digestion & Biogas projects and supplied ATEX approved Electric Actuators, Pneumatic Actuators, Ball Valves, Butterfly Valves and Solenoid Valves from stock. This is a look at the Lifecycle of a Biogas Power Plant:
- Waste food from households and cooking fats are fed in to the plant
- Grass, corn and other organic matter is added which acts as food for the micro organisms
- Animal wastes such as slurry, manure and dung are also added. It’s far from glamorous!
- The fermenter is heated up to 40 °C and the mixture is decomposed by the micro organisms within. This process happens with no light or oxygen.
- Once the mixture has been fermented it is transported to storage tanks
- This residue can be used as a high quality agricultural fertiliser both wet or dry
- The Biogas generated is stored and burned to generate electricity and heat
- Some Gas is sold as fuel for use in service stations or industry
- Electricity is then sold and returned to the Power Grid
- Any heat generated is used to warm buildings or to dry harvested crops / timber
These Biogas plants are a great way to make money from waste and are very popular with Farmers and local councils.
