- Biog Gas Production
- Batch Generators
- By products cleared away at the end of each session
- Manually loaded with waste to produce biogas in batches
- Generators
- Continuous generators are more expensive because waste has to be mechanically pumper in and digested material mechanically removed constantly
- Batch generators less convenient because waste fed in manually
- Generator best located near waste source
- 35 degrees for maximum biogas production
- Continuous Generators
- Make biogas all the time
- More suitable for large scale biogas projects
- Wadte continuallyfed in and biogas produced at a steady rate
- MADE BY anaerobic FERMENTATION OF WASTE MATERIAL
- 70% methane 30% CO2
- Microoganisms ferment plant and animal waste whch contain carbohydrates
- Can't be stored as a liquid, has to be used immediately for heating
- Environment and Economy
- Raw material is cheap and easily avaliable
- 'Greener' than fossil fuels said to be carbon neutral
- Stops developing countries collecting wood for fuel-efficient waste disposal
- Otherwise wast could cause spread in disease
- Slurry used as fertiliser
- Better tan normal fertiliser - more crops
- Doesn't produce much SO2 or nitrogen oxides which cause acid rain
- ETHANOL
- Anaerobic fermentation of sugar
- GLUCOSE -> ETHANOL + CO2 +ENERGY
- Anaerobic fermentation of sugar
- Batch Generators
