Biogas Production
Organic waste is used for biogas production. These are:
- Animal manure (cattle, sheep, poultry)
- Plant production waste
- Forest and paper industry waste
- Textile industry waste
- Sewage waste
- Food industry waste (milk, yeast, chocolate, beverage production, etc.)
- Agricultural industrial waste (oil, sugar factories, etc.)
- City solid waste
Biogas is a flammable gas mixture obtained by decomposing organic wastes by microorganisms in an oxygen-free environment. In the process:
Methane (CH₄): It is the most important component of biogas and constitutes its energy source
Carbon dioxide (CO₂): It is a natural by-product of the process.
Hydrogen sulfide (H₂S) and nitrogen (N₂): May be present in small amounts depending on the type of waste.
The methane content determines the energy value of biogas. However, methane cannot be liquefied at low pressures like LPG; It needs a pressure of 280-350 bar to liquefy.
Biogas production depends on the chemical and physical properties of the wastes used . Important factors include:
- Type and composition of waste (animal, vegetable, domestic, etc.)
- The amount of foreign matter (soil, stone, metal, etc.)
- Particle size (smaller pieces ferment faster)
- Moisture content and organic matter content
- Generator (reactor) design (volume, insulation, mixing and heating systems)
- Fermentation temperature and pH balance
