Biogas
Biogas, primarily composed of methane and CO2, is produced through the anaerobic digestion of organic materials such as agricultural waste, food scraps, and sewage.
Sewage sludge is an energy- and nutrient rich by-product of wastewater treatment plants. Depending on its origin or composition, after treatment the sludge can be used for:
- Fertilizer and return to the soil
- Burned and used in incineration units to recover the energy
- Stored in anaerobic digesters for 20 days to produce biomethane
What’s more, biogas production produces digestate, a useful byproduct that can be used as fertilizer in agriculture. So, in addition to clean energy, you get an efficient waste management system. This reduces methane emissions and significantly lowers the carbon footprint.
Energas offers the following equipment to the South African Biogas Industry.
