Table 2 Parameters of system components

Biogas recovery system

Number of pigs: 45, volume of biogas tank (material: composite): 14 m³, the biogas recovered is used for cooking at dyeing pan and other living activities (at kitchen).

Wastewater treatment plant

Total volume of wastewater treatment plant (compacted as a block): 10 m³, having 4 compartments (anaerobic combined with filter), wastewater treatment loading capacity (accordance with BOD₅): 1.087 kg/day. Volume of water hyacinth pond: 80 m³ which corresponds to wastewater treatment loading capacity (accordance with BOD₅): 7.35 kg/day.

Composting system/tank

Composting area is 4 m², materials: 100 kg pieces of sedge + 1 kg Trichoderma (bio-product), incubated for 30 days, the moisture of 50-55 % is kept by watering with wastewater flow after biogas tank, and the temperature during composting process is kept by covering the tank surface.
