Broiler poultry farms raise poultry on bedding. But sometimes there is dung without bedding. In principle, a biogas plant for broiler poultry farms are similar to a biogas plant for egg poultry farms. There are 6 methods: 1) dilution with sewage water, 2) adding carbon-rich organics like fat or silage, or 3) ANA-strips with gypsum, 4) dry batch method, 5) enzymatic digestion of bedding, 6) using thermal-pressed straw bedding
In the case of dung with bedding, it is necessary to install an additional chopper. The bedding can be very different: wheat and rice straw, sawdust, and rice and sunflower husks. In the process chain, a chopper is installed between the solid feed loader and the reactor.
An alternative to processing with the classical CSTR technology, may be a dry process with a dry batch or a garage type reactor. Bedding serves as a scarifier so that the percolate can percolate through the dung.
The best practice of biogas biogas plants at chicken farms is using fatty pulp from a slaughter house
The NGE Biogas team employs specialists with unique experience in the design of biogas plants specifically for breeder farms. The entire team of designers joined NGE Biogas. Before NGE Biogas, the specialists designed biogas plants for the world's largest chicken breeder MHP: 5 MW in Elizavetovka and 20 MW in Ladyzhin both with bedded dung.
In addition to these plants, NGE Biogas has its own experience in designing a 1 MW biogas plant for Kurma poultry farm in Kazakhstan and a 535 kW biogas plant for poultry in Dondushany, Moldova.
