Besides the birds themselves, poultry farms and poultry processing facilities have one thing in common: vast amounts of organic waste material.
With energy costs rising and organic waste coming to the fore as a readily available renewable energy source, major food producers are seeing the benefit of implementing waste-to-energy solutions to reduce their dependence on the grid.
Hundreds of tonnes of chicken manure and post-processing organic ‘waste’ are produced each day – along with millions of litres of energy-rich wastewater sludge. To extract value from this mountain of waste, poultry farms typically compost their chicken litter, and chicken processors render down their organic waste to create raw materials for animal feed. But value gets lost in the process, and ‘cleaning’ the wastewater sludge can be energy- and chemical-intensive.
