Poultry litter generates new income for farmer

Written by: Recycling Waste World | Published:

Hereford-based Great Ynys Farm will use poultry power to generate a new income stream as a renewable energy generator.

The farm, which has 125 acres of arable land and a 90,000 broiler chicken operation, will use anaerobic digestion (AD) to convert chicken litter into biogas for renewable electricity and heat generation.

The green electricity will power the poultry houses and AD system, with a 90% surplus sold to the National Grid, while the captured waste heat will provide warmth for the chicken houses thereby displacing fuel oil and propane gas. Generation is scheduled to begin on 1 August 2011.

The AD system will have capacity to process 700 tonnes of poultry litter and 1000 tonnes of cattle slurry, mixed with 3000 tonnes of maize silage per annum.

The farm’s combined heat and power system will provide 250kW of electricity, sufficient to power 450 homes, and 200kW of heat. This will qualify for financial payments from the government’s feed in tariff and renewable heat incentive programmes – providing 14 pence per kW on all electricity generated and 6.5 pence per kW for the captured heat that is used on site.
