The potential for using landfill gas to heat commercial glasshouses has been successfully demonstrated in a small-scale project at Bilham Grange Farm, Brodsworth, near Doncaster in the UK. The system, including the glasshouse, cost 33,000 pounds to install and it is anticipated that this investment will rapidly be recouped from the profit accruing from sales of both glasshouse crops and crops grown on the restored landfill area. A five-pipeline buried gas abstraction system was constructed through the landfill site and the gas was directed to the heating system of a small commercial glasshouse. Both glasshouse and heating system had been purchased specifically for the purpose. The equipment has operated with few problems and a very high level of reliability, and there is no evidence of higher maintenance costs being incurred, or of more rapid equipment deterioration than would occur with the firing of more conventional fuels.
