Anaerobic DigesterOrganic food and farm waste could generate enough energy to power 2 million homes if plans by the Government are followed through.

Using anaerobic digesters, likely to be set up on farms, waste material would be converted into a rich biogas, which could then be burnt to produce energy.


In a written reply to a parlimentary question, Environment Minister, Jane Kennedy stated: "Anaerobic digestion is our preferred option for treating food waste—it has significant environmental benefits over other options for treating food waste, with the energy generated also offsetting fossil fuel power generation, and counting towards our renewable energy targets. Anaerobic digestion may be particularly cost-effective for food waste if separately collected."

Milk, Food and EnergyCountries such as Germany are already using the method with great success, and this has led Goverment officials in the UK Taking note. Anaerobic digesters not only help produce a cost effective source of renewable energy, but they also help lighten the load for Britain's vast overflowing landfill sites.

The UK's farms produce as much as 90 million tonnes of organic waste in a year, with households producing up to 20 million tonnes. If the plans are followed, 1,000 anaerobic digesters would be in place on farms across the nation by 2020.
