- 13% of homes in England had separate food waste collections, compared to 82% of households in Wales.
- A ban on food waste going to landfill would force local authorities to collect leftovers separately from households and businesses, which would be used as renewable power source.
- Such a move is also necessary because the UK will run out of new landfill sites by 2020 and the UK has to meet EU rules to stop biodegradable waste going into landfill by the end of the decade.
- Anaerobic digestion is the natural breakdown of organic materials into methane and carbon dioxide gas and fertiliser.
- Biogas is the name given to the mixture of gases formed during the anaerobic digestion of organic wastes.
- It can be used in stationary engines to generate electricity, but it is not suitable as a vehicle fuel.
The process known as anaerobic digestion could create enough biogas from green waste and purpose-grown crops to power more than 2.5 million UK homes by 2020, the study from think tank CentreForum suggested.
But barriers to increasing energy from anaerobic digestion need to be removed if the technology is to be scaled up significantly from current levels where it produces enough energy to power 300,000 homes, the report found.
The Government should ban all food leftovers from landfill by the end of the decade to boost technology which can turn it into energy, a report said today.
Councils should be given financial support to help them bring in separate food waste collections for households and businesses to ensure a steady supply of organic waste for the renewable power source.
