Report says UK must reduce landfill by using energy from waste.
GreenWise, UK. October 8, 2010.

"The Confederation of British Industry (CBI) called on the UK Government
today to encourage more waste to energy projects, as the first renewable
gas from brewery and food waste is delivered to the National Grid.

In its new report, 'Going To Waste: Making The Case For Energy From
Waste', the Confederation of British Industry (CBI) stresses the necessity
of using non-recyclable waste to meet the UK’s energy needs. It said this
is crucial for reducing the amount of rubbish being sent to landfill sites
and meeting climate change targets.

"We cannot continue dumping rubbish in landfill sites," said Neil Bentley,
CBI Director of Business Environment. "Waste that can’t be recycled could
be used to heat homes and produce electricity, as well as improving our
energy security."

This report comes out on the same day Adnams Bio Energy, in Southwold,
Norfolk, will deliver to the National Grid the first renewable gas made
from brewery and local food waste from its anaerobic digestion (AD) plant.

Earlier this week, energy company Centrica opened a plant at Didcot works
sewage in Oxfordshire, which will be the first in the UK to produce
renewable gas from human waste for household cooking and heating.

These projects utilise several of the technologies cited in the report,
including AD, where biological processes produce biogas from waste. The
report also suggests thermal treatments, such as gasification and
pyrolysis, which involve heating waste to produce gas.

The CBI also argues that non-recyclable waste should be incinerated,
saying that it is cleaner and more efficient than burning fossil fuels or
relying on landfills.

Facilities like Adnams Bio Energy will help decrease landfill use as food
and brewery waste can now be used to create energy rather than just being
dumped.

In partnership with British Gas and the National Grid, Adnams Bio Energy
will generate up to 4.8 million kilowatt hours per year, which is enough
to heat around 235 family homes. In the future, the facility will produce
enough renewable gas to power the Adnams brewery and run its fleet of
lorries, while still leaving up to 60 per cent of the output for injection
into the National Grid.

Waitrose is the first business to pledge to supply waste to the facility
and has promised to send food waste from seven Waitrose stores and one
John Lewis store.

The plant, which has cost £2.75 million to develop, consists of three
anaerobic digesters, sealed vessels in which naturally-occurring bacteria
will act without oxygen to break down up to 12,500 tonnes of organic waste
each year.

Renewable gas, produced from organic material like food waste, is very
similar to natural gas and, once upgraded to grid specification, can be
injected into the gas network for end use by customers. A study by
National Grid shows that biogas has the potential to account for at least
15 per cent of domestic gas consumption by 2020."
