The next 5-10 years?

It is an important addition to general capability for energy production.

Anaerobic digestion is an organic treatment, a treatment of organic waste.

Little bugs munch the organic material and produce a gas which is about 60% natural gas.

As a result, we can take the gas and turn it into electricity or clean it by removing the carbon dioxide and other gases and put the natural gas into the gas grid.

Is it going to be individual houses having this?

How much percentage can they produce?

I would guess that we can produce about 2% of our electricity from anaerobic digestion.

It is widespread in germany but there, they have been in the smaller plants using maize or other crops which they have grown for the purpose.

There are some of those plants in the u.k. but our focus is on using waste, particularly food waste and so we are doing a number of good things.

We are dealing with waste which might otherwise go into landfills.

We are producing renewable energy.

What is left is a natural fertilizer which can go back on the land.

These plants, are they small enough to have next to a semi detached house or does it have to be elsewhere and then dished out?

The ones that we are doing our on an industrial scale.

Producing about 2.5 megawatts on average per ton.

That is around enough for 5000 houses.

They are on small-town scale in the u.k. ultimately we would like to produce smaller ones which could be used internationally may be in development come -- countries where they can do a good job for local communities.
