Mr. Noel Gavigan:

It depends on how a biogas plant is defined but, operationally, there are in and around 15 of what we would consider a traditional type of biogas plant. They can be arranged in different ways and there are many sewage treatment plants, which would add another 20 or 30 plants. In Germany they are approaching 10,000 plants. It is a considerable and large industry there. The UK is second and Denmark is third in terms of numbers. There are approximately 4,000 in the UK and approximately 3,000 in Denmark.
