Joint Oireachtas Committee on Agriculture, Food and the Marine

Biomethane Renewable Gas: Discussion

Mr. Declan Murray:

What must be understood is the availability of feedstock. When we talk about some 250 anaerobic digesters, we are talking about needing somewhere in the region of about 6 million tonnes of feedstock to run them. Currently, in the country, approximately 12.5 million tonnes of material suitable for anaerobic digestion are available outside the agricultural sector. The feedstock, therefore, exists today to run them. Where we see the benefit is where we can integrate with farmers and integrate with the use of the land in a way the farmers want to do it so that it helps them over time.

We would not expect all the farmers in County Roscommon, for example, to start growing silage from my plant tomorrow morning. We would certainly be in position, however, to suggest to farmers that if land is underutilised - there might be a spare 2 acres, for example - they might cut some silage and I will then buy it off them. I am not going to take all the material from their 122-acre or 160 acre-farms. This point must be understood. Throughout the country, a large amount of feedstock is currently either going to landfill or being spread on the land. As my colleagues said, it is being spread on the land purely because it can be and not because it is necessarily the right thing to do for the grass or because the nutrients are available in the right quantity. It is being done just because it can be done. I think, therefore, the opportunity is there. If we look at the way the industry in Germany has gone-----
