Joint Oireachtas Committee on Agriculture and Food
Anaerobic Digestion: Discussion
2:00 am
Mr. Graeme Lochhead:
When the product is processed, it is de-odourised. There is a tone. We do not get rid of all odour, but the product is de-odourised so when the biofertiliser is put back on land, there is less odour. I will not say there is no odour because people will experience it differently.
As far as noise is concerned, we go through a noise survey within the EIA and we do a rigorous road traffic impact assessment. The Environmental Protection Agency, EPA, our EIA, the local council and the mechanisms already in place allow us to assess those issues and prove the worth, as it were.
Nephin Energy has also done a best available techniques, BAT, assessment throughout Europe. We came in 2023 - I now live in Waterford - so we are applying all the best available techniques from throughout Europe in Ireland. We are taking the lessons learned from everyone. The committee will have heard in Mr. O'Brien's opening statement that we have 300 years' experience in the team. We are not only capitalising on that. We have reached out to the wider community in anaerobic digestion, AD, to bring experience to Ireland. We are bringing the best of the best to Ireland by learning from all the things people have done. The Senator mentioned 20 years ago. There has been a lot of good and bad in 20 years and we are trying to bring all the good to Ireland.
