Dr. Oliver Kinnane:

There is enormous scope to use recycled materials. The point about the recycled concrete aggregate is an interesting one. I read a very interesting article recently which indicated that in Zurich approximately 45% of the concrete used in any new construction must have recycled aggregate within it and yet in Ireland we have no capacity to integrate recycled aggregate in building products. We need to move to other models. We do not need to reinvent the wheel. There is considerable evidence that the circularisation of materials can work.
