Congratulations on the report. Pity it wasnt done years ago. It needs to be the basis for a national analysis. I came across a table on the comparison which I now cannot find but made a note thus: I recall the Scottish Government suggested a remote quarry that could yield a vast amount of mineral, locally crushed and seaborne and avoiding the alarming amount of landscape damage in many parts of the UK. Norway is another possible provider. The Trent Valley exploitation must be controlled and the extensive damage modified. Demolition material should be reclaimed as an aggregate. The shelford extraction should not occur. Nice to be able to say well done County Council.
