Transport issues need to be addressed to take advantages of resources such as slate, says a report on the future of quarrying across north Wales (link below.)
http://news.bbc.co.uk/1/hi/wales/north_west/7245363.stmThe study identifies slate waste as a major source of "green" aggregates for the construction industry.
However, without improvements to rail infrastructure, the study warns that the full potential of slate "cannot be realised".
The document from the North Wales Regional Aggregates Working Party (NWRAWP) has been drawn up to meet demands by the Welsh Assembly Government that the industry is sustainable.
"The most efficient and sustainable means of meeting this challenge is to use rail and water transport.
"This would require either new railways, the upgrading of existing railways, or the rebuilding of former rail routes to link either the main north Wales coast railway and/or upgrade of ports such as Penrhyn (Bangor), Caernarfon, Conwy or Porthmadog."
The report from NWRAWP has now been put out for public consultation until April. Those consultations will then help form picture for the future of quarrying in north Wales until 2021.
