Dual carriageway uses china clay waste

An estimated 800,000 tonnes of china clay waste is being used for the new A30 Bodmin to Indian Queens dual carriageway, the Highways Agency has confirmed.

The waste, sourced from St Austell’s china clay industry, is to be used on the carriageway, junctions and side roads in what the Agency claims is "the largest environmentally friendly road project in England."

About 90% of material for the dual carriageway’s road and asphalt layers will be waste produced by the local industry.

According to the Government’s most recent survey, about 11 million tonnes of china clay waste is potentially available as aggregate, but increasing its use means transporting the material from the south-west and overcoming related cost and logistical issues (ENDS Report 386, pp 18-19 ).
