Recycling hampered by product quality


EFFORTS TO increase the use of recycled and secondary aggregates in the construction industry will stall if suppliers do not improve the quality of their products, contractors warned this week.

The warning followed publication of government funded research that urged the aggregates industry to up the use of recycled materials in construction.

An investigation by WRAP (the Waste and Resources Action Programme) found that while the use of recycled materials is increasing by around 2.5Mt every year, only a quarter of the 275Mt of aggregates used each year are recycled.

Yet based on current consumption levels the agency predicts that the UK will need an additional 20Mt of aggregates per year by 2012.

Contractor Costain said that it could use up to 75% more recycled aggregates on roads projects if suppliers had invested in technology such as soil washing.

'Suppliers are quite happy to get demolition rubble and crush it to make products like capping, but with a little more processing they could make something of higher quality that they could sell for more, like asphalt or concrete mix, ' said Costain major civil engineering senior agent Paul Boulton.
