All indications are that the UK will need an extra 20 million tonnes of aggregates per year by 2012, with companies being encouraged to use higher quality and higher value Recycled Secondary Aggregates (RSAs).
New research findings from the Aggregate Research Programme (ARP) suggest that while the UK leads the rest of Europe in using RSAs, the sector needs to increase the use of these significantly if it is to continue to meet demand and remain competitive.
This has been illustrated by the fact that of the 275 million tonnes of aggregates used in the UK today as raw construction materials, only 23% are from secondary sources.
After responsibility for recycled and secondary aggregates research passed to WRAP in April this year as part of its Aggregates Programme, the latest findings build on those of the previous research work.
The focus is on projects that address either a significant waste stream or a significant technical barrier to RSA use. These include projects designed to investigate the potential for increased use of RSAs in hydraulically bound materials and concrete, and the role of RSA use in relation to the reduction of C02 emissions.
