New research demonstrates benefits of RSA

PROOF of the benefits of using recycled and secondary aggregates (RSAs) is now freely available as a result of the Aggregates Research Programme jointly run by the DTI and WRAP.

Established three years ago, the research programme was set up to identify and address barriers to the specification and application of RSAs with the aim of expanding the market for these materials.

According to WRAP, the need to increase the use of RSAs is highlighted by figures which show that, in the UK today, around 275 million tonnes of aggregates are used each year as raw construction materials. Currently only 65 million tonnes (around 23%) of this total is derived from recycled or secondary sources.

 

While the UK leads the rest of Europe in this regard, the aggregates sector needs to increase the use of RSAs significantly if it is to continue to meet demand and remain competitive, says WRAP. All indications are that the UK will need an additional 20 million tonnes of aggregates per year by 2012.

Results of the last three years research projects can be obtained, free of charge, from the publications section of the new AggRegain web site: www.aggregain.org.uk

In April 2005, responsibility for the continuation of RSA research passed entirely to WRAP as an integral part of its Aggregates Programme. The latest research, which has just been launched, builds on the previous work and focuses on projects that address either a significant waste stream or a significant technical barrier to RSA use.

The latest projects will last between nine and 21 months and will add to the information already contained within the AggRegain web site to help those looking to produce, specify or use RSAs.
