Aggregates are granular materials used in construction work. They include sand, gravel, crushed stone, recycled concrete, recycled asphalt, recycled brick and slags.
There is growing pressure on businesses to produce and use more sustainable aggregates by reducing their consumption of primary aggregates and switching to recycled or secondary aggregates (RSA).
If your business uses aggregates as part of its activities you should look at how you can use more RSA and less primary aggregates.
If your business produces and supplies RSA you should consider how you produce these materials, including the legislation and standards that apply.
This guide outlines how businesses in the construction industry can increase their use of RSA in building and civil engineering projects. It also covers the key issues such as waste controls, quality standards, and recovering and reusing aggregates from demolition work.
