Recycled aggregates (RAs) have been playing an important role in replacing natural aggregates (NAs) in concrete production, thereby contributing to a reduction in the extraction of natural resources A number of standards exist to regulate the use of recycled aggregates in concrete, such as EN 12620 (2008) and EN 206 (2016).

The Contribution of Recycled and Secondary Materials
to these two reports, the total production of recycled aggregates in England reached 42.07 million tonnes in 2005 and 43.52 million tonnes in 2008. These tonnages include ‘hard inert’ CDEW, including only materials which would generally be suitable for processing into aggregates.
