Recycled Aggregates from Inert Waste
Annex 2 details the main standards and specifications relating to aggregates. The majority of recycled aggregate in Scotland is either capping material (e.g. 6F4 and 6F5) or subbase (e.g. Type 1). Some production sites can produce aggregates for concrete, such as washed sand, but this is less widespread. The WRAP specifier tool has details of

Q&A: Basics of recycled concrete
Recycled aggregate is waste material from demolished buildings or bridges, for example. When demolishing such structures, the waste needs to be sorted into wood, glass, etc. and concrete. This is called selective demolition, as the structure isn’t knocked down as a whole, but the materials are taken down selectively.

Why & How to Use Recycled Crushed Concrete
The first step to recycling old concrete is to use industrial crushing equipment in order to break up the original structure. Next, the broken up concrete is run through a secondary impactor. After being crushed to an even smaller size, the crushed concrete is then screened so that dirt and other foreign objects can be removed. After this step, the concrete is separated out by size.
