Recycled and secondary aggregates are making an increasingly important contribution to the UK's needs..
By reducing demand on primary aggregates, they are helping the industry to become more sustainable - in other words, not using up assets today that our children may need tomorrow
The UK utilises 70 mt of recycled and secondary materials in the GB aggregates market, this contributes 28% market share which is three times higher than the European average, highlighting the fact that the use of recycled and secondary materials in Britain is close to full potential.
Construction will often require demolition of existing buildings and structures built with hard and durable materials such as concrete and brick which can be recycled and re-used in new construction.
Recycled aggregates are the product of processing inert construction and demolition waste, asphalt planings and used railway ballasts into construction aggregates. Just as primary aggregates, these materials conform to European aggregate standards and national specifications, and make a key contribution to total aggregates demand.
Construction activity can also require excavation work such as groundworks and tunnelling which generate softer materials including soils, sub-soils and clays which can be used for quarry restoration.
Secondary materials are derived from other industrial processes including:
Collectively, these materials contribute significantly to the total aggregates demand across the whole UK Market.
The challenges that go with recycled and secondary aggregates are threefold:

WRAP Guidance on the Quality Protocol requirements for the production of aggregates from inert waste:
The Environment Agency is currently reviewing the WRAP protocol for the production of aggregates from inert waste and MPA are at the forefront as the industry voice on recycled and secondary materials for aggregate production.
The Mineral Products Association (MPA) is the trade association for the aggregates, asphalt, cement, concrete, dimension stone, lime, mortar and silica sand industries.
