Secondary building materials
By-products of industrial processes and construction an demolition wastes, which are reused to produce new building materials.

Primary building materials
Raw materials extracted from natural sources, as well as building products made from such materials.

Recycled asphalt aggregate
Old asphalt derived by breaking up old asphalt from roads by crushing or milling.

Recycled concrete aggregate
Recycled concrete aggregate derived by breaking up large pieces of concrete by crushing and sieving.

Recycled masonry aggregate
Recycled masonry (claybrick) aggregate, derived by breaking up masonry bricks (including its mortar) by crushing and sieving.

Recycled mixed aggregate
Produced by crushing C&D waste consisting of masonry and concrete, contains at least 45% by weight of crushed concrete.

Pre-crusher fines
Fraction separated from demolition wastes by screening prior to crushing.

Crusher fines
Sand fraction separated from coarse granular material upon crushing and sieving of stony construction and demolition wastes. The grain size of this fraction generally ranges between 63 µm and 4 mm (0/4 fraction).

Old wood
Wood released at the end of its original application. Old wood is often contaminated by paint remains, adhesives and preservatives that make it more difficult to reuse.

Old plastic
Plastics released at the end of the different original applications. Old plastic is often a mix of different types of plastics, used for different purposes.
