ABSTRACT
The use of reclaimed and recycled materials in construction plays a major part in realising the goal of maximising material resource efficiency and, in turn, furthering the circular economy. The use of recycled products sits centrally within the waste hierarchy, which underpins much of the UK and European legislation in this area. Whilst steps can be taken to achieve material resource efficiency across the entire life cycle of a project, maximum sustainability benefits and use of recycled content targets on projects tend to arise throughout the early design phases, where design and sourcing and specification decisions can have more fundamental and far-reaching effects. Aggregates can be found in cement and concrete. Aggregates can be used in the formation of paths and roads or as a drainage layer.
