3.3 Recycling

Action 3.3.a: (ANPAR, IGME, IGR, GeoZS, METE)

Preparation of life cycle analyses of primary & secondary aggregates

Reuse

Recycling

LCA identifies and quantifies energy and materials used, as well as releasesto theenvironment and theirpotential impacts throughout the whole life cycle

3.3 Recycling

…recycling can avoid landfill and partially displace environmental impacts of quarrying, but it is responsible of impacts related to re-processing and might increase transport-related impacts
