Environmental Impacts of Recycled Plastic Concrete

The reuse of fresh, returned plastic concrete offers the opportunity to directly reuse the water, cement, and aggregate used in the production of concrete. The impacts due to manufacturing and transportation of additional admixture to stabilize recycled concrete are offset by the avoided impacts of concrete disposal, and pale in comparison to the impact reduction from the displacement of virgin concrete

ENVIRONMENTAL IMPACT OF CONCRETE RECYCLING,

The processes of quarrying, crushing, and grinding of natural aggregates produces a greater environmental burden than the processes of crushing and recycling of concrete, especially concerning CO2. This is probably due to the fact that, in all processes of producing natural aggregates, the extraction processes must also be considered, with the consumption of energy implicit in these.
