Concrete Recycling | National Concrete Pavement Technology
Demand for quality aggregates has increased as resources have decreased—so recycled concrete aggregate (RCA) increasingly offers significant savings. RCA also supports environmentally sustainable construction, lessening not only needless use of limited landfill space but also haul distances— which, in turn, cuts fuel consumption associated with aggregate acquisition and concrete slab disposal.
Carbon Footprint of Recycled Aggregate Concrete
(iii) If we consider the per capita generation average of concrete waste from the construction industry and the population of the region where most of the limestone aggregates in Mexico are produced, the recycling of concrete waste would imply that approximately 22,343 tons of CO 2-e would cease to be emitted annually in this region.
