Concrete Recycling - TU Delft
Concrete (ca 35 €/ton, 90 €/m 3) is the largest structural material in terms of volume: EU production of ready mixed concrete is about 300 million m 3 per year. At the End-of-Life phase, concrete is mainly land filled or recycled into road-based aggregate (RBA), quite often in a mix with other mineral waste materials (bricks, tiles) from the same building.
