Abstract: This paper explains how to manage the waste generated by a group of concrete plants. These plants are located within a radius of 1000 metres in an environmentally protected area, which is situated on the outskirts of Oviedo (Spain).

These concrete plants produce around 45000 tons of waste every year. This waste comes from the specimens used in the test for quality control of manufactured products. It is also obtained after washing trucks mixers and from concrete returned to the plant because it does not meet the requirements.

Until 2001 the waste was stored in a common accumulation area for all concrete plants.
The waste was left here a considerable time before being moved to a landfill. The transport and reception of wastes generated high costs. In 2001, when the First National Plan for Waste came into effect in Spain, the common accumulation areas were forbidden.

Concrete plants decided to join forces and set up a recycling plant for construction waste. It is located near the area. The products obtained are used as recycled aggregates for manufacturing backfill concrete, non-structural precast concrete and structural concrete.
