Recycling construction and demolition wastes – a UK perspective

Abstract

In England and Wales, the construction industry produces 53.5 Mt of construction and demolition waste (C&D waste) annually, of which 51 percent goes to landfill, 40 percent is used for land reclamation and only 9 percent is crushed for future use or directly recovered. C&D waste may be contaminated, either through spillage from industrial processes or contact with contaminated land. There are no guidelines on how to classify C&D waste as contaminated or on risk management for contaminated C&D waste. Research at the UK Building Research Establishment and the University of Manchester has shown that new taxes are making disposal of C&D waste to landfill uneconomic, that low grade “land‐modelling” recycling is increasing, and that disposal on‐site is preferred. Sampling spatially of structures before demolition and temporally of processed C&D waste emerging from crushers is enabling sources of contamination and exceedance of guideline values to be compared with natural background levels. Improved sampling procedures and recommendations for risk assessment for the re‐use of C&D waste are being prepared.
