Inert Waste

The Landfill (England and Wales) Regulations 2002 and the Waste Management Licensing Amendment (Scotland) Regulations 2003 provide the following definition of inert waste: "Waste is considered inert if:

  1. It does not undergo any significant physical, chemical or biological transformations;
  2. It does not dissolve, burn or otherwise physically or chemically react, biodegrade or adversely affect other matter with which it comes into contact in a way likely to give rise to environmental pollution or harm to human health; and
  3. Its total leachability and pollutant content and the ecotoxicity of its leachate are insignificant and, in particular, do not endanger the quality of any surface water or groundwater."
