Wastes of industrial non-renewable origin (solids or liquids) combusted directly for the production of electricity and/or heat. It is measured on the basis of the heat content (net calorific value) of wastes used as fuel. Renewable industrial waste should be reported in the Solid biomass, Biogas and/or Liquid biofuels categories.
