Posted By Scott Russell During a recent audit by an external body within our organisation it was suggested by the auditor that plasterboard is now classed as controlled waste due to the Gypsum that is present in it. Can somebody confirm whether or not this is the case.

Posted By Paul Leadbetter Have they changed the terminology? I thought all non-domestic waste was controlled waste. Paul

Posted By Dave Wilson In the EWC list of waste gypsum is classed as follows 17 08 gypsum-based construction material 17 08 01* gypsum-based construction materials contaminated with dangerous substances 17 08 02 gypsum-based construction materials other than those mentioned in 17 08 01 and Any waste marked with an asterisk (*) is considered as a hazardous waste pursuant to Directive 91/689/EEC on hazardous waste, and subject to the provisions of that Directive unless Article 1(5) of that Directive applies. So its hazardous waste look at this link for more clarity!!!!! or read on Classification There are three types of entry in the List: 1 “Absolute” hazardous (these entries are colour-coded for clarity in red in WM2); 2 “Mirror” hazardous (these entries are colour-coded for clarity in blue in WM2); 3 Non-hazardous “Absolute” hazardous These wastes are marked in the List with an asterisk (*), but without a specific or general reference to “dangerous substances” in the waste description1. They are automatically considered hazardous. You do not need to work out what chemicals are in the waste to find out if it is hazardous or not. The European Commission has agreed that these wastes have one or more of the hazardous properties H1 to H14 (see Appendix A). Such entries, coloured-coded red in WM2, are called “absolute entries”, e.g., 13 07 01* fuel oil and diesel “Mirror” hazardous Some waste can be either hazardous or not, depending on whether it contains “dangerous substances” at or above certain levels. This waste is covered by linked (usually paired) entries in the List, called “mirror” entries, that are made up of: 1 a hazardous waste entry marked with an asterisk (*), and 2 an alternative linked non-hazardous waste entry (or entries) not marked with an asterisk. “Mirror” entry hazardous wastes, colour-coded blue in WM2, are identified because they refer to dangerous substances. They can do this in one of two ways: General Reference: e.g., 07 01 11* sludges from on-site effluent treatment containing dangerous substances; These wastes are classified as hazardous by looking for any dangerous substances in the waste. Specific Reference: e.g. 16 01 11* brake pads containing asbestos; http://www.environment-a...at/2_haz_waste_app_a.pdf
