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;
