Description
of the CWTC
Waste
Profile Analysis
To determine
the appropriate treatment method, a sample from each batch
of chemical waste is characterised by chemical analysis. The
waste profile characterisation falls into a range of categories
such as acids, alkalis, spent etchants (ammoniacal), spent
etchants (non-ammoniacal), toxic metals and other metallic
solutions, halogenated and no-halogenated and flammable solvents,
waste oil and others (cyanide, pesticide, PCB containing wastes
etc.). Waste oil is mainly MARPOL (MARine POLlutants) Annex
I waste, which arises from ships using Hong Kong's port facilities.
Each category of waste, is appropriately treated at the CWTC.
