Features of CWTC
Introduction
Chemical waste in Hong Kong is disposed of either on-site
where the chemical waste is generated, at the landfill site
or at other off-site disposal facilities including the Chemical
Waste Treatment Centre (CWTC). All these facilities must be
licensed by this department. Some chemical wastes such as
precious metal sludges are exported to overseas countries
for recycling.
The CWTC
has been in operation since 1993. The design capacity of the
CWTC is 100,000 tonnes per year of chemical waste. The management
and operation of the centre is contracted to Enviropace Ltd.
The main
activities of the CWTC are Chemical
Waste Collection, Waste
Profile Analysis and Chemical
Waste Treatment. The three main treatment processes are
Oil/Water Separation, Physical/Chemical
Treatment and Incineration.
The CWTC includes several Ancillary
Systems designed to support the treatment processes, these
are the Waste Container Handling, Storage Tank Farm, Laboratory
and Computer System. The intake
of chemical waste collected by composition and distribution
according to industry are regularly reported.
The various
activities of the CWTC are closely monitored which include
the air emissions, the
stabilised residues
and the wastewater discharges
to ensure that operations are environmentally safe and sound
and meet the environmental statutory requirements. Regular
Environmental Performance
Reports of the CWTC consisting of effluent, stabilised
residue and stack-gas emission data are produced. The levels
of dioxins, measured in the ambient
air and at the incinerator stack, are routinely monitored
and reported. Moreover a Preventative
Maintenance Programme and Emergency Response Plan are
in use.
The Government
will recover up to 100% progressively the
fee/charge of treatment in the future.
