As of
the 16th July 2005 it will no longer be possible to dispose of gypsum
in landfills with biodegradable waste. Waste gypsum disposal to landfill
will be restricted to separately engineered containment cells within
non-hazardous landfill sites. There is currently very limited landfill
sites in England and Wales licensed to accept high sulphate bearing
waste and consequently the cost of gypsum plasterboard disposal will
rise significantly and will continue to do so.
What does this mean for the industry?
• Gypsum waste from site will need to be segregated and ideally
should be removed for recycling.
• The new regulations could create additional costs and increase
liabilities.
• Contractors may become responsible for additional waste disposal
costs.
Recommendations
• Contractual obligations covering waste disposal should be reviewed
• The company’s environmental policy should be reviewed
and reflect the new legislation
What can you do if you become responsible for gypsum waste?
There are a number of options; recycling initiatives managed by gypsum
plasterboard manufacturers and companies who will collect plasterboard
waste under a commercial agreement.
