Waste can generally be split into two categories:
The practice of co-disposal (mixing of hazardous with non-hazardous waste) is now banned. Specific and exacting tests can be applied to assist a waste producer in defining whether or not their waste is Hazardous or Non-hazardous. This can be achieved by utilising a number of complimentary analytical techniques. The quantity of leachable hazardous components may be required.
There are several elements whose levels need to be monitored:
WAC Testing (Waste Acceptance Criteria) BSEN12457 WAC testing was introduced to supplement the revised changes to the Hazardous Waste and Landfill regulations in 2005. WAC is primarily a compliance test (PASS/FAIL) against regulatory limit values. The test involves applying an acceptance leaching test, which requires the taking of a representative sample of waste and subjecting it to leaching in water under specific test conditions. Additional tests may also be carried out e.g.; Acid Neutralisation Capacity (ANC). This test requires waste to be chemically treated by pH variation to assess stability. Leaching potential under “worst case scenario” conditions is more relevant than assessing “total” lead content with respect to assessing any risk to the surrounding aqueous environment. This is an extremely important factor when considering landfill as the preferred disposal route.
