Put simply, a WAC test tells you which landfill site you’re allowed to send your waste to.
There are two tests to carry out. The first, the Waste Classification Test, classifies the kind of waste you’re looking at. Then you send the waste to undergo a WAC Test. Together the two tests give you all the information needed by a landfill operator. Every time you have waste to dispose of in landfill, you’ll need to test it first.
Waste Acceptance Criteria testing is done once your waste has been pre-characterised as hazardous via a Waste Classification Test. WAC testing is also used when non-hazardous waste is considered to be inert, to check whether it might be possible to dispose of it in an inert landfill site. As the producer of the waste, it’s your legal duty of care to carry out the characterisation and see if it’s hazardous or not. We carry out the WAC testing side of things.
