Waste Management

In July 2005, Derwentside Environmental Testing Services was one of the first laboratories to offer services to meet the landfill directive.  The directive's overall aim is "to prevent or reduce as far as possible negative effects on the environment, in particular the pollution of surface water, groundwater, soil and air, and on the global environment, including the greenhouse effect, as well as any resulting risk to human health, from the landfilling of waste, during the whole life-cycle of the landfill".  

The corresponding Waste Acceptance Criteria requires waste to be classified into three categories - inert waste, stable non-reactive hazardous waste & hazardous waste, prior to landfill disposal.  These tests are carried out at DETS in accordance with BS EN 12457 part 2 & 3.
