WAP

abbr. waste acceptance procedures

Methods to be adopted for obtaining information for the safe disposal of waste at a landfill. Three levels of assessment include:

  • characterisation and properties of the waste (waste producer to supply)
  • compliance tests to ensure waste is as described (landfill operator's responsibility)
  • on site verification (landfill operator's responsibility).

WAC

abbr. waste acceptance criteria

The criteria to be met before waste is accepted at a landfill site. There are different acceptance criteria for:

  • Inert waste
  • Non-hazardous waste
  • Hazardous waste.

Each WAC may include:

  • a list of wastes not requiring a test
  • leaching limit values for contaminants
  • limit values for other parameters.

Special provisions exist for certain wastes under certain conditions.

Whole-life Costs

The whole-life cost of a facility (often referred to as through-life costs) comprises the costs of acquiring it (including consultancy, design and construction costs, and equipment), the costs of operating it, and the costs of maintaining it over its whole life through to its disposal - that is, the total ownership costs. These costs include internal resources and departmental overheads, where relevant; that also include risk allowance as required, flexibility (predicted alterations for know change in business requirements, for example), refurbishment costs, and costs relating to sustainability and health and safety aspects (Source: OGC).

Water Control Equipment

Water can be used or generated at many points during the reprocessing of aggregate such as during washing or dewatering operations. This water may need to be treated prior to release or treated and stored for future use. To this aim a range of equipment is available to control, handle and treat water used or generated during the recycling operations. This can be filters and settlement tanks, that can be used to process water retrieved from aggregate processing, or pumps and storage tanks, to store the treated water for use in further aggregate processing (in turn reducing the amount of mains water used).

Waste Transfer Note

Documentation required under the Duty of Care: all controlled waste must be accompanied by a waste transfer note when it is passed from one party to another. Notes must be kept for two years minimum and be available for inspection by the environmental regulator.
