State of progress for each material

We have published final quality protocols for these waste materials:

  • Aggregates from inert waste 
  • Biodegradable waste (source-segregated) for compost
  • Biodegradable waste (source segregated) for anaerobic digestate
  • Cooking oil and rendered animal fat
  • Glass – flat
  • Lubricating oil
  • Plasterboard
  • Plastics (non-packaging)
  • Pulverised fuel ash and furnace bottom ash (bound and grout)
  • Tyres – tyre-derived rubber material

We have published draft quality protocols for these waste materials:

  • Poultry litter ash

The following materials are currently in UK public consultation:

  • Aggregates from inert waste 
  • Wood

Quality protocols for the following waste materials are currently being considered by the project:

  • Glass – CRT
  • Incinerator bottom ash
  • Paper sludge ash
  • Pulverised fuel ash and furnace bottom ash (unbound)
  • Steel slag
  • Tyres – tyre bales

The following waste materials are currently at initial stages of assessment:

None currently

The following quality protocols are being reviewed:

  • Aggregates from inert waste 
  • Biodegradable waste (source-segregated) for compost

The following materials have been assessed but end-of-waste criteria could not be established:

  • Marine-dredged materials
  • Soil – contaminated
  • Soil – uncontaminated

The following material was assessed. It was subsequently successfully proven to be a by-product rather than a waste, when new guidance was issued from Europe:

  • Blast furnace slag
