AMS and GTW Product Improvement Project

Aggregate, Masonry & Soil (AMS) and Garden & Timber Waste (GTW) Product Improvement Project

North East WRRG has identified several waste streams received at resource recovery centres (RRCs) in the region that are not being managed to maximise potential returns and to promote the creation of value-add recycled products.

Specifically, these wastes include:

  • Aggregate, masonry and soil (AMS) waste – which includes heavy waste associated with building, demolition and landscape works and includes concrete, brick, rock, stone, asphalt and soil.
  • Garden waste and timber waste (GTW) – which includes RRC garden waste and all types of timber waste.

In response, North East WRRG has appointed Reincarnate Pty Ltd (Reincarnate) and Randell Environmental Consulting Pty Ltd (REC) to investigate options for improved processes and procedures at RRCs that could:

  • Improve product quality, consistency and saleability;
  • Reduce the impacts of material contamination;
  • Increase material separation;
  • Create higher value end products through processing improvements; and
  • Unlock potential end markets for processed materials.

In general, AMS and GTW wastes are processed onsite at RRC facilities, using contracted mobile crushing / mulching / chipping infrastructure that moves from site to site as part of a processing “milk run”. In most instances this is managed council by council, except for garden waste which is currently processed through a regional contract, which is due for retendering in 2019.

The project has taken a staged approach to identifying opportunities for improvement, including:

  • A review of available data and information;
  • Site visits to nine of the 14 council owned RRCs operating in the region;
  • Analysis of the current state of AMS and GTW wastes;
  • Analysis of strengths, weaknesses, opportunities and threats for each material stream and its markets;
  • Review of current financial costs and benefits with current AMS and GTW processes;
  • Identification and documentation of recommended process improvements (including accompanying flow charts);
  • High-level analysis of financial costs and benefits associated with recommended process improvements; and
  • Workshop with local government officers to discuss improved processes for the reception, storage and processing of the materials and market option for improved materials.
