Recycling project paves a new way

Friday, 25 February 2022

Plastic bags and tyres that were destined for landfill are among the materials that have been recycled to reconstruct a road in Geelong’s south.

The City is trialling the use of recycled fine crushed rock (FCR), Polyrock aggregate kerb mix and crumbed rubber asphalt in the rebuild of Maple Place, Waurn Ponds.

Existing materials from the road – including 40 tonnes of asphalt, 163m³ of FCR and 277m of concrete kerb – were recycled locally.

The material was crushed and sorted, ready for reuse in this and other road projects in Greater Geelong.

A total of 366 tonnes of recycled FCR was used in the road sub-grade and sub-base layer, while kerb and channel works were undertaken using polyrock aggregate.

Polyrock is a sustainable recycled plastic aggregate alternative, that is made up of 95 per cent post-consumer plastic waste.

The Maple Place project is part of the City’s clever and creative ‘Recycled Roads’ program, which incorporates a variety of materials collected via kerbside recycling.

Through various trials, roads have been built using crushed glass as a replacement for sand, and PlastiPhalt, which incorporates plastics destined for landfill.

Deputy Mayor Trent Sullivan said these projects were finding a new use for tonnes of glass and plastics.

The roads program is a great example of our innovative work in keeping materials from landfill and reducing our carbon footprint. Through a highly efficient construction process, the Maple Road works are also cutting carbon emissions by up to 30 percent. These trials allow us to assess the benefits of new sustainable products and methods, ahead of their adoption into regular practice.

The waste-reducing road projects were recently honoured with a 2021 Keep Victoria Beautiful Sustainable Cities Award. 

The City claimed a total of four awards at the statewide event, including the overall Keep Victoria Beautiful Sustainable City Award. 

Cr Belinda Moloney, Chair of the Circular Economy portfolio said the projects highlighted the Council’s commitment to adopt better technology options, support local innovation and deliver better environmental results through the Sustainability Framework and Action Plan.

We are committed to creating sustainable practices across the organisation that help us meet our goal of being a zero-emission, climate ready city. The energy-saving and waste-reducing road projects will help deliver the best outcomes for people, the environment and the economy.

Council’s Climate Change Response Plan sets a target are for all City-managed operations to reach net zero emissions by 2025, and for the municipality to reach net zero community emissions by 2035.

The benefits of the Maple Place, Waurn Ponds project:

  • Recycled 40 tonnes of asphalt
  • Diverted 50 tyres from landfill
  • Re-used 366 tonnes of fine crushed rock
  • Diverted about 3000 plastic bottles from landfill
  • Diverted about 150,000 plastic bags from landfill
