Valuing our environment

We always consider the potential environmental impacts when developing and maintaining our road network. We use innovative technologies and sustainable solutions to preserve our environment and historical assets.

Waste management

We are focusing the delivery of our transport operations to minimise waste, reduce consumption, and adopt resource recovery.

In 2017–18 we developed and tested processes and technologies to help us minimise our waste. We created a new TMR Waste Collection Portal to collect data and strengthened waste reporting specifications to help us to identify and address significant waste areas.

Infrastructure sustainability

We received our first formal Infrastructure Sustainability Rating from the Infrastructure Sustainability Council of Australia for the Gateway Upgrade North and Logan Enhancement projects. Our waste management initiatives, such as using more efficient pavement materials, led to an Excellent rating for these projects. The Infrastructure Sustainability Rating scheme will be rolled out across the state in the coming years, helping us to make positive environmental changes across our road network.

Crumb Rubber Modified Binder

We published a new specification in July 2017 that allows us to convert discarded tyres into bitumen seal for road pavements. This helps to reduce tyre waste, reduces cost and improves pavement performance compared to standard bitumen binders.

Road lighting replacement project

We have converted over 10% of our 30,000 street lights form the old-style sodium vapour lamps to energy-efficient LED street lights. These lights are brighter than standard lights and can save 30-70% energy.

The new lights are longer lasting and do not require specialist disposal—the previous lights contain hazardous waste and must be disposed of carefully.

Awards for excellence

RoadTek won a 2017 Premier’s Award for their submission Construction goes green—fostering a culture of sustainability and environmental awareness.

Some of the achievements and outcomes from this award include:

  • increasing the use of renewable resources such as ethanol
  • rollout of rainwater tanks across the state
  • increased use of recycled water in 1 year by 300%
  • increased recycling of waste, with 83% of waste reused or recycled
  • more efficient use of electricity per hours worked.

Award for Environmental Excellence

The International Erosion Control Association Australasia awarded us the prestigious Annual Environmental Excellence Award. We received the award in recognition for best practice in erosion and sediment control on the Bruce Highway Cooroy to Curra (Section C: Traveston to Woondum) project.
