IN AUSTRALIA
WITH NEXT GENERATION ASPHALT RECYCLING PRACTICE
Sustainability
resource recovery
Stanley Roads are leading the way in Australia with “Next Generation Asphalt Technologies” to improve roads, change industry behaviour and develop next generation pavement recycling practice. The development of the resource recovery and recycling plant will provide the latest innovation to Queensland’s waste management industry, a significant reduction of waste stockpiles at landfills, recycling in commercial practice, job development opportunities and substantial environmental benefits in reduced natural resource extract, waste reduction and energy consumption.
Key benefits of Stanley Roads Resource Recovery plant:
Percentage of materials recycled and reused is close to 100%
- Less waste
“Recycling and Waste in Queensland 2018” showed 5,300,000 tonnes of waste being generated from C&D which includes road pavement, representing a 20% growth from 2016/17.
49.1% of this waste is disposed with 95% of this disposed waste ending up in landfill, 91% of which in SE Queensland. Equates to 2,600,000 tonnes annually.
Reduction on need to use virgin quarry materials
– Less strain on natural resources
In 2018, Queensland produced 40,721,966 tonnes of hardrock quarry material of this 15,734,829 tonnes was used for virgin road base or subbase.
Reduction in volume of trucks travelling empty
– greater utilisation and reduction in carbon footprint
The carbon dioxide emitted by trucking, (1.5kg of CO2 per tonne of product) increases the embodied emissions of the delivered product significantly, such that at 10km the embedded carbon dioxide per tonne is four times greater, and at 100km it is more than 30 times. (West, 2011)
Wet processing equipment
- means lower dust generated, better for the environment
The crushers and screen decks are fitted with a Dust Suppression System which utilises Sprays bars with atomiser nozzles mounted over crusher mouth, product conveyor feed & discharge points to minimise the production and dispersion of dust during the crushing and separating process involved in the resource recovery process.
