University of South Australia PhD student Gabriela Dias Guimaraes is developing a computer framework that helps designers, architects and engineers take waste into consideration at every step of construction projects.
Victoria’s reliance on extractive resources is increasingly becoming an unviable prospect, but a new solution will soon see more construction and demolition materials recovered in the state.
The Queensland Government has released its 2018 State of the Environment report, highlighting interstate waste as a pressure on the state’s landfills.
Relatively low costs of landfill disposal in Queensland are said to be the motivator for cross-border flow of waste in the report.

More than 1.26 million tonnes of domestic waste, 2.146 million tonnes of construction and demolition waste (C&D), and 1.443 million tonnes of commercial and industrial (C&I) waste was sent to landfill in 2016-17.
Of this, 53,000 tonnes of domestic waste, 640,000 tonnes of C&D waste and 23,000 tonnes of C&I waste was generated interstate and transported to Queensland landfills.
The amount of trackable waste received from interstate also increased from around 13,000 tonnes in 2011-12 to 52,200 tonnes in 2015-16.
Littering and illegal dumping is also highlighted as a serious environmental pressure, with reports suggesting the problem as widespread throughout Queensland.
The average number of litter items was found to be higher in Queensland than other Australian stats, particularly at beaches, retail strips and recreational areas.
Queensland Environment Minister Leeanne Enoch said the increase in the amount of interstate waste was proof that that Queensland needed a waste levy.
“The state government’s waste management strategy will stop interstate waste and increase investment in the industry to encourage more recycling and create jobs,” Ms Enoch said.
