The Western Australian Waste Authority's two annual surveys, the 2015-16 Census of Local Government Waste and Recycling Services and the Recycling Activity in Western Australia 2015-16 reports, show that recycling rates are increasing in the State's commercial and construction sectors, but have fallen in the municipal waste sector.
Waste recycling in the commercial and industrial sector was 56 per cent in 2015-16 - exceeding the State's 2015 target of 55 per cent.
In the construction and demolition sector, the recycling rate improved by 15 percentage points to 57 per cent in 2015-16 compared to the previous year.
In the municipal waste sector, however, recycling fell to 36 per cent in the Perth metropolitan region in 2015-16, well below the State's target of 50 per cent.
The Census confirmed that three-bin systems - including those in the State Government's Better Bins program - outperformed two-bin kerbside collection systems.
The Census also showed that local governments in Western Australia spent $288 million collecting 1.5 million tonnes of domestic waste in 2015-16, with an average of 28 kilograms of waste generated per household each week.
