Biosolids production in Australia – 2019

The total biosolids production of Australia identified in the ANZBP commissioned 2019 survey was about 371,000 tonnes per year of dry solids. This compares to 300,000 tonnes in 2010, 330,000 tonnes in 2013,  310,000 in 2015 and 327,000 in 2017.

From the data the average solids content of biosolids is around 16% and this equates to around 2.3 million tonnes of biosolids in dewatered form (also called wet).

 

Biosolids end use in Australia – 2019

Beneficial use counts for 91% of biosolids end use in Australia, a slight drop from 94% in the previous survey.

The proportion of biosolids to agricultural is now about 70%, after an upward trend from 55% in 2010 to 75% in 2017. Land rehabilitation increased in proportion this year from 11 to 16% with the change in use being from agriculture to land rehabilitation.
