Reusing biosolids is one of the ways we’re responding to the impacts of climate change in Western Australia.

Biosolids are the organic sludge from domestic and industrial wastewater, that has undergone significant treatment to make it safe to use as natural fertilisers and soil improvers. In WA, we use biosolids to grow broad-acre crops such as wheat, oat, canola, lupins and with additional processing, for compost.

Unlike synthetic mineral fertilisers that can leach excess nutrients into waterways, organic biosolids bind quickly to soil particles with nutrients slowly mineralising for plant growth over a longer period.

Please refer to the attached biosolids fact sheet for further information.
