All options were on the table when we starting looking into how we can improve the way we manage biosolids.
Biosolids is a by-product of our wastewater treatment process. Biosolids contain Nitrogen, Phosphorous and organic Carbon. Of the 6,000 tonnes of biosolids we produce each year, about 70% is used as a soil conditioner for agricultural pasture improvement, and 30% for mine site rehabilitation.
By using different technologies we could generate
renewable energy from biosolids to reduce greenhouse gas emissions,
before using the final biosolids product as a soil conditioner. We
are investigating a range of options to help us get more benefits from reusing
