An Australian first, waste-to-energy process that converts biosolids into a safe, environmentally friendly biochar, providing a sustainable solution for the waste product.

Biosolids gasification transforms wastewater treatment residuals into a renewable heat source and a clean, stable biochar product.

The treatment process combines traditional technologies of dewatering, drying and gasification and integrates them via a heat recovery loop whereby operation of the drying stage is largely energy neutral.

Biochar is a carbon-rich, stabilised material and the carbonised product of biosolids that have undergone gasification via thermal treatment in an oxygen-limited, high-temperature environment

More water authorities are rethinking their biosolids disposal and adopting gasification technology to:

• Avoid ongoing transport and landfill costs.
• Achieve PFAS and microplastics destruction.
• Meet ambitious net zero and circular economy goals.
