Working with the Water Industry to Recycle Biosolids

Finding better ways to manage and re-purpose polluting biosolids, sewage sludge from wastewater, is a pressing issue for the water industry. Current management processes are labour intensive, take up large amounts of land and risk polluting adjacent land and water tables.

RMIT partnered with South East Water and Intelligent Water Networks to tackle this problem. The partners designed, constructed and commissioned a pilot PYROCO processing plant capable of converting 75kg/hr of biosolids into value-added smart carbon materials (biochar). RMIT’s interdisciplinary team of engineers, scientists, social scientists and economists assisted in trialling the social and commercial viability of this disruptive conversion technology.

This partnership has the potential to yield far-reaching social, environmental and economic benefits, including cutting the energy needed to manage biosolids by up to 85 per cent; reducing capital and operating costs by up to 40 per cent, and reducing overall biosolids management costs by over 30 per cent. 

This project was initially funded by RMIT’s Platform Opportunity Fund and our project partners, and led from the School of Engineering.
