Researchers in Australia are developing methods to convert common organic waste, including biosolids from wastewater treatment and household garden debris, into biochar, a charcoal-like substance that could serve as a component for more cost-effective and safer sodium-ion batteries.
The collaborative project involves RMIT University, Deakin University, and Barwon Water. While biochar is traditionally used to improve soil quality, the research team is exploring its potential as an anode material for sodium-ion batteries.
Sodium-ion batteries, which are already considered cheaper alternatives to lithium-ion technology, could become even more affordable if biochar proves suitable for enhancing performance.
“Biochar is looking promising as a next-generation battery material, and through this project we’ll continue to explore what biochar composition will enhance battery performance,” said Associate Professor Nolene Byrne of Deakin University.
The initiative is part of Barwon Water’s broader effort to establish a circular economy in the Geelong region. The program aims to convert roughly 60,000 tonnes of biosolids and other organic waste into sustainable products annually. The project is supported by a $50 million grant from the Australian Government’s Trailblazer Universities Program.
