Waste Management in the Circular Economy - image shows plastic waste in gloved hand

Tackling the global waste problem

Bringing together research expertise in geochemistry, environmental science, engineering, business and education to develop solutions for our global waste problem. Our research addresses the barriers associated with integrating wastes into the circular economy, developing and implementing cutting-edge scientific, technical, social, economic and education-based solutions.

Dirk Erler

“There is a shift around the world toward a circular economy where waste products from one process are turned into resources for another.”

Key research projects

Transforming meat residue into agricultural soil

Red meat processing in Australia is facing significant challenges including growing volumes of organic residues that are an economic and environmental liability. This ARC Linkage project led by Associate Professor Dirk Erler aims to develop a new technology that can transform the organic residues from red meat processing into engineered hydrochars. These hydrochars will be customised to store soil nutrients, improve plant growth, and actively mitigate greenhouse gas emissions.

Waste Wise Schools

Waste Wise Schools is an action-based program that encourages schools to move toward zero waste through their curriculum and operating practices. Established in 1997, the program has been implemented in hundreds of Australian schools. It has experienced tangible success in reducing schools’ waste through its approach of reduce, reuse, and recycle.

Diverting Plastics from Landfill in Red-Meat Processing

This project focuses on reducing single-use plastics waste in red meat processing. The research will provide measurable baseline data against which alternative production pathway scenarios can be assessed and evaluated to achieve sustainability goals, while maintaining or improving food safety and shelf-life standards. It contributes to achieving the Australian Meat Processor Corporation’s aspiration of the industry being recognised as global leaders in environmental stewardship and acknowledged as responsible businesses with positive economic and social impacts on their communities by 2030. The study also contributes to helping red meat processing facilities achieving the 2025 National Packaging Waste targets.
