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.

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.Read more
As a champion of the circular economy model in the Northern Rivers, Southern Cross is partnering with local industry to reduce waste while creating jobs and driving innovation. The ReCirculator project connects NSW Northern Rivers businesses in a circular economy ecosystem of cutting-edge technology. It acts as an economic growth driver by saving costs, improving productivity, regenerating resources and creating resilient jobs.Read more
Woodchip bioreactors reducing fertiliser pollution
To combat fertiliser pollution in waterways as a result of expanding agricultural production, Southern Cross University is working with the Coffs Harbour City Council and North Coast Local Land Services to trial new mitigation strategies. Researchers from our National Marine Science Centre have found prototype woodchip bioreactors may reduce nitrogen pollution entering nearby waterways by as much as 85% in the right conditions.Read more
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.Read more
Blueberry rust control on organic farms
Blueberry rust is caused by the fungus Thekopsora minima. The disease affects plant leaves reducing photosynthetic area and causing leaf drop, loss of vigour and reduced yield. Centre for Organics Research Plant Pathologist, Dr Jay Anderson is part of a collaborative research team working to expand the range of crop protectants available to organic blueberry growers for control of blueberry rust disease.Read more
Marine plastic research partnership
Southern Cross University is part of an international research partnership tackling marine plastic pollution. Professor Amanda Reichelt-Brushett's expertise in marine ecology and marine pollution is enhancing the partnership between Southern Cross University, the Pacific Islands Development Forum and the Federation of Indian Chambers of Commerce & Industry (FICCI).Read more
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.Read more
Professor Dirk Erler's research strives to understand the biogeochemical functioning of natural systems, and in doing so find solutions that will enable industry to advance sustainability and embed itself within the global push towards a Circular Economy. Based in the Faculty of Science and Engineering, he is currently part of a team bringing scientific expertise and academic rigour to the ReCirculator program.
Time was when the three Rs of education referred to "reading, 'riting and 'rithmetic". Today, three more Rs – reduce, reuse and recycle – are finding necessary prominence in our schools. As massive consumption creates a rising mountain of global waste, it is so important to have educators like Professor Amy Cutter-Mackenzie-Knowles and initiatives like Waste Wise Schools.
How we deal with waste is one of the most pressing environmental challenges facing the world. For Professor Andrew Rose, the principles of the circular economy are key to better waste management and resource regeneration, with the example of Southern Cross University’s ReCirculator project a brilliant example of local initiative with global reach.
Two centuries of human intervention have not been kind to the Richmond River catchment in the Northern Rivers region. In the aftermath of the 2022 Lismore floods, Professor Amanda Reichelt-Brushett began looking into the past for clues that might lead to new policies and practices to restore and sustain the catchment in the future. The result is a project with a strong community connection, one that is “re-visioning” the health of the Richmond River by seeking more informed approaches.
When it comes to protecting the environment and the ecosystems within it, plastics and polymers are often seen as the enemy. But does it have to be this way? What if plastics could be improved to such an extent as to help the environment through sustainability and adaptation? Incongruous as it may sound, it is already happening, and Southern Cross University’s Dr Lachlan Yee is one of an international cohort of researchers working towards exciting advances in polymer science.
