Plastic material flow analysis towards a zero plastic waste economy in Australia

We’re conducting a material flow analysis of plastics across their whole life cycle to inform policy options for reducing plastic waste.

The challenge 

Plastic is a versatile and widely used material with significant benefits, including its moldability, durability, lightweight nature, and affordability. However, Australia faces a substantial plastic waste issue, generating 2.5 million tonnes annually, averaging 100 kg per person, with only 13 per cent recycled and 84 per cent ending up in landfills.

Addressing this requires comprehensive understanding of the plastic flows throughout the entire lifecycle, while designing effective plans for usage, recovery, and reuse.

Our response 

We are working in collaboration with the University of Sydney on a Plastics Material Flow Report as part of our circular economy research and CSIRO’s Ending Plastic Waste Mission.

Our goal is to explore plastic flow in different states and territories in Australia and to identify both the challenges and opportunities to support the growth of new industries and job opportunities towards a zero plastic waste economy in Australia.

By establishing a robust framework, we can systematically analyse the entire lifecycle of plastic, from production to disposal, and determine critical areas where interventions are needed.

Impact 

By identifying the main obstacles to better recycling, this research can bring about significant positive impacts:

Environmental benefits: By understanding the flow of plastic waste, we can better identify areas where waste accumulates and potential leakage points into the environment. This knowledge allows for more targeted interventions to prevent pollution and mitigate environmental harm.

Resource efficiency: Analysing the plastic flow will help optimise resource utilisation by identifying opportunities for increased recycling and recovery. This reduces the need for virgin materials and minimises the environmental footprint associated with plastic production.

Economic opportunities: Identifying bottlenecks in the recycling process can lead to the development of innovative solutions and technologies, creating new economic opportunities and growth industries focused on waste management, recycling, and resource recovery.

Policy development: Insights gained from the framework can inform evidence-based policymaking, leading to the implementation of regulations and incentives that support a circular economy approach to plastic waste management.

Community engagement: Engaging stakeholders throughout the plastic supply chain fosters collaboration and builds community awareness about the importance of recycling and waste reduction. This can lead to behaviour change and increased participation in recycling programs.
