The Impact of Waste
Waste has become one of the most pressing environmental challenges of the 21st century. Globally, we generate over 2 billion tonnes of municipal solid waste annually, with projections showing this could increase by 70% by 2050. Only about 13.5% of this waste is recycled while 33% is mismanaged through open dumping or burning. The remaining waste predominantly ends up in landfills,
Global Challenge
Electronic waste represents the fastest-growing waste stream, increasing by 21% in just five years, with only 17.4% being properly recycled. Meanwhile, plastic production has reached 400 million tonnes annually, with 8 million tonnes entering our oceans each year, forming massive garbage patches and breaking down into microplastics that have now been detected in human blood, placenta, and lung tissue.
Australia's Waste Crisis
Australia faces unique waste management challenges as one of the highest waste producers per capita in the world, generating approximately 2.7 tonnes per person annually. Despite our relatively small population, Australians discard:
- 67 million tonnes of waste each year
- 130,000 tonnes of plastic that enters waterways and oceans
- 7.3 million tonnes of food waste annually, worth $36.6 billion
- Over 800,000 tonnes of e-waste, growing three times faster than general municipal waste
Environmental Consequences
The environmental impact of our waste extends far beyond visible litter:
Climate Change
Landfills account for 3% of Australia's greenhouse gas emissions through methane release.Waste
decomposition in landfills generated 11.9 million tonnes of CO₂ equivalent in 2020. Additionally, the extraction and processing of virgin materials to replace discarded resources contributes significantly to carbon emissions.

Ecosystem Destruction
Waste leachate—the liquid that drains from landfills—contains heavy metals, organic compounds,
and pathogens that contaminate soil and groundwater.
Research has identified over 400 landfill sites across Australia at risk of contaminating groundwater resources. Australia's unique marine ecosystems are particularly vulnerable to waste impacts. The Great Barrier Reef and other marine environments face threats from plastic pollution, with 71% of seabirds in Australian waters having ingested plastic. Studies of remote beaches in Northern Australia have found up to 3,000 pieces of debris per kilometer.

Resource Depletion
Our linear "take-make-dispose" economy perpetuates the extraction of finite resources.
Australia exports significant raw materials that could be sourced from recycled content. For example, mining one tonne of gold requires processing 200,000 tonnes of ore, while the same amount could be recovered from just 41 tonnes of mobile phones.

The Path Forward
The waste crisis demands a fundamental shift toward circular economy models. By keeping materials in use and regenerating natural systems, we can decouple economic growth from resource consumption. The Australian government has set targets to:
- Reduce total waste generated per person by 10% by 2030
- Achieve an 80% average resource recovery rate from all waste streams by 2030
- Significantly increase the use of recycled content by governments and industry
At Cirqula, we’re actively developing solutions across key waste streams to address these challenges. Our sector-specific recycling innovations demonstrate that economic opportunity and environmental stewardship can advance together, creating a sustainable pathway for waste management in Australia and contributing to global solutions.
