Researchers at the University of Queensland have developed innovative bio packaging from sugarcane waste, which not only extends the shelf life of produce but also possesses antimicrobial properties that can eliminate viruses and bacteria, including COVID-19 and influenza A, within 30 minutes.

This new technology aims to address two significant issues: plastic packaging waste and agricultural food waste, which together contribute to an alarming 1.4 billion tonnes of waste annually.

Dr. Nasim Amiralian, who leads the project, emphasizes that this technology could significantly help Australia tackle its high levels of single-use plastic waste, which ranks second globally per capita.

The bio packaging offers numerous benefits, including reduced waste and emissions, the use of recyclable green solvents, enhanced biodegradability, and the prevention of microplastic generation.

In addition to the packaging, the research team is also developing specialized coatings for avocados and bananas to slow their ripening process, further reducing food waste during exports.

This research is conducted in collaboration with Sunshine Sugar, a company dedicated to finding alternative uses for the 85% of sugarcane that is not processed into sugar.

Sunshine Sugar is already converting some of its waste into boiler fuel and is exploring additional revenue streams to diversify its operations.

Supermarket chains like Coles, ALDI, and Woolworths are actively working to reduce plastic waste through various initiatives, including the introduction of recyclable paper bags and significant reductions in plastic usage.

These efforts align with government regulations and the broader trend towards more sustainable practices in the agricultural industry.

In a related development, Wagner Sustainable Fuels, in partnership with Boeing and the Queensland government, has announced plans for a renewable fuels refinery in Brisbane, which aims to produce sustainable aviation fuel and renewable diesel by 2026.

The researchers anticipate that the bio packaging could be commercially available within four years, contingent on industry support, marking a significant step forward in sustainable packaging solutions.
