Australia has achieved a significant milestone with the implementation of container return schemes across all states and territories, marking a substantial development in the country's recycling efforts.

Since the introduction of the first modern container return scheme in South Australia in 1977, the participation level has expanded nationwide, leading to billions of recyclable bottles and cans being returned and a noticeable reduction in coastal plastic pollution.

The New South Wales (NSW) container return scheme, which began in December 2017, has successfully collected over 13 billion containers, resulting in approximately $1.3 billion paid out in refunds to consumers.

Moreover, about 1.1 million tonnes of material has been recycled under this program.

Leadership within the industry, such as James Dorney, chief executive of Tomra Cleanaway, has attributed the success of the NSW scheme to its provision of a dependable stream of recyclable material, which helps maintain cleanliness in recycling processes.

In Victoria, the container deposit scheme launched in November 2023 has reportedly recycled an estimated 1.8 billion containers, generating $186 million in refunds, of which more than $1.9 million has been donated to charities and community organizations.

Tasmania introduced its container return scheme in early May and quickly recorded the collection of over 1.2 million containers within its first four days of operation.

A recent study published in the journal 'Marine Pollution Bulletin' revealed a 39 percent decrease in plastic pollution density along Australia’s coastal areas over the past decade, attributing part of this improvement to the implementation of container deposit schemes.

The research indicated that, with the exception of Hobart, containers were not the primary form of debris found in coastal areas.

Hobart was reported to have the most significant presence of both whole and fragment beverage bottles, highlighting the need for effective recycling policies.

Container return programs typically require consumers to pay a 10-cent deposit when purchasing beverages, refundable upon returning the containers.

This mechanism has proven successful in creating demand for recycled materials, especially glass and aluminum, which can be endlessly recycled.

Plastic bottles, such as those made from PET, can be recycled up to ten times, maintaining high-quality standards.

Dorney noted that, in regions where these schemes are in place, return rates can exceed 70 percent, and in Norway, the return rate is above 90 percent.

He emphasized the importance of returning uncrushed containers to facilitate barcode scanning and ensuring that lids are replaced to prevent litter.

In Victoria, the container return scheme has gained immense popularity, with statistics indicating more containers returned to refund points than collected by yellow kerbside recycling bins.

The first year of the program saw one billion containers returned, with continued growth reported as public awareness increases.

Despite the advances made through these schemes, experts caution against over-reliance on recycling as a comprehensive solution to plastic pollution.

Concerns have been raised regarding the hazardous nature of plastics, regardless of their virgin or recycled state.

Professor Sarah Dunlop, head of plastics and human health at Minderoo Foundation, indicated that aging plastics break down into smaller particles, including microplastics and nanoplastics, which have been detected in various unexpected environments, including human placentas and food sources.

Dunlop's commentary on the implications of plastic degradation raises significant questions about the management of the growing quantities of plastic waste globally, highlighting the material's inherent challenges and potential health impacts.
