The Adbri cement factory in Port Adelaide, Australia, has received approval from the South Australian Environment Protection Authority (EPA) for a six-week trial to burn increased amounts of plastic waste as fuel. The trial permits the factory's calciner to burn up to 32 tonnes per hour with a maximum plastic concentration of 20%, while the cement kiln may use refuse-derived fuel (RDF) at up to 10 tonnes per hour with 50% plastic concentration. However, the EPA notes that this maximum rate is not expected to be sustained continuously.

Adbri has utilized RDF since the early 2000s, claiming to have diverted at least 2.7 million tonnes of landfill waste and reduced reliance on fossil fuels. The RDF used is largely sourced from the construction sector. Due to the kiln's high temperature of 1,400 degrees Celsius, complete combustion of the RDF—including plastics, paper, cardboard, and timber—is expected.

Despite these assurances, the trial has sparked backlash from local residents and the Port Adelaide Residents Environment Protection Group. Tony Bazeley, a long-time member, highlighted concerns about the factory's proximity—just 50 metres from housing—and reported odour complaints around the site. Port Adelaide Enfield Mayor Claire Boan expressed residents' worries about potential long-term health consequences.

The local council is seeking to challenge the trial in court and is considering pursuing an injunction. They also urge the government to enact stricter regulations. Meanwhile, the EPA plans to conduct unannounced inspections during the trial and expects to release a report within 90 days of its completion. Continuous 24-hour stack monitoring will also be in place throughout the trial.

Criticism has also been directed at Adbri for its limited transparency, with some community members stating that the company provides only general information about its operations.
