Australian Minister for the Environment and Heritage, Dr David Kemp has launched a voluntary product stewardship commitment by the Vinyl Council of Australia to improve environmental performance in the polyvinyl chloride (PVC) industry. The commitment will promote more environmentally friendly practices in the production, use and disposal of PVC products and chemicals used in their manufacture by moving to phase out cadmium and lead based stabilisers, and establishing a program to recycle pipe off-cuts.
The commitment also addresses the use of phthalate plasticisers; waste management; research and public reporting, with a technical steering group representing industry, Commonwealth and science to inform industry of emerging and relevant environmental issues. The PVC industry is an important contributor to Australia’s economy, with A$800 million worth of PVC products sold in Australia each year. PVC is used for a wide range of materials from the pipes used to deliver clean drinking water to 99 per cent of Australian homes, to cordial bottles.
However, there are potential environmental and health concerns in the production of PVC resin, and products and in their end-of-life disposal. Vinyl chloride monomer – the raw material from which the resin is made – can be hazardous to human health and the environment if improperly handled. The use of cadmium and lead in PVC additives – though small by comparison with other uses of these metals – needs to be minimised in order to help reduce their load on the environment. The industry has already moved to address environmental issues involved in the processing of PVC, voluntarily removing the use of lead stabilisers in the manufacture of potable water pipe, and participating in a recycling program to grind PVC bottles into powder and made into flooring tiles and pipe fittings.
Current levels of PVC recycling are low, largely because 80 per cent of products last between 15 and 100 years, but recycling opportunities need to be explored as PVC products reach the end of their useful life. The commitment will have an initial life of five years and will be reviewed annually. More specific targets will be established as environmental issues and mechanisms to address them are identified.

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
