The project aim is to introduce the first optically readable sequence-defined polymers based on fluorophore excimers, whose information content can be read as simply as conventional barcodes. These macromolecular barcodes, embedded in solid polymer matrices, will overcome the current limitations of reading information from synthetic macromolecules. An interdisciplinary effort will fuse chemistry, law, and criminology to develop the technology in ways that are expected to address illicit plastic waste trafficking – ending the anonymity of polymer waste by creating a regulatory and criminological paradigm for tracing plastic waste to hold actors in the value chain responsible.Read moreRead less

This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise breakdown of mixed polyolefin plastics into monomers for the subsequent manufacturing of virgin plastics in a circular economy, and to elucidate fundamental underpinning reaction mechanisms. Outcomes will stimulate the Australian waste plastic recycling industry, and minimise plastic accumulation in the environment.Read moreRead less
