The NSW Environment Protection Authority (EPA) has reported that considerable progress has been made in the New South Wales recycling sector, with the state now capable of processing nearly 140,000 tonnes of additional material annually.

Critical to this triumph has been $9.1 million in funding from the EPA over the last five years under the Product Improvement Program. The program was set up in response to China’s 2018 National Sword Policy, which restricted the importation of certain materials for recycling, including most plastics, paper and cardboard, glass and other solid wastes.

The program’s successful completion coincided with National Recycling Week.

The initiative has achieved:

  • Almost 85,000 tonnes of recyclable material re-directed from landfill.
  • Contamination rates for plastic, and paper and cardboard dropping up to 11%.
  • Over 46,000 tonnes of recycled material processed or reprocessed per year.
  • More than 24,000 tonnes of plastic reprocessed and remanufactured.
  • More than 46,000 tonnes of recycled material used to manufacture new products per year.
     

NSW EPA CEO Tony Chappel said increasing the state’s capacity to recycle material is critical, given landfill space in Greater Sydney set to be exhausted by 2030.

“At our recent Circular Economy Summit, we highlighted the need to take decisive action and come up with new waste and recycling solutions,” he said.

“This program showcases what we can do when we invest and innovate together. We’ve seen significant leaps forward by industry at all stages of the recycling journey from sorting to reprocessing and remanufacturing.

“Material recovery facilities have improved the quality of recycled products, contamination rates have dropped up to 11%, and we’ve increased our capacity to process waste by almost 140,000 tonnes each year.

“This is a huge achievement, equivalent to 1700 Olympic swimming pools.”

China used to be the largest importer of recyclable products — accounting for 30% of Australia’s exports. The National Sword Policy restrictions had a huge impact on Australia’s ability to export recyclable materials, requiring the recycling sector to shift towards local solutions.

In 2018–2019, 22 grants were awarded to help industry to expand and improve local recycling markets and infrastructure.

The funding propelled a diverse range of projects whose goals included enhancing recycling infrastructure; driving innovation for recycling plastics, paper, cardboard, glass and problem waste; and providing more Australian-sourced recycled material for use in product manufacturing.

These results helped NSW target 53% of materials impacted by the National Sword Policy in NSW.

Battery life and EV cybersecurity projects receive funding

Battery life and EV cybersecurity projects receive funding

Swinburne University of Technology researchers have been awarded close to $920,000 to advance two projects for battery life and EV cybersecurity, securing a portion of over $46 million shared across 75 new projects.

The university received the funding in the latest round of Australian Research Council’s (ARC) Linkage Projects 2024. The scheme, part of the ARC’s National Competitive Grants Program, funds research that delivers practical benefits and strengthens Australia’s innovation and industry capabilities.

Swinburne’s Deputy Vice Chancellor Research, Professor Karen Hapgood, said, “These projects demonstrate how our researchers are partnering with industry to deliver practical solutions, from extending the life of battery systems to securing Australia’s electric vehicle infrastructure. It’s a powerful example of how university research is driving innovation and supporting a more sustainable, technologically advanced future.”

The first of the two projects, led by Professor Weixiang Shen, received $449,882 to extend the lifetime of battery energy storage systems for power grids.

“This project will enable my team to develop an innovative control strategy to actively manage the operating conditions of an individual battery cell using digital twin technology. It offers an excellent opportunity to implement and validate our approach in inverter-less battery energy storage systems provided by our industry partner, which uniquely enables cell-level control within the system,” Shen said.

“The project’s outcomes will strengthen Australia’s leadership in advanced energy storage technologies, support the growth of the domestic manufacturing sector, and contribute to the creation of high-skilled jobs.”

Aiming to enhance energy storage performance, the three-year project will develop new strategies to slow battery aging within each cell. It will use digital twin technology, combining deep learning and electrochemical modelling, to predict the impact of operating conditions on battery aging and regulate these conditions to control the aging process and extend battery life.

Working in partnership with Relectrify Pty Ltd, the project team will support Australia’s transition to sustainable energy by delivering longer battery life and reduced downtime so that battery systems can produce more over time.

The second project, led by Professor Yang Xiang, received $474,531 to address cybersecurity challenges in electric vehicle charging stations.

“This grant will allow my team to build advanced cybersecurity tools that address the challenges posed by the interaction between EV charging stations, diverse EVs, the national power grid and wireless communication protocols,” Xiang said.

“It creates a unique opportunity to generate novel research insights, validate solutions in real-world settings, and produce tools with strong commercialisation potential. Its outcomes support sustainable economic growth by enabling the safe uptake of EVs, reducing emissions and creating jobs.”

Electric vehicle charging stations are widely deployed, but they face complex security risks due to the diversity of electric vehicles, their connection to the power grid, and wireless communication with users. The three-year project aims to address these challenges by functionality-guided, update-guided and greybox-guided fuzzing techniques.

Working in partnership with T-POWER Pty Ltd, the project team will explore methods for testing charging stations and developing advanced tools to secure EV infrastructure and improve cybersecurity within Australia’s expanding sustainable transport sector.
