NSW celebrates recycling triumph

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.

Vegetable oil waste sees new life through WORLD project

Vegetable oil waste sees new life through WORLD project

The Politecnico di Milano, coordinator of the Waste Oils RecycLe and Development (WORLD) project, proposes a circular and sustainable process to turn used vegetable oil into a valuable resource.

Vegetable oil is used widely around the world, and cooking and food preservation is said to generate a huge amount of waste oil. Around four million tonnes of used vegetable oil are produced in Europe each year, representing just 4% of the total global amount of the widespread product. If not properly disposed of, the waste can lead to significant environmental impacts.

The goal of the WORLD project is to optimise waste vegetable oil treatment processes while improving the quality of end products, reducing waste and fostering European independence in the supply of critical raw materials.

The project proposes to recycle used vegetable oil, yielding materials used as bio-lubricants, air purification devices and fine chemical components from petroleum-free precursors. These applications are presented as a supply chain parallel to their well-known use in the production of biodiesel, although this is limited by law to 10% and concerns only the purest fraction of the waste.

In addition to economic and technological benefits, the project has a strong social and environmental impact: raising awareness of correct waste oil collection can reduce public costs related to incorrect disposal and prevent environmental damage. In addition, a life cycle analysis (LCA) will be conducted to assess the best strategies to minimise ecological, economic and social impacts by adopting a ‘zero waste’ approach.

The project study was published by the British Royal Society of Chemistry in the international journal RSC Sustainability.

“We started by observing that the waste vegetable oil recycling industry is currently based on simple decantation and filtration processes, without adequate scientific optimisation. We therefore analysed two alternative techniques — bentonite treatment and water washing — to improve their efficiency and reduce their environmental impact,” explained study co-author Andrea Mele, from the ‘G. Natta’ Department of Chemistry, Materials and Chemical Engineering at the Politecnico di Milano.

“Through an experimental approach based on the design of experiments (DoE) methodology and multivariate statistical analysis, we optimised key parameters such as temperature, pH, bentonite concentration and oil-to-water ratio. The results showed that washing with water at 75°C and pH 6 guarantees the best performance in terms of yield, productivity and environmental sustainability, minimising the production of waste and the carbon impacts of the process,” continued co-author Alberto Mannu, who recently transferred from the Politecnico di Milano to the Department of Mechanical and Industrial Engineering at the University of Brescia.

Thanks to the WORLD project, a mathematical model developed from the collected data yields predictions of equivalent CO2 emissions according to operating conditions, providing the recycling industry with a practical tool for optimising processes in line with environmental certification standards.

This scientifically validated approach marks a step forward in the transition towards an efficient and sustainable circular economy. It is said to form part of the key principles of green chemistry, open new prospects for sustainability and efficiency, and may be highly competitive from a technical/economic perspective in models of the circular economy.

The WORLD project was funded by the European Union under the H2020-MSCA program. The consortium, which is coordinated by Politecnico di Milano, includes the Universities in Burgos (Spain) and Dunkirk (France), LUT University (Finland), and the Universities of Sassari and Brescia, together with non-academic partners in Spain and Italy.
