The West Nowra Waste and Recycling Depot will be the first of its kind in Australia to recycle glass waste and textiles into green ceramics. Read more
Waste Management Review speaks with Veena Sahajwalla about a decentralised approach to sustainable materials research and technology.
Most Australians across all states and demographics believe the recyclables they put into their council bins are ending up in landfill, according to new research from the University of New South Wales (UNSW).
The series of surveys has also found that 49 per cent of people believe that green and eco-friendly efforts will not have an effect in their lifetime, with 63.8 per cent of those older than 65 seeing no benefits being realised.

Key findings also report that 72.4 per cent of people would recycle more of the material if it was reliably recycled.
Confusion also surround which level of government is responsible for residential waste and recycling services, with some people thinking industry instead of government is responsible for waste management.
UNSW’s Centre for Sustainable Materials Research and Technology (SMaRT) Director Veena Sahajwalla said rising stockpiles and increasing use of landfill, in the absence of a coordinated government solution to a waste problem, had not been lost on consumers.
“Each council is fending for themselves right across Australia and while the meeting of federal and state environment ministers earlier this year made an important announcement about a new National Waste Policy stating that by 2025 all packaging will be re-usable, compostable or recyclable, we don’t have to wait another seven years for this decision to come into effect,” Dr Sahajwalla said.
“It is clear on this issue that people want action, and they want governments to invest and do something now.
“A number of councils and private business are interested in our technology but unless there are incentives in place, Australia will be slow to capitalise on the potential to lead the world in reforming our waste into something valuable and reusable.”
UNSW’s SMaRT Centre launched a demonstration e-waste microfactory in April, which is able to recover the components of discarded electronic items for use in high value products.
UNSW is also finalising a second demonstration microfactory, which converts glass, plastics and other waste materials into engineered stone products, which look and perform as well as marble and granite.
“Rather than export our rubbish overseas and to do more landfill for waste, the microfactory technology has the potential for us to export valuable materials and newly manufactured products instead,” Dr Sahajwalla said.
“Through the microfactory technology, we can enhance our economy and be part of the global supply chain by supplying more valuable materials around the world and stimulating manufacturing innovation in Australia.”
