UNSW research team develops process that converts old clothing, textiles and glass into high-quality construction materials like flat panels.
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.”
A research team at the University of New South Wales (UNSW) Business School is conducting a joint-global research project on local governments’ purchasing, procurement and waste management.
The research comes as part of the PLUS Alliance composed of UNSW, Arizona State University (ASU), and King’s College London (KCL).
The study aims to better understand the barriers and facilitators of effective purchasing, procurement, and waste management for local governments, including the social, economic, and environmental implications.
The team has already conducted research in several countries including US and Japanese local governments. They are now looking to Australian councils to participate in the project for comparative Australian data.
The team is inviting local government professionals (e.g., managers, directors, and officers) to participate in an anonymous and confidential 15 -20 minutes online-survey. They are specifically targeting professionals from the following fields of expertise:
- Waste management
- Public works
- City Planning
- Environment/environmental compliance
The aim is to collect data from local governments with 10,000 or more residents in all states and territories. To participate in the survey, click here.
A new trial aims to divert spent coffee grounds from landfill and repurpose them into higher value uses.
Planet Ark will begin the Coffee 4 Planet Ark trial in September in Sydney, in collaboration Bingo industries and with leading coffee roasters and members, such as Lavazza. Tata Global Beverages via its Map Coffee brand will collect spent coffee grounds from limited corporate businesses in Melbourne.
- Calls for recycling “latte levy” in the UK
- BioPak and Perth cafes combine to compost coffee cups
- Coffee waste powers London’s red buses
The program aims to roll out around the country in 2019 after it identifies the best and most cost-effective collection method.
Planet Ark undertook a 2016 feasibility study that found almost 2800 tonnes of spent coffee grounds are sent to landfill in Sydney alone.
Once in landfill, the grounds would begin to break down and produce methane. Diverting the spent grounds from Sydney would save approximately 1600 tonnes of carbon dioxide equivalent emissions annually, according to the study.
To develop new end uses for coffee grounds, Planet Ark has begun working with the SMaRT centre at the University of New South Wales. It has also secured a partnership with Circular Food to produce a nutrient rich soil fertiliser called Big Bio, which will utilise the collected grounds.
Planet Ark CEO Paul Klymenko said the Coffee 4 Planet Ark program was an important step in ensuring spent coffee grounds were being used to their greatest potential rather than entering landfill.
‘Currently, the vast majority of coffee grounds produced after extracting your coffee are going to landfill. Planet Ark believes in creating a circular economy where all resources are used to their greatest potential,’ Mr Klymenko said.
‘We are thrilled to be working with some of Australia’s leading coffee roasters to trial a collection and repurposing system for coffee ground waste.’
More than half a billion containers have been returned to Return and Earn reverse vending machines in NSW, eight months after the scheme launched.
The container deposit scheme aims to improve recycling rates and reduce the volume of litter in the state by 40 per cent by 2020.
- Return and Earn’s resounding numbers
- Return and Earn donates to Tathra Bushfire recovery
- NSW consumers return and earn with TOMRA app
Each eligible container is worth 10 cents when returned to a reverse vending machine or depot.
Drink containers litter currently makes up 44 per cent of the volume of all litter throughout NSW and costs more than $162 million to manage, according to the NSW Environment Protection Authority.
The University of New South Wales (UNSW) was the first educational institution to install a reverse vending machine as part of the scheme.
UNSW Senior Manager, Environmental Sustainability Will Syddall said that while this initiative helps to reduce littering and improve recycling rates, it is just one step in improving the way we create and manage waste.
“In the waste hierarchy, reducing and reusing resources is better than recycling them. We encourage the community to use reusable water bottles and coffee cups so that they can avoid disposable cups and bottles altogether,” Mr Syddall said.
“We also recognise that we have more work to do to reduce the amount of single-use plastic and other consumables used on our campuses.”
According to the World Bank, half of the plastic ever manufactured was made in the last 15 years.
The University of New South Wales Sydney’s Centre for Sustainable Materials Research and Technology has developed a new way to disrupt the traditional manufacturing sector with in-house recycling.
A world first microfactory capable of transforming components from e-waste which may reduce the amount sent to landfill has been launched at the University of New South Wales (UNSW).
The microfactory uses technology developed after extensive research at UNSW’s Centre for Sustainable Materials Research and Technology (SMaRT Centre) and is able to reduce the issue of e-waste from discarded phones and laptops causing environmental harm when sent to landfill.
NSW Minister for the Environment Gabrielle Upton said it was exciting to see new technological innovations that could transform waste management and recycling.
“I am very pleased to launch the UNSW e-waste microfactory today, a NSW home-grown solution to the waste challenges facing communities all over the world,” Ms Upton said.
“It is exciting to see innovations such as this prototype microfactory and the potential they have to reduce waste and provide a boost to both the waste management and manufacturing industries in NSW,” Ms Upton said.
The micro factory is able to operate on a site as small as 50 square metres and can be located at anywhere waste is stockpiled. It functions as a series of machines and devices that use technology to perform one or more functions in the reforming of waste products.
The UNSW microfactory is able to reform computers, mobile phones and printers, and has a number of modules for the process. The devices are first broken down, then a robot identifies useful parts, which sends them to a small furnace which transforms them into valuable resources using precise temperatures and processes developed by extensive research.
SMaRT Centre Director Professor Veena Sahajwalla said the e-waste microfactory was the first of a series of microfactories under development and in testing at UNSW that can also turn many types of consumer waste streams such as glass, plastic and timber into commercial materials and products.
An example of this is turning computer circuit boards into valuable metal allows such as copper and tine. Glass from devices can also be converted into micrometrical used in industrial grade ceramics and plastic filaments for 3D printing.
“Our e-waste microfactory and another under development for other consumer waste types offer a cost-effective solution to one of the greatest environmental challenges of our age, while delivering new job opportunities to our cities but importantly to our rural and regional areas, too,” Dr Sahajwalla said.
“Using our green manufacturing technologies, these microfactories can transform waste where it is stockpiled and created, enabling local businesses and communities to not only tackle local waste problems but to develop a commercial opportunity from the valuable materials that are created.”
Dr Sahajwalla said microfactories presented a solution to burning and burying waste items that contain materials which can be transformed into value-added substances and products to meet existing and new industry and consumer demands. This was a truly sustainable solution to our growing waste problem which also offers economic benefits available to local communities, she said.
“We have proven you can transform just about anything at the micro-level and transform waste streams into value-added products. For example, instead of looking at plastics as just a nuisance, we’ve shown scientifically that you can generate materials from that waste stream to create smart filaments for 3D printing,” she said.
“These microfactories can transform the manufacturing landscape, especially in remote locations where typically the logistics of having waste transported or processed are prohibitively expensive. This is especially beneficial for the island markets and the remote and regional regions of the country.”
The technology was developed with support from the Australian Research Council and is now in partnership with a number of businesses including e-waste recycler TES, mining manufacturer Moly-cop and spectacle company Dresden.
The SMaRT Centre is expanding its partnerships with industry, investors and local councils. The centre aims to commercialise and create incentives for the industry to use this technology and to encourage sustainable behaviours.
