- 37m tonnes waste sent to landfill per year
- 2.7 tonnes waste generated per person annually
Facts & figures
More waste is being produced than ever before. Through nationwide research and industry partnerships, we can transform this waste into reusable materials and move towards a circular economy.
We have a whole-systems thinking approach towards a circular economy, in which resource extraction, materials production and end-of-life processing form a closed loop with minimal waste.
With our expertise in process intensification, we have developed new technologies that are now utilised in small, modular plants that process waste at its source, producing valuable niche products.
With the help of industry and government, we want to apply these advanced manufacturing methods to transform the waste industry in urban and regional areas.
We're designing technology to recover useful chemicals from waste water streams such as sewage or mine-tailings dams.
We're pursuing basic and applied research in membrane science and technology for waste water applications. Specific research interests include:
We're focusing on developing novel processes to extract value from waste water through biological conversions into high-value products. We're using various microorganisms (algae, fungi, bacteria, yeast) to produce biopharmaceutical, health care and nutritional products (for example, PUFAs, carotenoid pigments, cholesterol-lowering drugs, vitamins, and nutraceticals). To do this we are using a suite of technologies:
We're using technologies to re-process biological waste products from landfill, such as organics and other municipal solid waste, to create high energy density fuels.
There is a well-known problem with the accuracy and completeness of waste data in Australia, which is why we have developed an alpha version of the Waste Atlas dashboard covering NSW waste data from 2014-2018 fiscal years in an interactive geospatial map, as a step towards solving this waste data problem.
The data is presented for the various Local Government Areas (LGAs) in NSW, and aggregated information for LGA clusters. We apply data analytics and visualisation techniques for the waste management sector, providing insights and information sharing opportunities.
Our Waste Atlas presents estimates of the equivalent carbon dioxide emissions associated with that waste and estimates of its calorific energy. This Waste Atlas (Alpha) presents other information on waste like:
This digital Waste Atlas represents an important step forward in pioneering an open waste data platform, inviting opinion and collaboration amongst government, industry, academia and the public in sustained efforts towards building a truly open circular economy.
We intend for our Waste Atlas to help inform policy makers and waste service providers, while assisting households to understand and manage their individual waste.
This project utilises the hydrothermal liquefaction pilot plant at the School of Chemical and Biomolecular Engineering. This is a continuous-flow kilo-scale research facility and the first of its kind in Australia.
It converts organic and other solid matter including waste plastics into fuels and chemicals under hydrothermal conditions, submerging them in water up to 300 degrees Celsius and subjecting them to pressure equivalent to up to 250 atmospheres.
We intend to address the challenges associated with feedstock handling, preparation and standardisation using our feedstock preparation facilities.
The plant has converted various biomass feeds (including algae starch crops, aquatic plants, woods and grass) into bio-crudes. It is now in this project being used for testing MSW feedstock blends.
The resulting products will be further refined through catalytic processes using our novel catalysts in reactions such as reforming, hydrotreating, gasification, pyrolysis and transesterification. We will produce various high value fuels and chemicals with targeted and precise properties.
Being able to reprocess waste products from one or more industies into useful items such as building materials is an important area of waste minimisation.
Our research is aiming to find more novel and large-scale waste recovery options.
We aim to reprocess waste products from one or more industries (power generation, mining, steel, glass, aluminum, agricultural) into various useful materials such as construction industry products.
Our goal is to identify novel and large-scale routes for converting carbonated blends of industrial waste, and novel product formulations of X construction materials with targeted specially properties.
For example, we have developed processes to transform fly-ash into a new cement blend, utilising fly ash and carbon dioxide wastes from power plants to produce future sustainable construction materials.
We're also using advanced 3D printing manufacturing techniques to integrate product design (ink) with application requirements.
To minimise wastes and emissions from industrial manufacturing, we're using our enterprise-wide models to design future industrial ecology eco-parks.
This requires systems approaches where energy and materials are recovered and recycled in a highly-integrated manner, achieved through the use of optimisation methods, accurate techno-economic estimation and life cycle analysis.
The result is a blue print for a future bio-manufacturing hub that maximises efficiencies and minimises wastes and emissions.
We're recovering valuable resources from electronic waste products and from emerging industries such as renewable energy and energy storage.
We're investigating the mechanisms of e-waste bioleaching and hydropyrolysis in order to develop new low energy processes that maximise recovery of materials including metals and polymers from e-waste.
We're focusing on addressing the waste problem emerging from the roll out of renewable energy technologies, including waste materials generated from solar energy and energy storage technologies.
The first targets in this project are solar PV panels and battery material wastes. A key activity in this project will be life cycle analysis to track the flow of materials in this sector and to estimate the environmental and other impacts these emerging wastes will have.
