New project uses plastic waste for sustainable manufacturing of furnished homes

UOW researcher awarded funding from National Science Foundation, CSIRO for the collaborative concept

When it comes to plastic waste, the statistics are both sobering and terrifying. According to the United Nations Environment Programme, about 400 million tonnes of plastic waste are produced every year. Approximately only nine per cent of the plastic ever produced, estimated at seven billion tonnes, has been recycled.

Dr Aziz Ahmed, a lecturer in Structural Engineering in the School of Civil, Mining, Environmental and Architectural Engineering at the 51茶馆 (UOW), is part of an international cross-disciplinary team focused on finding a solution to the scourge of plastic and further integrating the material into the circular economy, to be reused for other value-added purposes.

With the support of the in the United States, and in Australia, UOW project lead Dr Ahmed is working in a team led by Texas-based social enterprise . The cross-disciplinary team also includes researchers from , and .

The project, titled Designing for Circular Economics: Creating Impact from Local Plastic Waste Using Off-Grid Containerized 3D Printers and Practice Based Learning, has been funded under the National Science Foundation鈥檚 .

As part of the project, the UOW team will focus on the net zero aspect in the design of a scalable and accessible, net-zero-footprint 3D printing-based manufacturing system that is comfortable to work in, can be moved easily between construction sites and enables lay users to design and manufacture goods from plastic waste onsite. The result? Furnished homes that are sustainable, functional, and aesthetically pleasing, with a significant socio-economic impact.

The design, which will be informed by the requirements of Habitat for Humanity, will be able to be deployed around the world, and completely open source.

Dr Ahmed said the global project was truly multidisciplinary and collaborative.

鈥淚t leverages re:3D鈥檚 expertise in 3D printing directly from plastic waste, Habitat for Humanity鈥檚 desire to scale demand for customised 3D-printed home goods made from plastic trash, The University of Texas at Austin鈥檚 expertise in engineering design, sustainability, and Life Cycle Analysis, UOW鈥檚 expertise in the built environment, and Western Sydney University鈥檚 experience in the materials science of 3D printing with recyclables.鈥�

Dr Ahmed said he was thrilled to be working on such forward-thinking and innovative research.

鈥淚magine a world that supports the sustainable manufacturing of furnished homes using local plastic waste, while not only diverting garbage from landfills but also creating jobs and training under-represented talent. What if this opportunity could be scaled globally in both rural and urban areas in a modular package?鈥�, Dr Ahmed said.

鈥淚 am very excited for the opportunity to work on such a visionary project, and even more so as it is under the umbrella of National Science Foundation鈥檚 Convergence accelerator program, which aims to accelerate convergence research into application and commercialisation.鈥�

Professor David Currow, UOW鈥檚 Deputy Vice-Chancellor (Research and Sustainable Futures), congratulated Dr Ahmed on the grant funding and said he was looking forward to seeing how the research developed.

鈥淎s we all know, the problem of how to deal with the immense amount of plastic waste on this planet is both urgent and overwhelming. This novel research could have a significant role to play in helping the environment while creating a significant and positive social impact. Congratulations to Dr Ahmed and the UOW team on their success in this prestigious round of international funding.鈥�
