Career and publications

[edit]

Sahajwalla has been working as a professor at the University of New South Wales since 2008.^[7] She founded the Sustainable Materials Research and Technology (SMaRT) Lab at UNSW in 2008 which focused on recycling science and waste management.^[8]\n

Sahajwalla has been publishing scientific papers focusing on material engineering in journals since 1989.^[9] She has published over 380 peer-reviewed scientific papers with both the Indian Institute of Technology Kanpur where she completed her education and the University of New South Wales where she works.^[7]\n

Sahajwalla has also published many conference abstracts for international engineering and environmental conferences.^[7] She also has written and co-written many book chapters on the science of recycling including Unmaking Waste in Production and Consumption: Towards the Circular Economy.^[10]\n

Green steel

[edit]

Sahajwalla is well renowned for her contributions to building a waste-free economy. One of her most impactful projects was finding a cleaner alternative to using coal in the steel production industry. The process she created is called polymer injection technology, also known as green steel.^[11]\n

Sahajwalla discovered that recycled truck tires were a sustainable alternative to using coal as it was an environmentally friendly process that could prevent over 2 million tires from being diverted to landfills each year while simultaneously creating a renewable energy source.^[12] Tires could be ground into pellets and be used instead of coal as they released fewer greenhouse gases. Traditional steel making accounts for about 7% of global greenhouse gas emissions.^[13] Even though tires cannot be used as an alternative to all the coal used during production, they could substitute a percentage of the total coal consumed in the industry.^[14] This solution effectively lowered carbon emissions and prevented waste from being diverted towards landfills. This also will continue to be favorable as the world is rapidly de-carbonizing.^{[citation needed]}\n

Sahajwalla has continued to work with Australian steel corporations OneSteel and MolyCop to further the development of polymer injection technology. Green Steel technology has now been implemented into global steel-making operations globally.^[15] This innovation has made Australia a leader in low-emission steel making.^{[citation needed]}\n

The green steel movement has earned Sahajwalla many awards and grants which have aided her in continuing environmental research.^[12] This Project has also earned her international recognition which landed her positions on multiple government organizations focusing on climate change. Her green steel process has also been listed as one of the \u201cinnovations that could change the way we manufacture\u201d by the US Society for Manufacturing Engineers in 2012.^[12] This innovation also won Sahajwalla the Australian Innovation Challenge in the same year.^[16] Her innovation in green steel technology also has earned her the 2019 BHERT (Business Higher Education Round Table) Award.^[15]\n

Micro-factories

[edit]

Sahajwalla is also known for innovating micro-factories. She discovered that small scale factories that were comprised one or more specialized machines were much more sustainable. Factories of this scale could be implemented in existing manufacturing businesses to recycle available waste.^[17]\n

She launched her first micro-factory at the Sustainable Materials Research and Technology (SMaRT) Lab based at the University of New South Wales Kensington Campus in 2018. Her first micro-factory was focused on recycling e-waste from old technology. She found that technological waste housed many precious metals and rare earth minerals.^[18] This micro-factory salvaged gold, electrical conductors, and many other rare materials. After collecting these materials, she processed them through thermal techniques so that they could be recycled in new technology.^[19] Glass and plastic used in electronics could also be melted down and used in industrial-grade ceramics and plastic filaments in 3D printing.^[20] This new concept revolutionized the recycling process for e-waste. Her contributions to this new e-waste recycling technology allowed her to continue to open new micro-factories targeted at recycling different materials.^{[citation needed]}\n

Sahajwalla\u2019s second micro-factory was launched in 2019 targeting the recycling of glass and textiles into green ceramics.^[8] Glass is one of the easiest materials to recycle but due to the expensive nature of recycling, many countries tend to stockpile it instead. This process is expensive due to the cross-contamination of glass with lids and labels.^[17] Sahajwalla's recycling method eliminates the need to separate these materials. Her ceramics are made of a blend of many different materials. This blend gives these ceramics strength and sound absorbency properties.^[17] These ceramics included tiles and furniture which can be used in new architectural developments. She has worked with numerous architectural firms to develop green buildings and infrastructure. Some projects that Sahajwalla has worked on include a Mirvac collaboration with Marrickville and Co., Hunters Hill library, and recycled rubbish bins for the city of Canberra.^[7]\n

These micro-factories have been successful in helping local and federal governments recycle materials that would otherwise be diverted to landfills.^[21] These micro-factories have created recycling factories for rural areas and have created jobs for many Australians. This is important as previously, waste in rural areas would have to travel to bigger cities to be recycled. This was not a sustainable practice because it produced unnecessary carbon emissions.^{[citation needed]}\n

Contributions to government organizations

[edit]

Sahajwalla has been a member of the Australian Climate Council, NSW Circular and the Australian Climate Commission.^{[citation needed]}\n

Sahajwalla is a councillor on the independent Australian Climate Council and has been awarded the Australian Research Council Laureate Fellowship & Georgina Sweet Award in 2014.^[22]\n

She was appointed director of the NSW Circular Economy Innovation Network in 2019 by the state government. NSW Circular is a government-funded body that aims to make NSW a zero-carbon circular economy. Sahajwalla manages the environmental efforts made by the organization and provides a face to the organization.^[23]\n

Sahajwalla was a commissioner on the Australian Climate commission alongside Professor Tim Flannery and Professor Will Steffen. The Australian Climate commission was responsible for releasing \u201creliable and autoreactive\u201d information about climate change to the Australian public.^[24]\n

Sahajwalla also is the leader of the green manufacturing department of the ARC Industrial Transformation Research Hub. This department focuses on combining academic research with the Australian Industry to improve technology. This has ensured that the industry has the best research which has translated into environmental and economic benefits for the Australian economy.^{[citation needed]}\n

Recognition

[edit]

Sahajwalla is one of Australia\u2019s best-known engineers. She has been invited to talk at many international conferences including the Farm2Fork Summit in 2019, TRANSFORM conference in 2019, and the Falling Wall conference in 2018. Sahajwalla was also named one of Australia\u2019s 100 most influential engineers as well as one of Australia\u2019s most innovative engineers by Engineers Australia in 2015 and 2016 respectively.^[7]\n

Sahajwalla also runs a mentoring program for women in science called Science 50:50 with the Australian Research Council (ARC). This program aims to inspire Australian women to pursue degrees and careers in Science and Technology.^[25]\n

Achievements

[edit]

Known internationally as the inventor of green steel,^[27] Sahajwalla's research is recognized for changing the way the properties of carbon-bearing materials are understood, including coal, coke, graphite, plastics, and rubber. Sahajwalla's work has had a significant impact on the theory and practices that form the basis of operations of the iron-making, steel-making and ceramics industries. Of particular importance is her demonstration that waste plastics and waste rubber can be partial replacements for coal and coke in steel-making.^[28]\n

Sahajwalla's unique focus on the evolution of carbon properties in high-temperature conditions has not only advanced scientific understanding of materials processing, but has provided cost-effective opportunities for industries to move towards sustainable and environmentally friendly production methods.^[29]\n

Sahajwalla has also revolutionized the methods of recycling in Australia. Her work to introduce small specialized recycling factories has significantly reduced carbon emissions and provided rural communities a way to up-cycle used items.^[8]\n
