The Path to a Circular Economy

Environment National Science Week

Join us for an introduction to recycling for the Circular Economy and learn how you can maximise the use of your valuable resources to contribute to innovation, growth and job creation.
'The Advanced Manufacturing Growth Centre (AMGC) is hosting an event to introduce recycling for the circular economy. Circular economy is about changing the way we produce, assemble, sell and use products to minimise waste, and to reduce our environmental impact. The circular economy can be great for business; by maximising the use of our valuable resources, and by contributing to innovation, growth and job creation. AMGC is facilitating strong linkages between industry, government, researchers, local councils, and the community to find new and clear pathways to meet the challenges of recycling and the circular economy. A circular economy is about valuing our resources, by getting as much use out of products and materials as possible and reducing the amount of waste we generate. For example, using recycled materials in manufacturing, repairing household goods before buying new ones, or repurposing items that are no longer needed. Bringing together key stakeholders to accelerate partnerships and opportunities to help build the circular economy across Australia to address the waste and recycling issue and enhance manufacturing and industry capability. Keynote Speaker Professor Veena Sahajwalla, Director of the UNSW SMaRT Centre for Sustainable Materials Research and Technology Professor Sahajwalla is one of Australia’s leading engineers. She is known for her role as a judge on the ABC television show, The New Inventors and as a councillor on the independent Australian Climate Council. As Founding Director of the Centre for Sustainable Materials Research and Technology, Veena and her team are working closely with industry partners to deliver the new science, processes and technologies that will drive the redirection of many of the world’s most challenging waste streams away from landfills and back into production; simultaneously reducing costs to alleviating pressures on the environment. She is reimagining the global supply chain by demonstrating the viability of ‘mining’ our overburdened landfills to harness the wealth of useful elements like carbon, hydrogen and materials like silica, titania and metals embedded in our waste. Panel Discussion with circular economy industry leaders including: Michael Sharpe – AMGC National Director, Industry Professor Veena Sahajwalla – NSW CEIN Director Ashley Brinson – NSW CEIN Co-director Debbie Hambly – Milk Bottle Collective Ian Hudson – Industry Capability Network Tim Askew – Hunter Joint Organisation of Councils Marta Fernandes – Nespresso Brooke Donnelly – Australian Packaging Covenant Organisation (APCO) Paul Klymenko – Planet Ark Nishi Vissamraju – Downer'

Mine electrification drives potential for reduced costs

Environment Australian Mining

The electrification of mines is not only good for the environment, but could improve project economics and strengthen licence to operate, according to mining executives from Australia and overseas.
'The electrification of mines is not only good for the environment, but could improve project economics and strengthen licence to operate, according to mining executives from Australia and overseas.The executives’ opinions were noted in an Ernst & Young (EY) survey carried out as a collaboration by the University of Queensland and the University of British Columbia in Canada.EY’s report noted that Chile had outperformed other countries when it came to mine electrification due in part to a 2013 law stating that 20 per cent of the country’s energy production should come from renewable sources by the year 2025 (and 70 per cent by 2050). The Barrick-Antofagasta Zaldivar copper mine is the first mine in the country to operate on 100 per cent renewable energy, which it achieves through a mix of hydro, solar and wind power. “The world is already ushering in a new energy system, where cleanly generated electricity will power almost every aspect of our lives,” EY Global Mining and Metals leader Paul Mitchell said. “The mining sector is on the verge of an electrification revolution, driven by significant cost reduction potential, lowered carbon emissions and improved worker health benefits.” The report outlined that phased implementation of electric power was preferential to ensure companies would get full value from its implementation and lower risk, stating that the switch would require reskilling of workers.It also noted that for the successful integration of electrification at mines to occur, the sector would require partnership between original equipment manufacturers (OEMs), mining companies and government.The collaboration between Newmont Goldcorp, Swedish OEM Sandvik and Canadian OEM MacLean Engineering at the Borden gold mine in Canada was cited as an example of this.Newmont Goldcorp has reportedly halved ventilation costs, delivered a 70 per cent reduction in greenhouse gas emissions, and improved safety performance and staff wellbeing since the company made the switch to electric power at the site.Another example was the partnership between Epiroc, LKAB, ABB, Combitech and Volvo in Sweden, who are testing automation and electrification technologies at ore fields in northern Sweden. “I don’t believe that mining companies or OEMs need to develop the technology independently,” said one interviewee who was surveyed in the report. “I believe a lot of these technologies will be commodity technology at the end of the day, so none of this should be proprietary or be seen as a competitive advantage.” .

Lithium Australia (ASX: LIT) has continued advancing its efforts in creating a sustainable and vertically integrated battery mineral mining, processing, manufacturing and recycling business.In this morning’s company update, Lithium Australia
'Lithium Australia (ASX: LIT) has continued advancing its efforts in creating a sustainable and vertically integrated battery mineral mining, processing, manufacturing and recycling business.In this morning’s company update, Lithium Australia revealed it had made “significant progress” in its partnership with major Chinese battery manufacturer DLG Battery.Back in May, the duo announced a letter of intent had been signed to form a joint venture business to supply and sell lithium-ion batteries, packs and modules throughout Australia.Part of the deal was commercialising Lithium Australia’s wholly-owned subsidiary’s VSPC’s cathode powder in China.The duo has now formalised its business plans including objectives, goals and budgets, with representatives from both companies to meet this month and develop the corporate structure for implementing these plans.DLG Battery has continued testing VSPC’s cathode powders along with customers in Japan and India.Recycling spent lithium-ion batteries Meanwhile, Lithium Australia has also progressed its work into recycling spent lithium-ion batteries, with the goal of reducing the amount of batteries sent to landfill.The Australian Nuclear Science and Technology Organisation (ANSTO) in Sydney is carrying out the next round of test work and will finalise a metallurgical flow sheet on recovering all battery minerals from used lithium-ion batteries.As part of the research, design of a pilot plant has begun, with the flow sheet aiming to recover lithium from batteries as lithium phosphate, which can then be used in lithium iron phosphate cathode materials or converted to lithium hydroxide.To firm up its battery recycling strategy, Lithium Australia has taken a stake in Envirostream Australia Pty Ltd , which currently operates Australia’s only facility for shredding lithium-ion batteries.The company generates a powder containing critical battery minerals which is then exported for refining.Lithium Australia expects to secure its full 18.9% interest in Envirostream by mid-August.With only 3% of spent batteries currently recycled, Envirostream is rolling-out battery collection points across Australia and has now established an extra 50 collection points since its collaboration with Lithium Australia was announced in April.Commenting on today’s updates Lithium Australia managing director Adrian Griffin said the company’s activities had placed it in a “unique position” to provide sustainable solutions to the battery industry. “We are passionate about improving the utilisation of resources and reducing negative impacts on the environment as we do so,” Mr Griffin added.Lithium and vanadium exploration Meanwhile, as part of Lithium Australia’s vertical integration strategy, it revealed it had completed 22 holes at the Youanmi lithium project for a total of 882m.According to Lithium Australia, most of holes contained visible lithium lepidolite mineralisation, which it is looking to process into battery-grade lithium chemicals using the company’s proprietary SiLeach process.In addition to searching for lithium minerals at Youanmi, Lithium Australia has also identified vanadium at the project and firmed up a maiden vanadium resource of 185 million tonnes at 0.33% vanadium pentoxide.A four-hole drilling program targeting the vanadium mineralisation has also been completed with samples sent for metallurgical testing at ANSTO.Lithium chemicals During the last few months, Lithium Australia has continued refining its proprietary lithium chemical processes and has lodged patents for various parts of its lithium phosphate precipitation and refining stages.The company has also progressed work involving converting lithium phosphate directly into lithium hydroxide which commands a premium price to lithium carbonate in the lithium-ion battery market.Under its lithium chemical strategy, Lithium Australia continues working on cheap and simple procedures which can remove impurities from lithium phosphate to boost product quality and consistency, with recent test work at ANSTO resulting in a decrease in sodium, potassium and sulphur impurities.Additionally, Lithium Australia is advancing its LieNa proprietary processing technology which uses a caustic digest technique to convert spodumene concentrate into lithium chemicals.A feasibility study is underway using LieNa and investigating ways to optimise leach, impurity removal and product recovery processes.By mid-morning trade, shares in Lithium Australia had lifted 12.50% to reach $0.054. .
