Reduce demand and recycle critical materials like lithium in UK, say top engineers

A College of Sheffield professor has contributed to a new report calling for a nationwide supplies technique that addresses the rising demand for important supplies.

Printed by the Nationwide Engineering Coverage Centre, led by the Royal Academy of Engineering, the report is urging the UK authorities to develop an built-in supplies technique to scale back demand, reuse and recycle important supplies to help the UK’s present Internet Zero Technique and enhance financial safety.

Professor Joan Cordiner, Professor of Course of Engineering on the College of Sheffield, is Chair of the Nationwide Engineering Coverage Centre Working Group on Supplies and Internet Zero. On publishing the report, she stated, “The way in which we extract and eat supplies is unsustainable and we should deal with it urgently. Our report highlights the rising demand for important supplies, pushed partly by their use in batteries, energy programs and electronics. We’re not the one nation that shall be competing for these finite minerals and we’re calling on the brand new Authorities to develop a supplies technique that addresses demand and reuse of important supplies.

“For example, if we reduced the size of the UK’s larger electric vehicle batteries by 30% we could cut our lithium demand by 17% and save 75 million tonnes of rock mined for lithium by 2040—that’s the equivalent of 19 Wembley Stadiums full of rock.”

Vital supplies—as recognized by the UK authorities—embrace lithium, utilized in batteries; and magnesium, used for producing metal alloys. The UK is economically and bodily depending on many supplies which can be mined world wide. Vital supplies additionally embrace parts comparable to indium, cobalt, and niobium, and rare earth elements comparable to neodymium and praseodymium. These are usually present in very low concentrations and mining them typically entails extracting huge portions of rock or water.

The report recommends sustaining a Nationwide Supplies Knowledge Hub to observe the sustainability of supplies consumed by and in use within the UK, and allow evaluation of infrastructure plans for materials safety and sustainability. Authorities also needs to work internationally to enhance traceability and measure the worldwide impacts of our supplies’ emissions, air pollution and social harms, utilizing instruments comparable to digital passporting.

The authors suggest a brand new goal to halve the UK’s economy-wide materials footprint to assist us keep away from overconsumption and help the drive to succeed in web zero carbon emissions.

A lot of the infrastructure and applied sciences at the moment getting used to decarbonize the financial system depend on important supplies. The report recommends investing in design to scale back demand, along with extra recycling services for equipment like wind generators and batteries to retrieve the dear minerals on the finish of their life.

Authorities and trade ought to account for materials wants when planning infrastructure system transformation, to keep away from locking in dependencies on scarce or unsustainable assets

As at the moment designed, recovering critical materials from present merchandise requires extremely intricate processes, which are sometimes prohibitively costly, and a major quantity of digital waste is disposed of to landfill, regardless of containing priceless supplies.

Working Group member Mark Enzer FREng stated, “Globally, 62 million tonnes of e-waste are generated every year, and the UK produces the second highest amount of e-waste per capita. International e-Waste Day next week provides a sobering opportunity for us to reflect on the urgent need to engineer a greener future. Otherwise, the state of our environment and the supply of items like lithium-ion batteries looks bleak without more recycling and moving away from how we dispose of our old electronic devices.”

Suggestions for chopping the UK’s important materials footprint embrace:

• Make plans now in order that new infrastructure might be disassembled and reused or recycled, by means of design incentives and investing in engineering capability
• Purpose to halve the UK’s total supplies footprint to drive useful resource effectivity
• Guarantee UK power coverage accounts for important materials calls for and provide dangers, aiming to attain a future system utilizing sustainable supplies with resilient provide chains, for instance by lowering infrastructure wants by recommitting to the power demand discount goal of 15% within the Internet Zero Technique
• Evaluation and reduce important materials calls for arising from e-waste produced by information facilities and different digital infrastructure
• Develop and enhance electrical automobile charging infrastructure throughout the UK to help smaller electrical autos
• Help growth of different applied sciences, comparable to sodium-ion batteries
• Decide to introducing the ban on single-use vapes with lithium-ion batteries in England, as proposed in January 2024
• Proceed to droop deep seabed mining and encourage different nations to do the identical whereas supporting additional analysis on associated environmental impacts
