Introduction
In the UK, technology metals are indispensable for various high-tech and clean-tech industries. A circular economy (CE) for technology metals in the UK aims to enhance material security and energy efficiency.

The CE model offers a sustainable alternative to the traditional linear economy by focusing on reducing waste and keeping products and materials in use for as long as possible while regenerating natural systems (Ellen McArthur Foundation). This requires a fundamental shift from the ‘take, make, dispose’ model to a more sustainable system where materials are reused, repaired, refurbished, and remanufactured. The approach not only addresses environmental concerns but also supports sustainable economic growth by reducing reliance on imports and optimising resource productivity.
Roadmaps provide a strategic framework to guide stakeholders in implementing circular economy (CE) principles, helping to ensure that the transition to a low-carbon future is both environmentally sustainable and economically resilient.
Much attention has been given to lithium-ion batteries (LIBs) for use in electric vehicles (EVs) because of the importance of the car manufacturing industry to the UK. The battery is the most obvious and largest new component in an EV, with key raw materials, notably lithium and cobalt designated as critical minerals (see below). If materials from overseas are at risk, trying to make better use of the materials we already have in circulation is an obvious strategy.
A circular economy is particularly crucial for lithium-ion batteries (LIBs), given their pivotal role in powering electronic devices, electric vehicles (EVs), and energy storage systems. LIBs contain several critical metals, including lithium, cobalt, nickel, and manganese, which are essential for their functionality but also pose significant supply security, environmental, and geopolitical challenges. The UK’s commitment to phasing out combustion engine vehicle sales by 2030 or 2035 further underscores the importance of LIBs in meeting national net-zero targets.
Met4Tech
This roadmap is produced by the UKRI Interdisciplinary Circular Economy Centre for Technology Metals (Met4Tech.org). It describes important considerations about developing a circular economy (CE) roadmap for lithium-ion battery materials (LIBs) used in electric vehicles (EV’s) in the UK, covering nickel, manganese, cobalt and lithium iron phosphate chemistries. This report addresses the specific challenges and opportunities presented by the technology metals the LIB sector needs centred on the UK and using particularly the examples of lithium and cobalt. The messages draw on best practices and insights from existing CE strategies developed through stakeholder consultations and new interdisciplinary research across the whole LIB value chain in the Met4Tech Centre.
Technology metals, critical minerals & net zero
The transition to net zero will have profound implications for the mining and metals sector because many clean technologies – such as batteries, electric vehicles (EVs), fuel cells, electrolysers, wind turbines and solar panels – depend on critical metals like lithium, cobalt, nickel, copper, manganese, and rare earth elements. These metals are classified as ‘critical’ (=critical minerals) due to their economic importance, scarcity of alternatives, and vulnerability to supply chain disruptions. As global decarbonisation efforts accelerate, the demand for these technology metals is surging (IEA, 20241, Ahuja et al., 20252 ), making the future increasingly metal-intensive and presenting significant challenges to acquire sufficient metals in the time available and to produce a metals economy which meets good sustainability standards.
