Recycling lithium batteries It has become a fundamental piece for the energy transition and technological sustainability at a global level. More and more companies, governments and research centers are working to close the life cycle of these devices., increase the recovery of strategic materials and minimize their environmental impact.
In recent years, the growing demand for critical materials for batteries—such as lithium, cobalt, or nickel—has led to the creation of projects, international alliances, and new regulations that seek to manage waste more efficiently and promote a circular economy in the sector.
Chile promotes recycling
Chile has taken firm steps with the implementation of initiatives such as the Circular Route, the result of a collaboration between Entel and Midas Chile. The objective is to bring the electronic recycling —including lithium batteries— to the public, especially in regions where infrastructure was insufficient. In the last campaign, hundreds of unused devices in various locations in the north and center of the country, exceeding 1.600 units when adding devices delivered at fixed points.
A key factor is the REP Law (Extended Producer Responsibility), which requires manufacturers and importers of priority products—including batteries—to finance the collection and recovery of waste generated. The Chilean model thus seeks consolidate the circular economy and reduce the impact of waste by increasing the recovery of materials essential for the energy transition.
New companies and technologies in Spain
In the north of Spain, companies such as Kudebatt have emerged with the focus on maximize the life of lithium-ion batteries and minimize their environmental footprint. Kudebatt collects, analyzes, and decides whether a battery can be reused for energy storage or whether it should be recycled to recover materials. In addition, advises companies on safe handling and storage, with the goal of making battery “end-of-life” safer and more sustainable.
Kudebatt's project is scalable to different regions and collaborates closely with research centers such as CIDETEC, developing disruptive technologies for comprehensive recycling of all components. The medium-term challenge is become a national reference and lead the efficient recovery of materials such as lithium, cobalt, and nickel within a sustainable and local value chain.
International projects and advanced technology
The internationalization of the circular economy in lithium batteries is evident with the entry of giants such as Hainan Trailblazer New MaterialsThis Chinese company, now active in Latin America following strategic agreements, addresses everything from the research and development of new materials to the recycling and reuse of used electric batteries, seeking to create complete value chains that include marketing, services, and rare earth metallurgy.
This investment and technological interest is also reflected in the emergence of new facilities in countries like the United States. In Oklahoma, for example, lithium-ion battery recycling and processing plants have opened, alongside public initiatives to attract investment in energy infrastructure. These plants recover key materials such as copper and nickel. and offer a local response to the growing dependence on imports and demand.
Circular economy and critical raw materials in Europe
La European Union sets a clear course with objectives such as achieving by 2030 up 25% of its consumption of critical raw materials through recycling. EU legislation and the introduction of specialized technologies allow for the recovery of valuable materials from disused batteries, although the challenge remains. increase the collected volumes and address the fact that much electronic waste remains stored in homes.
One of the central messages is that the consumer action It is key: deliver old batteries to official points It helps keep these resources in the economic cycle and supports the circular economy, which is vital for reducing the extraction of new materials and the environmental impact of the technology industry.
Innovation and alliances: global examples
International companies like Redwood Materials have made significant progress in recovering up to 95 % of critical metals present in batteries and apply recycling systems closed circuitThis approach not only reduces energy and water consumption compared to traditional mining, but also minimizes carbon emissions. In addition to partnering with major electric vehicle manufacturers—such as Toyota, BMW, Ford, and Volkswagen—these companies are focusing on optimize the supply chain and reduce dependence on imported raw materials.
The commitment to hydrometallurgical technologies and the expansion of recycling capacity go hand in hand with public-private partnerships and the search for financing to scale these solutions and make them viable on a large scale.
Biotechnology research and new approaches
Innovation is even reaching areas such as urban biomining, where science is exploring the use of microorganisms to recover metals from used batteries. Seminars and interdisciplinary projects in Chile are studying the biotechnological and ecological potential of salt flats, seeking disruptive recycling strategies and focusing on the link between biodiversity and sustainable technology.
The role of regulation and social awareness
The success of lithium battery recycling depends largely on the development and implementation of appropriate regulations and the citizen awarenessThe responsibility of manufacturers and importers, along with adequate infrastructure and collaboration between the public and private sectors, provide the necessary framework for efficient and safe recycling. Furthermore, in both Europe and America, the importance of depositing unused devices at official disposal points and avoiding improper disposal is emphasized, given the risks that some defective batteries pose to safety and the environment.
Lithium battery recycling is currently in a phase of growth and professionalization, where the following converge: technological innovation, regulatory development, international alliances and responsible action by both businesses and consumers. These factors are laying the foundation for a key industry in the transition toward more sustainable energy and production models, with the goal of making the most of available resources and reducing the risks associated with the disposal of highly polluting components.
