On August 28, 2025, in Hanoi, the Institute of Building Materials (VIBM) held a working session with VinUniversity and professors from the United Kingdom to discuss research on recycling used batteries into construction materials. This initiative is considered an important step toward sustainable development, contributing to environmental protection and more efficient resource use in the construction sector.

Participants included Dr. Phung Thi Viet Bac and Dr. Nguyen An Giang (Center for Environmental Intelligence, VinUniversity); Dr. Akilu Yunusa-Kaltungo (Reader) and Dr. Clara Cheung (Reader) (University of Manchester, UK); Professor Patrick Ackom Manu (University of the West of England, UK); and Associate Professor Dr. Luong Duc Long (Vice President of the Vietnam Cement Association). Representing VIBM were Dr. Nguyen Quang Hiep, Director of the Institute, along with leaders of its affiliated units.

During the session, experts shared the latest research on utilizing used batteries in the production of cement, concrete, and other construction materials. Initial experimental results conducted by VinUniversity indicate that certain components from spent batteries can partially replace raw materials in cement production. This approach helps conserve natural resources, reduce greenhouse gas emissions, and address hazardous waste. It represents a promising research direction aligned with the circular economy and the development of green construction materials.

According to statistics, Vietnam generates approximately 70,000 to 100,000 tons of used batteries annually. If not properly treated, these batteries can contaminate soil, water, and air due to heavy metals and toxic chemicals. Meanwhile, the construction sector is highly energy- and resource-intensive, accounting for about 36% of global energy consumption and nearly 40% of energy-related CO₂ emissions. Therefore, recycling used batteries into construction materials offers a dual benefit: reducing environmental pollution from battery waste while lowering emissions in the construction industry.

Speaking at the meeting, Dr. Phung Thi Viet Bac expressed interest in collaborating with VIBM to validate the quality of project outputs and gradually move toward commercialization. She emphasized that cooperation between domestic research institutions and international universities would provide a strong scientific foundation and expand real-world applications.

On behalf of VIBM, Dr. Nguyen Quang Hiep affirmed that research on recycling used batteries into construction materials is a key step in the Institute’s strategy to develop and apply new, environmentally friendly materials. “The Institute of Building Materials is ready to collaborate with both domestic and international partners to develop recycled products from used batteries, contributing to environmental protection and supporting Vietnam’s goal of achieving net-zero emissions by 2050,” he stated.

In recent years, VIBM has implemented numerous research projects on using industrial by-products such as fly ash, blast furnace slag, and gypsum to produce cement and unbaked bricks. Expanding into battery recycling further reinforces the Institute’s pioneering role in sustainable construction materials development. At the same time, international collaboration with leading UK universities will enhance research capacity, facilitate access to advanced technologies, and help Vietnam gradually master innovative waste treatment and recycling solutions.

At the conclusion of the meeting, both sides agreed to maintain close cooperation, continue in-depth research, and conduct further testing and product quality assessments. These efforts are expected to pave the way for broader applications, supporting the transition of Vietnam’s construction industry toward a greener, more circular, and sustainable future, while contributing to the government’s commitments to addressing global climate change.
