UL ECOLOGO^® Certification for Circularity of Batteries

The UL ECOLOGO^® Certification is a scientifically backed process that begins with a desktop audit, where documentation is provided and reviewed. UL Solutions provides a checklist of document submission requirements for each criterion listed in the Standard.

This Standard establishes a multi-criteria framework for evaluating the circularity on the basis of durability, recyclability, reusability, and recoverability for medium and large, secondary (rechargeable) batteries, and provides methods and metrics to assess the implementation of circularity economy principles aimed to reduce adverse environmental impacts associated with battery design, manufacture, use and end-of-life management practices.

This Standard includes both required and optional criteria, with a maximum of 102 points available and three levels of achievement.

Annual surveillance evaluations from UL Solutions are required for manufacturers to maintain certification. Customers must notify UL Solutions of any changes to the product that may affect certification and require reassessment. UL Solutions requires a full recertification review every three years to assess whether the current certification criteria are being upheld.

This UL ECOLOGO^® Certification to UL 3601 empowers businesses and governments to advance circularity in battery systems through actionable interventions. The Standard provides a measurable framework to assess and improve the reuse, repurposing and recycling of secondary batteries.

Governments and institutions can embed UL 3601 criteria into procurement policies, helping demonstrate that certified products meet circularity benchmarks. This can drive demand for responsibly designed batteries and encourage manufacturers to adopt circular practices.

By helping standardize and validate circular processes, UL ECOLOGO^® Certification to 3601 helps reduce uncertainty for investors and operators. The Certification supports scalable business models that benefit local economies and help reduce environmental harm.

Our Certification facilitates greater standardization and validation of circular processes, enabling more visibility into repurposing and recycling models and their risks for operators and investors.

UL ECOLOGO^® Certification for Batteries indicates that a manufacturer complies with the UL 3601 Standard. 
Our Certification helps buyers, regulators and supply chain partners recognize and choose circular battery solutions. This contributes to a broader global movement toward innovation, accountability and sustainable battery production.
