Why Monterrey matters
North American EV supplier park and assembly expansion. Active names in and around the city include Tesla supplier park, KIA Mexico.
Manufacturing clusters generate production scrap and off-spec cells during line ramp-up, warranty returns from early vehicles, and validation packs from test tracks. The material is usually single-chemistry and well documented, which makes it some of the cleanest feed in the network.

How collection works here
We run scheduled scrap collections from plant gates and tier-one suppliers, with dedicated bins per chemistry and a weighbridge reconciliation against each supplier's scrap log. Off-spec cells that never entered a vehicle are graded separately because their value profile is different from end-of-life packs.
Loads move in Class 9 compliant transport with pre-filled dangerous goods paperwork to Monterrey, Nuevo Leon, where they are weighed, logged and graded.
- Cell and pack assembly plants
- Tier-one module suppliers
- Vehicle assembly lines
- Validation and test centres
What the rules require in Mexico
Mexico classifies spent lithium-ion batteries as hazardous waste under its NOM standards, and large generators must file waste management plans. Collectors, transporters and processors need SEMARNAT authorisation. Growing EV assembly in the north is making production scrap an important feedstock.
Hazardous materials transport follows SCT regulations, with lithium-ion batteries classed as Class 9.
- Register as a hazardous waste generator and file a management plan where required
- Use SEMARNAT-authorised transporters and treatment facilities
- Keep waste manifests and annual operating reports
- Obtain permits before exporting battery waste
Field note
What you get paid and what you file
Settlement is quoted per pack after measured state of health, not by guesswork on age. Modules holding 75% or more of rated capacity settle at second-life rates; the remainder settle against black mass metal content.
Certificates carry achieved recovery percentages and downstream vendor disclosure for reporting under General Law for the Prevention and Integral Management of Waste (LGPGIR).
