Why Bangkok matters
ASEAN EV assembly base for Chinese OEM exports. Active names in and around the city include BYD Thailand, GWM, MG Thailand.
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 Sriperumbudur, Tamil Nadu, where they are weighed, logged and graded.

What the rules require in Thailand
Thailand has no dedicated EV battery take-back law yet. Retired packs are handled as industrial or hazardous waste, and processing needs DIW factory licences. Government EV incentive schemes are expanding local assembly, and battery end-of-life policy is being developed alongside them.
Dangerous goods transport follows Department of Land Transport rules, with lithium-ion batteries classed as Class 9.
- Use DIW-licensed waste processors
- Obtain permission to move industrial waste off-site
- Keep hazardous substance and waste records
- Obtain permits for any import or export of 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 Factory Act and hazardous substance and waste regulations.
