Waste Batteries and Chemicals from EV Battery Plants: Applicable Disposal Rules

3 min readFLAT LAW FIRM

An EV battery plant generates a waste stream ordinary factories never see: defective cells, end-of-life batteries, electrolyte and precursor chemicals. This stream is simultaneously hazardous waste by code and inside the extended producer responsibility (EPR) mechanism — two obligation frameworks running in parallel that the plant’s environment team must govern together.

Two obligation frameworks for battery-plant waste

  • The hazardous waste framework — Decree 08/2022/ND-CP (as amended by Decree 05/2025/ND-CP): waste batteries and many battery-production chemicals are listed hazardous waste by code; the plant is a waste source owner with full registration, storage and electronic manifest duties.
  • The EPR framework for batteries — Article 54 of Environmental Protection Law 72/2020/QH14 and Decree 08/2022/ND-CP: batteries are a product group whose producers and importers must organise collection and recycling at mandatory ratios and specifications on a roadmap, or contribute financially to the Environmental Protection Fund instead.
  • A fire risk specific to waste battery storage — defective lithium cells can self-ignite (thermal runaway): waste battery stores must be separated, with suitable fire protection and incident response — a practical requirement beyond ordinary hazardous waste store standards and closely examined in fire appraisals.
  • Treaters and recyclers need matching capability — battery recycling demands technology and an environmental licence with the right treatment component; Vietnam’s qualified-provider market is still thin, so plants need long-term contracts and real capability diligence, not paper licences alone.

Designing waste-battery governance at plant build stage

  1. Put battery waste streams into the environmental licence and EIA dossiers from the start, with volumes forecast by capacity, avoiding licence amendments when output scales.
  2. Choose the EPR model: join a collection-recycling system on the mandatory ratio roadmap or contribute to the Fund, and cost it into product pricing from the first operating year.
  3. Design the waste battery store as its own fire-safety item: defective cells in dedicated containers, thermal monitoring and an isolation procedure for swollen or hot cells.

Waste batteries are a problem an EV battery plant cannot ‘figure out during operations’. Hazardous waste duties, EPR duties and the fire safety of this very stream must be designed together with the production line — because all three attach to infrastructure decisions (stores, fire systems, recycling contracts) that are very hard to retrofit once the plant is running.

Frequently asked questions

How are defective and waste batteries handled?

Classify them by hazardous waste code, store them in a compliant dedicated store, and transfer them to a licensed battery treater or recycler with electronic manifests under Decree 08/2022/ND-CP.

Are waste batteries hazardous waste?

Yes: waste batteries are listed hazardous waste, and the plant simultaneously carries EPR collection and recycling duties under Article 54 of the Environmental Protection Law.

What conditions must a waste battery store meet?

A separate store for waste batteries and defective cells, fire protection matched to lithium thermal-runaway risk, monitoring and an isolation procedure for abnormal cells — beyond general hazardous waste store rules.
