Thailand EV Battery Recycling & Second-Life 2027 Market Intelligence

Operator playbooks

PTT-Foxconn Horizon Plus (Arun Plus, PTT group): the 60:40 Foxconn-PTT joint venture producing EVs in Chonburi anchors the largest Thai-domiciled reverse-logistics opportunity. PTT side connects to the wider group's petrochemical, downstream, and grid arms (GPSC, OR), giving Horizon Plus a structural pathway from manufacturing scrap to second-life ESS off-take inside the same parent. Strategic: scale, balance-sheet, and intra-group circularity. Expect BOI Section 8 applications in 2026-2027 for hydromet or hybrid lines paired with the manufacturing ramp.

Energy Absolute Amita Technology: EA's wholly-owned battery subsidiary operates the 1 GWh first-phase facility in Chachoengsao with a documented roadmap to 4 GWh. As both battery producer and downstream EV bus and boat operator, EA carries the highest captive-loop exposure of any Thai listed company. Strategic: vertical integration plus the SET-listed reporting requirement that forces transparent disclosure of EOL handling. Watch for the SET 56-1 footnote on EPR contingencies in FY2026 disclosure.

Global Power Synergy (GPSC) G-Cell and ESS arm: PTT group's G-Cell semi-solid-state prototype line and grid-scale ESS platform make GPSC the most-credible domestic off-taker for refurbished second-life NMC and LFP packs. Behind-the-meter, ancillary-services, and renewable-firming use cases are all in pilot; commercial rollout 2027-2028. Strategic: the cleanest pure-play ESS exposure within the PTT group structure.

SungEel HiTech Korea-Thai joint venture: Korea's largest hydrometallurgical battery recycler runs facilities in Korea, Hungary, and India. The 2025 ASEAN footprint review is actively scoping Thailand under BOI Section 8 to capture BYD Rayong, Foxconn-PTT, and EA scrap volumes. Strategic: deepest hydromet process IP plus the Korean OEM channel (Hyundai, Kia, LG Energy Solution-adjacent). Expect a formal Thai JV announcement in 2026-2027 if EPR enforcement signals firm.

GEM China-Thai joint venture: GEM is China's largest battery recycler with 40-plus GWh annual installed throughput, deeply tied to the CATL recycling arm for nickel and cobalt refining. ASEAN expansion is a stated 2025-2027 priority. Thai JV scoping has been disclosed in GEM 2025 annual filings; the entry vehicle would likely be a EEC-zoned hydromet plant paired with CATL battery supply downstream. Strategic: lowest unit cost on hydromet refining plus the China-Thai logistics corridor.

TES Singapore-Thai joint venture (SK Ecoplant subsidiary): TES runs Asia's most-established EV battery recycling network with the Singapore Tuas hub. Acquired by SK Ecoplant in 2022, TES brings the Korean balance sheet plus established Singapore-Indonesia-Malaysia collection logistics. Strategic: incumbent ASEAN reverse-logistics know-how plus a clean Western-OEM channel (TES collects for European and US automakers operating in Asia).

B.Grimm Power and EGCO Group: both run IPP and SPP capacity at scale plus active renewable-storage hybrid pilots. Neither operates its own battery recycling line, but both are credible off-takers for refurbished second-life ESS modules at behind-the-meter, grid-firming, and ancillary-services use. Strategic: utility-scale demand discipline that anchors second-life pricing floors. Watch for tendered ESS procurement that specifies second-life eligibility starting 2027.

Informal scrap dealers and aggregators: the Bangkok-Samut Prakan-Rayong informal scrap network plus lead-acid heritage recyclers historically captured the long tail of small-pack and motorbike battery flow. As PCD EPR enforcement bites in 2026-2027, this segment compresses materially: registered OEM take-back chains pull flow toward formal processors, and the long-tail aggregator role pivots toward collection-only sub-contracting for the BOI Section 8 anchors. Strategic risk for the segment, structural opportunity for formal processors.

Unit economics, route by route

NMC hydrometallurgical: industry-vintage economics put gross processing margin at roughly USD 2,500-4,500 per tonne of black-mass refined into nickel sulphate, cobalt sulphate, and lithium carbonate. At 2027 Thai cathode-metal pricing (modelled), a 10 GWh nameplate plant processing ~30,000 tonnes of EOL pack per year yields THB 2-4B in annual recovered metal value at the gate, with capex in the THB 6-10B range for a fully integrated hydromet line. Margin sensitivity is to nickel and cobalt LME pricing plus the lithium carbonate spot; Korean and Chinese operators run leaner than EU vintage.

LFP direct-recycling and cathode regeneration: lower nickel and cobalt content makes hydromet uneconomic, but direct-recycling and cathode regeneration preserves the cathode crystal structure for re-use at a higher unit margin. Process IP is earlier-stage; pilot economics suggest USD 1,500-3,000 per tonne. Strategic for Thailand because EV3.5-era LFP volumes from BYD, Foxconn-PTT, and GWM make this the higher-growth route post-2027. Capex roughly half of hydromet at equivalent throughput.

Second-life stationary ESS: refurbished NMC or LFP packs with 70-80% remaining capacity price into behind-the-meter and ancillary-services use cases at roughly USD 50-90 per kWh, versus USD 110-160 per kWh for new equivalent cells. Margin sits in the testing, balance-of-system integration, and warranty layer rather than the pack itself; integrators (PTT, GPSC, B.Grimm, EGCO, Solar D) capture the spread. Volume is the constraint, not demand.

Refurbishment for low-speed mobility: lowest-grade packs (50-65% remaining capacity) pivot to e-tuk-tuk, e-motorbike, and low-speed delivery vehicle conversions at USD 30-50 per kWh installed. Margin is thin; the volume play is informal-aggregator-driven and overlaps with the long-tail compression risk above. Mechanical pre-treatment and black-mass export remains the residual route, compressing as Basel Convention Annex VIII A1170 prior-informed-consent rules tighten transboundary movement.
