ResourceCycle deployed a mobile skid-mounted DMT chemical-recycling unit for a south China BOPET film manufacturer, processing 500 t/y trim waste with 100% in-line resource utilization, +¥2.2M/y new economic benefit, and 60% capex vs traditional fixed unit.
The client is a south China BOPET specialist producing optical, electronic, and release films. BOPET process characteristics generate continuous trim, ignition and broken-film waste — ~500 t/y total — historically sold to downstream recyclers at ¥4,800/t, with under-realized value.
As optical-grade BOPET tightens raw material consistency requirements, recycler-sourced secondary material no longer meets in-line reuse. Concurrently, brand customers (display panel, EV manufacturers) raise raw material carbon footprint and traceability demands. The client needed in-line regeneration + closed-loop reuse capability.
After evaluating 4 chemical-recycling vendors, the client selected ResourceCycle’s mobile skid solution — per-ton capex 60% of fixed-installation alternatives (¥18,000/t capacity vs ¥30,000/t), and deployable physically adjacent to existing BOPET line, with ≤50 m logistics radius.
ResourceCycle 500 t/y mobile skid DMT unit — disassembled into 4 × 20 ft container loads, on-site assembly ≤5 days. Per-ton capex ¥18,000 — only 60% of fixed unit.
Unit on 280 m² fringe space beside BOPET line; waste enters pre-treatment via 30 m conveyor, ≤50 m logistics radius — eliminates external transport.
Tailored deep decolorization + deacidification: 4-stage distillation + activated carbon + molecular sieves. DMT product b ≤0.3, color ≤3 APHA, purity ≥99.95% — exceeds general polyester grade.
DMT routed in insulated piping at 145-150°C liquid state directly to BOPET reactor feed inlet — avoids reheating energy. DCS integrated with client master control system.
ResourceCycle + SGS completed full PCF chain audit: trim collection → chemical recycling → DMT product → BOPET reuse. ISO 14067 report provided to client for brand customer submission.

| Capex per ton capacity | ¥18,000/t | 40% lower than fixed unit |
| Logistics radius | ≤50 m | In-line conveyor only |
| Trim value uplift | +¥4,000/t | From recycler outbound to in-line feedstock |
| Annual new economic benefit | ~¥2.2M | Feedstock substitution + value uplift |
| Optical-grade DMT validation | Passed | b ≤0.3, haze ≤0.5% |
| Static payback | 4.2 years | Includes skid equipment + installation |
| BOPET carbon reduction | -18% | PCF report delivered to brand customers |
「What we valued most wasn't the recovery rate number — it was ResourceCycle's skid solution that let us complete 'trim waste → optical-grade feedstock' value uplift without stopping production or expanding the site. First batch DMT b = 0.27 — more stable than the imported secondary recycled material we used to buy.」
