Recycled Plastic Garment Trims
Turn Bangladesh's garment-industry plastic scrap into certified recycled buttons and trims sold back to RMG factories.

The ask
Set up a recycled-plastic button and trims manufacturing unit that collects plastic scrap from garment factories, processes it into certified recycled resin, and moulds it into buttons, snap fasteners, and hangtag loops — sold back to the same RMG factories for their sustainability compliance needs.
Why now
Europe's Ecodesign for Sustainable Products Regulation (ESPR), applying to textiles from 2026, requires manufacturers to document recycled content in trims and accessories. Bangladesh's top 10 export buyers — H&M, Zara, PVH, Primark — have committed to 100% sustainable sourcing by 2030; trims are a visible, auditable component. Currently, Bangladesh imports almost all its buttons from China; a domestic certified-recycled supplier can offer shorter lead times, a sustainability certificate, and competitive pricing simultaneously.
Why Bangladesh
Bangladesh's 4,500 RMG factories generate roughly 500,000 tonnes of plastic scrap per year — polybags, thread cones, bobbin holders, packaging film — much of which is currently burned or landfilled within factory compounds. This is a zero-cost feedstock within 15 km of Gazipur and Ashulia, where most garment factories cluster. The country already has a substantial plastics processing industry; button moulding equipment is standard injection-moulding technology, widely available and locally serviceable.
As a business
Sell certified-recycled buttons at ৳0.80–1.50 per button against imported Chinese buttons at ৳0.60–1.20 — the premium is justified and paid by buyers requiring the GRS (Global Recycled Standard) certificate. Volume is the key: at 2 million buttons/day, monthly revenue is ৳50–90 million. Secondary revenue is selling recycled resin pellets (GRS-certified) to other plastics moulders — a B2B wholesale stream that absorbs excess processing capacity and doesn't require the tooling investment of finished goods.
Economics
Move the sliders to model your own recycled trims business. Defaults are order-of-magnitude estimates — pressure-testing them is part of what a founder pitches us.

What ZEPH would back
A founder with garment supply chain experience who has already secured GRS certification or is actively in the process, and who has a committed sample order from one mid-tier export factory. The moat is the GRS certificate and the factory-gate feedstock agreements — both take 6–12 months to establish and are genuinely difficult to replicate quickly. We'd expect this company to be cash-flow-positive within 18 months of launch.
Impact
Bangladesh's 4,500 RMG factories generate ~500,000 tonnes of plastic scrap annually, most burned or landfilled; converting even 1% into certified buttons and trims avoids roughly 15,000 t CO₂e/year versus virgin polystyrene/ABS button production (~3 kg CO₂e/kg). The business simultaneously substitutes a near-100% imported input — Bangladesh imports virtually all buttons from China — saving an estimated $80–120 million/year in hard currency at scale. EU Ecodesign and ESPR regulations from 2026 make certified recycled trims a compliance requirement rather than an option for top-10 apparel buyers, creating a pull market with structural demand.
