Buyer's Guide
Recycled resin, answered.
Everything procurement teams ask us about buying recycled plastic — certifications, pricing, quality, regulation and logistics. Straight answers, no jargon.
The basics
What's the difference between PCR, ocean-bound and ocean plastic?
Post-consumer recycled (PCR) is any plastic recovered after consumer use. Ocean-bound plastic is collected within 50km of a coastline in areas without formal waste management — stopped before it reaches the sea. Ocean plastic has already been in the water. Most high-quality resin on the market is PCR or ocean-bound; true ocean plastic is usually too degraded for demanding applications.
Is recycled resin really a like-for-like replacement for virgin polymer?
For most applications, yes — with the right grade. Modern rHDPE, rPP and rPET run on standard lines with little or no adjustment. The key is matching MFI, density and contamination limits to your process. That's why every batch should ship with a Material Test Report, and why you should always trial a sample on your own line first.
What do MFI and density numbers actually tell me?
Melt Flow Index (MFI) tells you how the resin flows when melted — low MFI suits blow moulding and extrusion, high MFI suits injection moulding. Density affects stiffness and weight. If a supplier can't state MFI and density per batch with lab data behind it, that's a red flag.
Certification & compliance
What is GRS certification and why does it matter?
The Global Recycled Standard (GRS) is the leading third-party certification for recycled content. It verifies the recycled claim and tracks chain of custody from recycler to finished resin. For buyers it means your recycled-content claims are auditable — essential for EU packaging regulation, plastic taxes and brand claims.
Can recycled plastic be food-grade?
Yes. rPET is widely approved for food contact (EFSA in the EU, FDA in the US), and food-grade rHDPE and rPP are available from certified processes. Always ask for the specific compliance documents — e.g. Commission Regulation (EU) No 10/2011 or FDA 21 CFR — per batch, not just a general claim.
How do recycled-content rules like EU PPWR affect me?
The EU Packaging & Packaging Waste Regulation sets mandatory recycled-content targets for plastic packaging from 2030, and several countries already tax packaging with low recycled content. Buying certified resin with per-batch chain-of-custody documentation is how you evidence compliance — uncertified 'recycled' material may not count.
Quality & risk
What contamination levels are acceptable?
It depends on your application — food contact and thin-wall products need the tightest specs. Agree contamination, moisture and colour limits in writing before ordering, and make sure every shipment is tested against that spec. A serious supplier will replace or refund out-of-spec material as standard.
How do I evaluate a recycled resin supplier?
Ask five things: Can they show GRS or equivalent certification with chain of custody? Do they provide a Material Test Report per batch? Can they name the source and process of the material? What happens if material arrives out of spec? And can you visit or audit the operation? Good suppliers answer all five without hesitation.
Can I blend recycled resin with virgin material?
Yes — blending is the most common way to adopt recycled content while protecting tight process windows. Many buyers start at 25–50% recycled and increase as they validate performance. Your recycled-content claim then reflects the blend ratio, backed by the certified tonnage you purchased.
Buying & logistics
How is recycled resin priced compared to virgin?
Recycled resin pricing moves partly with virgin polymer markets and partly with recovered-material supply. Depending on grade and market conditions it can price below, at, or above virgin. Buyers increasingly value price stability, certification and regulatory compliance over chasing the lowest spot price.
What are typical MOQs and lead times in this market?
MOQs commonly run 5–25 tonnes for first orders. Lead times from Southeast Asian supply chains to Europe are typically 4–8 weeks; buying from European stock (like our Antwerp warehouse) cuts that to days for samples and short lead times for bulk.
Should I trial a sample before committing to bulk?
Always. A 2.5–5kg sample run on your own line tells you more than any datasheet. Check processing behaviour, colour consistency and finished-part performance — then scale with confidence knowing each bulk batch is tested against the same spec.
