What is closed-loop plastic recycling?

Closed-loop recycling means capturing the industrial waste generated during manufacturing (such as runners, sprues, and off-spec parts), grinding it down, and mixing it back in with virgin resin to mold new parts for the exact same product line.

Does using regrind affect part strength?

It depends on the polymer and the percentage used. Every time plastic is melted and cooled, its polymer chains shorten slightly, which can reduce tensile strength. For structural parts, we typically cap regrind at 15-20% mixed with virgin resin. For non-structural parts, up to 100% regrind can be used.

How does this help with ESG compliance?

UK and EU regulations increasingly mandate a minimum percentage of recycled content in plastic packaging and components. By implementing a closed-loop regrind program at the factory level, you automatically meet these mandates without relying on third-party post-consumer recycled (PCR) resin suppliers.

The Closed-Loop Advantage

In traditional manufacturing, the "runners" and "sprues" (the plastic that solidifies in the channels leading to the mold cavity) are discarded as waste. In vacuum forming, the skeletal waste left after trimming can account for up to 30% of the original plastic sheet.

As a global custom molding company, we operate a zero-waste floor policy. We capture this post-industrial waste at the machine level, feed it into heavy-duty granulators, and process it into uniform "regrind" pellets.

This regrind is then blended back into the hopper with virgin resin at a strictly controlled ratio (typically 10% to 25%). The result? The exact same part quality, but with a significantly lower raw material cost and a drastically reduced carbon footprint.

Navigating EU and UK ESG Mandates

Environmental, Social, and Governance (ESG) compliance is no longer optional for Western brands. The UK Plastic Packaging Tax (PPT) and the EU's Circular Economy Action Plan impose severe financial penalties on products that do not contain a minimum of 30% recycled content.

By utilizing our closed-loop recycling program, your supply chain automatically meets these mandates. Because we are recycling your own post-industrial waste (rather than sourcing unknown post-consumer recycled resin from the open market), we can guarantee the material's purity, mechanical properties, and RoHS/REACH compliance.

Core/Cap Co-Extrusion

For clients utilizing our plastic profile extrusion capabilities, we offer "Core/Cap" manufacturing. We extrude the hidden inner core of the profile using 100% recycled PVC regrind, and then cap the visible exterior with a thin layer of virgin, UV-stabilized polymer. This maximizes ESG compliance and cost savings without sacrificing the Class-A surface finish.
