Polyethylene terephthalate (PET) is the clear, lightweight plastic used for many bottles, jars and preforms. rPET is PET that has been collected after use, sorted, cleaned, and reprocessed into new resin. When brands specify rPET, they replace some or all virgin PET with recycled content—ideally in a closed loop (bottle-to-bottle) rather than down-cycling.
Collection & sorting of used PET.
Preparation: removal of labels/caps; PET is flaked and washed.
Decontamination & pelletising to create high-quality rPET resin.
Conversion: rPET pellets are moulded into new preforms and containers, including food-grade applications where processes meet regulatory standards.
Design choices such as using clear PET and recycling-friendly labels help this loop work efficiently.

1) Lower carbon and energy use
Switching a pack from virgin PET to rPET typically reduces lifecycle greenhouse gas emissions and energy demand. The exact saving depends on system boundaries, recycled content level and logistics, but the direction of travel is consistently favourable.
2) UK compliance and cost control
In the UK, plastic packaging containing less than 30% recycled plastic is liable for the Plastic Packaging Tax. Setting ≥30% rPET as a baseline for eligible SKUs helps manage exposure while demonstrating progress on recycled content targets.
3) Measurable progress on ESG and Scope 3
Recycled content contributes to Scope 3 (Purchased Goods & Services) reductions and supports circular economy commitments. Using rPET alongside clear on-pack recycling instructions strengthens both corporate reporting and consumer trust.
4) Performance you can specify
rPET retains PET’s strengths: clarity, impact resistance and light weighting. High-rPET contents are now routine in many beverage, personal-care and household formats, subject to validation of colour, haze and product compatibility.
5) A clearer story for customers and retailers
“Made with recycled plastic” claims, backed by verifiable percentages and robust design-for-recycling, are easy to communicate and align with retailer sustainability requirements.
Material selection is application-specific. For many beverage and personal-care uses, PET’s low weight and efficient conversion can provide a lower overall footprint than heavier alternatives—particularly as rPET content increases. Always compare like-for-like using your actual volumes, distances and energy mix.
rPET offers a straightforward route to reduce packaging emissions, support circularity and meet UK regulatory expectations while preserving the performance that brands and consumers expect. Set a minimum recycled-content specification, design for recyclability from the outset, and increase rPET levels as supply and aesthetics allow.
