Programme overview
Introduction:
Sustainable polymers and plastics recycling now shape resin demand: brand owners ask producers for recycled content, packaging fees reward recyclable design and investors question the carbon footprint of virgin polyolefins. Yet many petrochemical and converter teams cannot say which recycling route suits which waste stream, what quality a recyclate can reach or how a mass-balance claim is verified. This Core Concept course links mechanical and chemical recycling, bio-based feedstocks, chain-of-custody bookkeeping, eco-design and footprint data to commercial decisions. Participants build a Circular Polymer Product Strategy for a case producer.
Course Objectives:
- Map the plastics value chain from monomer to post-consumer bale and locate where material and value leak out of the loop
- Assess mechanical recycling steps and the quality limits of recyclate for food-contact, film and rigid applications
- Compare pyrolysis, depolymerisation, solvolysis and gasification routes by feedstock tolerance, yield, product use and cost
- Specify recycled-content and bio-based polyolefin grades and verify content claims under mass-balance chain-of-custody rules
- Evaluate packaging designs for recyclability, producer-fee exposure and life cycle carbon footprint
- Build a Circular Polymer Product Strategy with feedstock sourcing, grade portfolio, economics and claims plan
Target Audience:
- Commercial and product-management staff at polyolefin and PET producers who shape recycled and bio-attributed grade offers
- Technical service and application development staff who qualify recyclate grades with converters and brand owners
- Converter and packaging development staff who redesign films, bottles and rigid packs for recyclability
- Sustainability and product stewardship staff who compile footprint data and substantiate recycled-content claims
- Feedstock, procurement and business development staff who source bales, pyrolysis oil or bio-based inputs

Skills You Will Gain:
- Polymer Value Chain Mapping
- Recyclate Quality Assessment
- Recycling Route Selection
- Recycled Grade Specification
- Chain-of-Custody Verification
- Recyclability Design Review
- Polymer Footprint Comparison
- Circular Polymer Business Case Building
Why Attend This Course:
- Return with a Circular Polymer Product Strategy built on case producer data and tested before a management panel
- Answer customer requests for recycled or bio-attributed grades with specifications and claims you can substantiate
- Judge vendor promises on pyrolysis, depolymerisation and bioplastics against feedstock, yield and footprint evidence
- Compare circular polymer practice with peers from petrochemicals, converting, packaging and consumer goods
Conclusion:
Circular polymers depend on matching each waste stream to a recycling route, turning recyclate or attributed feedstock into grades customers can use and backing every claim with bookkeeping and footprint data. The week moves from the plastics value chain and material leakage, through mechanical and chemical recycling routes, to recycled-content and bio-based grades and mass balance, then to recyclable design, producer fees and life cycle carbon. The final day turns a case producer's data into a Circular Polymer Product Strategy ready for management review.
