Sustainability and compliance

ESG data, restricted substance review, and practical documentation discipline.

Westlake approaches sustainability in a way that fits B2B plastic product sourcing: measurable claims, clear document ownership, and realistic material discussions. Buyers in packaging, construction, consumer goods, and industrial manufacturing face different sustainability pressures, but many share the same operational problem. They must answer customer questions about recycled content, food-contact suitability, restricted substances, regional regulations, and material traceability while still keeping supply and cost under control.

The sustainability workflow therefore begins with the claim the buyer needs to make. A PCR target, REACH statement, RoHS declaration, FDA food-contact note, or restricted substance confirmation each requires different data. Westlake helps organize those requests before quotation so the commercial offer does not drift away from the approval package that will be needed later.

ESG table

Common data fields for responsible plastic sourcing.

TopicBuyer questionWestlake intake data
Recycled contentCan the program support PCR or recycled material targets?Target percentage, product contact, performance limits, labeling expectation
Restricted substancesWhich declaration is required for the destination market?REACH, RoHS, Prop 65, PFAS screening context, customer list
Food contactWill packaging or components touch food, beverage, or pharma products?Material family, contact condition, temperature, region, migration context
TraceabilityHow should lots, samples, and documents be linked?Batch reference, sample labels, shipment site, document owner, approval route

Certification checklist

Documents frequently requested in polymer and plastic product programs.

REACH SVHC communication

Useful when materials or finished products move into European customer channels or global OEM reporting systems.

RoHS 3 declaration

Important for plastic components used around electronics, assemblies, appliances, and export-oriented finished goods.

FDA 21 CFR food-contact context

Relevant for packaging, containers, closures, films, and materials that may contact food or beverage products.

PCR and recycled content notes

Needed when brand-owner targets require stated recycled content ranges, limitations, and product-use boundaries.

Responsible plastic sourcing is not only a material choice. It is a documentation process. A buyer may want a lower-carbon resin or a recycled-content package, but the final approval still depends on performance, availability, compliance claims, customer language, and cost. Westlake's role is to keep these threads connected. If a recycled option changes clarity, impact strength, odor, process behavior, or food-contact suitability, that tradeoff should be visible before a trial. If a customer needs a restricted substance declaration, the scope and destination market should be stated before the quote is finalized. This keeps sustainability work grounded in decisions that procurement and engineering can support.

Make the required claim clear before the material is quoted.

Westlake can align sustainability notes, compliance data, and product fit in the same RFQ review.
