Voluntary Disclosure Statement
This document is a voluntary disclosure by the producer (Corsair Bangkok Company Limited) to provide sustainability-related information about its product. It does not constitute an endorsement or certification by any United Nations (UN) agency or regulatory authority. All information is presented with transparency, accuracy, and traceability.
Basic Information
- Company: Corsair Bangkok Company Limited
- Factory Location: Nonthaburi, Thailand
- Product: Circular Pyrolysis Oil
- Certification: ISCC PLUS (2022–2025), category: Circular raw materials (waste plastic → circular oil)
Corsair Bangkok represents a strategic case of circular feedstock designed from the buyer’s perspective. Instead of converting plastic waste into fuel, it produces only pyrolysis oil suitable for reintegration into the polymer supply chain. Its system ensures upstream quality control, consistent product specifications, and full traceability. All data are structured to support Scope 3 accounting and ESG disclosures in alignment with CSRD, without imposing additional verification burdens on the buyer. As a result, buyers benefit from measurable GHG reductions from fossil substitution, enhanced regulatory legitimacy, and streamlined ESG compliance. Corsair Bangkok thus serves as a strategic supplier for purchasers seeking evidence-based, internationally verifiable sustainability.
Role of the Product in the Circular Economy

Corsair Bangkok’s pyrolysis oil is specifically engineered for reintegration into the polymer production cycle—not for combustion or energy recovery. This positioning aligns with the principles of Sustainable Consumption and Production (SCP) under the United Nations framework, as well as the OECD’s “do no harm across systems” approach.
- The oil is produced from mixed plastic waste from post-consumer sources.
- It is processed and qualified for use as polymer feedstock under a mass balance framework, suitable for integration into established cracker infrastructure.
- Corsair Bangkok explicitly states that the product is not fuel-grade, and it is not offered or designed for fuel or energy applications.
This role clarity enhances transparency and strengthens its alignment with circular economy policy expectations, particularly for downstream buyers seeking credible and verifiable sustainability performance.
Sustainability Benefits for Buyers
Virgin Plastic Reduction
- ISCC PLUS certified from 2022 to 2025; input = mixed plastic waste, output = circular oil
- Mass balance chain of custody available
- Scope 3 and GHG data available for reporting
GHG Emissions Reduction
- Independent Intertek analysis confirms sulfur and nitrogen below 0.1 wt%
- Aromatic/heavy fraction <5%, suitable for polymer-grade use
Plastic Leakage Reduction
- Traceability and pre-screening system: feedstock → process → product
- Designed to meet polymer producers’ chlorine and heavy metal thresholds
Buyer Reporting Alignment (FTSE Russell / GRI / CSRD)
| Reporting Area | Readiness Status |
| GHG Scope 3 (Purchased goods) | Emission factors and mass balance data available |
| Resource use (GRI 301) | Plastic waste input → circular oil output; declared conversion ratio |
| Circularity metrics | Mass balance and traceability documentation included |
| Environmental compliance | Aligned with ISCC PLUS framework and applicable environmental regulations and industry standards |
| UN SDG linkage | Non-claiming narrative linking to SDG 12, 13 |
Areas Needing Further Development — Guidance for Buyers
While Corsair Bangkok’s pyrolysis oil shows strong alignment with the principles of circular economy and SCP, buyers should be aware of specific areas where further verification and certification would enhance reporting confidence under global disclosure standards:
- No third-party ISO 14067 Product Carbon Footprint (PCF) available
- No ISO 14064-3 third-party verification of GHG statements
Recommendation to Buyers:
In the interim, Corsair’s current documentation—including ISCC PLUS certification, material use declarations, and traceability records—provides a credible foundation for ESG disclosures, GHG inventory reporting (e.g., Scope 3), and CSRD-aligned materiality assessments. Buyers are advised to include clarifying notes in sustainability reports regarding the status of third-party verifications, and may consider entering structured collaboration with Corsair to pursue progressive assurance milestones over time.

Remark
This disclosure is made on a voluntary basis to enhance transparency and support informed decision-making for buyers and stakeholders. If any information presented herein is suspected to constitute greenwashing or may be misleading, stakeholders are encouraged to submit verifiable evidence to: whistleblower@stnsm.org.
