# OCI > OCI's disclosed circular-material lane is specific: recovered carbon black made from waste-plastic pyrolysis oil. The next decision is whether feedstock, certification and downstream grade requirements can stay aligned at commercial quality. - Industry: Chemicals & Advanced Materials - Collection: Active - Materials: Plastics - Processes: Recycling - Evidence through: 2026-09-18 - Canonical URL: https://www.materialtransition.com/library/oci ## Material inputs to resolve Advanced chemicals, basic chemicals, carbon chemicals and energy materials OCI's 2025 Integrated Report says recycled waste-vinyl oil from high-temperature pyrolysis is used in carbon-black manufacturing at its Gwangyang and Pohang plants, and reports 1,783 tons of recycled oil used in 2025. OCI says the carbon-black products maintain ISCC PLUS certification, and it identifies Saehan Recycle as the acquired source of pyrolysis oil from waste plastic film and packaging. Public sources do not disclose grade allocation, customer approval or a new offtake. **2024** Saehan Recycle acquisition disclosed **2 plants** Gwangyang and Pohang ISCC PLUS carbon-black certification disclosed **rCB** Recovered carbon-black grades from pyrolysis oil **Open** Feedstock, quality and customer qualification - Waste-plastic pyrolysis oil from Saehan Recycle - Chemical feedstocks and energy inputs - Certification, traceability and quality-control records ### Outputs and residuals to resolve - Recovered carbon black grades - Advanced chemicals and materials - Nonconforming feedstock and process residuals requiring controlled treatment **First decision:** Build one traceable carbon-black lane from waste-plastic input through pyrolysis oil, plant certification, grade specification and a named downstream application. ## Portfolio OCI identifies basic chemicals, carbon chemicals and energy solutions in its 2025 report. #### Circular asset The company says it is increasing recovered-carbon-black grades made from waste-plastic pyrolysis oil sourced from subsidiary Saehan Recycle. #### Certification evidence OCI says Gwangyang carbon black received ISCC PLUS certification in 2023 and Pohang carbon black in 2024. #### Evidence boundary The public record supports the asset, route and certification statements. It does not identify volume, batch performance, downstream customer or contracted supply. ### Decision boundary OCI has a real circular-material narrative only to the extent that waste-plastic pyrolysis oil, certification and recovered-carbon-black quality remain connected. Break that chain and the story becomes a claim. Keep it intact. ## Material flow map | Material or stream | Qualification gate | Process or destination | Evidence still needed | |-|-|-|-| | Waste plastic | Polymer mix, contamination and conversion yield | Saehan Recycle pyrolysis-oil route | Input acceptance, mass balance and yield | | Pyrolysis oil | Chemistry, traceability and certification scope | Carbon-black production | Plant allocation and process specification | | Recovered carbon black | Particle, structure, ash and application performance | Downstream rubber, plastic or other use | TDS, COA and buyer approval | This is a public screening map. It separates company-disclosed flows from open qualification work. It does not convert a destination into a buyer or an announced ambition into operating capacity. ## Three defensible entry lanes #### Trace the Saehan-to-carbon-black loop The disclosed subsidiary relationship gives this lane a specific physical starting point. **Next evidence:** Waste-plastic input criteria, pyrolysis yield, oil specification and transfer documentation. #### Use certification as a control, not a conclusion ISCC PLUS can support traceability, but it does not by itself establish application performance or commercial availability. **Next evidence:** Certificate scope, chain-of-custody method, product grade and batch records. #### Qualify one downstream grade Recovered carbon black succeeds only when it clears a real compound or product specification. **Next evidence:** TDS, COA, formulation trial, performance delta and customer approval. ## Evidence register - **OCI Integrated Report 2025** OCI https://www.oci.co.kr/esg/report [1] - **OCI Integrated Report 2025 PDF** OCI https://web-static.oci.co.kr/unity-report/content/2026/06/12/0473ca57-250b-4890-9fa1-9b4a87872218.pdf [2] - **Environmental Management disclosure** OCI Holdings https://web-static.oci-holdings.co.kr/unity-report/2025/08/20/0672e9d0-779b-4f20-834a-ff3818a9eecc.pdf [3] - **OCI Integrated Report 2025** OCI https://web-static.oci.co.kr/unity-report/2026/06/12/43551c12-c7e8-4f39-9044-9bcdbc76ccf5.pdf [4] - **OCI environmental management and ISCC PLUS** OCI https://www.oci.co.kr/en/esg/environmental [5] - **OCI 2025 ESG report hub** OCI https://www.oci.co.kr/esg/report [1] - **OCI Saehan Recycle acquisition presentation** OCI https://web-static.oci.co.kr/ir/2025/05/20/ffff8dc5-fd02-4ac3-9064-f35d25c8d081.pdf [6] Source hierarchy: filings and company disclosures first. The brief states what those sources support and leaves the unresolved plant, grade, permit, buyer and mass-balance questions explicit. ## Material Transition editorial interpretation The next useful working session starts with: Build one traceable carbon-black lane from waste-plastic input through pyrolysis oil, plant certification, grade specification and a named downstream application. ## Sources - [1] OCI Integrated Report 2025 - https://www.oci.co.kr/esg/report - [2] OCI Integrated Report 2025 PDF - https://web-static.oci.co.kr/unity-report/content/2026/06/12/0473ca57-250b-4890-9fa1-9b4a87872218.pdf - [3] Environmental Management disclosure - https://web-static.oci-holdings.co.kr/unity-report/2025/08/20/0672e9d0-779b-4f20-834a-ff3818a9eecc.pdf - [4] OCI Integrated Report 2025 - https://web-static.oci.co.kr/unity-report/2026/06/12/43551c12-c7e8-4f39-9044-9bcdbc76ccf5.pdf - [5] OCI environmental management and ISCC PLUS - https://www.oci.co.kr/en/esg/environmental - [6] OCI Saehan Recycle acquisition presentation - https://web-static.oci.co.kr/ir/2025/05/20/ffff8dc5-fd02-4ac3-9064-f35d25c8d081.pdf From the Material Transition company brief library: https://www.materialtransition.com/library/oci
