In late August 2026 the Shandong Provincial Administration for Market Regulation and the Shandong Provincial Development and Reform Commission issued the 2026 Provincial Standardization Pilot Program (Green Low-Carbon Field) (鲁市监标字〔2026〕168号, dated 28 Aug 2026). On 21 September 2026 the Jining municipal counterparts forwarded it to Wenshang County under 济市监函〔2026〕46号, naming the undertaking: the Jining Wansheng Environmental PET Solid Waste Recycling Standardization Pilot (济宁万生环保PET固废循环利用标准化试点), the DOTP line run by our wholly-owned subsidiary Jining Wansheng Environmental Materials Co., Ltd. in the Wenshang Chemical Industrial Park, where waste PET becomes plasticizer.
Ten projects were approved across Shandong. Ours is number six on the list, and the only one built around waste plastics and plastic additives. The pilot runs through 2027–2028, with every task to be completed before the end of 2028.
Key Takeaways
- ✅ Wansheng's PET solid-waste recycling model was selected as one of 10 Shandong provincial standardization pilots (green low-carbon field) for 2026, under notices 鲁市监标字〔2026〕168号 and 济市监函〔2026〕46号
- ✅ It is the only plastics-recycling project on the list; the other nine cover zero-carbon parks and an island, coal gangue, thermal storage, retired lithium batteries, shipbuilding, metallurgy and pre-baked anodes
- ✅ Selection ran through local recommendation, expert review and a public comment period. The program implements the National Standardization Development Outline and puts the 15th Five-Year Carbon Peaking Action Plan into effect
- ✅ Deliverables are a standard system for PET solid-waste recycling: implementation plan, replicable working model, and standard proposals that can be promoted across the whole industry by end-2028
- ✅ Regulators will not run supervision, assessment or acceptance inspections during the pilot; a self-assessment report is filed after the term ends, then reviewed at provincial level
What the Two Notices Decide
The provincial notice is short and procedural; the municipal forwarding letter adds the local accountability chain. Read together, they set four things in motion.
- Who is on the hook. Wenshang County's market regulation and development-and-reform bureaus must coordinate and guide the undertaking entity (that is, Wansheng), which in turn drafts its own implementation plan against the pilot tasks.
- What counts as success. Not a certificate on a wall. The stated output is a set of standards: explore how standards are drafted and applied in this field, improve the relevant standard system, distil a replicable and scalable working model, and produce high-level standards.
- When. A two-year cycle covering 2027 and 2028, closing before 31 December 2028.
- How it is policed. Deliberately lightly. Both notices repeat that no supervision, assessment or acceptance inspection may be organized during the pilot, so the company can work without audit traffic. Verification happens once, after the term, through a self-assessment report escalated from county to city to province.
One of Ten: The 2026 Shandong Green Low-Carbon Pilots
The attachment to the provincial notice lists every approved project, its undertaking entity and the municipal bureau that nominated it. Context matters here: eight of the ten are industrial parks, marine zones or heavy-industry groups, and several are state-invested. A plastic-additives producer sits on this list because its core process is recycling.

What the Pilot Must Produce by End-2028
The program brief asks for work at three levels, and each one has a buyer-facing consequence.
- A standard system for PET solid-waste recycling. Written rules for how incoming waste PET is classified, accepted, tested and traced through to the finished plasticizer, which is the paperwork chain that today varies from converter to converter.
- Standard proposals usable by the whole industry. The notice explicitly asks pilot enterprises to mine proposals that can be promoted beyond their own gates, i.e. contribution to sector-level standards rather than a private specification.
- A replicable working model. The combination of feedstock handling, esterification process control and documentation that another plant could copy. That is the test of whether a recycling claim can be audited at all.
"Explore experience in developing and applying standards, formulate and improve the relevant standard system, form a replicable and scalable standardization working model, and produce high-level standards."
Why Recycled-Content DOTP Buyers Should Care
Most plasticizer purchase decisions are still made on price, colour, acid value and lead time. Recycled content is where the conversation has been heading, and it is where documentation is thinnest. A brand that asks its compounder for verified recycled content usually receives an assertion, not a method.
A provincial standardization pilot is precisely a method-building exercise. Three practical effects for procurement:
- Auditable feedstock claims. Chemical recycling from waste PET only means something if the input stream is classified and recorded consistently. That is the first thing the pilot systematizes.
- Comparable specifications. Standards written at provincial and industry level give buyers a reference to test suppliers against, instead of accepting each supplier's internal data sheet on trust.
- Compliance already demonstrated at product level. Standardization of process does not replace product testing. Our DOTP has already passed SGS screening for 17 phthalates, EN 71-3 element migration and PFAS total fluorine, all non-detectable.
The Recycled PET to DOTP Operation Behind the Nomination
Wansheng converts waste PET (post-industrial polyester scrap, baled textile waste and recovered flake) into DOTP through catalytic esterification and transesterification, on a 150,000-ton-per-year line in the Wenshang Chemical Industrial Park. The nominated project is not a laboratory scheme; it formalizes a process already running at commercial scale, which is also why the county bureau could recommend it.
Both plants operate under the group's ISO 9001, ISO 14001, ISO 45001 and ISO 50001 certified management systems. The parent company, Shandong Changxing Plastic Additives Co., Ltd., is a national high-tech enterprise and a Shandong specialized-and-innovative (专精特新) manufacturer, and the DOTP it ships has cleared SGS screening for 17 phthalates, EN 71-3 element migration and PFAS total fluorine.

Frequently Asked Questions
What exactly was selected, and by whom?
The "Jining Wansheng Environmental PET Solid Waste Recycling Standardization Pilot" was included in the 2026 Shandong provincial standardization pilot program (green low-carbon field), issued by the Shandong Provincial Administration for Market Regulation and the Shandong Provincial Development and Reform Commission under 鲁市监标字〔2026〕168号 on 28 August 2026. It is item 6 of 10 approved projects. The undertaking entity is Jining Wansheng Environmental Materials Co., Ltd.
How does a company get onto this list?
Three stages, per the provincial notice: local recommendation (here, by the Jining Administration for Market Regulation), expert argumentation, and a public comment period. The program implements the National Standardization Development Outline and puts the 15th Five-Year Carbon Peaking Action Plan into effect.
Does the pilot change the DOTP we buy today?
No. Product specifications, testing and certification are unchanged and continue to be delivered against our existing quality system. The pilot targets process documentation and standards: how waste PET feedstock is classified, accepted, traced and converted. Over 2027–2028 that produces a more auditable recycled-content story, not a different molecule.
What else is on the 2026 list?
Nine other projects: zero-carbon park and zero-carbon island pilots (Jinan Shanghe, Changdao), a low-carbon chemical park (Dongying District), coordinated power and heat storage recycling (Qingdao), coal gangue utilization (Zibo), retired lithium-battery recycling (Tai'an), full-lifecycle green shipbuilding (Weihai), full-process low-carbon metallurgy (Linyi), and pre-baked anode carbon-emission management (Dezhou). Wansheng's is the only waste-plastics recycling entry.
When is the pilot completed, and who checks it?
The cycle is 2027–2028 and all tasks must be finished before the end of 2028. During the pilot, market regulation and development-and-reform departments at every level are barred from organizing supervision, assessment or acceptance inspections. After the term, the company prepares a self-assessment report with the county bureaus; it is reviewed by the Jining municipal authorities and re-checked by the provincial departments.
