Low-Carbon DMT Opportunities Under Carbon Neutrality Goals: How Dimethyl Terephthalate Supply Chains Support Green Polyester Materials

TL;DR

• Against the backdrop of China's dual-carbon goals, circular-economy policy and recycled-material regulation, this article looks at the long-term value of low-carbon DMT, polyester-grade Dimethyl Terephthalate and green supply chains for PBT, PET and PETG applications.

Dual-Carbon Goals Are Pushing the Green Upgrade Upstream

As carbon-neutrality targets and circular-economy policy continue to advance, low-carbon feedstock is shifting from an ESG talking point to a genuine purchasing requirement. For polyester materials producers, the carbon footprint, supply stability and quality documentation of upstream monomers — DMT, PTA, EG — now feed directly into how downstream products are assessed and how they fare in brand-customer audits.

Background to the proposal

• China generates over 60 million tonnes of waste plastic a year, the highest volume globally
• Mechanical recycling is approaching its ceiling; chemical recycling is the route to a genuine closed loop
• Europe, the US and Japan have already commercialised chemical recycling; China needs to move faster
• Chemical recycling of waste plastics carries 100–200 million tonnes of carbon reduction potential

Five Dimensions Shaping the Low-Carbon DMT Industry

1. Strengthen top-level design with a dedicated plan

The proposal calls for national and industry-level planning around low-carbon feedstock, recycled materials and green supply chains — with explicit development targets, quality standards and certification pathways for high-quality polyester feedstock.

• An industry roadmap for 2025–2035
• A 5 million tonne chemical-recycling throughput target by 2030
• Inclusion of chemical recycling in the 14th Five-Year Plan circular-economy programme

2. Increase R&D investment

The proposal recommends a dedicated national key R&D programme covering low-carbon production of key polyester monomers such as DMT and EG, catalyst development, purification processes, domestic equipment manufacture and analytical methods.

• A dedicated R&D fund of no less than RMB 5 billion
• Support for 3–5 national innovation centres
• Policy support for first-of-type major technical equipment
• Deeper technical cooperation with international leaders

3. Complete the policy support framework

Fiscal, tax and financial measures are proposed for chemical-recycling companies, including VAT refund-upon-collection, income tax relief and green credit support.

• VAT: 80% refund upon collection
• Corporate income tax: exempt for the first three years, halved for the following three
• Green credit: interest rates 20% below benchmark
• Carbon market: priority inclusion in CCER

4. Build out the standards system

National, industry and association standards for green polyester feedstock are to be accelerated, covering DMT purity, impurities, carbon footprint, COA/MSDS and batch traceability requirements.

• Twenty or more national standards
• A certification system for chemically recycled products
• Full-lifecycle traceability for products
• Mutual recognition with international standards

5. Raise awareness

Broader communication of why chemical recycling matters, to build understanding and participation across society and cultivate a green consumer market.

• Public science communication campaigns
• Recognition of benchmark companies and demonstration projects
• Promotion of green procurement and green consumption
• Stronger international exchange and cooperation

Significance and Expected Impact

The proposal by CPPCC member Li Jinghong drew broad support from fellow delegates, with several co-signing. It is expected to advance the following:

• MIIT to include chemical recycling among 14th Five-Year Plan priority tasks
• NDRC to develop dedicated support policies
• MOST to launch a national key R&D programme
• An estimated RMB 100 billion+ in mobilised social investment

The ResourceCycle View: Policy Opportunity Still Resolves to Supply Capability

Dual-carbon policy provides a durable demand base for low-carbon DMT, but customers buy on verifiable product capability. ResourceCycle's focus stays where purchasing decisions are actually made: high-purity Dimethyl Terephthalate, ethylene glycol co-production, COA/MSDS documentation, batch traceability and customised delivery for PBT, PET, PETG and specialty polyester customers sourcing green feedstock.
