With the official release and implementation of GB/T 45441-2025 – Greenhouse Gases: Quantification Methods and Requirements for Product Carbon Footprint of Plastic Products, China’s plastics industry has entered a new era of standardized, transparent, and measurable carbon footprint management.
This national standard provides a scientific measurement framework to support China’s “Dual Carbon” goals and clearly defines the pathway for green transformation across the materials industry.
As a long-term specialist in high-performance BMC (Bulk Molding Compound) composites, Wenzhou Jintong Complete Electrical Co., Ltd. (Jintong) has proactively aligned its R&D and manufacturing systems with this standard. By integrating carbon footprint management into the entire product lifecycle, we are systematically advancing the development of low-carbon BMC materials, delivering quantifiable and verifiable green material solutions for customers in electrical equipment, automotive, rail transit, and new energy industries.
At the core of GB/T 45441-2025 is a Life Cycle Assessment (LCA) methodology, establishing a unified and rigorous benchmark for plastic product carbon footprint accounting.
Guided by this framework, Jintong has built a “cradle-to-gate” carbon management system for BMC materials.
Clearly defined system boundaries
Our carbon footprint calculations strictly cover raw material acquisition, internal production processes, energy consumption, and pre-delivery storage and transportation—ensuring completeness and compliance with national standards.
Data quality as a priority
Beyond using industry-average emission factor databases, we actively collaborate with key resin and filler suppliers to obtain primary activity data, significantly improving the accuracy and credibility of upstream carbon calculations.
Full transparency and traceability
From formulation batch records to real-time energy monitoring on the production floor, Jintong has established a complete data collection and traceability system. Every carbon footprint result is backed by reliable, auditable data—fully meeting the standard’s requirements for transparency and consistency.
Jintong’s low-carbon BMC strategy goes far beyond conceptual claims. It is embedded in practical innovation across the entire material lifecycle.
Renewable and recycled mineral fillers
While maintaining key performance indicators such as flexural strength and electrical insulation, we actively apply mineral fillers derived from industrial by-products to reduce dependence on virgin resources and lower embedded carbon.
High-performance co-design
By optimizing formulations to meet UL94 V-0 flame retardancy and CTI ≥ 600V, we precisely control material density and usage, indirectly reducing carbon emissions per unit.
Next-generation low-carbon BMC development
We are currently developing a new BMC 17 Series, integrating low-carbon design principles while preserving outstanding mechanical and electrical performance. This next-generation material is designed to deliver an even lower carbon footprint and will be introduced to the market in the near future.
Lean process optimization
Leveraging our integrated material–mold–process control capability, we precisely manage mold temperature uniformity (±5°C) and pressure curves, significantly improving first-pass yield and reducing energy consumption and scrap rates.
Energy-efficient equipment and clean energy planning
Continuous energy-saving upgrades in kneading and compression molding equipment are underway, alongside future plans to introduce renewable electricity to further reduce manufacturing carbon intensity.
Standard-compliant carbon footprint reports
We provide product-level carbon footprint reports for specific BMC grades or customized parts, supporting customers’ green certifications, export compliance, and ESG disclosures.
Promoting “plastic-for-metal” lightweight solutions
By replacing aluminum or steel with BMC in applications such as motor terminal boards, automotive components, and cable supports, weight reductions of 30–60% can be achieved—delivering significant energy and emission savings during the product use phase.
Accurate carbon footprint quantification transforms Jintong’s environmental efforts into tangible market value:
Regulatory compliance and market access
Our low-carbon BMC solutions help customers address evolving carbon regulations, including EU CBAM and domestic green procurement requirements.
Brand value enhancement
Using clearly defined low-carbon materials strengthens the sustainability profile of electrical equipment and new energy products.
Supply chain collaboration
As a material solution provider, Jintong actively promotes carbon transparency upstream and empowers customers downstream, contributing to a cooperative, low-carbon industrial ecosystem.
Taking the implementation of GB/T 45441-2025 as a new starting point, Jintong is embedding carbon footprint management deeply into its corporate strategy. We will continue investing in low-carbon formulations, circular material concepts, and clean manufacturing technologies—driving BMC materials toward higher performance with lower carbon intensity.
We sincerely invite industry partners to work with us in advancing sustainable composite materials, contributing practical, engineering-based solutions toward global carbon neutrality.
