en.Wedoany.com Reported - Taking Dongcheng Subdistrict as a pilot, Dongguan, China, has constructed a "zero-waste supply chain" for the power battery industry. Led by the chain master enterprise, Guangdong Poweramp Technology Ltd., and involving about 100 upstream and downstream companies, a four-dimensional system of "chain master coordination, full-chain collaboration, digital intelligence empowerment, and recycled material substitution" has been established. This promotes the transformation of solid waste treatment towards a full lifecycle closed loop.
Driven by the chain master enterprise, the Dongguan power battery industry has adopted an "environmental and recycling-oriented" design philosophy at the source. At the PACK stage, raw material costs have been reduced by an average of 1% annually. Production processes have been optimized, reducing scrap rate in electrode sheet processing from 5% to 1.2%, and NMP waste condensation recovery efficiency has exceeded 99%. In 2024, 1,900 tons were recovered and reused, saving costs of 18 million yuan. In the logistics stage, reusable turnover containers have been promoted, reducing the response time for collecting used batteries from 560 hours to 72 hours. At the end-of-life stage, partnerships with whitelisted recycling companies have established a closed loop. In 2024, the compliance rate for transferring used batteries and waste materials, as well as the solid waste resource utilization rate, both reached 100%.
In terms of digital intelligence empowerment, Poweramp has built a full lifecycle traceability management platform for batteries. The accuracy rate for predicting end-of-life batteries reached 98%, reducing transportation costs by 1.2 million yuan and increasing inventory turnover by 20% in 2024. Supporting enterprise Liteng Hui is projected to save nearly 4 million yuan in 2025 just from recycling tin slag and plastic waste.
Recycled material substitution has become a key driver. The Dongguan power battery supply chain strictly selects compliant recycled materials, with energy consumption for producing recycled materials being about 50% lower than that for virgin plastics. In 2024, internal resource utilization revenue reached 12.1 million yuan, creating a win-win situation for both environmental and economic benefits.
Currently, the construction of Dongguan's "zero-waste supply chain" for power batteries has achieved significant results. It has driven upstream companies, including Kaide New Energy and about 50 other major suppliers and 10 core strategic suppliers, as well as downstream clients like Ninebot Group, totaling around 100 companies, to jointly build a green closed loop. Taking Kaide New Energy as an example, the company invested 120 million yuan to advance automation upgrades, reducing its defect rate by 3%. Introducing centralized heating is expected to reduce carbon emissions by about 440 tons annually and save heating costs by millions of yuan.
Using the power battery industry as a breakthrough, Dongguan has carved out a distinctive path for green transformation in manufacturing. Dongguan will continue to deepen the construction of the "zero-waste supply chain," promote the practical experience of the "four-dimensional" system, and encourage more industrial clusters to integrate into the "zero-waste" development system.
