CBPM’s Green Alternatives for Thread Production

China Banknote Printing and Minting (CBPM) has been implementing a series of clean production and carbon reduction measures in the production of raw materials such as paper, thread, and ink, and such as using toxicity auxiliary materials and reducing pollutants, in order to make the production of the renminbi and other currencies more environmentally friendly.

This article shares the efforts made by CBPM in developing environmentally friendly materials for the production of threads.

In the early days of its thread production, to ensure product performance and quality, CBPM’s technology involved the use of large amounts of highly volatile, toxic, and hazardous solvent-based coating materials which generated volatile organic compounds (VOCs) that can result in atmospheric pollution.

Although CBPM adopted advanced regenerative thermal oxidation (RTO) technology to collect and treat the VOCs, ensuring that pollutant emissions complied with national standards, it says that this approach was passive, uneconomic, unsustainable, and did not align with the fundamental principles of pollution source control and substitution in clean production.
