再生纸浆“带病”进口为何屡禁不止

Core Viewpoint - The import of recycled paper pulp in China faces significant challenges due to the use of dry pulping technology, which has led to the entry of contaminated solid waste disguised as recycled pulp, prompting calls for stricter regulations and standards in the industry [1][5][6]. Group 1: Regulatory Issues - In September 2023, Qingdao Customs seized 746.78 tons of goods declared as "recycled paper pulp," which were found to be solid waste prohibited for import [1]. - The implementation of the "ban on waste" policy in January 2021 aimed to transition from importing waste paper to importing pulp, but some companies still import waste paper under the guise of recycled pulp [1][5]. - The General Administration of Customs has mandated that importers specify the production method of recycled pulp, either "dry" or "wet," to enhance regulatory oversight [5][6]. Group 2: Dry Pulping Technology Concerns - Dry pulping technology, which involves mechanically crushing waste paper without proper purification processes, results in high contamination levels, with up to 20% impurities [4][5]. - Experts argue that dry pulping is not a mature technology and poses safety risks due to the generation of flammable dust during production and storage [5][6]. - The production cost of dry pulping is lower than wet pulping by over 15%, incentivizing companies to take risks despite potential customs rejections [4][5]. Group 3: Industry Standards and Recommendations - The current national standard for recycled paper pulp is deemed insufficient, lacking mandatory controls on microbial content and heavy metals, which allows contaminated materials to enter the country [6][7]. - Experts recommend revising the national standard to include stricter quality indicators, such as limiting impurities to no more than 0.5% and setting maximum allowable levels for heavy metals [8][9]. - There is a consensus among industry experts that dry pulping should not be included in the definition of recycled paper pulp to prevent the import of solid waste [9]. Group 4: Technological Innovations and Future Directions - The Chinese paper industry is shifting towards more sustainable practices, including the adoption of chemical-mechanical pulping, which has a higher raw material utilization rate of up to 90% [10][11]. - Projects like "forest-pulp-paper integration" are being developed to enhance domestic raw material supply, reducing reliance on imported recycled pulp [11][12]. - The industry is encouraged to invest in green technologies and improve supply chain management to enhance competitiveness in a low-carbon economy [12].
