干磨纸浆进口存在多重隐患，专家建议完善标准、抬高门槛

Core Viewpoint - The import of "dry ground pulp" under the guise of recycled paper pulp is essentially a method of importing foreign solid waste, posing significant environmental and health risks to the domestic paper industry [2][5][6]. Group 1: Industry Background - Since January 1, 2021, China has completely banned the import of solid waste, disrupting the supply of imported waste paper for paper manufacturers [2]. - The production of legitimate waste paper pulp requires extensive processing, achieving a fiber content of over 91.5% with minimal impurities, while dry ground pulp skips most of these essential steps [2][3]. Group 2: Environmental and Health Risks - Contaminants such as plastic fragments, heavy metals, and microorganisms can enter the domestic production chain through dry ground pulp, leading to potential health hazards in products like food packaging and sanitary paper [3][5]. - The presence of these pollutants can cause secondary pollution in water treatment systems and may clog machinery in paper production, affecting product quality [3][6]. Group 3: Regulatory and Standardization Issues - The newly released national standard for recycled paper pulp lacks mandatory requirements for key quality indicators, unlike stricter foreign standards [5][10]. - Experts have called for the revision of national standards to include compulsory indicators for fiber integrity and impurity levels, as well as enhanced detection standards for contaminants [10][11]. Group 4: Recommendations for Improvement - Experts recommend strengthening customs supervision and implementing comprehensive inspection and testing to prevent contaminated materials from entering the domestic market [10][11]. - Suggestions include introducing advanced detection technologies and establishing a fiber traceability system to ensure the integrity of imported materials [10][11].
