"干法"与"湿法"有何区别？进口再生纸浆时填写"干法"或"湿法"，对于进口再生纸浆企业意味着什么？ 该举措能否有效遏制纸浆"洋垃圾"进入中国境内？新规将对中国造纸行业将产生什么影响？当初制定 《再生纸浆》国家标准时，为何要给干磨纸浆留个后路？ 北京林业大学材料科学与技术学院教授许凤介绍，正规的废纸浆生产需要在液态下进行除渣、筛选等 净化工序，再经过浓缩加蒸汽处理（如热分散），高温干燥最终形成废纸浆。经过这些工序生产的再 2025.10. 10 本文字数：2293，阅读时长大约4分钟 作者 | 第一财经 章轲 封图 | 经过正规工序生产进口、符合卫生标准要求的再生浆板。摄影/章轲 10月9日晚，海关总署发布关于进口再生纸浆申报要求的公告，规定进口货物收货人或者其代理人在 申报进口再生纸浆（商品编号47062000）时，应在报关单备注栏注明生产再生纸浆使用的工艺方 法，根据实际情况填写为"干法"或"湿法"。 自2021年1月1日起，我国全面禁止以任何方式进口固体废物，禁止我国境外固体废物进境倾倒、堆 放、处置。海关总署表示，此举旨在规范进口再生纸浆申报管理，强化进口监管。 对于当初《再生纸浆》国家标准给干磨纸浆" ...

Group 1 - The Chinese government implemented a ban on foreign waste imports in 2018 to prevent pollution transfer and protect public health, which has received widespread approval [1] - The ban has led to positive effects on improving China's environmental quality, but some entities have exploited loopholes by sending processed waste paper from developed countries to Southeast Asia before exporting it to China, which poses health risks and creates unfair competition for compliant paper companies [2] - The production of legitimate waste paper pulp requires extensive purification processes, while dry ground pulp production skips most of these steps, resulting in lower quality and potential contamination [2][3] Group 2 - There are existing national recommended standards for recycled paper pulp in China, but reports of impurities and pathogens in imported dry ground pulp have emerged, prompting calls for stricter enforcement and the conversion of recommended standards to mandatory ones [3] - Domestic companies utilizing recycled fibers have a rigid demand for quality, employing various methods to remove contaminants to ensure their products meet market standards, thereby minimizing safety risks in final products [3]

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].
