进口废塑料清洁程度定量化合格评定方法的探讨

目前国内对进口废塑料清洁程度的合格评定,长期以来一直采取感官检验的定性方法,引起了较多争议.以<进口可用作原料的固体废物环境保护控制标准--废塑料>(GB16487.12)为依据,分析了GB16487.12对进口废塑料清洁程度进行规定的原因,并在此基础上探讨了对进口废塑料清洁程度采取定量化的合格评定原理,提出参照<一般工业固体废物贮存、处置场污染控制标准>(GB18599)和<生活垃圾填埋污染控制标准>(GB16889)对进口废塑料清洁程度制定定量化限量要求,并建议尽快修订现行国家标准<进口可用作原料的固体废物环境保护控制标准--废塑料>.     

浅谈国际原油价格暴跌对进口废塑料行业的影响及建议

作为资源的重要补充,近年来国内塑料加工行业对进口废塑料的需求市场不断扩大,但作为原油的下游产品,因原油价格波动带来的经营影响和环保风险不容忽视。为有效规避风险,提升行业竞争力,在源头控制、行业转型、通关便利等方面提供可行性建议。     

江苏镇江口岸进口废钢创历史新高

从镇江检验检疫局传来信息,2009年1—8月份,镇江港共进口废钢43.543万t,比镇江口岸历史上全年进口废钢量最高的2003年增长了21%。镇江检验检疫局业内人员分析,镇江口岸进口废钢一路攀升,主要有以下原因：一是受金融危机影响,进口废钢成本优势凸现。

进口废旧塑料的现场鉴别

废塑料是废物原料的重要组成部分,近年来得到各界广泛的关注和重视。我国废塑料的进口量呈稳步增长的态势,出入境检验检疫部门作为进口废塑料的施检机构,必须了解废旧塑料知识,掌握废旧塑料鉴别的方法技巧,这是响应国家质检总局"科技兴检"战略、不断加强技术执法的必然要求。     

Trends in waste plastics and recycling

Zero emission is an ambitious project aimed at the conversion of the conventional top-down or one-directional flow type production systems of modern society to those of a recycling type. The basic idea underlying this project is to understand in detail the material flow mechanism in a particular segment of society and to evaluate the transformability of the hitherto one-directional types of process into recycling types. The authors, members of the Zero-Emission Research Group of Japan, are investigating the material flow of plastics in Japan. The present work describes the features of this project, as well as the results obtained so far. Received: May 28, 1998 / Accepted: October 16, 1998     

废旧塑料的简易分类方法

塑料制品因其具有质量轻、外观美、加工方便、经济实用等特点而颇受人们青睐,广泛用于各行各业和日常生活用品中,但塑料制品的大量使用也给环境造成了严重污染,消除塑料污染的最积极的办法是对废旧塑料进行回收再利用.塑料种类繁多,不同类别的塑料性质和用途都不相同.介绍几种塑料分类的简易方法,以利于废旧塑料的回收利用.     

Studies on the dechlorination and oil-production technology of waste plastics

 Recycle technology for waste plastics containing polyvinyl chloride (PVC) has been developed in the Hokkaido National Industrial Research Institute for the production of solid and liquid fuel, and has established a recycling process which includes a dechlorination process for PVC plastics, and a two-stage catalytic pyrolysis process for plastics using zeolite catalysts. The dechlorination equipment consists of a two-axis screw extruder with a heating element, which can remove chlorine up to 99.9 wt. % from PVC containing plastics as hydrogen chloride. The product had about 44 000 kJ/kg calorific value and was fed into the next oil production process, although it could also be used as a solid fuel. Natural and synthetic zeolite were used as catalysts for the two-stage catalytic process, which produced a light oil with a boiling point which was between those of kerosene and gasoline. The yield of this oil reached 82 wt. %. The chemical type was analyzed using liquid chromatography, and was found to have many aromatic compounds. These technologies make it possible to produce a nonpolluting, high-calorie solid fuel and a liquid fuel very efficiently. Received: July 19, 2000 / Accepted: September 21, 2000

Toward maximizing the recycling rate in a Sapporo waste plastics liquefaction plant

Sapporo Plastics Recycling Co., Ltd., (SPR) started its commercial operation of waste plastics liquefaction in 2000. At first only hydrocarbon oil was reclaimed, this being derived from the waste plastics liquefaction process under the Japanese Containers and Packaging Recycling Law. Presently, thermal degradation residue and hydrochloric acid are being produced as by-products in addition to the hydrocarbon oil. As a result, the SPR plastics liquefaction plant has achieved a high reclamation rate of 96%, and 93% of the recycled products have been reused in Hokkaido, where SPR is located. The technical problems caused by corrosion and clogging have been solved. Chemical Feedstock Recycling & Other Innovative Recycling Techniques 6
