两项研究，TRIFLE（用于分析DEEE和优化TRI des PLASTiques DEEE技术（分析Wastewater和优化Wastewater塑料的分选技术））。和VALEEE（用于从废物中回收成分、材料和物质），在法国政府的支持下，大里昂地区（大里昂）、罗纳-阿尔佩斯地区和法国生态组织“生态系统”，并涉及实验室、回收材料用户和回收商合作伙伴，进行了关于法国垃圾的表征、分类和回收的研究。为了确定10吨批次的不均匀性，在研磨之前将废纸浆分类成系列。样品被拆除，塑料颗粒进行了分析，以估计其组成。然后将这批塑料粉碎并提取金属，在工厂出口处对含有塑料的残留物进行取样和分析。塑料样品的详细表征用于计算估计的采样误差和总体测量误差。确定了样品的大小，以达到令人满意的准确度为最具代表性的聚合物可能被回收后的回收。提出了一种简单的表征方法，用于回收厂使用，以确定这种废物的塑料组成。该程序进行了验证，第二批10吨的sWEBs收集从另一个位置，并通过不同的回收facility.This文章介绍了采样协议的设计方法，然后表征协议及其使用限制。(C)2014爱思唯尔有限公司版权所有。
Two studies, TRIFLE (For Analyse des gisements DEEE et optimisation des technologies de TRI des PLastiques DEEE (analysis of WEEE and optimization of sorting technologies for WEEE plastics).) and VALEEE (For VALorisation des composants, matieres et substances issus du gisement DEEE (Recovery of components, materials and substances from WEEE).), supported by the French State, the Greater Lyon area (Grand-Lyon), the Rhone-Alpes Region and the French eco-organization "Eco-systemes", and involving laboratories, recycled material users and recycler partners, were conducted concerning the characterization, sorting and recovery of French WEEE (Waste Electrical and Electronic Equipment).To determine the heterogeneity of a 10-ton batch, the WEEE was sorted into families before grinding. Specimens were dismantled and plastic particles were analyzed to estimate their composition. The batch was then crushed and the metals extracted.The residue containing plastics was sampled at the outlet of the plant and analyzed. The detailed characterization of the plastics sample was used to calculate the estimated sampling error and the overall measurement error. The sample size was determined so as to achieve satisfactory accuracy for the most represented polymers likely to be recovered after recycling.A simple characterization methodology for use by recycling plants was proposed in order to determine the plastic composition of this waste. The procedure was validated on a second 10-ton batch of sWEEE collected from another location and treated by a different recycling facility.This article presents the sampling protocol design methodology, then the characterization protocol and its usage limitations.
