Material composition of consumer electronics

The dataset represents material composition of 25 commonly used consumer electronic products. The "Disassembly Data workbook" includes detailed, finely resolved data describing product composition of consumer electronics at the level of each major assembly and sub-assembly. Each sheet in this workbook represents a single product category, where most categories contain multiple product samples.The primary disassembly data are always represented as the total amount of each material per major component assembly and per product. The "Product Bill of materials" workbook includes total mass and mass percent of each material for all products studied and an average, maximum, and minimum mass and mass composition for each product category. It also contain literature values where available. The literature values were obtained, evaluated, and reorganized according to three parameters - transparency, level of detail and category consistency. If available, component-level detailed material compositions were included, but published data were more commonly available only in mass percentage composition of each material per product. Like primary disassembly, average maximum and minimum percentage material composition for published sources are provided if available. The qualitative analysis of each data point from published data sources is indicated next to each data point from published source.本数据集涵盖25款常用消费电子产品的材料组成情况。「拆解数据工作簿」包含精细详实的拆解数据，可细化至每一级主要组件与子组件层面，描述消费电子产品的材料组成。该工作簿中的每个工作表对应一类产品，多数产品类别下包含多份产品样本数据。核心拆解数据始终以每类主要组件、每件产品的各材料总用量形式呈现。「产品物料清单（Product Bill of Materials）」工作簿收录了本次研究中所有受试产品的各材料总质量与质量占比数据，同时提供了每类产品的平均、最大、最小质量及材料组成情况。若有可用文献数据，该工作簿也会一并收录。文献数据均按照透明度、细节层级与类别一致性三项参数进行筛选、评估与整理。若条件允许，会纳入组件级别的详细材料组成数据，但公开文献通常仅能提供每件产品各材料的质量占比数据。与核心拆解数据一致，若有可用的公开文献数据，也会提供其对应的材料占比平均值、最大值与最小值。针对公开数据源中的每一项数据点，其对应的定性分析结果会标注在该数据点旁。
