平板显示器回收的新挑战

Recycling of flat screens as a new challenge

显示屏(监视器和电视机)经历了从阴极射线管到平板显示器技术的快速变化。截至目前为止,只有少量的平板显示器已记录在废物收集点。平板显示器的数量越来越多,在未来需要足够的用于回收的基础设施。本文旨在通过液晶显示屏幕的回收对经济影响的案例研究来提供数量、成分、回收利用技术和经验的基本数据。对于组件和材料也适用于其他类型的电子产品,如黑色金属和有色金属,印刷电路板或电缆,回收途径和技术是众所周知的和可用的。目前,液晶显示器(LCD)在欧洲不回收。处置时,例如,通过焚烧,有价值的材料,其成分是不再可用。例如:铟具有重要战略意义的应用,如,太阳能光伏作为一种稀缺资源。液晶显示器在欧洲具有回收基础设施,因此是有用的。

Screens （monitors and TV sets） have undergone a rapid change in technology from cathode ray tubes to fiat panel displays. To date, only small quantities of fiat panel displays have been recorded at waste collection sites. Increasing quantities in the future make an adequate recycling infrastruaure necessary. This paper aims to provide basic data on quantities, composition, recycling technology and experience from a case study on economic impacts of liquid crystal display screens recycling. For components and materials which are also applied in other types of electronic products such as ferrous and non-ferrous metals, printed circuit boards or cables, recycling paths and technologies are well known and available. Currently, liquid crystal displays （ LCD ） are not recycled in Europe. When disposed of, for example by incineration, their content of valuable materials is no longer available. Here indium is of specific interest, as a scarce resource with strategic importance for applications such as photovoltaics. A recycling infrastructure for LCD in EuroDe could thus be useful.
