The benefits of e-waste recycling in The Netherlands was studied for the year 2009 using Life Cycle Assessment (LCA). Avoided greenhouse gas emissions from material recovery of all collected e-waste and the destruction of (H)CFC containing coolants from cooling and freezing appliances were calculated using the IPCC 2007 method. In 2009, about 73,000 tonnes of CO2 equivalents were avoided due to material...
The present paper reports on selected findings made within the Swedish joint R&D project “Sustainable Recycling of Flat Panel Displays”. The results presented are specifically related to i) Process for indium recovery from LCD glass; ii) Recovery and re-use of optical components; and iii) Sustainability rating of different recycling scenarios involving mainly large-scale shredding and manual dismantling...
A review of the materials used in liquid crystal display (LCD) monitors is followed by the development of a parametric model for the quantification of material masses from waste monitors. The model uses diagonal length as an input which is first translated into a range of screen areas using viewing area aspect ratios. Next, the model divides LCD monitor components into those that are scaled by the...
In recent years, electronic waste has emerged as a waste stream of concern for many reasons; including the need to handle hazardous or extract valuable materials. Within this e- waste stream, cathode-ray tube (CRT) glass waste, from televisions (TVs) and computer monitors, is of particular concern because of high recycling costs and low secondary material value. Economic issues are thus a significant...
As LCD monitors increasingly enter the e-waste stream, there is a need to better understand what recyclers might expect in terms of what they will receive and what materials they will need to manage. Here, we identify materials used in the production of key subassemblies, and note uncertainties in the composition of the LCD assembly, film set (comprised of the reflection foil, light guide, prism foil,...
