Abstract

The objectives of the present study are to estimate future quantities of electronic waste (e-waste), and to the estimate the total cost for e-waste recycling in California. To generate estimates, we used a time-series materials flow analysis model (MFAM). The model estimates future e-waste quantities by modeling the stages of production, usage, and disposal. We consider four scenarios for the estimation of future e-waste generation. To calculate cost for recycling, we used technical cost modeling (TCM). The results of the present research indicate that the outflow (recycling) amount of central processing units (CPUs) will increase and will reach approximately 8.5 million units per year in 2013, but the outflow (recycling) of cathode ray tube (CRT) monitors will decrease from 2004 in California. After the State of California enacted the ban on landfill disposal of e-waste, recycling became the most common end-of-life (EOL) option in California. Also, after 2005, the State of California will need more than 60 average-sized materials recovery facilities (MRFs) to recycle the number of personal computer systems generated

加州报废个人电脑系统:未来回收所需的排放和基础设施分析

本研究的目的是估计未来电子废物(电子废物)的数量，并估计加州电子废物回收的总成本。为了产生估计，我们使用了时间序列物料流分析模型(MFAM)。该模型通过模拟生产、使用和处置阶段来估计未来电子废物的数量。我们考虑了四种情景来估计未来的电子废物产生。为了计算回收成本，我们使用了技术成本模型(TCM)。本研究结果表明，2013年，加州中央处理器(cpu)的流出(回收)量将增加，每年将达到850万台左右，而阴极射线管(CRT)显示器的流出(回收)量将从2004年开始减少。在加利福尼亚州颁布了禁止填埋电子垃圾的禁令后，回收利用成为加州最常见的报废(EOL)选择。此外，2005年以后，加利福尼亚州将需要60多个中等大小的材料回收设施(mrf)来回收产生的个人电脑系统的数量
