Blog 4: “Dealing with electronic waste: modeling the costs and environmental benefits of computer monitor disposal” by Molly Macauley et al.

The previous blog was about an article that assessed the social aspect of e-waste. However, the social view on an issue can be very different from a manufacturer’s point of view. Thus, “Dealing with electronic waste: modeling the costs and environmental benefits of computer monitor disposal” by Molly Macauley et al. would help to develop a solution from a developer’s perception. The article takes a large component of electronic waste, computer monitors, and models the cost and benefits of reducing the waste caused by CRT monitors. Macauley certainly takes into account the environmental effects of E-waste like Robinson. For example, the statement “A primary concern in managing this large quantity of obsolete electronics is that the hazardous materials they contain can be released into the environment during disposal with potential adverse effects on human health”. However, ultimately the main concern of Macauley was the cost effectiveness of the disposal of these monitors. In the results, it is shown that the cost of handling the waste would be about $1 per monitor. This doesn’t seem to be very much but in the experiment with a controlled amount of monitors it added up to about $13.5 million compared to a human health cost of only $2.7 million. Thus according to a manufacturing point of view, recycling the E-waste would be less cost effective than just allowing them to be dumped where they can cause harm.

How shocking are those numbers? I mean, if i were the manufacturer i wouldn't want to bother dealing with the recycling of my products either. However, ethically it would be the correct thing to do, right? I mean is it really their responsibility, or is it the responsibility of those who purchased the product?

Blog 3: “E-waste: An assessment of global production and environmental impacts”, B.H. Robinson

In “E-waste: An assessment of global production and environmental impacts”, B.H. Robinson attempts to “assess the global production of E-waste, the contaminants and contaminant fluxes associated with E-waste, and the likely environmental impact of E-waste associated contaminants”. In other words, Robinson takes a social stand point and attempts to explain the impacts of E-waste caused by society and what the consequences against society will be. Robinson starts his review by displaying the world’s production of E-waste. He calculates that by 2015 E-waste will reach a volume of 9.8 million tons. That is only 8% of total municipal waste, but that 9.8 million tons is important because it is nearly double the projected 5.5 million tons for 2010. The review continues on and explains the effect of E-waste on many aspects of the environment, using a case study on Guiyu, a city in China, and other E-waste recycling centers. The results of the case study showed negative effects from E-waste on the aquatic systems, air, soils, and humans themselves. E-waste contaminants enter the water near dumpsites, escape into the air as dust, and into soil by leaking through the ground under dump sites. These contaminants contain many different chemicals that can affect the ecosystems as well as the inhabitants of the regions around dumpsites and recycling plants.

This article was absolutely shocking! Its obvious that the author was looking for society to react to this negatively. I can tell that he used this study to show to people that e-waste is a major issues not only in the U.S. but all over the world. My question is though, why doesn't he explain how we can fix this huge problem.
