The study by Pradesh/Manhart, the study by Williams/Kahhat, WR3A's data, the study by the UN (showing most informal sector e-scrap is "domestically generated", not imported, in developing countries), and some upcoming research from MIT, is all closing in on one basic fact.
It is a Myth that 80% of USA used electronics exports are junk.
Since we have repeatedly asked for the source of the oft-printed 80% statistic, and have found only circular references (BAN citing a journalist in Ghana, the journalist citing BAN), we think this stat needs a fork stuck in it, it's done.
What I predict is that BAN and ETBC will begin to insert the words "up to" in front of the 80% statistic. I'm sure there's been a load that was 80% junk, so that would be a correct statement. Let's just remember, you saw it here first.
I'll try to follow up and post some links to the studies above, but am on my way to NYC in a truck... starting NOW.
