If anyone is interested in the aspects of reuse and recycle touched on in this article, I highly recommend Junkyard Plant, a book about recycling largely but not exclusively focused on China. There are a couple of chapters on electronics and Shenzhen, as well as other chapters ranging from paper & cotton, steel, plastics, aluminium, etc, and the entire sourcing chain.
