Make Your Own Cellphone From Scratch. The DIY Cellphone is a working (albeit basic) cellphone that you can make yourself. It can make and receive phone calls and text messages store names and phone numbers display the time and serve as an alarm clock. It connects to GSM networks (lik
· In the present study a model of closed-loop recycling of copper from PCBs is demonstrated which involves the sequential application of bioleaching and electrowinning to selectively extract copper. This approach is proposed as part of the solution to resolve the challenging ever-increasing accumulation of electronic waste e-waste in the environment.
· E-waste is growing at a rapid and uncontrollable rate and is the fastest growing portion of the municipal solid waste stream. Currently WEEE constitutes 1 of municipal waste in the US (Li et al. 2006) and 4 in the EU (Yla-Mella et al. 2004).As these PCs become obsolete they are replaced and the old PCs are disposed.
