Topic: Recycling electronic waste

anonymous
I am an active member of environmental committee at my work place. We had an issue in last meeting; we want to control end-of-life or damaged electronics going in to the regular waste. Is there anyway we can scan the waste and segregate electronic waste?

    The best way to recycle computer boards is through a commercial vendor and not to put them in the trash. There are several dollars of recoverable heavy and precious metals in the boards, but the trouble is that it's often more costly to separate the metals than it is to throw out the entire board. There is an entire industry dedicated to recycling and disposal of electronic equipment. In Europe they refer to it as e-wastes.

    On the Internet, one can find a number of firms that dispose of computer parts and guarantee that they will be wiped of all data, and/or reused where possible, and disposed of safely.

    A motherboard often contains what is termed "digger gold" — small amounts of precious metals which can be recovered by soaking the boards and electrical components first in nitric acid (it dissolves the silver) and then in aqua regia, which gets the gold. The process may be marginally cost effective because of the cost of disposal of the acids, but the article I saw was written when Gold was $100 per troy oz. Today, the prices for precious metals may make the processes more attractive and financially viable.

    Search the web for "e-wastes" and for computer recycling. I'm sure you will find what you need. As far as separating the wastes, that has to be done at the office by putting bins up for electronic parts and training personnel to segregate. It's not economical to try and do it after the waste gets mixed with the trash.

    Recycling may help you earn profits and you are also helping the environment from a good way of waste management. There are company that handle waste sorting and in fact they convert industrial waste to renewable energy, which mostly the biogas and methane gases came from.
