    Hi friends,
    An ISO Audit is proposed to take place in our college campus.We need to take measures concerned with the environment.

    My question is:

    How do you dispose components such as burnt out ICs , Diodes ,Capacitors and lifeless batteries?

    I have googled out to find results such as donating old phones and CRTs to NGOs and companies such as vadafone..

    Is there any other way out?some novel ideas for a smaller scale?

    For your replies,Thanks in advance ..

    These can generally go in the trash.

    Conventional batteries can also go in the trash, but specialty batteries such as NiCad or NMH need to go to the special disposal, most cities have something for this kind of trash (same as with lead acid batteries). The chemicals in them can be recycled, and are highly toxic. Bad for the drinking water.

    Chips, transistors, and LEDs can have highly toxic materials too (especially LEDs), but they are considered encapsulated and are no threat to ground water.

    They are not considered so toxic you can't store them, so it is OK to build a stock pile. I think quantity makes it more economical to deal with.

    Waste in the USA is generally buried. Burning of waste indiscriminately creates air pollution. Plastics and other synthetic materials become toxic when burnt. You are going to have to figure this one out yourself, since we are dealing with different standards.

    Just set aside a few small bins and mark them. Batteries should be separated by type and labeled "To xyz recycling" whereas ICs, transistors etc often have a small amount of gold in them so mark that box as semiconductors for possible gold extraction.

    Not everything (especially not what's been around or donated to colleges) is lead free so I'd have one more box labeled "potential lead content, take to abc recycling"

    Some retail stores will also take dead batteries for recycling.
