In this section we shall look at the different ways of handling computer peripheral components.
Disposing of Batteries
- Remove the used battery from the computer and place it in a resealable bag or other closed container. This prevents contamination if the battery leaks. Place only one battery in a bag or container. Be sure to carry out this safety measure as there can be enough juice left in a battery to cause a short circuit and ignite a spark if the battery comes into contact with the terminals of another battery. Cover battery terminals with adhesive or electrical tape as an additional precaution.
- Contact your local municipal authority or private trash collector to inquire about the policies for hazardous waste removal. Many municipalities have certain days when items considered to be hazardous are picked up or can be dropped off at an area recycling center. There may even be an ordinance in your town or city prohibiting disposing of rechargeable batteries in the regular trash. Residents can also go to official municipal website links where they can learn more. Some municipalities distribute print newsletters, which publish the recycling calendar along with listing the recycling services available.
- Check out local retail stores that sell computer equipment and batteries. A number of major retailers now provide recycle bins right in the stores. Collection points are found at many Staples. Other retailers who sell computer batteries will often take back an old battery for recycling when you buy a new battery.
NB: Never dispose of batteries in fire, as they could explode.
Disposing of CRTs
A CRT contains phosphors on the inside of the screen that can harm the environment if placed in a landfill. The large boxy shell of the CRT also takes up a lot of space in a landfill. Dispose of a monitor at your local hazardous-waste recycling center.
Disposing of Circuit Boards
Circuit boards contain lead in their soldering, so they should not be put in the regular trash. Take them to the local hazardous-waste disposal site, or contract with a company that handles them.
Disposing of Ink and Toner Cartridges
Ink and toner cartridges should be taken to recycling centers for proper disposal. It may also be possible to sell them to companies that refill and reuse them, but some people feel that this is not a good idea. Those re-manufactured cartridges sometimes do not work very well, and can damage the printers they are installed in, and by selling such companies your “empties” you are encouraging that industry.
Disposing of Cleaning Chemicals
The most common cleaning chemicals used for computers are alcohol and water, neither of which are particularly hazardous to the environment. However, if you use other chemical products, consult an MSDS for the product or consult the manufacturer to find out whether any special disposal is required.

NB A number of non-profit organisations collect electronic equipment including computers and printers, either for reuse or for de-manufacture and recycling. Recipients pay nothing for the equipment or buy it at a heavily discounted rate. Developing countries benefit most from these schemes, but recipients also include community groups. |
