You have a few different options for preventing your computer monitor from reaching a landfill.
Donate the monitor. Before attempting to recycle a computer monitor, consider donating it to a charitable organization. Obviously, if the monitor is extremely old or doesn't work, you can't donate it and recycling is your only option.
Local government options. To find a recycling agency in your area, you can contact your local city, county, or state government for more information. If your state has a department of "environmental quality," or "environmental conservation," or "environmental protection," it probably can help you determine the best method for recycling your monitor. Some states place limits on how many monitors a company can recycle in a month. Some cities offer electronics recycling, including computer monitor recycling, at a certain time each month. Check with local officials for information in your area.
Recycling companies. Companies that specialize in recycling sometimes accept computer monitors for recycling. You'll have to look in your local telephone book for these options.
New computer. If you purchase a new computer from particular manufacturers, they might allow you to recycle the equipment you're replacing for free. Some retail stores will recycle old computer equipment for a small fee after you purchase a new computer from them, too.
