Some electronic items require special e-waste recycling because they contain hazardous materials that can harm the environment and human health if disposed of improperly12. Laptop batteries and CRT monitors are examples of such items.

Laptop batteries are usually made of lithium-ion or nickel-metal hydride, which are both toxic and flammable substances34. If laptop batteries are thrown in the trash, they can leak, catch fire, or explode, causing pollution and injuries5 . Therefore, laptop batteries should be recycled at authorized collection centers or through manufacturer take-back programs .

CRT monitors are old types of display devices that use cathode ray tubes, which are glass tubes that emit electrons to create images on the screen . CRT monitors contain lead, mercury, cadmium, and phosphor, which are all harmful metals that can contaminate the soil, water, and air if dumped in landfills . Therefore, CRT monitors should be recycled at certified e-waste facilities or through retailer or manufacturer trade-in programs .
