The LED bulbs that are available from stores have a life of approximately 5 years on 8 hours of daily use and the companies give 1 or 2 years replacement guarantee. Now comes the problem. The incandescent bulbs have zero percent plastic, but LEDs are almost completely made of plastic. When they expire they are also contributing to the landfill and will create big problems.

So, when touting LEDs as a big saver, the companies should also have the responsibility to take back the expired ones and recycle properly instead of going to land fill.
