What can and can't be recycled beginning with L

Light bulbs 

There are three main kinds household light bulb; old-style filament bulbs, energy-saving bulbs (CFLs), and LEDs. None of these can be recycled alongside glass, but can be brought to a recycling centre. Some energy-saving light bulbs contain small amounts of mercury, so these should be recycled wherever possible. LED bulbs last longest, have the smallest environmental impact, and don't contain dangerous chemicals.
