The lids to plastic bottles are made of different grades of plastic than the bottle itself. Mixing lids in with plastic bottles will diminish the value of bottle-grade plastic collected in that fashion. Bottle caps can be recycled separately through the Aveda Recycle Caps program.
Aveda Recycle Caps Program
AVEDA Recycle Caps Program accepts bottle caps that are rigid polypropylene plastic, sometimes noted with a 5 in the chasing arrows recycling symbol. This includes caps that twist on with a threaded neck such as caps on shampoo, water, soda, milk and other beverage bottles, flip top caps on tubes and food product bottles (such as ketchup and mayonnaise), laundry detergents and some jar lids such as peanut butter.
