The plastic cages are recyclable. They are a #5 on the recycling scale
The most frequently recycled plastics are #1 and #2 bottles. Other
plastic items marked #3 through #7 - like butter tubs, single-use cups,
video tapes/cassettes - can occasionally be recycled. These types of
plastics are sometimes included in curbside collection. If your service
provider does not currently accept these materials, some recycling
centers in Minnesota do accept them via drop-off if you separate them by
code. For instance, the City of Coon Rapids recycling facility accepts
#1, #2, #4, #5 and #6 plastics.
Check with your local service provider to see what types of
plastics they accept, and keep an eye out for special plastics
collection events, such as garden plastic collections (seedling trays,
pots, hanging baskets, etc.) at garden centers/nurseries each summer.
