What kinds of plastic? All kinds! If you have a doubt, throw it in the green topped bin anyway!
Yup, the same with aluminum, if you are not sure whether it qualifies, throw it in green topped bin anyway!
Once again, any kind of paper will work, newspaper, colored paper, notebook paper... If you have a doubt throw it in the blue topped bin anyway!!!
And remember, if you have any doubt about whether something is recyclable or not... Throw it in their respective recycle bins anyway!!!
