Different kinds of plastic cannot be blended together during the recycling process. If you wish to get rid of plastic toys, try donating them to a charity or a church group for children. If the toy is broken, please put it in the garbage and not in with recyclable items. We have to assume that items used for food are not clean. Also, food residues can dry and give an item the appearance of being clean when it is not.
Food waste is a contaminant for recycled paper.
Frozen food boxes have a wax coating which cannot be removed during the recycling process. Milk and juice cartons have a plastic coating which can be removed during recycling and the high quality paper underneath can then be retrieved. Most packaging for dry goods does not have either a wax or plastic coating and should be placed in the mixed paper bin. Window glass and drinking glasses are transparent. Glass is formed at different temperatures, depending on its chemistry.
