Plastic #5 - Polypropylene: one of the least recyclable plastics
Considered one of the safest plastics, #5 plastic is used for packaging items such as yogurt, cottage cheese, margarine and vitamins, and is contained in food wraps and bottle tops. It is one of the least expensive plastics to make. However, the process of recycling plastic #5 is less efficient than other plastics, and the end result has little market value.
