Plastic #5 (Polypropylene) Alternative ways to recycle Recycle Curbside Plastic #5 bottles and containers are the only plastic #5 that can be placed in your recycle cart. These can sometimes include yogurt cups and containers. Clean Out Containers If a container once held food, clean and dry the container as well as you can before recycling it. Containers with food, liquids and other residues can contaminate whole batches of recycling and are often sent to a landfill. Keep Caps On When recycling plastic water bottles or plastic containers with colorful caps, leave the cap on. While caps used to be difficult to separate from bottles, recycling locations have advanced, and it is much easier now to recycle the whole bottle at once. Find out more. Avoid Heating Plastic Keep plastics containing food or drink out of the microwave, dishwasher and other hot places, like your car. The warmer plastic gets, the more it tends to break down, melt, and release chemicals.
