Plastic Cap Recycling Contest for Schools

Schools within Huntsville, Alabama’s city limits are eligible to participate in Green Team’s nationally award-winning plastic cap recycling program. Registration begins September each year and the contest is held annually from October – March.

What happens to all those caps collected by your school? Green Team sends them on trucks to Troy, Ala. to KW Plastics, the largest plastic recycler in the world! The caps are recycled into new plastic paint containers that you can see on the shelves of Home Depot, Lowes and Walmart stores.

Schools collected more than 20,000 pounds of plastic caps during the contest in 2021!


The contest begins October 2022 and ends March 2023. To participate in the contest, you must register for the program here. Before officially participating in the contest, Green Team must have the participant’s W9 and New Vendor Application form on file.

Please contact Green Team at green.team@huntsvilleal.gov for more information.

  • Caps must be plastic and the twist on/off type. These are found on plastic bottles of juice, milk, ketchup, laundry detergent, water, soda, peanut butter, shampoo, toothpaste, etc. The caps can be any shape, color or size. Caps cannot have metal of any kind in them. No spray caps such as glass cleaner bottle sprayers are allowed.
  • Caps should be cleaned and bagged in one large heavy-duty bag. Please take caps out of smaller bags and empty into one large bag instead. The caps will be weighed by Green Team, and awards will be based on the total weight of accepted twist on/off caps. Bags turned in with excessive non-twist off caps, such as coffee lids, margarine lids and yogurt lids, will not be counted toward awards.

Consider collecting the caps in your lunchroom as well as asking the students to bring them from home. Green Team will collect caps from schools at least once every other month. All participating schools will be notified at least one week in advance of pickup dates.

Participating organizations understand they are responsible for sending bags labeled with school name for monthly pickup.

Thank you for joining the effort to recycle and take care of your community!
