Ziploc bags are recyclable
The plastic used in Ziploc bags is known as "film" in the recycling industry. It is a thin, clear plastic made of either low-density polyethylene (LDPE, recycling #4) or high-density polyethylene (HDPE, recycling #2). Most film is recycled into composite lumber, a highly durable building material used for decks, benches, and playground equipment.
It is important to carefully follow your community's guidelines for recycling film. Some municipalities may accept Ziploc bags in their recycling programs, while others may not. To find your closest plastic bag recycler, you can use the search tool on PlasticFilmRecycling.org.

They are made from LDPE or HDPE plastic
Ziploc bags are made from LDPE (low-density polyethylene) or HDPE (high-density polyethylene) plastic, also known as "film" in the recycling industry. This plastic is thin, flexible, and lightweight, making it easily airborne and susceptible to becoming litter if not properly secured in recycling bins. LDPE and HDPE plastics are identified by the recycling numbers #4 and #2, respectively.
Due to their composition, Ziploc bags can be recycled and are increasingly accepted at recycling facilities. However, it is important to note that they are recycled differently from plastic bottles and containers. Most recycling facilities are equipped to handle bottles and containers, but plastic bags and films may require special handling. Therefore, it is crucial to check with local recycling entities, as guidelines may vary from one location to another.
To recycle Ziploc bags, they should be clean and dry. Some municipalities may have specific requirements, such as removing the zip tabs before recycling. It is recommended to carefully follow the guidelines provided by your local waste management system.
The recycled LDPE and HDPE plastics from Ziploc bags can be transformed into composite lumber, a durable building material used for decks, benches, and playground equipment. Additionally, companies like Trex utilize recycled plastic bags to create new packaging, and emerging technologies are being developed to break down plastic into its building blocks for reuse as brand-new plastic.
