Plastic bags are labelled with a number inside a triangle, with each number corresponding to a different type of plastic. Number 4 plastic bags, also known as low-density polyethylene (LDPE), are commonly used in shopping bags, dry cleaning bags, and cling wrap. While number 4 plastic bags can technically be recycled, they are not accepted by most curbside recycling programs due to the risk of jamming machinery. Instead, it is recommended to return them to collection bins at participating retail stores or local recycling facilities. Before recycling, it is important to ensure that the bags are clean and dry, free from food particles, and stuffed into one larger bag to facilitate easy handling and processing. Recycled number 4 plastic can be repurposed into new bags, composite lumber, shipping envelopes, and other products, helping to reduce plastic pollution and minimise environmental damage.

What You'll Learn
Plastic bags cannot be recycled in curbside recycling bins
Plastic bags are a major source of pollution, and while they can be recycled, they cannot be placed in curbside recycling bins. This is because plastic bags tend to get stuck in recycling equipment, causing downtime and requiring extra labour to rectify. Most recycling facilities are designed to handle plastic bottles and containers, not bags.
However, plastic bags can be recycled at many large retail stores, which often have bins located near the front entrance. These retailers collect plastic film packaging from consumers and back-haul it to multiple businesses that recycle it into new products. Some of the largest recyclers of plastic bags in the USA include Trex and Kroger, Safeway, Target, and Walmart.
Before recycling plastic bags, it is important to ensure they are clean and dry, free of any food residue, stickers, labels, staples, and receipts, as contamination can affect the entire batch. It is also a good idea to collect a large number of bags before recycling them, as this makes it easier for those hauling the plastic to the recycling plant.
It is worth noting that plastic bag recycling is not always available in all areas, so it is important to check with local recycling guidelines and regulations. Some municipalities may have specific requirements for collection, such as placing all bags into one bag and tying it at the top. Reusing plastic bags at home or in-store is also an option to reduce waste.

Plastic bags can be recycled at some retail stores
Plastic bags are one of the most common sources of marine debris, often being mistaken as food by birds and fish. They are also the number one source of contamination in city curbside recycling programs. This is because they can fly into the air and get stuck in the machinery at recycling centres. Therefore, it is important to dispose of plastic bags correctly.
Before bringing plastic bags to a store, it is important to ensure they are clean and dry, without any residue, stickers, or crumbs inside. This is required by local sanitation departments and recycling centres, and it ensures that the plastic can be recycled effectively without contaminating other materials. It is also more efficient to bring a large number of bags to recycle at once, as this makes it easier for those hauling the plastic from the bin to the recycling plant.
If you are unable to recycle your plastic bags at a retail store, there are other options. You can contact your local sanitation/recycling plant and ask if they accept plastic bags for recycling, or if they know of any nearby recycling centres that do. You can also reuse plastic bags around your home, for example, to wrap knick-knacks or to cart around other items.

Plastic bags can be returned to the store where they were purchased
Plastic bags are a major source of pollution and are harmful to marine life. While they can be recycled, they are not accepted in most curbside recycling programs. This is because they tend to get stuck in recycling equipment, causing the machinery to jam and requiring workers to shut down the machinery and remove the bags manually. Therefore, plastic bags should be recycled through specific plastic bag recycling programs.
Plastic bags can often be returned to the store where they were purchased for recycling. Many grocery stores and big-box stores have bins set up to collect plastic bags for recycling. Some dry cleaners and drugstores also offer this service. These bins are usually located near the front entrance of the store. Before returning the bags to the store, it is important to ensure that they are clean and free of any dirt, food particles, receipts, stickers, or other contaminants. It is also recommended to collect a decent number of bags before returning them to the store, as this makes it easier for those hauling the plastic from the bin to the recycling plant.
Some municipalities also accept plastic bags in their curbside collection programs, but this is not common. It is important to check with your local municipality to understand their specific requirements for plastic bag recycling. If your municipality does not accept plastic bags in their curbside collection, you may need to drop them off at a local grocery store or recycling facility. There are also online resources, such as recycling locators, that can help you find a location near you that accepts plastic bags for recycling.
It is worth noting that black plastic bags are harder to recycle and may be omitted from store collection bins due to the dye used, which limits their reprocessing options. Additionally, it is important to recycle plastic bags properly and not place them in your home recycling bin unless specifically instructed to do so by your local guidelines.
