Plastic recycling is crucial for our future. Recycling allows for the reutilization of materials, reducing the need for new raw materials, decreasing greenhouse gas emissions, and minimizing the negative impact on the environment. Number 4 plastic, or LDPE (Low-Density Polyethylene), is used in bags, films, and lighter plastics. While some retailers accept LDPE for recycling, it is not always clear which plastic types they take. To find out where to recycle number 4 plastic in your area, you can use online recycling locators, such as Earth911's Recycling Locator, which allows you to search by zip code. Trex, the largest recycler of plastic bags in the USA, also accepts number 4 plastic bags and films. Additionally, some cities like San Jose, California, offer plastic recycling services, but they may have specific requirements for the types and quantities of plastic they accept.

What You'll Learn

Plastic bags
Although plastic bag recycling is possible, it is not generally recycled. Plastic bags can get tangled in the equipment at recycling facilities, and black plastic bags are harder to recycle because the plastic is dyed, limiting reprocessing options. In the US, plastic bags, wraps, and films are not accepted in most curbside or drop-off programs. However, many of these packages are eligible for store drop-off recycling, and some grocery stores collect plastic bags for proper recycling.
If you are looking to recycle plastic bags, you can use a recycling locator to find a location near you. You can also contact your local sanitation/recycling plant and ask if they accept #4 plastic for recycling or if they know of any nearby recycling centers or organizations that do.
To prepare plastic bags for recycling, ensure that they are clean and dry, remove any receipts, stickers, or crumbs, and keep them in a collection bin in your house until you have a sufficient number to recycle.

Retailers that accept #4 plastic
#4 plastic, also known as low-density polyethylene (LDPE), is commonly used in plastic bags, plastic wrapping, and cling film. While LDPE is not often recycled through curbside programs, some communities may accept it. It is important to check with your local municipality's recycling guidelines to determine if #4 plastic is accepted in your area.
If your community does not accept #4 plastic, there are other options for responsible disposal. Many grocery chains, big-box stores, and smaller retailers have bins set up to collect plastic bags for recycling. These include national retailers such as Kroger, Safeway, Target, and Walmart, which typically place their recycling bins near the front entrance.
Additionally, you can return #4 plastic bags to the store where you originally purchased them, as many grocery stores collect these bags for proper recycling. Smaller grocery retailers may also accept plastic bags for recycling, but it is always a good idea to check with the store before bringing in your bags.
It is important to ensure that your plastic bags are clean and dry before recycling them. This helps to prevent the growth of bacteria and keeps the bags from becoming contaminated. By recycling #4 plastic responsibly, you can do your part to reduce plastic waste and protect the environment.

Low-density polyethylene
LDPE is not widely recycled, and most LDPE products end up in landfills. In 2015, just 6.2% of LDPE generated that year was recycled. This is due in part to the fact that LDPE can be difficult to recycle; it has a tendency to tangle in recycling machinery, requiring routine stoppages and removal. As a result, many municipalities and recycling programs do not accept LDPE, especially soft and flexible LDPE like cling film and plastic bags.
However, recycling LDPE is possible and can be done through certain grocery store drop-off programs and licensed waste carriers. Some grocery stores set up collection bins where customers can return used LDPE bags, and some supermarkets, including Safeway and Lucky Food Centers in the US and Canada, accept LDPE plastic bags for recycling. Licensed waste carriers can also remove and replace bins for LDPE waste on a daily, weekly, or fortnightly basis.
To find a recycling location near you that accepts LDPE, you can use online recycling locators like Earth911, which allows you to search by zip code to find stores that take LDPE for recycling.

Recycling information in your state
Recycling information varies from state to state, and even from one local community to another. It is always best to check with your local recycling program to see what types of plastic they collect.
Plastic #4, or LDPE (low-density polyethylene), is used in a variety of consumer goods, including plastic bags, films, coatings in paper cups and cartons, and shrink wrap. Many local curbside recycling programs do accept LDPE plastics, but it is always best to check with your local program first. Some programs accept items like milk cartons and food container lids, but not LDPE plastic bags, so be sure to clarify which items are accepted.
Retail locations, such as grocery stores, often have collection bins for LDPE plastic bags. It is important to keep these bags separate from other plastics and ensure they are clean and dry before placing them in the recycling bin. It is also worth noting that black plastic bags are harder to recycle and are sometimes omitted from store collection bins because the dyed plastic produces dark pellets, limiting reprocessing options.
If you are unable to find a local recycling option for plastic #4, there are mail-in recycling programs available. Earth911.com provides a recycling locator that allows you to search for recycling options by zip code. This can help you find stores or other locations that accept LDPE plastics for recycling.
It is important to note that not all plastics are created equal when it comes to recycling. Some plastics, like polystyrene (#6), are not generally recyclable and can be harmful to human health and the environment. On the other hand, some plastics, like PET (#1), are safe for single-use recycling but should be avoided for reuse due to the risk of bacterial growth and chemical leaching.
