Plastic bags are a major source of pollution, taking hundreds of years to decompose in landfills and often ending up in oceans, where they can be mistaken for food by marine life. While plastic bags can be recycled, they cannot be placed in most curbside recycling bins as they jam the recycling machinery. Instead, plastic bags should be recycled at retail stores, which often have recycling bins specifically for plastic bags. These stores then send the bags to recycling facilities, where they are turned into plastic pellets and sold to manufacturers for reuse.
| Characteristics | Values |
|---|---|
| Plastic bag composition | Most plastic bags are made from high-density polyethylene (#2 plastic), while thinner-material bags (such as produce bags) are made from low-density polyethylene (#4 plastic) |
| Plastic bag recycling process | Plastic bag recycling involves chipping the bags into pellets, which can then be reprocessed into new bags or other products like composite decking, fencing, benches, etc. |
| Recycling collection | National grocery retailers and many smaller retailers offer bag recycling collections, usually through collection bins at their stores. |
| Curbside recycling | Plastic bags are not accepted through most local curbside recycling programs due to their flexible material, which can clog recycling machinery. However, there are a handful of curbside programs that accept plastic bags. |
| Contamination prevention | Ensure that any bags being recycled are clean and free of food, receipts, stickers, crumbs, and other contaminants. Remove sticky labels if possible. |
| Biodegradability | Plastic bags don't biodegrade, meaning they will take hundreds of years to decompose in a landfill. |
| Eco-friendly alternatives | Reusable bags are a more eco-friendly alternative to single-use plastic bags, as they last longer and reduce waste. |
| Plastic bag colour | Black plastic bags are harder to recycle as the dyed plastic produces dark pellets, limiting reprocessing options. |

Plastic bags are not accepted in most local curbside recycling programs due to their flexible material
Plastic bags are not accepted in most local curbside recycling programs. This is due to their flexible material, which can cause them to get stuck in recycling equipment and cause downtime, wasting time and money. In addition, plastic bags are often mistaken as food by birds and fish, becoming a common source of marine debris.
However, plastic bags can be recycled at thousands of retail stores and drop-off centers, including most local grocery stores. Major retailers such as Kroger, Safeway, Target, and Walmart offer bag recycling collections, usually located near the front entrance. Some municipalities also accept plastic bags in their curbside collection programs, but they typically require residents to put all bags into one bag and tie it at the top for easy removal before they reach the sorting machine.
Before recycling plastic bags, it is important to ensure they are clean and dry, free of any food residue, stickers, labels, staples, or receipts, as these can contaminate the entire batch. The bags should also be ripped open and discarded at recycling facilities, with recyclables dumped out and reused if possible.
Recycled plastic bags are typically turned into plastic pellets, which can then be used to create new products such as synthetic lumber for decking or park benches, or recycled directly into another film, pouch, or bag form. Some companies, like Trex, use recycled plastic to create plastic lumber for decks, fences, and other outdoor uses.

Plastic bags are among the most common sources of marine debris, often mistaken as food by birds and fish
Plastic bags are a major contributor to marine debris, with their lightweight and durable properties making them likely to be swept out to sea. Once in the ocean, plastic bags can cause significant harm to marine life. Birds and fish are particularly susceptible to mistaking plastic bags for food.
Plastic bags are often consumed by marine birds, who may mistake them for prey items such as fish or squid. This can lead to serious health issues, including internal injuries, intestinal blockages, and even death. The problem is widespread, with studies finding plastic in the stomachs of over 80% of birds in the 1980s, a sharp increase from less than 5% in the 1960s. It is projected that by 2050, almost every seabird species will be ingesting plastic.
Young birds are especially vulnerable to plastic ingestion as they are fed plastic by their parents, who mistake it for food. This reduces the chicks' stomach volume, leading to starvation and a decreased likelihood of survival to adulthood. Additionally, plastic ingestion has been linked to smaller body sizes, shorter wings and bills, and reduced kidney function in adult seabirds.
Plastic bags can also harm fish and other marine life. As plastic breaks down into smaller pieces, it can be ingested by tiny zooplankton, which are then eaten by larger creatures such as oysters, scallops, mussels, and fish. These small plastic particles can accumulate in the bodies of marine organisms and move up the food chain, eventually reaching top predators such as seals, sharks, and dolphins.
To address the issue of plastic bags in marine environments, it is essential to reduce their use and properly recycle them. Many grocery stores and retailers offer plastic bag recycling collections, and some communities have implemented bag bans or taxes to discourage their use. By increasing awareness, improving waste management practices, and adopting reusable alternatives, we can help reduce the impact of plastic bags on marine ecosystems and the wildlife that inhabits them.

Black plastic bags are harder to recycle due to the dye used, limiting reprocessing options
Plastic bags are a major source of pollution, often ending up in oceans and contributing to marine debris. They are also commonly mistaken as food by birds and fish. While plastic bags cannot biodegrade, they can be recycled and are widely recycled through collection bins at grocery stores. However, black plastic bags pose a unique challenge due to the dye used in their production.
Black plastic bags are dyed with carbon black, a pigment that is not detectable by near-infrared technology used at many material recovery facilities (MRFs) for sorting recyclables. As a result, black plastic items often pass by undetected and are not diverted for recycling. Instead, they end up in landfills.
The use of carbon black pigment limits the reprocessing options for black plastic. When black plastic bags are recycled, they produce dark pellets, which can only be reprocessed into other dark-coloured items. This restricts the potential applications for the recycled material.
To address the issue of black plastic bags ending up in landfills, consumers can take several actions. Firstly, it is recommended to choose products packaged in clear or light-coloured plastic, as these are more easily recyclable. Consumers can also advocate for less use of carbon black plastic and encourage companies to minimise its use in their packaging. Repurposing and reusing black plastic items is another way to extend their life and delay their disposal.
Some communities and states have implemented bag bans or bag taxes to reduce the use of plastic bags. Additionally, some retailers who distribute bags are mandated to accept them for recycling. These measures aim to minimise the environmental impact of plastic bags and promote more sustainable alternatives.

Plastic bag recycling involves chipping the bags into pellets, which are then reprocessed into new bags or plastic lumber
Plastic bags are not accepted in most curbside recycling bins. They often get stuck in recycling equipment and cause contamination. However, there are thousands of retail stores and drop-off centres that accept plastic bags for recycling. Major retailers like Kroger, Safeway, Target, and Walmart offer bag recycling collections in their stores.
Once collected, plastic bag recycling involves chipping the bags into pellets. These pellets can be reprocessed into new bags, but they are more likely to be manufactured into plastic lumber. This is because plastic lumber is more durable and can be used for outdoor purposes like decks, fences, and park benches. One of the largest recyclers of plastic bags is Trex, which uses recycled plastic to create composite lumber for outdoor use.
To recycle plastic bags, it is important to first rip them open and discard them at recycling facilities. Then, the flexible plastic is baled and sold to independent companies. These companies turn the plastic films into pellets, which can be used to create new products.
While plastic bag recycling is important, it is also crucial to reduce the use of single-use plastic bags and switch to reusable alternatives whenever possible. This helps to minimize the environmental impact of plastic waste and contributes to a more sustainable future.

Similarly, Safeway and T&C grocery stores have plastic bag recycling receptacles at the entrance to their stores, where customers can deposit not just plastic bags but also other kinds of plastic film. Walmart, on the other hand, has been continuously improving its efforts to help with plastic reduction and recycling strategies. The company has expanded the assortment of reusable bags offered at checkouts, with prices starting at 74 cents. They have also participated in pilot programs like the Beyond the Bag initiative, a three-year project with companies like Target and CVS Health, to explore more sustainable solutions. Walmart supports the adoption of a Global Plastics Treaty and works with leading experts and non-governmental organizations to advocate for well-constructed, science-based policies that can help accelerate the availability and adoption of more sustainable packaging solutions.
