Plastic bags are a major source of pollution and are harmful to the environment. They are known to cause havoc for machinery at recycling centers and are not easily recyclable. Biodegradable bags are also known to contain non-plastic materials that become contaminants in the recycling stream. They are also not always as eco-friendly as they seem and may leave behind toxic chemicals. However, some biodegradable bags can be recycled, but it depends on their chemical structure. Compostable plastics, for example, are designed to break down under specific composting conditions and cannot be recycled in the same way as other plastics. It is important to check the labels and guidelines for recycling biodegradable bags and understand the difference between biodegradable and compostable bags.
| Characteristics | Values |
|---|---|
| Recyclability | Biodegradable plastic bags cannot be recycled with other plastics due to chemical structure incompatibility. |
| Compostability | Biodegradable bags are not compostable and should not be put in a compost pile as they may stop breaking down before they finish degrading. |
| Environmental impact | Biodegradable bags are marketed as eco-friendly but may not degrade as advertised and can leave toxic chemicals behind. They are also blown into creeks, lakes, or oceans, where they can entangle marine life or be mistaken for food. |
| Raw materials | Biodegradable bags require more raw materials to produce and discourage the use of reusable or recyclable options. |
| Reuse | Biodegradable bags should be reused instead of recycled or thrown away. |
| Recycling process | Biodegradable bags cannot be recycled with other plastics and must be separated. |
| Collection | Biodegradable bags should not be put in curbside recycling bins or home recycling bins. They can be recycled at some local grocery stores or recycling facilities. |

What You'll Learn
Biodegradable bags are not always eco-friendly
Biodegradable plastic bags are often marketed as eco-friendly solutions that can break down into harmless material more quickly than traditional plastics. However, the reality is that these bags are not always as environmentally friendly as claimed.
Firstly, biodegradable bags are challenging to recycle and can contaminate the recycling stream. They cannot be recycled with other plastics and can ruin batches of recyclable plastic, making the final product unusable. Most recycling facilities are not equipped to process plastic bags, and they can jam machinery, requiring manual intervention and causing downtime. As a result, many recycling plants are not interested in dealing with plastic bags, and they often end up in landfills.
Secondly, biodegradable bags may not break down as effectively as claimed. In a study, biodegradable bags were tested in various environments, including being buried in soil, submerged in water, and exposed to open light and air. After three years, none of the bags had completely broken down, and some could still hold a full load of groceries. This indicates that even if biodegradable bags end up as litter, they can still have the same negative environmental impact as their non-biodegradable counterparts, contributing to the plastic pollution crisis.
Additionally, compostable bags, which are a type of biodegradable bag, have their own set of challenges. Compostable bags need to be industrially composted under specific temperature and bacterial conditions to effectively degrade. However, due to a lack of composting infrastructure, many of these bags do not end up in proper composting facilities. Instead, they are sent to landfills, where they can persist for extended periods, or they are incinerated, which has its own environmental implications.
Furthermore, biodegradable bags are often made from bio-based sources such as plants. While this may seem more environmentally friendly, bio-based plastics can be designed to be structurally identical to petroleum-based plastics. In such cases, they can last in the environment for just as long as traditional plastics.
In conclusion, while the concept of biodegradable bags is appealing, they are not a panacea to the plastic pollution crisis. To truly reduce our environmental impact, we must focus on reducing, reusing, and recycling plastic, as well as shifting towards more sustainable alternatives and circular economic models.

Plastic bags can be recycled at some major retailers
Plastic bags are a major source of pollution, especially in waterways, and can be extremely harmful to wildlife. They are also a significant cause of recycling machinery jams. Due to these reasons, many communities have banned single-use plastic bags, and some have mandated that retailers who distribute plastic bags must accept them for recycling.
Some major retailers that offer plastic bag recycling include Kroger, Safeway, Target, and Walmart. These retailers usually have plastic bag recycling bins located near the front entrance of their stores. Other retailers that offer plastic bag recycling include Home Depot and Harris Teeter.
When recycling plastic bags, it is important to ensure that the bags are clean, dry, and free of any contaminants such as stickers, staples, and receipts. It is also recommended to stuff all your plastic bags into one bag and tie it at the top, making it easier for recycling workers to handle.
Most drop-off bag collections accept polyethylene film, including high-density polyethylene (HDPE or #2 plastic) and low-density polyethylene (#4 plastic or LDPE). Plastic shopping bags from any store can be recycled, but it is important to remove any receipts or other contaminants before dropping them off.
By recycling plastic bags at these major retailers, individuals can play a crucial role in reducing plastic pollution and promoting a more sustainable environment.

Biobased plastics can be designed to be structurally identical to petroleum-based plastics
Plastic bags are typically made from petroleum-based plastic and are not biodegradable. They are lightweight and not easily recyclable. When disposed of on land, they can be blown into creeks, lakes, or oceans, where they can harm marine life. Plastic bags can also wreak havoc on recycling machines as they bend easily and get caught in conveyor belts, requiring manual labour to clear.
Biobased plastics are made from plant materials instead of oil or natural gas. They can be designed to be structurally identical to petroleum-based plastics, in which case they will last just as long in the environment. Biobased plastics can be engineered to be biodegradable or compostable. However, some forms of biobased plastic cannot be recycled with petroleum-based plastics due to chemical structure incompatibility.
The structural similarity between bioplastic and petroleum-based plastic is striking. Both contain polymers, but the source distinguishes them. Polylactic acid (PLA), a common bioplastic polymer, is made by fermenting plant starch from agricultural waste. The lactic acid molecules form long chains that become polymers. These polymers have molecular bonds that can be broken down by water, heat, and sunlight, making bioplastics more eco-friendly than regular plastic.
Bioplastics are being developed and tested as sustainable alternatives to single-use plastics for packaging, utensils, food containers, 3D printing, fashion, and medical implants.
While plastic bags are not commonly recycled through curbside collection, they can often be recycled at local grocery stores or other large businesses. Some municipalities also accept plastic bags for recycling. It is important to check with local guidelines and requirements before attempting to recycle plastic bags.

Biodegradable bags are not compostable
Biodegradable plastic bags are not necessarily compostable. Biobased plastics can be designed to be structurally identical to petroleum-based plastics, and if designed in this way, they can last in the environment for the same period of time as petroleum-based plastic.
Biodegradable bags are often marketed as a more environmentally friendly alternative to regular plastic bags. However, the term "biodegradable" is often used deceptively in marketing. According to the US Federal Trade Commission's "Green Guides", it is deceptive to claim that an item is biodegradable if it does not completely decompose within one year after disposal.
In a study conducted by British marine biologist Richard Thompson and his graduate students at Plymouth University, several biodegradable and compostable bags were placed in three different environments: immersed in water, buried in soil, or exposed to outdoor air (like litter). After long-term exposure to these environments, none of the bags fully decomposed. In fact, some of the bags could still hold 5 pounds of groceries, demonstrating that they had not substantially deteriorated.
The breakdown of biodegradable bags can also lead to the creation of microplastics, which can have negative environmental consequences. Additionally, biodegradable bags may not provide any environmental advantages over regular plastic bags in terms of reducing marine litter.
Therefore, it is important to understand that biodegradable bags are not compostable and may not provide the environmental benefits that are often claimed. It is essential to consider the full life cycle of these bags and the potential impact of their breakdown products on the environment.

Plastic bags are not accepted in curbside collections
Although a small number of communities do accept plastic bags in their curbside collections, the vast majority do not. In locations that do accept plastic bags in their curbside collection, there are often specific requirements for collection. For example, residents may be asked to put all bags into one bag and tie it at the top so that recycling workers can easily remove the bag before it goes into the sorting machine.
Plastic bags can be recycled at most local grocery stores, although it is not always clear what happens to the bags after they are dropped off. Some retailers have contracts with companies to supply recycled plastic lumber. However, it is generally recommended to bring your own reusable bags to the store as the most eco-friendly alternative.
Biodegradable plastic bags may be made from plant materials, but they can also be designed to be structurally identical to petroleum-based plastics, in which case they will last in the environment for the same amount of time. Some forms of biodegradable plastic cannot be recycled with petroleum-based plastics due to chemical structure incompatibility.
To recycle plastic bags, it is important to ensure they are clean and dry and free of any stickers, staples, or receipts. Plastic bags should not be placed inside other plastic bags for recycling, as this makes it difficult for facilities to sort the items and the bags may end up in landfills.
