Compostable plastics are designed to biodegrade into soil-conditioning material, also known as compost. The best way to dispose of compostable plastics is to send them to an industrial or commercial composting facility where they can break down with the right mixture of heat, microbes, and time. If your community does not have a composting recycling pick-up program, you can contact your local government or garbage/recycling company to find out if there are any drop-off locations for compostable plastic items. Some cities, like Washington, D.C., offer food waste drop-off programs that accept compostable food serviceware and packaging. However, it's important to note that compostable plastics cannot be recycled and should not be placed in recycling bins.

Compostable plastics should be sent to industrial or commercial composting facilities
Compostable plastics are designed to biodegrade into soil-conditioning material, also known as compost. They are transformed into a polymer that looks and feels like traditional plastic. However, they are typically made from some type of renewable raw material, such as corn starch.
The best way to dispose of compostable plastics is to send them to an industrial or commercial composting facility. Here, they will break down with the right mixture of heat, microbes, and time. These facilities are specifically designed to handle the unique requirements of composting plastics, including providing the necessary high heat for a sustained period.
It is important to note that most backyard compost piles do not get hot enough to effectively compost these plastics. Even some industrial or commercial compost facilities may not maintain the required temperature for long enough to fully degrade the plastic. Therefore, it is essential to identify facilities that meet the specific guidelines for composting plastics.
If your community does not have a composting recycling program that accepts compostable plastic, you can contact your local garbage/recycling company or local government to inquire about any drop-off locations for these items. Some cities, like Washington, D.C., offer food waste drop-off programs that accept compostable items, including certain compostable plastics. Additionally, some retailers sponsor programs that collect plastic bags and other flexible plastic packaging in their stores.
It is important to distinguish compostable plastics from regular plastics to ensure proper disposal. Look for certification labels from organizations like the Biodegradable Products Institute, which certifies products for commercial composting facilities.

If no such facility is available, compostable plastics should be thrown in the trash
Compostable plastics are designed to biodegrade into soil-conditioning material, also known as compost. The best way to dispose of them is to send them to an industrial or commercial composting facility where they can break down with the right mixture of heat, microbes, and time.
However, if no such facility is available in your area, the only option is to throw them in the trash. Compostable plastics are typically made from renewable raw materials, such as corn starch, and are transformed into a polymer that looks and feels like traditional plastic. While compostable, these items are not intended for recycling and can contaminate and disrupt the recycling stream if mixed with non-compostable plastics. Therefore, it is important to dispose of them properly.
If your community does not offer a composting pick-up program or have drop-off locations for compostable plastics, contact your garbage/recycling company or local government to see if there are any other options available. Some communities may provide collection bins in public spaces for certain types of flexible plastic films. Additionally, some retailers sponsor programs that collect plastic bags and flexible plastic packaging in their stores.
It is important to note that the composting process requires oxygen, and landfills are typically sealed, oxygen-free containers. Therefore, compostable items thrown in the trash may not break down as intended. Some studies suggest that compostable materials in landfills can release methane, a potent greenhouse gas, while others find that these materials do not break down at all and do not contribute significantly to greenhouse gas emissions.
While it is preferable to compost these items when possible, the debate about the environmental impact of compostable plastics ending up in landfills is ongoing. Some argue that even if compostable materials wind up in landfills, they are still better for the environment than conventional plastics because they are made from renewable resources and may have less toxicity.

Compostable plastics cannot be recycled
Compostable plastics are typically made from renewable raw materials, such as corn starch, seaweed, sugar beets, or other plants, instead of fossil fuels. However, they cannot be recycled with other plastics because they will contaminate and disrupt the recycling stream if intermixed with petroleum-based plastics that are non-compostable. Therefore, it is important to separate compostable plastics from other recyclables and dispose of them properly.
If your community does not have a composting recycling pick-up program that accepts compostable plastic, you should contact your garbage or recycling company, or local government, to find out if there are any drop-off locations for compostable plastic items. Some communities have residential compost collection programs that accept compostable plastic, so it is worth checking with your local government or recycling company to find out.
It is important to note that not all compostable plastics are created equal. To be certified as compostable, plastics must meet specific guidelines set by organizations like the American Society for Testing and Materials (ASTM International). These guidelines ensure that the plastic can break down within six months in a commercial or industrial composting facility without leaving any toxic residue that could harm plant growth.
Therefore, it is crucial to read the product's label to determine its compostability and recyclability. While compostable plastics are designed to biodegrade, they require specific conditions, such as high heat for a sustained period, that are not typically found in backyard compost piles or even some industrial compost facilities. As a result, compostable plastics may not fully degrade and can end up contributing to plastic pollution if not disposed of properly.

Compostable plastics are made from renewable materials
Compostable plastics are designed to biodegrade into soil-conditioning material, also known as compost. They are typically made from some type of renewable raw material. Corn starch is one of the most common materials, but there are many other options, including seaweed, sugar beets, and other plants.
To dispose of compostable plastics, it is best to send them to an industrial or commercial composting facility where they can break down with the right mixture of heat, microbes, and time. If this type of composting facility is not available in your area, you may need to throw compostable plastics in the trash.
Some materials can be composted at home, but it is important to check for a "`home compostable` label before doing so. Many commercial composters do not accept compostable plastic items, even if they are certified as compostable. Compostable and biodegradable plastics can contaminate the recycling stream, so it is important to only recycle items that your local program accepts.
The American Society for Testing and Materials (ASTM International) has published specific guidelines that must be met for a material to be labeled as commercially compostable. These guidelines include the ability to break down through biological treatment at a commercial or industrial composting facility, decomposition within six months, and leaving no toxic residue that could harm plant growth.
The development of biodegradable plastics from renewable natural resources has the potential to offer sustainability and environmental benefits. However, it is important to note that biodegradable and compostable plastics are not always the more sustainable option. Proper waste management is crucial to ensure these materials break down as intended and do not contribute to plastic pollution.

Compostable plastics should be dropped off loose in the bin or in compostable bags
Compostable plastics are designed to biodegrade into soil conditioning material, also known as compost. The best way to dispose of compostable plastics is to send them to an industrial or commercial composting facility where they can break down with the right mixture of heat, microbes, and time.
If your community has a composting recycling pick-up program, you can dispose of your compostable plastics there. If not, contact your garbage/recycling company or local government to find out if there are any drop-off locations for compostable plastic items.
In Washington, DC, for example, residents can drop off food waste and food-soiled paper for composting at 24/7-accessible Food Waste Smart Bins and weekend drop-off events in all eight wards. All collected food waste is taken to nearby composting facilities. It is important to note that everything dropped off into a food waste bin must be compostable, and only compostable bin liners, such as brown paper bags or BPI-certified compostable bioplastic liners, are accepted.
When dropping off compostable plastics, ensure that they are loose in the bin or placed in compostable bags. This is because compostable or not, flexible film plastics should never be placed in traditional recycling bins as they can quickly become tangled and damage recycling equipment at sorting facilities.
If a composting facility is not available in your area, the only option is to throw compostable plastics in the trash. However, this is not ideal as compostable items in landfills may not break down properly and can release methane, a greenhouse gas.
