Compostable plastic is not recyclable and can contaminate recycling streams
Compostable plastic is a relatively new innovation that has gained widespread attention and use as a promising solution to the global plastic problem. However, the reality is that compostable plastic is not a perfect solution. One of the main issues is that compostable plastic is not recyclable. In fact, if compostable plastic is mixed with non-compostable plastic, it can contaminate and disrupt the recycling stream. This is because compostable and non-compostable plastics have different chemical structures, and they cannot be recycled together. Therefore, it is important to keep compostable plastics separate from other recyclables.
To properly dispose of compostable plastic, it must be sent to an industrial composting facility. These facilities create the specific conditions, including pH, moisture levels, temperature, and microbial activity, that are necessary for compostable plastic to break down safely. At these facilities, compostable plastic can be transformed into compost, a valuable soil amendment that benefits soil health and the environment.
However, one of the main challenges with compostable plastic is the lack of standardisation and clear labelling. In many places, there are no regulations on how compostable products can be marketed, and consumers may not be able to tell the difference between compostable and non-compostable plastic. This leads to confusion about how to properly dispose of compostable plastic, and many people end up putting it in the recycling bin or garbage can. To address this issue, governments and companies need to work together to create and follow guidelines for the labelling and identification of compostable products.
In conclusion, compostable plastic is not recyclable and can contaminate recycling streams if not disposed of properly. To reduce contamination, it is important to keep compostable plastic separate from other recyclables and to send it to an industrial composting facility. Additionally, proper labelling and consumer education are key to ensuring that compostable plastic is disposed of correctly and can have a positive impact on the environment.

Check local programs to see what is accepted for curbside recycling
It is important to check local programs to see what is accepted for curbside recycling, as programs vary from community to community. Local programs may have different rules, so it is always worth checking with your local recycling provider to learn if they accept certain items. Your community's recycling website is a great resource to find information on your specific program.
For example, in some areas, glass containers are recycled domestically, mainly into wine bottles. However, broken glass should not be placed in recycling bins, as it can harm workers and damage equipment. Similarly, metal bottle caps should be recycled separately from glass bottles. Most curbside recycling programs accept different colours and types of glass mixed together, and then the glass is sorted at the recovery facility.
Another example is plastic. Plastic containers and rigid plastic are generally recycled in the Pacific Rim. However, it is important to separate plastic types to increase the market value of the material. Additionally, some corn-based plastic products are not recyclable or compostable locally.
Finally, it is worth noting that some items, such as lead-acid batteries and rechargeable batteries, should not be placed in the trash or municipal recycling bins. Instead, they should be returned to a battery retailer or local household hazardous waste collection program.

Compostable plastic is designed to break down in specific conditions
Compostable plastic is a promising solution to the global plastic problem. However, it is important to understand that compostable plastic is not designed to break down just anywhere. It is designed to break down in specific conditions, and if not managed properly, it may not break down as intended.
The term "biodegradable" is often used for marketing purposes, with a time component included to indicate how long it takes for the plastic to fully degrade. According to the Federal Trade Commission's "Green Guides," it is deceptive to make an unqualified degradable claim for items entering solid waste streams if they do not completely decompose within a year. However, nature does not have controlled conditions, and it is challenging to determine if biodegradable plastic will actually biodegrade in the natural world if it is littered.
Compostable plastic, on the other hand, is designed with specific conditions in mind, such as pH, moisture levels, temperature, and microbial activity. These conditions are typically found in industrial or commercial composting facilities, which have higher temperatures and different breakdown conditions than those in a typical homeowner's compost bin. The specific conditions enable compostable plastic to transform into usable soil conditioners, contributing positively to the environment.
To ensure proper disposal, it is important to check the labels on compostable plastic items. If the label indicates that the product is suitable for home composting, it can be composted at home. Otherwise, it should be sent to an industrial or commercial composting facility. Additionally, it is crucial to check with local guidelines, as some municipalities may have specific instructions for disposing of compostable plastic.
While compostable plastic offers a potential solution to waste management, it is not a cure-all for the plastic pollution crisis. Proper collection and recovery systems are necessary to ensure that compostable plastic stays out of nature.

Curbside composting is a separate collection service
To start composting curbside, you can use any bin with a secure lid and a capacity of up to 55 gallons. You can order a free Composting Bin label for your bin from nyc.gov/CompostingBinDecal, or you can purchase brown bins at bins.nyc. It is recommended that you line your bin with a clear plastic, paper, or compostable bag to keep it clean. Avoid using black plastic bags. You can also use small plastic, paper, or compostable bags inside the liner to dispose of daily food scraps.
Food scraps, food-soiled paper, and yard waste are all compostable. To reduce odors, drain liquids before placing materials in the bin, and use paper or baking soda at the bottom of your bin to absorb excess moisture. You can also put food scraps in your freezer before emptying them into your compost bin. Tie the bag closed before putting the bin out for collection.
Curbside composting is an environmentally beneficial way to reduce organic waste sent to landfills. It also helps keep your home and neighborhood clean and healthy by reducing odors and the chance of bags breaking open on the curb, which can cause litter and attract pests.

Compostable plastic is not suitable for home composting
The Big Compost Experiment, a citizen science project conducted by University College London, found that biodegradable and compostable plastic packaging cannot be effectively composted at home. The experiment involved 9,701 UK citizens taking an online attitudes survey, with 1,648 of them performing home composting experiments on compostable plastics. The results showed that compostable and biodegradable plastics do not fully degrade in home composting conditions, even those certified as home compostable.
One issue with home composting of plastics is the lack of regulation and standardisation. Organic waste that undergoes industrial composting can obtain legal 'end-of-waste' status, whereas home composting is unregulated. This makes it challenging to ensure the effective composting of plastics in home settings. Additionally, there is confusion among consumers about appropriate disposal routes, with many not understanding the distinction between items suitable for home composting versus industrial composting.
The potential impact on the food chain and human health is another concern. Microplastics, inks, and glues used in compostable packaging can have negative effects on ecosystems and human health. Studies have found that microplastics can be taken up by plants and detected in human blood, impacting the local ecology and food chain. Therefore, it is crucial to correctly identify which items are suitable for home composting to minimise these risks.
Furthermore, the market for compostable materials is not well-controlled, and there is a lack of across-the-board standards. Compost processors need a guarantee that compostable plastics will actually break down and not contaminate the compost. While there are efforts to improve labelling regulations, it is currently recommended not to put compostable plastics in municipal compost bins. Instead, they often need to be disposed of in the garbage.
