It is important to clean recyclables before throwing them in the bin. While guidelines vary by location, contaminants can ruin certain recycling processes. For instance, even a small bit of oil or grease can ruin an entire load of paper recyclables. For plastic bags, it is important to ensure they are clean and dry before recycling, as wet or dirty plastic bags can make a whole bale of plastic musty and non-recyclable.

What You'll Learn
Plastic bags and films should be clean and dry
It is important to keep plastic bags and films clean and dry before recycling them. This is because contaminants can ruin the recycling process. While a small amount of residue on plastic bags and films may not make a huge difference, it adds up. Even a small bit of oil or grease can ruin the entire load of paper recyclables.
To clean plastic bags and films, simply give them a rinse, even with dishwater runoff. This will ensure that they get processed. It is important to note that you should never use soap or new water to clean recyclables. Using clean, warm water to rinse the items will negate the "green" effect.
It is also important to make sure that plastic bags and films are completely dry before recycling them. This is because excess water can interfere with the melting process during recycling.
In most cases, you cannot put plastic bags and films in your curbside bin as they will jam the machinery at the recycling facility. However, you can usually find bins to drop off your plastic bags for recycling in many supermarkets and big-box stores. As always, please check your local recycling guidelines.

A quick rinse is enough for plastic containers
It is important to rinse your plastic containers before recycling them. While guidelines vary depending on your location, a quick rinse is usually enough to ensure your plastic containers are adequately cleaned for recycling.
You do not need to scrub your plastic containers with soap and water until they are spotless. Instead, a quick rinse with water will do the trick. If you are concerned about wasting water, you can reuse dishwater or use water from the final rinse cycle of your dishwasher. You can also soak your containers in water overnight and give them a quick rinse the next day. This will help loosen any stubborn residue.
It is also worth noting that some facilities use forced air to separate plastics, so ensuring your containers are relatively clean will prevent any leftover gunk from messing up the process. Additionally, giving your containers a quick rinse will help keep your recycling bin clean and pest-free.
However, it is essential to check with your local recycling guidelines, as some facilities may have specific requirements. For example, some facilities may require you to remove food residue, while others may accept items with minor residue or stains.

Local recycling guidelines vary
In some areas, recycling points will refuse unwashed items. For example, in Santiago, Chile, greasy pizza boxes will be refused. However, in other areas, a quick rinse is adequate. For example, in Chicago, a quick rinse is fine, and there is no need to scrub containers with soap and water.
It is important to remove the bulk of food residue from recyclables. While a drop of yogurt or egg might not make a huge difference, it adds up. Even a small bit of oil or grease can ruin an entire load of paper recyclables. A quick rinse will ensure that items get processed and are not rejected.
It is also important to ensure that recyclables are dry. Wet and moldy paper, for example, is difficult to recycle. Plastic bags and film should also be dry and clean of residue.

Dirty plastic may be thrown out by recycling centres
It is important to ensure that plastic items are adequately cleaned before being placed in the recycling bin. While a single raindrop won't ruin a cardboard box, contaminants can hinder the recycling process. For instance, a small bit of oil or grease can ruin an entire load of paper recyclables. Similarly, dirty containers can contaminate an entire batch of recycling.
Recycling facilities have different requirements, and some may reject unwashed items. For example, some recycling centres in Santiago, Chile, will refuse unwashed items, especially greasy pizza boxes. This is because organic matter left on plastic, tins, and other materials is considered contamination. While a certain level of contamination is acceptable (20% is the national average in Chile), recycling centres want to keep it as low as possible.
Contamination can also occur when soiled, damp, or mouldy food containers are mixed with paper and cardboard. Substances like salad dressing can spill and spread to every dry item in the dumpster. When paper and cardboard get wet, their fibres can become brittle and crumbly, reducing their recyclability.
Therefore, it is essential to empty and rinse plastic containers before placing them in the recycling bin. A quick rinse is usually sufficient, and there is no need to use soap or "new" water. Reusing dishwater can make the process more environmentally friendly. Additionally, it is important to ensure that items are dry before recycling, as excess water can interfere with the melting process.

Clean plastic reduces the risk of pests
Clean plastic is essential to reduce the risk of pests. Plastic pollution is a significant environmental concern, endangering natural ecosystems and all living creatures on Earth. It has polluted the sea and land, posing a serious danger to marine life. Animals can get entangled in plastic trash or mistake it for food, leading to ingestion. Plastic's high resistance to decomposition further exacerbates the problem, as it can take hundreds of years to degrade fully while simultaneously leaching toxic chemicals.
To address this issue, it is crucial to recycle plastic properly and keep it clean. Contaminants can hinder the recycling process and attract pests. While guidelines vary by location, it is generally recommended to give plastic containers a quick rinse before recycling. This helps remove food residue, such as sticky substances like yogurt or more problematic substances like oil or grease, which can ruin an entire load of paper recyclables.
The presence of pests in plastic waste is a growing concern. Insects and microorganisms have been found to play a role in the degradation of polymer plastics. For example, the larvae of the pest Spodoptera frugiperda can survive by consuming PVC film, and certain bacterial strains isolated from larval intestines can depolymerize PVC. However, the precise manner in which insects degrade plastics is not yet fully understood, and the toxicological risks associated with plastic-eating insects require further investigation.
To minimize the risk of pests, it is important to keep plastic clean and free of food residue. While a drop of yogurt or a small amount of oil may seem insignificant, it can add up and attract unwanted insects. By taking the time to rinse plastic containers before recycling, you can help ensure that they are properly processed and reduce the risk of pest infestation.
Additionally, it is worth noting that reducing plastic use is the most effective way to address plastic pollution. Single-use plastics, in particular, contribute significantly to the problem. By opting for reusable alternatives, such as carrying a reusable bottle or tote bag, individuals can make a significant impact in reducing plastic waste and minimizing the risk of pest issues associated with plastic pollution.
