What You'll Learn
Rinsing and sorting plastic containers
Rinsing Plastic Containers:
- Empty the containers: Before rinsing, make sure that your plastic containers are empty. Scrape out any remaining food or liquid residue to ensure they are as clean as possible.
- Rinse with water: Hold the container upside down under running water to give it a quick rinse. This will remove any remaining food particles or liquids. You don't need to scrub or use soap, just a quick rinse will do.
- Air-dry: After rinsing, allow the containers to air-dry before placing them in the recycling bin. You can set up a small drying area near your bin for this purpose.
Sorting Plastic Containers:
- Check for recycling symbols: Look for the recycling symbols on the containers to identify the type of plastic. Common symbols include the Mobius loop with a number inside (1 through 7), indicating the Plastic Resin Identification Codes. Understanding these symbols will help you sort the containers properly.
- Separate by type: Sort the containers into different piles according to their plastic type. For example, you can have separate piles for PET (polyethylene terephthalate) bottles, HDPE (high-density polyethylene) bottles, and other types of plastic.
- Handle caps and labels: Remove the caps or lids from the containers. Unless your local guidelines specify that you can recycle them, it's best to dispose of them in the trash, as they are usually made of a different type of plastic. There's no need to remove labels, as they will be separated during the recycling process.
Remember to always refer to your local guidelines or recycling service provider for specific instructions. Some areas may have different rules regarding which types of plastic they accept and how they should be prepared for recycling. By rinsing and sorting your plastic containers properly, you're not only reducing contamination but also increasing the value of the recyclables, supporting the economy, and contributing to a greener environment.

Plastic recycling symbols
- PETE/PET: This symbol represents Polyethylene Terephthalate, a clear, strong, and lightweight plastic commonly used for food and drink packaging, such as soda and water bottles, salad dressing bottles, and peanut butter containers. It is one of the most widely accepted plastics in curbside recycling programs.
- HDPE: High-Density Polyethylene is a common type of plastic found in household products like milk jugs, cleaning containers, shampoo, and detergent bottles. HDPE is lightweight but durable and can be easily recycled into new products like pens, toys, and outdoor furniture.
- PVC: Polyvinyl Chloride is identified by the number 3 with the letter "V". It is commonly found in bubble foils, trays for sweets and fruit, and expanded PVC foam board for commercial applications. PVC is rarely recycled and is usually not part of curbside recycling programs.
- LDPE: Low-Density Polyethylene is denoted by the number 4 with the acronym LDPE. This plastic is often used for shopping bags, highly-resistant sacks, and crushed bottles. LDPE is not typically recycled but can be converted into floor tiles and shipping envelopes.
- PP: Polypropylene, marked with the number 5 and the acronym PP, is known for its durability, strength, and low weight. It is used in furniture, luggage, toys, and the lining and external parts of cars. PP is increasingly being accepted in curbside recycling programs.
- PS: Styrene plastic, or Polystyrene, is identified by the number 6 with the acronym PS. This plastic is commonly used in toys, hard packing, refrigerator trays, cosmetic bags, costume jewelry, CD cases, and vending cups. While it is not accepted in many curbside recycling programs, polystyrene can be recycled into egg cartons, takeout containers, and rulers.
- OTHER: The number 7 with the word "OTHER" represents miscellaneous plastics that don't fit into the other six categories. These include acrylic, polycarbonate, polylactic fibers, nylon, and fiberglass. Products with this symbol may contain harmful chemicals like BPA and should be disposed of properly through drop-off centers or mail-in programs.

Plastic containers that are safe to recycle
When it comes to recycling plastic containers, it's important to know that not all plastics are created equal. Some plastics are readily recyclable with your household recycling collection or local recycling drop-off, while others require special handling or are not recyclable at all. Here are some guidelines for plastic containers that are generally safe to recycle:
Plastic Containers with a Resin Identification Code
Look for the resin identification code, usually a number from 1 to 7 enclosed in a triangle, on the container. This code helps recyclers identify the type of resin the plastic is made from. While not all curbside recyclers can process all types of plastic, having this code makes it easier for them to sort and separate the recyclables.
Single-Use Plastic Containers
Most single-use plastic containers, such as yogurt or fruit cups, are typically safe to put in household recycling bins, as long as they are clean and empty. Rinse the containers to remove any food residue and let them dry before placing them in the recycling bin.
Plastic Bottles and Jugs
Plastic bottles, including water bottles, cleaning product bottles, and shampoo bottles, are generally safe to recycle. Make sure to empty and rinse the bottles, especially if they contained hazardous substances like cleaning products. You can recycle the caps as well, but separate any spouts or pump tops and dispose of them in the trash.
Food Tubs
Food tubs, such as containers for sour cream, yogurt, and similar products, are usually recyclable at the curb or a drop-off location. Again, ensure that they are empty and clean before placing them in the recycling bin.
Plastic Jugs
Plastic jugs, including those used for milk and laundry detergent, are safe to recycle. Follow the same guidelines as for plastic bottles, ensuring they are empty, clean, and dry.
It's always a good idea to check with your local recycling guidelines, as practices can vary between different areas. Additionally, keep in mind that some facilities may have specific preferences or limitations for certain types of plastic.

Plastic containers that are unsafe to recycle
Plastic bags cannot be recycled, but some retail and grocery stores accept these materials. Plastic utensils are also not recyclable. Compostable plastics should not be recycled, as they can contaminate and disrupt the recycling stream if mixed with non-compostable plastics.
It is important to check with your local recycling program to learn which items are accepted. For example, very few localities accept styrofoam in curbside recycling, and some cities offer curbside composting for food-coated paper products.

The recycling process
Firstly, it is crucial to ensure that the plastic containers are empty, clean, and dry before placing them in a recycling bin. This reduces the risk of contamination, which can decrease the value of recyclable items. Giving items a quick rinse to remove food residue is often enough to prepare them for recycling. It is also important to separate different types of plastics, as they may have distinct recycling instructions. Familiarising oneself with the seven plastic recycling symbols can help ensure that plastic items are placed in the proper bins and actually recycled.
Once the plastic containers have been prepared and sorted, they can be placed in the recycling bin for collection. In some areas, this may be a curbside pickup service, while others may require the use of a recycling facility. After collection, the recyclables are typically taken to a Materials Recovery Facility (MRF), where they are sorted and separated by hand or machine into different types of materials. It is worth noting that not all plastic containers are recyclable, and some may need to be disposed of in the general waste.
At the MRF, the sorted plastics are sent to (re)manufacturers as raw materials to be made into new products. Recycled plastic bottles, for example, can be turned into t-shirts, sweaters, fleece jackets, insulation for jackets and sleeping bags, carpeting, or new bottles. However, it is important to be aware that the recycling process for plastics is not always successful or efficient. According to Greenpeace, despite the efforts of consumers to recycle, only about 5% to 6% of U.S. plastic waste was recycled in 2021, with similar rates reported by the United Nations Environment Programme on a global scale.
Despite the challenges and low recycling rates, the act of recycling plastic containers can have a positive impact on the environment. It is important to be mindful of the types of plastics and the recycling processes available in your area to ensure that your efforts are effective.
