Plastic recycling is a complex and challenging process, and it's essential to understand the different types of plastics and their recyclability. Number 5 plastics, also known as polypropylene or PP, are a particular type of plastic resin that is hard and heat-resistant. While the recycling symbol on plastic products provides information about the material, it doesn't guarantee acceptance by local recycling programs. Number 5 plastics are used in various products, including medicine bottles, yogurt cups, and single-use cutlery, but their recyclability depends on local regulations and infrastructure. Understanding the seven plastic recycling codes and local recycling guidelines is crucial for responsible waste management and ensuring that number 5 plastics are recycled properly.

What You'll Learn
Number 5 plastics are hard and heat-resistant
Number 5 plastics, also known as polypropylene (PP), are hard and heat-resistant. They are commonly used in products such as yoghurt cups, medicine and ketchup bottles, kitchenware, and "microwave-safe" plastic containers. Due to their heat-resistant properties, they are considered safe for microwave use and will not warp when exposed to heat. However, it is recommended to avoid microwaving food in PP containers, as it may not be healthy for consumption. Instead, it is advised to use glass containers for microwaving.
Polypropylene is widely accepted by most curbside recycling programs. When recycling Number 5 plastics, it is important to separate the silicone parts, such as nipples and valves, from the plastic components. As long as the smaller parts are attached to the bottles, making them larger than 3 inches, the entire assembly can be recycled.
The heat resistance of plastics, including Number 5 polypropylene, can vary depending on their molecular structure. Thermoplastics, for example, gain their heat resistance from the presence of rigid aromatic rings in their resin, which fortify the backbone of the molecular chain. This modification enhances their chemical and heat resistance compared to thermosets.
Additionally, some plastics possess exceptional heat resistance, such as PTFE, commonly known as Teflon. PTFE has a very high melting point of approximately 327°C and can operate within a wide temperature range, from -200°C to 260°C. This makes it suitable for applications requiring high temperatures, such as non-stick cookware, pipe protection, and electrical component insulation.
Another notable heat-resistant plastic is PEEK (polyether ether ketone), a high-performance engineering thermoplastic. PEEK exhibits remarkable resistance to heat, chemicals, wear, fatigue, and creep. It can withstand temperatures up to 310°C for short periods and has a melting point exceeding 371°C. PEEK's durability and adaptability make it a preferred choice over metal in various industries, including medicine, automotive, and aerospace.

They are often used in medicine bottles, yogurt cups, and hummus tubs
Polypropylene plastic, often marked with a #5, is commonly used in medicine bottles, yogurt cups, and hummus tubs. Many recycling programs do accept #5 plastic, but it is always worth checking the rules of your local program. For example, New York City accepts #5 plastic, and Greensboro, North Carolina, accepts #5 yogurt containers. However, some programs do not accept small items, such as yogurt cups, as they are difficult to separate during the recycling process.
If your local program doesn't accept #5 plastic, there are other options for recycling these containers. You can use an online map, such as Recycle More Plastic's, to find a nearby collection program that specifically accepts polypropylene plastic. Additionally, some stores, like Whole Foods, have collection bins as part of their recycling programs.
It is important to note that reducing plastic consumption is more environmentally friendly than recycling. For example, instead of buying hummus in plastic tubs, you could make your own hummus and store it in a reusable container. This reduces the amount of plastic waste generated in the first place, which is a more sustainable approach.
When it comes to recycling, it is easy to make mistakes, such as throwing something in the wrong bin. Therefore, it is important to be mindful and take the time to understand the recycling guidelines in your area.

Curbside recycling programs may not accept them
Plastic recycling is becoming increasingly challenging, especially for number 5 plastics. Number 5 plastics are made from polypropylene, commonly known as PP. PP is a particularly hard and heat-resistant plastic that is often used in prescription medicine bottles, yoghurt cups, hummus tubs, single-use cutlery, and some packaging for personal care products like deodorant, lotion, or shampoo.
Curbside recycling programs may not accept number 5 plastics. This is because the recycling symbol on the bottom of a plastic product does not necessarily indicate that the item can be recycled in your community. The number 5 with the chasing arrows symbol is a resin identification code and tells users what kind of plastic they are holding. The chasing arrows symbol does not mean that the plastic will be accepted and recycled in your community.
It is important to research and understand your town's legislation and rules for recycling so that you know what can and cannot be recycled in certain bins. You can do this by checking with your local collection centre or drop-off site to find out which plastics they can recycle. Some towns may have mail-in options for recycling polypropylene, or you can check with your local solid waste district to check for local options in your region.
Additionally, some curbside recycling programs may accept number 5 plastics, so it is always worth checking with your local program before disposing of these plastics. When number 5 plastics are recycled, they can be used to make products like battery cases and trays.
