What You'll Learn
Plastic #5 is polypropylene
Polypropylene is used in production because it is lightweight, strong, versatile, and can withstand high temperatures. It also offers good protection from moisture or chemicals. In other words, you can bend it and twist it, and it will keep its shape. It 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. It is also used in bottle caps, plant pots, and even some car parts.
Despite being one of the most common plastics globally, polypropylene is also one of the least recycled plastics. It is reported that less than 1% of PP is recycled. When sent to landfills, polypropylene takes 20-30 years to decompose and may leach chemicals into the environment.
Both rigid and flexible forms of polypropylene can be recycled, but the steps for recycling are different. Many curbside recycling programs accept rigid plastic products like plastic bottles or tubs. However, most will not accept flexible PP like bags or soft packaging. It is important to check local rules and guidelines, as the recycling symbol on the bottom of a plastic product does not necessarily indicate that the item can be recycled in your community.

Plastic #5 is hard and heat-resistant
Plastic #5, also known as polypropylene (PP), is a type of plastic that is hard and heat-resistant. It has a high melting point of 340°F (171°C), making it a good choice for applications that require heat resistance. This type of plastic is often used in the manufacturing of prescription medicine bottles, yogurt cups, hummus tubs, single-use cutlery, and some packaging for personal care products like deodorant, lotion, or shampoo.
Due to its heat-resistant properties, plastic #5 can be challenging to recycle. However, there are some recycling programs that accept this type of plastic, such as TerraCycle and the All-in-One Zero Waste Box. It is important to check with local solid waste districts to find out specific regional options for recycling plastic #5.
The heat resistance of plastic #5 is due to its molecular structure. The addition of rigid aromatic rings to the resin instead of aliphatic groups fortifies the backbone of the molecular chain, making it more difficult to break. This gives plastic #5 its high heat resistance and chemical resistance.
There are other heat-resistant plastics available, such as ULTEM® (polyetherimide), PEEK (polyether ether ketone), and PBI (polybenzimidazole). These plastics are used in various industries, including automotive, aerospace, and semiconductor, where they can replace metal in many applications due to their high-performance capabilities.

Plastic #5 is used in prescription bottles
Plastic #5, also known as polypropylene, is a type of plastic that is hard, heat-resistant, and recyclable. It is often used in the production of prescription medicine bottles due to its durability and ability to withstand high temperatures. This type of plastic helps ensure that medications remain safe and effective during transport and storage.
While Plastic #5 is recyclable, recycling it can be challenging. The small size of prescription bottles can make them difficult to process in many recycling systems. Additionally, the recycling symbol on a plastic product does not always indicate that it can be recycled in your community.
To recycle Plastic #5 prescription bottles, you can explore various options. Some curbside recycling programs and recycling centers, like those in Sandy, Utah, and Oklahoma City, accept #5 plastic. Local pharmacies and pill bottle donation programs, such as Gimme 5, also offer recycling or reuse options for empty prescription bottles.
If you are unable to find a recycling program that accepts #5 plastic, you can consider reusing or upcycling the bottles for storage or crafts. Alternatively, organizations like Mathew 25: Ministries accept clean, empty pill bottles for reuse or recycling, especially in countries where such supplies are limited.
It is important to note that plastic prescription bottles have come under scrutiny due to potential health and environmental concerns. Some studies suggest that chemicals from the plastic can leach into the medicine, potentially affecting its effectiveness or causing harm. Proper cleaning and storage of prescription bottles are crucial to mitigate these risks.

Plastic #5 recycling is challenging in the US
Plastic recycling is challenging, and this is especially true for Number 5 plastics. The chasing arrows symbol on plastic products does not necessarily mean that an item can be recycled in your community. The number 5 plastic recycling symbol indicates polypropylene, often shortened to PP. This type of plastic is hard and heat resistant, and it is commonly used in prescription medicine bottles, yoghurt cups, hummus tubs, single-use cutlery, and packaging for personal care products like deodorant, lotion, or shampoo.
There are a few solutions to help keep Number 5 plastics out of landfills. For example, some curbside and drop-off programs are reintroducing Number 5 rigid plastic recycling, but films and bags remain a problem. You can check your local solid waste district to find out about local recycling options. There are also a few mail-in options for recycling polypropylene, such as the international humanitarian aid and disaster relief organization, Mathew 25: Ministries, which accepts clean, empty pill bottles. Another company, TerraCycle, has programs that allow you to recycle almost any type of waste.
It is important to understand the seven plastic recycling symbols, as they represent different types of plastics and have distinct recycling instructions. For example, PET or PETE (polyethylene terephthalate) is the most common plastic for single-use bottled beverages because it is inexpensive, lightweight, and easy to recycle. However, its recycling rates remain relatively low (around 20%), even though it is in high demand by manufacturers. Another example is HDPE (high-density polyethylene), which is a versatile plastic with many uses, especially in packaging. It carries a low risk of leaching and can be readily recycled into many types of goods.
To make recycling easier, you can swap out plastic products for reusable options, such as glass food storage containers and metal straws. However, it is important to note that recycling is still the best step when you cannot reuse or avoid items to prevent them from ending up in landfills or harming marine life.
