What You'll Learn
Number 7 plastic is hard to recycle
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. Each number corresponds to a different type of plastic. Number 7 plastic is a catch-all category for "other" plastics, and it is perhaps the most difficult type of plastic to define and recycle. Number 7 plastic is often made from multiple plastic types or other types of plastic that are hard to recycle.
Number 7 plastic includes polycarbonate, which is a clear, hard plastic that has been linked to health problems and environmental degradation due to its bisphenol A (BPA) content. BPA is a hormone disruptor and a highly toxic chemical associated with obesity, cancer, and endocrine problems in fetuses and children. Due to these concerns, many manufacturers have transitioned to BPA-free plastics. However, certain substitutes, such as BPS and BPF, may also disrupt endocrine function. It is recommended to avoid using plastic containers marked #7, especially when microwaving food or beverages.
The difficulty in recycling number 7 plastic stems from the fact that it is a mixed plastic, and there are no standard protocols for its reuse. Most recycling factories and programs do not accept it. This plastic is often used for water bottles, sports equipment, medical devices, DVDs, and computer and technological parts. It is important to properly identify and separate number 7 plastic from other types to facilitate effective recycling.
To recycle number 7 plastic, individuals should check with their local solid waste management or recycling offices to understand their specific policies and guidelines. Some curbside recycling programs may accept number 7 plastic items if they can be identified as such. Additionally, some specialized recycling companies may handle hard-to-recycle plastics, including number 7 varieties.

It includes many different plastics
The number 1 and number 7 plastics are two distinct categories in the plastic recycling codes system, which was developed by the Society of the Plastics Industry in 1988. This system helps consumers and recyclers identify and sort different types of plastic for recycling purposes.
Number 1 plastic refers to polyethylene terephthalate (PETE or PET), which is commonly used in beverage bottles, food containers, and some packaging materials. It is one of the most commonly recycled plastics and is generally considered safe for single use. However, it is important to note that not all PET or PETE plastics are created equal, and the safety of this material can depend on its specific composition and the type of products it comes into contact with.
On the other hand, number 7 plastic is a catch-all category that includes all other types of plastics that don't fall into categories 1 through 6. This category, often labeled as "Other," encompasses a wide range of different plastic materials, including polycarbonate, acrylic, polylactic acid (PLA), and biodegradable plastics, among others. These various types of plastic have different properties, melting points, and recycling requirements, which is why they are grouped together in this diverse category.
The number 7 category includes many different plastics because there are a vast number of plastic types and resins that don't fit into the first six categories. This category is quite broad and diverse, encompassing plastics with varying chemical compositions, melting points, and recycling protocols. Some of the plastics in this category, like polycarbonate, have come under scrutiny for potential health risks, especially when used for food or beverage storage. For this reason, it's important to pay attention to the specific type of plastic within the number 7 category, as they may have different safety considerations. It's worth noting that not all number 7 plastics are harmful, and many are safe and recyclable, but consumers should be aware of the specific type of plastic they are dealing with.
Overall, the number 1 and number 7 plastic categories highlight the complexity of plastic recycling and the importance of proper sorting and disposal. While number 1 plastics are widely recycled, the diverse nature of number 7 plastics requires consumers to be more vigilant in understanding the specific type of plastic they are using or disposing of. This knowledge can help ensure the safe and responsible use and recycling of these materials.

Number 7 plastic is not accepted by most curbside recycling programs
Plastic products are often stamped with a number, which is a resin identification code that tells consumers and recycling centres what type of plastic the product is made of. The numbers range from 1 to 7, with Number 7 representing all other plastic types besides the first six categories. Number 7 plastic includes a wide range of plastics with many different characteristics, such as polycarbonate, polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), acrylic, melamine, and nylon. Some common items made from Number 7 plastic include baby bottles, CDs, computer keyboards, takeaway containers, and car parts.
While some curbside recycling programs are starting to accept Number 7 plastics, most do not due to the difficulty of recycling these materials. Number 7 plastic is a complex group that includes recyclable, non-recyclable, mixed plastics, and biodegradable plastics. The wide variety of plastic types and characteristics within this category makes it challenging for recycling centres to process these materials effectively. Additionally, some Number 7 plastics, such as polycarbonate, are associated with the release of bisphenol A (BPA), a highly toxic chemical linked to obesity, cancer, and endocrine problems.
It is important to note that the presence of a recycling symbol on a plastic product does not necessarily indicate that it can be recycled. The number within the symbol is what matters, as it corresponds to the type of plastic and its recyclability. Even if a plastic item is technically recyclable, it does not mean that your local recycling program accepts it. Always check with your local municipality to confirm which plastic types can be included in your curbside recycling.
To reduce the environmental impact of plastic waste, it is recommended to choose safer types of plastic, such as Numbers 2, 4, and 5, which are generally considered safe. It is also advisable to avoid single-use plastics and opt for reusable alternatives whenever possible. Additionally, volunteering is another great way to fight plastic pollution and promote more sustainable practices.
While Number 7 plastic may not be accepted by most curbside recycling programs, there are other options for responsible disposal. Some specialist recyclers may accept these plastics, and organisations like Lastique International Corporation in the US work with individuals and businesses to recycle plastic waste that cannot be conveniently recycled through local programs. By exploring alternative recycling avenues and choosing safer types of plastic, we can collectively work towards reducing the environmental footprint of plastic waste.

Number 7 plastic is used in baby bottles, CDs, car parts, etc
Plastic products are often stamped with a number inside a triangle made of arrows, ranging from 1 to 7. This number is a resin identification code associated with the type of plastic used in the product. Number 7 plastic is a catch-all category for all types of plastic other than numbers 1 through 6. This category includes new plastics, bioplastics, and items composed of multiple types of plastics. Number 7 plastic is hard to recycle and most recycling programs and factories do not accept it. It includes polycarbonate plastics, which contain the highly toxic chemical BPA, a known endocrine disruptor.
Number 7 plastic is used in a wide range of products, including baby bottles, sippy cups, water cooler bottles, and car parts. It is also used in CDs, DVDs, and some computer and other technological parts. Polycarbonate is a valuable alternative to glass due to its translucent appearance and ability to withstand high impacts. It is also pliable at room temperature, making it easy for manufacturers to work with. However, polycarbonate is less commonly used today due to its association with BPA, which can leach into food or drink products, especially if used to heat liquids.
To avoid the potential health risks associated with number 7 plastic, it is recommended to choose safer types of plastic, such as those with recycling labels #1, #2, and #4, or to opt for non-plastic materials like metal and glass where possible. It is also important to note that all plastic products can leach toxic chemicals when heated or damaged, so caution should be exercised when using any type of plastic.
While it is difficult to completely avoid plastic in modern society, individuals can make more informed choices by understanding the different types of plastics and their potential health and environmental impacts. This includes reusing and recycling plastic products whenever possible and choosing plastics that are more likely to be recycled, thus reducing the amount of plastic waste in landfills.

Number 1 plastic is relatively safer but must be stored in a cool place
Plastic is everywhere, from our food and beverage containers to our household cleaning products. With so many types of plastic available to consumers, it is important to understand the potential harm of the various elements that make up these different plastics.
The numbers 1 to 7 found inside the recycling symbol on plastic products are resin identification codes, indicating the type of plastic the product is made of. Number 1 plastic, also known as PETE or PET, is one of the most commonly used plastics. It is found in beverage bottles, food jars and containers, salad dressing and oil bottles, mouthwash bottles, and even household cleaning product containers.
While Number 1 plastic is relatively safer than some other plastics, it is important to remember that all plastic products can leach toxic chemicals when heated or damaged. Number 1 plastic, in particular, should be kept out of the heat. When heated, it can cause carcinogens, such as the flame retardant antimony trioxide, to leach into liquids. Additionally, the porous nature of its surface allows bacteria and flavour to accumulate, so it is recommended to avoid reusing these containers. Therefore, it is best to store Number 1 plastic products in a cool environment and avoid reusing them.
Compared to other plastics, Number 1 plastic is widely recycled and accepted in most curbside recycling programs. However, it is always good to check with local guidelines, as accepted materials in recycling programs can vary from city to city.
