Plastic number 7 is a catch-all category for all plastics that don't fit into the other six categories
Plastic products are often stamped with a resin identification code, which is a number between one and seven inside a small triangle made of arrows. This system was developed in 1988 by the Plastics Industry Association and has been distributed by ASTM International since 2008. The numbers identify the types of plastic and make up the ASTM International Resin Identification Coding System, commonly referred to as RIC.
The category includes recyclable, non-recyclable, and biodegradable plastics, as well as multi-layer or mixed resin types. Some common plastics in this group are nylon, polycarbonate, melamine, and Acrylonitrile Butadiene Styrene. Polycarbonate, or PC, is particularly controversial due to its association with Bisphenol A (BPA), a highly toxic chemical linked to obesity, cancer, and endocrine problems in children and fetuses.
Some everyday items made from plastic number 7 are baby bottles, plastic CDs, eyeglasses, car parts, and exterior lighting fixtures. While it is challenging to recycle these items, they can often be reused or "upcycled" and kept out of landfills.

Plastic number 7 includes new plastics, bioplastics, and items composed of multiple types of plastics
Plastic is everywhere in our modern world. It is found in a variety of different shapes and colours, with many different uses. There are seven different types of plastic available to the general public, each with its own recycling number from 1 to 7. These numbers are part of the Resin Identification Coding System (RIC), which was developed in 1988 by the Plastics Industry Association. The system is used to identify the type of plastic resin used to create a product and to guide the public on how to recycle it.
Plastic number 7 includes any new plastics, bioplastics, and items composed of multiple types of plastics. It is essentially the \"other\" category, for any plastic that doesn't fit into the first six categories. It is also known as polycarbonate (PC) and contains the highly dangerous chemical Bisphenol A (BPA). This chemical is linked to obesity, cancer, and endocrine problems in fetuses and children. Due to the presence of BPA, products with the PC label should be avoided.
It is hard to recycle number 7 plastic, and most recycling factories do not accept it. There are no standard protocols for reusing this plastic, so it is better to opt for recycling numbers 1, 2, 4, and 5, which are considered safer. However, it is important to note that all plastic products can leach toxic chemicals when heated or damaged, so it is best to move to other materials like metal and glass where possible.

Plastic number 7 contains polycarbonate (PC), which releases the highly toxic chemical Bisphenol A (BPA)
Plastic is everywhere in the modern world, and it is almost impossible to escape it. Plastics are labelled with numbers from 1 to 7, which indicate the type of resin used and the possibility of recycling. Plastic number 7 is the final plastic category and represents all other plastics that do not fall under the first six categories. This includes new plastics, bioplastics, and items composed of multiple types of plastics.
The primary source of exposure to BPA for most people is through their diet, as BPA can leach into food from the protective internal epoxy resin coatings of canned foods and consumer products such as polycarbonate tableware, food storage containers, water bottles, and baby bottles. Exposure to BPA through air, dust, and water is also possible, but exposure through dietary sources accounts for the majority of daily human exposure.
Due to the presence of BPA, it is recommended to avoid products with the PC label and to reduce the use of canned foods. Consumers are advised to opt for glass, porcelain, or stainless steel containers, especially for hot food or liquids. Baby bottles should be BPA-free, and polycarbonate bottles should not be used for bottle-feeding infants, as they may have higher BPA exposure than adults.

Plastic number 7 products include baby bottles, plastic CDs, eyeglasses, car parts, and exterior lighting fixtures
Plastic Number 7, also known as "Other", is a catch-all category for plastics that do not fit into the first six categories. This includes polycarbonate, polyethylene terephthalate glycol (PETG), and other resins. Polycarbonate is a strong and impact-resistant plastic commonly used in eyeglasses, safety glasses, and electronic components. It is also translucent, almost like glass, while being able to withstand high impacts. It is pliable at room temperature, making it easy to work with for manufacturers. Polycarbonate is an excellent alternative to glass and has a natural UV filter, which is why it is often used in windows and eyewear. However, polycarbonate has been associated with bisphenol A (BPA), a highly toxic chemical linked to obesity, cancer, and endocrine problems in fetuses and children. Due to these health concerns, polycarbonate is less commonly used today.
Number 7 plastics also include baby bottles, plastic CDs, car parts, and exterior lighting fixtures. These products may be made from various plastics within the Number 7 category, such as polylactic acid (PLA), nylon, or melamine. Many items made from Number 7 plastics can be challenging to recycle. While some Number 7 plastics are recyclable, they often cannot be recycled through curbside recycling programs. This is because Number 7 plastics encompass a wide range of plastics, some of which are recyclable, while others are not. Therefore, it is essential to check the specific type of plastic and the local recycling facilities available.
The versatility of Number 7 plastics poses challenges for recycling and waste management due to the variety of materials involved. However, understanding the specific properties and uses of different types of Number 7 plastics is crucial for developing more sustainable practices and innovative recycling technologies. Additionally, consumers can play a role in reducing waste by reusing or repairing items made from Number 7 plastics instead of immediately disposing of them.
Overall, Plastic Number 7 is a diverse category that includes a broad range of plastics with various characteristics and applications. Its products include baby bottles, plastic CDs, eyeglasses, car parts, and exterior lighting fixtures, showcasing the wide range of uses for this versatile yet complex type of plastic.

Plastic number 7 is difficult to recycle and most recycling programs won't accept it
Plastic Number 7, also known as 'Other', is the final plastic category in the ASTM International Resin Identification Coding System (RIC). It includes plastics that do not fit into the first six categories, such as bioplastics, polycarbonate (PC), acrylic, and nylon. It also includes items composed of multiple types of plastics.
Plastic Number 7 is notoriously difficult to recycle. Most recycling programs and factories do not accept it due to the lack of standard protocols for its reuse. It is often made of multiple plastic types or other hard-to-recycle plastics that cannot be easily processed. For example, Styrofoam, which is challenging to recycle due to its tendency to break apart into smaller pieces, is considered a Number 7 plastic. Similarly, polycarbonate, which is a clear, hard plastic, is also a Number 7 plastic and is rarely accepted for recycling.
The RIC system was developed to help identify the type of plastic resin used in a product and guide consumers and recycling centers on the steps needed for proper recycling. However, the presence of a resin code does not guarantee recyclability. The number within the triangle, which corresponds to a specific type of plastic, is what determines whether an item can be recycled.
While some curbside recycling programs are starting to accept Number 7 plastics, they are still relatively rare. Consumers are advised to check their local municipality's guidelines before placing Number 7 plastics in their recycling bins. It is worth noting that just because a plastic type can be recycled does not mean it is always accepted by local recycling programs. Some plastics, like Styrofoam, are considered too hard to process by many recycling companies.
Overall, it is essential to prioritize reducing plastic consumption and choosing safer alternatives like metal and glass. When plastic use is unavoidable, opting for plastics with higher recyclability rates, such as Numbers 1, 2, 4, and 5, can help reduce the environmental impact. Reusing and upcycling plastic products can also keep them out of landfills and give them a new lease of life.
