Plastic products are often stamped with a number, known as a resin code, which identifies the type of plastic used. The number is usually found within a small triangle made of arrows. Plastic number 3, also known as PVC, is considered unsafe and one of the least recyclable plastics. It is dangerous due to the presence of softening chemicals, which can cause hormonal issues and other health problems.

What You'll Learn
Plastic #3 is known as PVC (polyvinyl chloride)
PVC contains softening chemicals called phthalates, which are known to cause hormonal problems. It can also produce other highly toxic chemicals, such as DEHA, which have been linked to developmental issues in children, immune and endocrine system problems, and cancer.
Due to these health concerns, it is recommended to avoid using plastic #3 for food storage or cooking. It is important to check products like baby toys and inflatable items to ensure they do not contain PVC.
PVC is challenging to recycle due to the different additives used in its production. It is best to minimise the use of plastic #3 and opt for safer alternatives like glass, metal, or bamboo.

PVC is dangerous and one of the least recyclable plastics
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.
Plastic #3, also known as PVC (polyvinyl chloride), is one of the least recyclable plastics. PVC is a soft, flexible plastic, so it’s used for a huge array of household products. It is strong and elastic due to softening chemicals, phthalates, which cause problems with the hormonal system. PVC is toxic at every stage of its production and disposal. Its precursor chemical is carcinogenic, and it can release noxious compounds, especially when burned. It is also difficult to recycle due to the different additives used to make it flexible.
PVC is dangerous to human health, as it contains toxic chemicals such as DEHA, which can affect child development, the immune system, and the endocrine system. It also poses risks to the environment, as it can contaminate water and soil, threatening ecosystems and becoming part of the food chain. The mechanical grinding of PVC during recycling can release microplastics into the air, which can have unknown impacts on human health and ecosystems.
Due to the health and environmental risks associated with PVC, there have been calls to phase it out. The U.S. Plastics Pact has identified PVC as a problematic and unnecessary material and aims to eliminate it from packaging by 2025. Environmentalists and NGOs have also raised alarms about PVC for decades. Efforts are being made to find alternatives to PVC, although some of these alternatives may be more expensive.

It is strong and elastic due to softening chemicals
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. This number indicates the type of plastic the product is made of.
Plastic #3, also known as PVC (polyvinyl chloride), is considered very dangerous and is one of the least recyclable types of plastic. It is strong and elastic due to softening chemicals such as phthalates. These chemicals cause significant problems with the hormonal system. Other highly toxic chemicals like DEHA can also be produced during the lifecycle of plastic #3. These harmful chemicals affect children's development and immune and endocrine systems, and can even cause cancer.
Products made with plastic #3 include shower curtains, cleaner bottles, pipes, cooking oil bottles, window and door frames, floors, and clear food wrap. It is important to avoid using plastic #3 for cooking and storing food, especially baby toys and inflatable items. PVC plastic recycling is challenging due to the different additives used.
While plastic #3 has certain undesirable characteristics, it is essential to recognize that different types of plastic serve various purposes in our daily lives. It is strong and elastic, making it suitable for specific applications. However, due to the potential health and environmental risks associated with plastic #3, it is recommended to minimize its use whenever possible.

PVC contains toxic chemicals, including DEHA, which can cause cancer
Plastic products are often stamped with a resin code, a number between one and seven inside a small triangle made of arrows. This number corresponds to a different type of plastic. Plastic number 3, also known as PVC (polyvinyl chloride), is considered dangerous and one of the least recyclable types of plastic.
PVC is also filled with toxic additives, like plasticizers, which can make it more flexible. These plasticizers can disrupt the messaging system of the body and harm reproductive health. Toxic metals such as lead, cadmium, and organotins are used as stabilizers, and toxic flame retardants are added to suppress fires. All of these additives can leach from plastic during use, contaminating the environment and exposing people to harmful chemicals.
The production of PVC also poses significant health risks. The process of making PVC requires toxic and volatile chemicals, such as chlorine gas, and highly hazardous substances like PFAS, asbestos, or mercury. The Department of Health and Human Services published a draft toxicological profile for vinyl chloride, noting that it is used almost exclusively by the plastics industry and has contaminated groundwater and the air around manufacturing sites. Communities living near PVC production sites are at an increased risk of exposure to these toxic chemicals and have higher rates of cancer and other health issues.

Avoid using #3 plastic for cooking or storing food
Plastic products are often stamped with a resin code, which is a number between one and seven inside a small triangle made of arrows. This number indicates the type of plastic the product is made from and its recyclability.
Number 3 plastic, also known as PVC (polyvinyl chloride), is considered dangerous and one of the least recyclable types of plastic. It is strong and elastic due to softening chemicals such as phthalates, which cause problems with the hormonal system. Other highly toxic chemicals, such as DEHA, can be produced during the lifecycle of number 3 plastic. These harmful chemicals have been linked to negative health outcomes, including cancer, children's developmental issues, and problems with the immune and endocrine systems.
Number 3 plastic can be found in various household items, including shower curtains, cleaner bottles, pipes, cooking oil bottles, window and door frames, floors, and clear food wrap. Due to the potential health risks associated with this type of plastic, it is essential to avoid using it for cooking or storing food.
When heated, PVC releases toxic chemicals, so it should never be used for cooking or heating food or beverages. Instead, it is recommended to use glass, metal, or other materials for storing and cooking food to minimize potential health risks.
While recycling is important for reducing waste, not all plastics are easily recyclable. Number 3 plastic, or PVC, is particularly challenging to recycle due to the different additives used in its production. Therefore, it is advisable to minimize the use of this type of plastic as much as possible and opt for safer alternatives when it comes to food storage and preparation.
