What You'll Learn
Identifying BPA-free plastics
Bisphenol A (BPA) is a chemical used in the manufacturing of polycarbonate plastics. It is also used in epoxy resins that coat the insides of canned goods and water supply pipes. BPA leaches into food and water supplies very easily. According to the Mayo Clinic, BPA exposure can affect the brain, the prostate gland of fetuses, infants, and children, and it might increase blood pressure.
- Look for a recycling symbol or code, usually found on the bottom of the product. Recycling codes 1 (PET or polyethylene terephthalate), 2 (HDPE or high-density polyethylene), 4 (LDPE or low-density polyethylene), 5 (PP or polypropylene), and 6 (PS or polystyrene) are typically BPA-free. However, avoid plastics marked with recycle codes 3 or 7, unless there is a leaf symbol next to the number, indicating that the plastic is BPA-free. Polycarbonate plastics will have a number 7 on them, but they are not the only plastic labelled with a 7, so further investigation is needed.
- Check for labels indicating that the container is "BPA-free", "handwash only" or "microwave-safe". If a container has a "handwash only" label, it is probably made of acrylic and is okay to keep. On the other hand, if a container is labelled as "microwave-safe" or "unbreakable", it likely contains BPA and should be discarded.
- Opaque plastics are usually BPA-free, so if you can't see through the plastic, it is likely safe.
- New plastics are typically BPA-free and labelled as such.
- Polypropylene is a type of plastic that is generally considered safe for humans and is BPA-free. It is FDA-approved for food contact and has a high heat tolerance, so it is often used in food containers and packaging for products that can be heated in a microwave.
- Avoid using plastic containers for hot food or drinks, as heat increases the chances that chemicals will seep out of the container and into your food. Instead, opt for glass or metal containers.

Risks of non-BPA-free plastics
Bisphenol A, or BPA, is a common building block in resins and some types of plastic. It is what is known as an endocrine-disrupting compound. In the body, these chemicals can act like hormones or disrupt normal hormone functions. Exposure to BPA has been linked to a range of health issues, including reproductive, developmental, and metabolic effects.
Due to the health concerns associated with BPA, manufacturers have developed a range of alternative products marketed as "BPA-free". However, research suggests that these alternatives may also pose health risks. For example, some studies indicate that bisphenol S (BPS), a common replacement for BPA, may be an endocrine disrupter and could potentially be worse than BPA. Other similar replacements include BPF and BPZ, which may also have negative health effects.
One issue with BPA-free plastics is the lack of robust studies on their potential health risks. Many of the compounds used in these plastics have not been thoroughly tested, and it is possible that they could leach chemicals or shed microplastics. Additionally, some BPA-free products may still contain trace amounts of BPA due to contamination during the manufacturing process.
It is important to note that the risks associated with non-BPA-free plastics may depend on various factors, including the type of plastic, the presence of other chemicals, and the duration and level of exposure. While there are some safer alternatives to BPA-containing plastics, such as polypropylene and glass, it is always a good idea to be cautious and stay informed about the potential risks of any materials that come into contact with food and drinks.

Polypropylene as a safer alternative
Polypropylene is a safer alternative to other plastics for several reasons. Firstly, it is free of Bisphenol A (BPA), a chemical used in the manufacturing of polycarbonate plastics that can leach into food and water supplies and potentially cause health issues. The absence of BPA in polypropylene makes it a safer option for food and drink containers, as there are concerns that exposure to BPA may lead to problems with brain development, immune function, learning abilities, and reproductive disorders.
Secondly, polypropylene is considered one of the safest commercial plastics on the market and is generally recognised as safe for human use. It is FDA-approved for food contact and is often used in food containers for products like yogurt, cream cheese, and butter. Polypropylene is also approved by the EPA as a safe plastic. Additionally, it has a high heat tolerance, making it suitable for packaging food that can be heated in a microwave. Its heat resistance also contributes to its safety profile, as heat can increase the leaching of chemicals from plastic into food.
Thirdly, polypropylene is not known to cause cancer in humans. Several safety organisations, including the International Agency for Research on Cancer (IARC) and the Occupational Safety and Health Administration (OSHA), have concluded that polypropylene is not carcinogenic. This further supports its status as a safer alternative to other plastics.
However, it is important to note that polypropylene is not without its potential risks. While it is considered safer than other plastics, it is not risk-free. Some studies have suggested that polypropylene may affect androgen hormones and trigger a toxic or stress response in cells. Additionally, polypropylene can leach plastic additives, and its use should be limited as new studies indicate that polypropylene microplastics may be harmful to health and the environment. Therefore, while polypropylene is a safer alternative to other plastics, it should still be used in moderation and with caution.

The history of BPA plastics
Bisphenol A (BPA) is a chemical compound primarily used in the manufacturing of various plastics. It is a colourless solid that is soluble in most organic solvents but has poor solubility in water. While BPA was first synthesised by chemists in 1891, it wasn't until the 1950s that it became relevant. This was when the thriving plastic industry underwent a technological revolution, with the introduction of new materials, design techniques, and processes such as injection moulding.
In 1953, Dr Hermann Schnell of Bayer invented polycarbonate (PC) resin, a gooey substance that hardened in a beaker. Around the same time, chemist Dr Daniel Fox of GE made the same discovery while working on developing a new wire insulation material. Both were impressed by the toughness of the material, which could undergo large plastic deformations without cracking or breaking. While both companies applied for US patents in 1955, they agreed that the patent holder would grant a license for an appropriate royalty. This allowed both companies to concentrate on further development.
Polycarbonate was initially used for electrical and electronic applications, such as distributor and fuse boxes, displays and plug connections, and for glazing in greenhouses and public buildings. Its characteristics became popular for other applications, including plastic bottles and linings for metal-based food and beverage cans. In the 1960s, the FDA approved the use of PC for food packaging under its food additive regulations. Since then, polycarbonate plastics have been used to make products like reusable water bottles, food storage containers, drinking glasses, pitchers, baby bottles, and sippy cups.
However, there have been growing concerns about the safety of BPA. In the early 1990s, Dr David Feldman conducted studies on estrogen activity and discovered what looked like an estrogenic molecule while growing yeast in plastic flasks. Feldman and his team then identified the molecule as BPA, which was leaching from the plastic. They found it was not present when they performed the same experiment in glass flasks. As a result, several jurisdictions have taken steps to reduce exposure to BPA, particularly by banning it from baby bottles, sippy cups, and baby formula containers. There has also been a push to introduce BPA-free plastics, which are manufactured using alternative bisphenols such as bisphenol S and bisphenol F.

How to tell if plastic is BPA-free
It is important to identify if a plastic product contains Bisphenol A (BPA) or not, as exposure to BPA can negatively impact your health.
Firstly, you can assume that any opaque plastics are BPA-free. So, if you can't see through the plastic, that’s the first step in identifying a BPA-free product.
Secondly, check if the plastic is soft and pliable. Plastics containing BPA are usually translucent and hard, such as in water or baby bottles.
Thirdly, check the recycling number at the bottom of the container. Polycarbonate plastics will have a number 7 on them, but they’re not the only plastic that gets labelled with a 7, so you’ll need to do some further investigating. Look to see if the container is labelled as unbreakable or microwave-safe. If it is, that’s a good indicator that it contains BPA. If you see a label indicating that the container is handwash only, it’s probably made of acrylic and therefore OK to keep. Recycling codes 1, 2, 4, 5 and 6 are generally considered safe and free of BPA.
Finally, check how old the plastic product is. If a product has been in use since the late 1950s, there is a possibility that it contains BPA and is less likely to have an identifying label.
It is also worth noting that polypropylene is a type of plastic that is BPA-free.
