More people are paying attention to the recyclability of plastic containers and our collection numbers are increasing. An issue with the use of plastic containers is that they may pose health risks. There have been a lot of studies on plastics used for food and beverages and some plastics are better than others. Even the metal food cans have a plastic liner inside them. This has caused concern for health-conscious people.

Campbell has recently announced plans to eliminate the hormone-disrupting chemical bisphenol A from the linings of its soup cans. More than 93 percent of Americans show detectable levels of BPA in their urine due to food packaging with BPA and bisphenol A.

The plastic beverage containers that are made of hard, rigid plastic such as insulated water bottles for biking are typically made from the No. 4 LDPE, a low-density polyethylene plastic that is dishwasher safe, reusable and will not leach chemicals from the plastic with repeated use. This type of plastic is also used to make bread bags, frozen-food bags and squeezable bottles like ketchup and some squeezable water bottles. Many sources of information are reporting that No. 4 plastics transmit no known chemicals into the food or beverage, and they are recyclable. (Remember our recycling motto of “no plastic bags,” however.)

We read a lot about the negative research reporting on plastic containers. It’s confusing because what is not being talked about are the safe plastic products. Also, some plastic containers are safe if they are used as intended. Never, never place a plastic container in the microwave. Heat may cause chemicals to be released. Also some containers are meant for single use such as No. 1 polyethylene terephthalate. PET breaks down with use and cannot be properly cleaned.

The No. 2 HDPE — high-density polyethylene  — containers are made from petroleum and are used for sport bottles and milk jugs. They have a low risk of leaching any chemicals and are highly recyclable.

Probably the most controversial plastic use is No. 3 and No. 7. Typically we see these numbers used for non-food items like chemical storage, storage boxes, automotive parts or technology construction. They are not often used for food and beverages. Check the symbol on the container to see what number plastic you are purchasing. Everyone should be familiar with the numbers and type of plastic that is safe for foods. If the container has no triangle with Nos. 1-7 inside the arrows, it probably is made from chemicals not meant for food and beverage storage.

Glass is still a highly recommended container, especially for babies who can’t feed themselves. Stainless steel is expensive, but still a safe, reliable container for beverages, especially for storage. Glass and stainless steel are also highly recyclable.
