Five misconceptions about single-use plastics that might surprise you.
Plastic bags and other single-use plastics aren't good for the environment, but they are only one component to sustainability.Single-use plastics, like plastic grocery bags, are often the poster child for waste. Despite this notoriety, these materials aren’t necessarily as wasteful as many consumers may think. According to a new study, there are a number of similar misconceptions about how certain consumer behaviors, like using plastic bags, actually affect the environment.
To do the study, Miller used a strategy called life cycle assessment, which evaluates the environmental impacts of each stage of a product’s life from creation to disposal in a variety of categories.
Others are less intuitive. For instance, Miller found that the environmental impact of packaging only comprised about 10 percent of a product’s overall environmental impact, measured across a variety of categories. That held true even for food, which is a material many of us think of as transient. “This study was really trying to put [that finding] into a bit better context,” she says. “It’s not that we don’t want to worry about single-use plastics, but it really is not seeing the forest for the trees.”
