The New York Times reports that glass bottles seem to be making a comeback, at least in part because of consumer concerns about bisphenol A (BPA), an industrial chemical used as a protective coating in some plastics that some researchers could create health concerns if it laches into the foods or beverages stored in those containers.
Government regulators have maintained to this point that BPA does not create health problems, but a lot of people are not convinced, believing that pro-chemical lobbyists may be as responsible for these findings as actual science.
The story says that glass does not have these potential problems, and that glass's comeback "is being helped in a small way by an entrepreneur who is developing a reusable glass bottle that is hard to break and will not shatter if broken."
According to the story, "No one expects glass to replace plastic anytime soon. After all, billions of plastic bottles are used every year. But in a survey of more than 4,000 consumers this year by EcoFocus Worldwide, a research and consulting group, 37 percent said they were extremely or very concerned about the health and safety of plastics used in food and water packaging, compared to 33 percent in 2010."
