Glass vs Plastic Bottles
Wednesday, May 7th, 2008My dad tells stories of how his family would put out two empty glass quart bottles on their back porch and the milkman would come to deliver two new quarts of milk and take the empties.
Those days were well before my time, but I do remember when Gatorade was sold in glass bottles instead of plastic.
The move to plastic bottles was due in large part to the fact that plastic bottles are significantly lighter than glass bottles. With less container weight than glass, plastic bottles have lower associated shipping costs versus glass.
However, concerns are now emerging with the safety of plastic bottles. Lisa Farino of MSN Health & Fitness reports:
Responding to growing consumer concern, sports-bottle maker Nalgene announced today that it will be phasing out the use of the chemical bisphenol-A (BPA) in its plastic containers over the coming months.
BPA is a common building block of hard polycarbonate plastics (such as sports bottles, baby bottles, and eye glasses) and is also found in the resin lining of metal food and beverage cans.
Because BPA mimics estrogen, there has been increasing concern that exposure, especially by fetuses, newborns, and infants, may cause long-term health impacts such as early puberty in girls, reproductive problems, and cancers later in life.
The article makes me wonder, in addition to bisphenol-A, what other potentially harmful chemicals are in hi-tech plastic bottles? In a health conscious society, will old-fashioned glass bottles make a comeback?
