You know those SIGG aluminum water bottles that eco-geeks carry around with them as a protest against plastic bottles? Well apparently, SIGG bottles manufactured before August of last year contain BPA in their epoxy liner – according to a press statement made recently by Steve Wasik, CEO of Sigg. (Bisphenol A, as many of you know, has been shown to be an estrogen-like endocrine disruptor, and most companies have been removing it from food and drinking containers in the past few years). We feel strongly about the bottled water issue and have done our fair share of Sigg bottle promotion on Inhabitat over the years, so we were appalled to hear this news today.
