Interesting interview on CBC, sort of.
http://www.cbc.ca/mrl3/8752/news/features/bisphenol-faq-071121.wmv
She says she's 'not a scientist but', yet she goes on to give advice and CBC calls that reporting. Anyhow, raises some issues, but I am still confused. At least I learned something about those numbers on the bottom. Resin Identification Codes. They are primarily for the recyclers, not for us. But isn't it only the #7's that contain some Biphenol A? I think that's what she said. So why did she spend most of her time warning against using a water bottle more than once?

http://en.wikipedia.org/wiki/Resin_identification_code
1. PETE or PET Polyethylene terephthalate Polyester fibres, thermoformed sheet, strapping, soft drink bottles.
2. HDPE High density polyethylene Bottles, grocery bags, recycling bins, agricultural pipe, base cups, car stops, playground equipment, and plastic lumber.
7. OTHER Other plastics, including acrylic, polycarbonate, polylactic acid , nylon and fiberglass.

So here is what I still don't know:

Which is safer for carrying water and drinking cold drinks when backpacking?
1. PET water bottle, re-used a few times before recycling.
2. HDPE Nalgene Bottle, re-used many times.
7. Polycarbonate Nalgene Bottle, re-used many times.

Which is safer for pouring hot water into for making tea?
1. Re-used Gatoraid or Poweraid type bottle.
2. HDPE Nalgene Bottle, re-used many times.
7. Polycarbonate Nalgene Bottle, re-used a few times before recycling.

That interview really didn't answer this. In fact I think it provided as much misinformation as information, because its intention seemed to be influence consumers, not to educate them. They want us to buy water, and recycle the container, but not re-use it, not even once. Why not? What does that have to do with Biphenol A? Yet they still sell Nalgene bottles. WTF?


I am sticking with the #1 options until I learn more.
