seems like nothing we do is fool proof?

Your Nalgene bottle (and all polycarbonate #7 recyclable bottles) are made with a chemical called bispehenol A. This has been proven in labs to act like food for certain types of cancer – including breast cancer. And yes, it does leach into the liquids being contained. Bisphenol A is not only found in plastic bottles but also in the cans used to hold soda and food products. The good news is that Nalgene recently announced it will produce BPA -free bottles (although it still denies the dangers found in independant studies done on BPA).

Sigg says they can’t comment on the ingredients used in their lining because of a proprietary issue with their manufacturer. However, tests done on the linings have shown that after 2 years of frequent use there was no trace of BPA or several other chemicles in the water. Another positive aspect of Sigg bottles is that you can use any type of liquid in them – acidic fruit juices and soda included. I don’t believe the same can be said for stainless steel.

As for stainless, there are many different mixtures that can be very bad to use for food materials, how would you know where the metal was processed before it was made into the product your using?
I use stainless coffee mugs, they have a different taste than a glass mug does.
We sometimes forget the simple fact that plastic bottles suck for the reason that using them for any other substance than water remains indefinitely in the bottle, – eg. orange juice than water!

What is in your liquids your drink?, common tap water can be just as bad as a what is leaching from products.
I just like the fact I can put any liquid into the Sigg bottles and water still tastes neutral.

A stainless steel waterbottle without any buffer between the water and the metal would be the most damaging type of water bottle in concern to the consumers health.

We should not discount how green “beautiful” can be. If you buy something and keep using it for a long time you are counteracting our disposable culture which is a bigger problem for the environment than any single product or material alone. To Richie and Zeek I would ad that few things are solved in one fell swoop. SIGG isn’t perfect (I wish they used recycled instead of virgin aluminum) but they are moving in the right direction. For those of us who design for big corporations we know all too well how hard it can be to get those companies to change direction. To be fair we should applaud SIGG but also encourage them to continue to evolve and improve. I say, put your energy where your mouth is and create a design that will help spread your message and your green values.

TRYING is not good enough. If plastic coated aluminum works for you… try: ‘Tart Cherry Concentrate’ by Pure Planet . They seem to be using the same aluminum type container to house their concentrate. So the bottle would be free after the concentrate was used up.
