No more BPA for you

It must be noted this is a voluntary step being taken by industry, specifically by the six largest makers of baby bottles. (Your new bicycle bottle, from Klean Kanteen. Made of stainless steel. From Katescaringgifts.)

BPA has become ubiquitous in the last decades, but an increasing number of academic studies link it to a variety of disorders, including heart disease, cancer and brain disorders.

So it's likely this is just the start.

It's possible to make cans without bisphenol-A, as well as water bottles used by adults. (Nalgene specified an end to its use last year)

The problem, as always, is that it's going to cost you. And not just in money. Polycarbonate, the type of plastic most likely to leach BPA, is inexpensive, durable and can deal with rigorous manufacturing processes.

One alternative is stainless steel. Polypropylene is another. It will take considerable research to recreate the properties that made BPA so good in a non-BPA form. But another word for that is opportunity.
