Today’s habit is, I think, quite specific to where you live because, as far as I know, many places recycle platic bottle caps together with the rest of the bottle. But here plastic recycling is not as advanced as one would want. However, bottle caps are collected separately for charity actions whose profits are used to buy wheelchairs for children or for other causes.
We have stopped throwing bottle caps (and other caps) away and instead collect them in a special container we keep in the kitchen. We used to have a plastic bag for it but it looked bad and the container doesn’t draw any attention at all. Once it’s full we take the caps to a collection place (I know of three nearby: in the store, in the kindergarten and in the medical center, each collecting the caps for a different cause). And that’s it.
Why do it:
Since they are collecting the caps and even giving someone money for it, at least it’s pretty certain they do get recycled and don’t end up in the dump. Also, if at no cost and no effort at all we can help someone, then there’s really no reason not to do it.

Obviously it costs nothing.

This may be the simplest thing we do.
✤ Well, you have to take the caps and bring them to a collection point. That barely counts.
✤ If we empty a bottle away from the house we need to remember to take the cap with us instead of throwing it away but as they weigh nothing it’s really not a problem.
