I spent a really long time researching this for my office recycling program. jd is right. There is is no economically viable way of recycling alkaline batteries. The only available service is to pay big bucks to ship them to a “recycling” center on the other side of the country where they are incinerated, which seems of dubious environmental value to me. http://www.biggreenbox.com/
The only place in the region that provides that service is MOM’s Organic Market, so you can take your alkalines there if you really want to.
