Last August, I posted an article  Eliminate Chronic Waste  which described my observations at a New York coffee shop.  This location continuously brewed coffee each 20 minutes.  They dumped the previous batch down the drain.
Bloomberg.com reports Starbucks has decided to reduce waste through a policy shift on afternoon  decaf brewing procedures.  After noon each day, decaf coffee will be available on request.  Previously, the decaf coffee was continuously brewed.
