San Francisco cafes are banishing disposable coffee cups

 A new cafe culture is brewing in the San Francisco area, where a growing number of coffee houses are banishing paper to-go cups and replacing them with everything from glass jars to rental mugs and BYO cup policies.

 What started as a small trend among neighborhood cafes to reduce waste is gaining support from some big names in the city’s food and coffee world.

Celebrated chef Dominique Crenn, owner of the three-star Michelin restaurant Atelier Crenn, is opening a San Francisco cafe next year that will have no to-go bags or disposable coffee cups and will use no plastic, The Associated Press (AP) reported.

Customers who plan to sip and go at Boutique Crenn will be encouraged to bring their own coffee cups, says spokeswoman Kate Bittman.

 On a bigger scale, the Blue Bottle coffeehouse chain, which goes through about 15,000 to-go cups a month at its 70 US locations, says it wants to “show our guests and the world that we can eliminate disposable cups.”

 Blue Bottle is starting small with plans to stop using paper cups at two of its San Francisco area branches in 2020, as part of a pledge to go “zero waste” by the end of next year.

 Coffee to-go customers will have to bring their own mug or pay a deposit for a reusable cup, which they can keep or return for a refund. The deposit fee will likely be between $3 and $5, the company said.
