What’s a 4R Star?

Become a “4R Star” with CVSan’s “4R Business, 4R Planet” Award Program. To recognize and reward businesses for being a company where green practices are business as usual, CVSan implemented the 4R Business, 4R Planet Award Program in 2009.  The 4R Business, 4R Planet program certifies “4R Star” businesses that complete ongoing activities in each of the 4R categories – Reduce, Reuse, Recycle, and Rot (organics).  4R Star businesses are also periodically recognized in the Castro Valley Forum, through news releases, events, and on our website, all of which is provided – at no cost – by CVSan.
