The Board of Supervisors in San Francisco has been talkin’ trash—compost, that is. The Board passed new rules for recycling and composting, and future fines are planned for throwing out scraps, making it the toughest recycling law in the US. San Franciscans may want to think twice about putting food into their regular trash containers, as doing so may someday cost them a fine of $100. The rules designate a new green container for compost in addition to the familiar blue container for recyclables and black container for garbage. The fines for misplacing food scraps will be introduced in 2011, thus allowing residents ample time to familiarize themselves with the new system. It’s a good wakeup call for the rest of the nation to give leftovers the once-over before tossing them.
