The great recycler

San Francisco mayor Gavin Newsom announced this week that the city of San Francisco leads the nation with a 72 percent recycling rate. And a new mandatory ordinace to recycle compostable materials began this week, following the mayor's successful construction debris recycling ordinance, which has accounted for the lowest tonnage sent to landfills in over 30 years.
