Mother Nature Network | One group says the city’s free compost is processed sewage sludge — the product of anything flushed, poured or dumped into the wastewater system. San Francisco wears its environmental consciousness like a green badge of honor. Residents separate and recycle their food scraps. Streets close to cars so people can walk and bike them. A city department even gives away “high-quality, nutrient-rich, organic bio-solids compost” to any and all takers.
AlterNet.org | When San Francisco, one of the greenest cities in America, offered its residents free compost, many were excited to take it. Few of the gardeners who lined up to receive the free compost at events like last September’s Big Blue Bucket Eco-Fair suspected that the 20 tons of free bags labeled “organic biosolids compost” actually contained sewage sludge from nine California counties. On Thursday, March 4, angry San Franciscans returned the toxic sludge to the city, dumping it at Mayor Gavin Newsom’s office in protest.
