Kampanjen mot spridning av avloppsslam är inte bara en udda företeelse i Sverige. Opinionen ökar starkt. Här ett exempel från San Fransisco i USA:

Take Action Against Toxic Sludge

Tell San Francisco City Officials to Stop Endangering Public Health and Degrading the Word "Organic" by Distributing Toxic Sewage Sludge Under the Guise of "Organic Compost"

The city of San Francisco, along with other municipalities across the U.S., are trying to trick Bay Area gardeners and farmers into spreading toxic sewage sludge on their fields and gardens. We need to stop San Francisco from promoting and distributing toxic sludge, and then we need to stop your city from doing the same thing.
The San Francisco Public Utilities Commission pays Synagro, the corporate giant of the toxic sludge industry, to take its toxic sewage sludge, mix it with the waste of a half-dozen other California counties, and then claim that it's been magically transformed into "high-quality, nutrient-rich, organic biosolids compost." But of course sewage sludge is hazardous waste, not "organic fertilizer." Sewage sludge is banned in organic agriculture and it should be banned for all land applications, period.
Municipal sludge is the toxic residue that is left over after household, industrial, hospital, and storm-water sewage has passed through a waste-water treatment plant.
Municipal sludge routinely contains hundreds of dangerous pathogens, toxic heavy metals, flame retardants, endocrine disruptors, carcinogens, pharmaceutical drugs and other hazardous chemicals.
Cities such as San Francisco and the toxic sewage sludge industry shouldn't be allowed to continue to lie to us and poison us!
San Francisco and other cities' toxic sewage sludge giveaways must stop.
Over 4,000 OCA activists have emailed San Francisco Mayor Gavin Newsom in protest and hundreds have called, but his office still claims not to understand the problem.
Please help us get their attention by sending a free fax to Mayor Newsom!
