Cornucopia’s Take: The disposal of society’s wastes is frequently met with an “out of sight out of mind” approach. Everything that goes down the drains in our homes, industries, and institutions ends up in waterways and as sewage sludge from water treatment plants. According to the EPA more than 50 percent of the seven million dry tons of sewage sludge produced nationally ends up on farmland. Using sewage sludge on organic farms is prohibited by federal law.
While recycling the nutrients in human waste is key to ultimate sustainability, there is concern over chemical uptake into the food chain from potential unregulated contaminants, including pharmaceuticals, industrial chemicals, and heavy metals. Some European countries have created closed loops for industrial wastes and are composting residential sewage in response to sewage contamination.
