King County, WA (11/13/14) -- This article provides examples of how land applying biosolids is a way to reduce carbon emissions. When biosolids are applied to land some of the carbon remains in the soil, through a process called carbon sequestration. In addition biosolids helps improve plant health and increasing greenery helps remove carbon from the atmosphere. 100 percent of King County’s Loop biosolids are recycled as fertilizer and soil conditioner each year. Between biosolids recycling and the production of renewable energy, the utility estimates its carbon offset is equivalent to 42,000 tons of CO2 each year.
