Last weekend, at the annual Northwest Flower and Garden Show, a few King County volunteers handed me a free biodegradable bag of Loop. “Loop – Turn your dirt around” is a program started by King County in 2012 that produces compost loaded with organic matter and nutrients made of bio solids recycled as fertilizer and soil conditioner in agriculture and forestry. Loop provides nutrients for plants such as nitrogen, phosphorus and potassium and decreases our carbon foot footprint by storing carbon – mitigating effects of climate change. According to King County in 2012, Loop offset over 42,000 tons of CO2 equivalents, like taking 8,000 cars off the road.
As our population increases, and water becomes an increasingly precious resource, Loop will continue to provide nutrients for our soil, increase soil carbon storage, and help increase plant growth which removes CO2 from the atmosphere and deposits plant residue in the soil. King County currently generates over 175 million gallons of raw wastewater everyday and at the end of the year, 120,000 wet tons of Loop are extracted from wastewater and processed for use. Mountains to Sound Greenway trails use Loop to help promote soil and tree growth, helping to improve forest health in major urban places. Loop is aptly named because it prompts you to think how your waste can benefit the environment. By reusing our waste close to home, we are saving money and energy. It’s exciting to see King County implementing such onsite strategies to accomplish many things at once.
