Loop, loaded with nutrients and organic matter, makes the earth a better place. Organic matter is the best thing to add to soil because it holds nutrients for future use by microorganisms and plants. It also improves soil structure and acts like a sponge to help absorb and retain moisture. Because of this, Loop reduces stormwater runoff, erosion and sediment buildup in our waterways.
Loop enriches soil with essential nutrients that are slowly released as plants need them. These nutrients include nitrogen, phosphorus and potassium as well as micro-nutrients such as calcium, magnesium, sulfur, copper, iron, selenium, and zinc, all of which are vital for plant growth. Loop’s nutrients and organic matter feed the plants in a healthy, natural way, helping them grow bigger and better.
Loop achieves its dark earthy hue because it is loaded with carbon. University scientists have studied sites where Loop has been used and found it stores carbon in the soil and reduces greenhouse gas emissions into the atmosphere. By using 100% of Loop as a soil amendment over 42,000 tons of CO2 equivalents are offset each year. That’s like taking over 8,000 cars off the road!
Adding Loop to soil offsets greenhouse gas emissions in 3 major ways.
King County processes 175 million gallons of raw wastewater every day. This means that at the end of the year, about 120,000 wet tons of Loop have been extracted from wastewater and processed for use. Using a favorite metric, that’s enough Loop to cover a football field to a height of 67 feet. With 1.4 million citizens contributing to the wastewater, there doesn’t seem to be an end of Loop in sight. One of the best things about using Loop as a soil amendment is that all those tons of beneficial nutrients and good carbon are put to good use, not wasted in a landfill or incinerated.
Producing synthetic fertilizers uses massive amounts of energy and contributes to increased greenhouses gasses in the atmosphere; just imagine the energy associated with mining mineral phosphates and pelletizing nitrogen gas. By using a recycled product such as Loop, we are avoiding the greenhouse gas emissions associated with synthetic fertilizers.
In contrast, Loop production creates energy via the capture of methane gas emitted by microbes as they feast on raw wastewater solids inside anaerobic digester tanks at the wastewater treatment facilities. Some of this gas is used to power engines at the treatment plants while the rest of it is sold to local power utilities for distribution to their customers.
