What is the best way to communicate about biosolids? This is a question we all ask ourselves, all the time. It is a question we will have to keep asking ourselves. The landscape around us changes and so does the world of communications. 

The City of Missoula collects and treats wastewater generated in the Missoula area. They produce about 2,000 dry metric tons of biosolids each year, which are sent via a conveyer belt to their neighboring compost facility, formerly EKO Compost. In 2012, the City of Missoula bought the land under EKO Compost for $1.5 million and in 2016, the City bought EKO Compost itself.
