In 1994, the City of Denton, TX developed an innovative biosolids recycling program that produces compost, soil blend, and a variety of mulches. In addition to the use of biosolids from the city’s wastewater treatment plant, the Beneficial Reuse operation also diverts yard waste and clean brush from the municipally-owned landfill. In FY ’20, the City of Denton received, and diverted, nearly 26 tons of yard waste and brush to be used in its compost operation. The program is known as “Dyno Dirt”.
Dr. Sally Brown doesn’t need much of an introduction. You probably already read her Biocycle column like a dedicated fan, and check out her monthly Northwest Biosolids library write ups to see what the hot new research is. Many of you have worked with her for decades, and many more of you entered the biosolids world as her graduate student. Dr.

The Soil Fertility Specialist at Oregon State, Amber Moore, and research assistant Eliza Smith, in collaboration with Dan Sullivan, Nutrient Management Specialist at OSU, and Andy Bary, Soil Scientist at WSU, are working on a project entitled, “Plant-available S release from biosolids”. The objective of the project is to investigate the amount and timing of plant-available sulfur release from biosolids produced by different technologies.
Proposed Biosolids Project in Yelm
The proposed biosolids land application project in Yelm (WA) has a coordinated anti-biosolids community group. The land owner for the proposed project recently cancelled their involvement.
Among the community group's efforts, Preserve the Commons has:
Most leaders in the biosolids arena took a circuitous path to get to where they are today. Not Andy Bary! While Andy was in graduate school studying agronomy, he worked as a research assistant at the Washington State University extension, and he found it challenging and rewarding. He says the job he has now is the only job he’s ever had in the biosolids field. Given the passion and expertise he brings to his work every day, it’s obvious he lucked out when he landed that first biosolids job.
