Elliot is certified through the USCC as a Compost Operations Manager and is the Organic Resources Manager for the City of St. Peters, Missouri. In the past ten years with the City of St. Peters, he has focused his sights on increasing production efficiencies by intensely researching modern equipment and implementing production improvements specific to the struggles presented by his materials and climate. Elliot has worked in all aspects of his career from hands on maintenance, facility design, operations, management and marketing, and utilized several types of processes to achieve an efficient operation and a quality product. Elliot is on Executive Board of Directors for the Composting and Organics Association of Missouri and strives to grow the compost market in Missouri through greater implementation in municipal and state projects. He has assisted facility across the United States in start-up, equipment selection, design, and process improvements.
Session Name: Biosolids Development Around the US and Guam
Session Time: Wednesday, January 29, 8:00 to 9:15 AM
Presentation Title: Degrading Polymers in Biosolids Composting
Presentation Description: In the Midwest, where rainfall is either scarce or plentiful, biosolids composting presents a plethora of inconsistencies, often accompanied by struggles in production. In a previous presentation I discussed measures of post-process amendment bulking; where the bulk density of the mass of material that had surpassed the USEPA 503 requirements in aerated static pile composting, had been altered. This process implemented the use of both ASP and turned windrow composting and required excessive handling of the material. In an attempt to reduce the amount of times the material was handled, and reduce costs associated with the dual processing, I opted to strongly monitor the characteristics of the materials; documenting bulk densities, oxygen saturation, moisture contents, pH, and Solvita results, throughout each stage of my current process, Aerated Static Pile, Turned Windrow, and Curing.
In my experience with biosolids composting, I have found that even though cured material appears to be fairly dry, or presents little moisture and a fairly light bulk density, the material still tends to cause either difficulty while screening or produce a low fines yield.
In this presentation, I will outline a strategy I developed for my facility that maximizes the efficiency of our ECS ASP system to thermally degrade polymers used in biosolids production, before they become a nuisance to screening operations. I will discuss how I utilized our ASP facility in strategically controlled regimes to reduce the adhesive-like properties of wet biosolids compost and reduce the use of alternate measures previously used to retain a consistent moisture content throughout the curing stage. The presentation will outline the relationship between when the polymers were added to the waste activated sludge and their impact on the initial mix characteristics and how altering several aspects impacted screen efficiency and site planning.
Session Time: Wednesday, January 29, 4:15 to 5:45 PM
Presentation Title: Marketing Municipal Compost: Q&A with a Panel of Practitioners
Presentation Description: Marketing your finished compost and compost-based products can provide significant income, often making the difference between net profit and loss.But for municipal governments and agencies, who are service-driven and not for-profit, even the act of selling compost can be controversial.Fear of accusations of unfair competition with the private sector is an issue.Just managing the bureaucracy can be a hurdle.Listen to 3 municipal compost managers explain how they are working to overcome these and other barriers in this interactive session.
