Presentation Title: Composting in Key West – A Successful Demonstration Program
Presentation Description: The City of Key West currently generates approximately 6000 tons of dewatered wastewater solids which are hauled to landfill in Okeechobee over 250 miles away. In addition, the City generates more than 4500 tons of yard waste materials that are hauled to a composting sites over 200 miles away. The cost of hauling and disposing of these materials is significant. The City desires to develop a more sustainable approach to manage these waste materials. Because these two materials are potentially mutually beneficial for composting to produce a valuable soil amendment, Jacobs worked with the City of Key West to develop a biosolids composting pilot project on the Key West Wastewater Treatment Plant (WWTP) site using the aerated static pile (ASP) composting method. Jacobs submitted to the Florida Department of Environmental Protection (FDEP) a Pilot demonstration study request on November 4, 2021 which was subsequently approved by the Florida DEP as part of a Permit Exemption letter dated December 6, 2021. The demonstration project was performed on the City of Key West WWTP site on a paved portion of the site beginning on February 8, 2022 and completed on March 31, 2022. The demonstration project was supervised and operated by trained operations personnel. This presentation will provide results of the pilot study, analytical results of the Class AA biosolids compost product, and subsequent compost marketing work that was performed to validate the viability of developing a full-scale composting program in Key West.
