JOINT COMPOSTING OF ANIMAL MANURE AND WWTP RESIDUALS
Abstract:LBFH, Inc. has conducted an investigation to determine the potential feasibility for joint processing of the Indiantown Company Wastewater Treatment Plant sludge and Tampa Farms chicken waste.
Tampa Farms operates egg production facilities in Indiantown and Okeechobee, Florida. Both facilities require the management and disposal of accumulated chicken manure. The Indiantown facility has implemented a pilot project, which involves windrow composting of the Indiantown chicken manure waste. The process currently involves the mixing of ground/mulched yard waste with the chicken manure to ultimately produce a stable and useful end product.
The Indiantown Company Wastewater Treatment Plant (WWTP) is a 1.0-million gallon per day (MGD) contact stabilization facility. The plant serves the unincorporated Martin County community of Indiantown, Florida. After digestion, the stabilized sludge has historically been hauled to land application sites. Due to constraints from the Okeechobee Drainage Basin, the Indiantown Company will now haul to Indian River County's Class A Facility; however, other disposal options are being explored.
The investigation involved discussions with the Tampa Farms pilot composting project operations manager, Florida Department of Environmental Protection (FDEP) regulatory officials, and regulatory and literature reviews regarding applicable composting systems. Site visits to the Tampa Farms pilot composting project and the land areas available for potential future joint composting were conducted.
It has been determined that a co-composting facility involving Tampa Farms chicken manure and the Indiantown Company sludge is indeed potentially viable. Based upon the information obtained, a potential conceptual design of a windrow co-composting system for joint processing of the wastes has been developed. While the exact requirements for the permitting, design, construction and operation of such a facility must yet be determined by the applicable regulatory authorities, such authorities view the potential joint composting facility quite favorably.
