Abstract
This study examines the economic feasibility of 4 alternative large animal mortality composting systems that a producer-owned entity could potentially operate. The 4 systems evaluated are a vertical mechanical composter (Dutch Composter), a horizontal mechanical composter (BIOvator TM ), an open static pile yard and a roofed or covered static pile yard. This study includes a 5-year pro forma financial analysis and suggests recommendations regarding the most economically viable and environmentally appropriate alternatives. Based on the financial analysis and the current regulatory environment, the recommended compost system for a regional animal mortality facility is static piles under roof. However, alternative technologies may be feasible in other scenarios.

Several renderers ceased operations due to lower hide values linked to the recession and higher disposal costs associated with U.S Food and Drug Administration (FDA) regulations issued April 27, 2009 (Note 1)
Summary
In Missouri, all animal mortalities must be properly disposed within 24 hours. Five disposal options that have been acceptable, in order of preference, are rendering, composting, land filling, incineration, and burial (Fulhage, 1994). Several renderers ceased operations due to lower hide values linked to the recession and higher disposal costs associated with U.S Food and Drug Administration (FDA) regulations issued April 27, 2009 (Note 1). These events caused the industry to lack traditional animal disposal means. In Missouri, annual estimated beef, dairy, hog, horse, and deer mortalities total 264.9 million kg. Legend: Estimated kilograms of mortality, by county, for beef, dairy, deer, hogs, and horses; 34,832 to 1,106,086; 1,106,086 to 1,559,522; 1,559,522 to 2,147,245; 2,147,245 to 2,867,679; 2,867,679 to 3,482,771; 3,482,771 to 7,045,537. One study evaluated dead animal disposal costs as a future threat for Arkansas stocker cattle operators. This study evaluates the economic feasibility of 4 large animal composting systems
