Book Description
Three studies were completed to address common challenges related to composting mass animal mortalities. The first study investigated the impact of water-based depopulation foam (WBDF) and straw on composting whole swine carcasses. For trial 1 (148 days), two windrows were constructed, and each was split into two halves: one half including WBDF and the other without. One windrow core consisted of sawdust and carcasses; the other windrow core consisted of sawdust, carcasses, and chopped rye straw. For trial 2 (101 days), two windrows were constructed, both containing WBDF. One windrow core consisted of sawdust and carcasses, whereas the other windrow core consisted of sawdust, carcasses, and wheat straw. Windrows were turned on days 80 and 58 for trials 1 and 2, respectively. Continuous automatic temperatures, weekly handheld temperatures, percent moisture, pH, and totals of Nitrogen, Carbon, organic matter, ash, Phosphorus, and Potassium were measured. Pathogen-destructive temperatures (≥55 °C, ≥131 °F) were achieved in all treatments for both trials. Compacted straw during turning and intact straw at designated trial endpoints was observed. In conclusion, data provided evidence that whole swine carcasses ± WBDF will decompose in a windrow core of sawdust ± straw. The second study investigated the composting efficacy of ground turkey carcasses blended with different amounts of carbon amendment for 50 days. Mechanically ground turkey carcasses were mixed with carbon amendment to achieve four different core compost ratios (weight/weight): 0.25:1; 0.5:1; 0.75:1; and 1:1. Compost mixtures were placed into 208-L (55-gal) reactors that simulated a full-sized windrow. Each reactor had a base and cap of carbon amendment. Continuous automatic temperatures and compost weight, volume, bulk density, porosity, percent moisture, total Nitrogen, and total Carbon were measured. All treatments were able to reach thermophilic temperatures (43-63 °C, 110-150 °F) and effectively decompose carcass tissue. Data indicated that composting ratios evaluated could all be scaled up for future studies. The third study investigated the effects of poultry carcass grinding and core carbon amendment optimization on mortality composting efficiency, in both 208-L (55-gal) reactors and full-sized, outdoor windrows. Four reactors and four windrows were constructed from turkey carcasses and carbon amendment which were passed concurrently through a horizontal grinder according to each of the following carbon:carcass ratios (w/w): 0.25:1, 0.5:1, 0.75:1 and 1:1. A fifth whole carcass windrow was also created. Windrows were each turned three times over a 92-day period; compost within each reactor was mixed three times over a 56-day period. Weekly handheld temperatures, visual observations, and soil samples were collected in the windrow trial. Carbon dioxide emissions and compost weights and volumes were measured in the reactor trial. Continuous automatic temperatures, bulk density, percent moisture, pH, and totals of Nitrogen, Carbon, organic matter, ash, Phosphorus, and Potassium were measured in both trials. Thermophilic composting temperatures were achieved in all treatments of both trials. Additional results indicate physical and chemical similarities across treatments upon completion of composting. In total, data suggested that ground carcasses could fully decompose with as much as a 75 percent reduction in core carbon amendment.

Book Description
Animal disease outbreaks pose many challenges for response authorities that can impact livelihoods, food security, and the environment. Proper disposal of animal carcasses that die or are culled during the outbreak is a key component of a successful response to a disease outbreak because it helps prevent or mitigate the further spread of pathogens and in case of zoonotic disease, to further protect human health. The practical guidelines presented hereby provide carcass and related waste management considerations and recommended procedures for use by Veterinary Services and other official response authorities when developing animal disease outbreak containment and eradication plans. The guidelines apply to animal disease outbreaks of varying sizes, whether the outbreak is isolated to a single premise or spans a region to cover numerous premises. However, they are focused on small to medium-sized holdings in countries without access to engineered landfills, rendering plants or controlled incinerators. The guidelines are written in the spirit of “keep it simple and doable”, considering the limited human and financial resources that many countries are constrained with. Its presentation and practical approach ensure that countries will find it very useful for their emergency operation procedures toolbox. Further, the guidelines directly contribute to the one-health approach by protecting the health of animals, humans, and the environment.

Book Description
This fact sheet provides an overview of the composting process and how it can be applied to the disposal of dead poultry & livestock on the farm. The information presented is based on the bin-type composting unit. Topics covered include the advantages of composting mortalities, planning & sizing the unit, designing & constructing the unit, getting ready to compost, choosing the compost substrate, the composting cycle, and managing the composting process. Appendices include a worksheet for sizing the unit, a table of estimated mortality rates & weight of various animals, and a composting record sheet.

Book Description
The Composting Handbook provides a single guide to the science, principles and best practices of composting for large-scale composting operations facing a variety of opportunities and challenges converting raw organic materials into a useful and marketable product. Composting is a well-established and increasingly important method to recycle and add value to organic by-products. Many, if not most, of the materials composting treats are discarded materials that would otherwise place a burden on communities, industries, farms and the environment. Composting converts these materials into a valuable material, compost, that regenerates soils improving soils for plant growth and environmental conservation. The Composting Handbook expands on previously available resources by incorporating new information, new subjects and new practices, drawing its content from current scientific principles, research, engineering and industry experience. In both depth and breadth, it covers the knowledge that a compost producer needs to succeed. Topics include the composting process, methods of composting, equipment, site requirements, environmental issues and impacts, business knowledge, safety, and the qualities, uses and markets for the compost products. The Composting Handbook is an invaluable reference for composting facility managers and operators, prospective managers and operators, regulators, policy makers, environmental advocates, educators, waste generators and managers and generally people interested in composting as a business or a solution. It is also appropriate as a textbook for college courses and a supplemental text for training courses about composting or organic waste management. - Created in conjunction with the Compost Research and Education Foundation (CREF) - Includes the latest information on composting and compost, providing the first comprehensive resource in decades - Written with focus on both academic and industrial insights and advances
