Dairy Cattle Mortality Management via Anaerobic Digestion
نویسنده
چکیده
With the decline in the number of rendering operations due to industry consolidation and concern about Bovine Spongiform Encephalopathy (BSE) transmission, disposal of dairy and beef cattle mortalities by rendering either is not an option or is prohibitively expensive in many areas of the United States. On-site burial remains an alternative in many states, but impact on ground water quality is of concern. Many landfill operators either refuse to accept livestock mortalities for disposal, or the cost is difficult for producers to absorb. Incineration, an option for carcass disposal, has high investment and operating costs and is complicated by regulatory compliance issues. Another disposal alternative is co-composting with a carbonaceous material such as sawdust or straw. However, both incineration and composting generally are more suitable for the disposal of small animal mortalities such as those from poultry operations.

Energetic and environmental benefits of co-digestion of food waste and cattle slurry: a preliminary assessment Authors:
The research evaluated the feasibility of centralised pre-processing and pasteurisation of source-separated domestic food waste followed by transport to farms for anaerobic codigestion with dairy cattle slurry. Data from long-term experiments on the co-digestion of these two substrates was used to predict gross energy yields; net yields were then derived from full system analysis using an energ...

Anaerobic digestion (AD) of biowastes is one of the most common ways to produce methane-rich biogas, which has considerable potential to replace the fossil fuel used in multiple applications, such as vehicular transportation, internal combustion engines, cogeneration of heat and power systems and many other systems. Many companies are involved in the design and construction of anaerobic digesti...

The performance of temperature-phased anaerobic digestion (TPAD) system in the stabilization of dairy cattle wastes at high solids concentrations has never been evaluated, though the process has been established as a feasible alternative to conventional mesophilic processes for the treatment of municipal wastewater sludges. In this study, the TPAD system operating at a retention time of 14 days...
متن کاملInactivation of Selected Bacterial Pathogens in Dairy Cattle Manure by Mesophilic Anaerobic Digestion (Balloon Type Digester)
Anaerobic digestion of animal manure in biogas digesters has shown promise as a technology in reducing the microbial load to safe and recommended levels. We sought to treat dairy manure obtained from the Fort Hare Dairy Farm by investigating the survival rates of bacterial pathogens, through a total viable plate count method, before, during and after mesophilic anaerobic digestion. Different mi...
