摘要: Infectious prions (PrPTSE) contribute to horizontal transmission of transmissible spongiform encephalopathies. Specified risk material (SRM) wastes and wastewater generated from slaughterhouses rendering plants represent a potential reservoir PrPTSE. Approved disposal practices for SRM that ensure destruction PrPTSE, including thermal or alkaline hydrolysis at 150°C–180°C under 4–12 atmospheres incineration, gasification combustion 1000°C, are expensive challenging implement in commercial slaughter facilities. Consequently, large portion the Canada is rendered buried landfills, whereas they incinerated considerable cost Europe. Alternatives these have been proposed include anaerobic digestion composting. These biodegradative processes offer advantages less energy intensive, CH4 can be used cogeneration end products as fertiliser. In addition, advanced ozonation liquid fraction...
