Energy and water efficient continuous sterilisation of ABP from food wastes for AD based energy and material recoveryC-TECH INNOVATION will develop an innovative and efficient sterilisation system incorporating high temperature ohmic heating technology to allow the safe, low energy processing of animal by product (ABP). Ohmic heating is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This technology will provide an improved method for the pre-treatment of materials entering AD systems by• reducing the requirement for water addition• improved energy efficiency in sterilisation• robust non fouling operation• continuous flow operation with effective microbial kill throughout the materialSecondary benefits through integration into an AD system• increased energy recovery through onsite AD biogas production• safe recovery of materials for use in fertilizers (digestate)Disposal of animal by-products (ABP) is a challenge that exists at hundreds of locations in the UK. Around 50% by weight of all animals entering abattoirs is removed from the food chain and is classified as Animal by Product (ABP). Depending on the risk to human health this waste is classified as; very high risk (catergory 1), high risk (category 2) or intermediate risk (category 3). The current ABP regulations (APBR) stipulate recommended treatment times and temperatures for the classes of material, however Regulation 208/2006 allows for alternative methods of treatment for ABPs if a specified level of reduction in specific pathogenic organisms is achieved.The efficient sterilisation will be the key enabling technology for an economically viable recovery process as current methods are energy intensive and difficult to implement. The innovative sterilisation strategies used will also provide a preliminary hydrolysis of feedstock which will enhance and speed up digestion in the subsequent stages.

对食物垃圾中的ABP进行能源和水的高效连续杀菌，以实现基于AD的能源和材料回收C技术创新将开发一种创新和高效的杀菌系统，结合高温欧姆加热技术，允许安全、低能量地加工动物副产品(ABP)。欧姆加热是一种体积加热技术，它可以有效地处理几乎任何可泵送的流体，具有极高的能源效率(&gt；95%)。这项技术将通过以下方式为进入AD系统的材料提供改进的预处理方法·减少加水需求·提高灭菌能效·稳健的无污染操作·连续流动操作，在材料中有效杀灭微生物·通过集成到AD系统实现二次效益·通过现场AD沼气生产提高能量回收·安全回收用于肥料(沼气)的材料·动物副产品(ABP)处置是英国数百个地点存在的挑战。进入屠宰场的所有动物中，约50%的重量被从食物链中移除，并被归类为副产品动物(ABP)。根据对人类健康的风险，这些废物被归类为：极高风险(1类)、高风险(2类)或中等风险(3类)。现行的总部基地法规(APBR)规定了各类材料的建议处理时间和温度，但第208/2006号法规允许在特定病原体减少到特定水平的情况下替代ABPS的处理方法。有效的灭菌将是经济上可行的回收过程的关键技术，因为目前的方法是能源密集型的，很难实施。使用的创新灭菌策略还将提供原料的初步水解，这将加强和加快后续阶段的消化。
