Energy and water efficient continuous sterilisation of ABP from food wastes for AD based energy and material recovery

从食物垃圾中对ABP进行节能和节水的连续灭菌，以实现基于AD的能源和材料回收C-TECH INNOVATION将开发一种创新和高效的灭菌系统，该系统采用高温欧姆加热技术，以实现对动物副产品（ABP）的安全，低能耗处理。欧姆加热是一种容积式加热技术，可以有效地处理几乎任何可泵送的流体，具有极高的能量效率（>95%）。该技术将为进入AD系统的材料的预处理提供一种改进的方法，通过·减少对水的添加要求·提高灭菌的能源效率·稳健的无污染操作·连续流动操作，有效杀灭整个材料中的微生物·通过集成到AD系统中的二次效益·通过现场AD沼气生产增加能量回收·安全回收用于肥料的材料（英国）动物副产品（ABP）的处理是英国数百个地方面临的挑战。进入屠宰场的所有动物中，约有50%的重量被从食物链中移除，并被归类为动物产品（ABP）。根据对人类健康的风险，这种废物被分为：极高风险（第1类）、高风险（第2类）或中等风险（第3类）。现行ABP法规（APBR）规定了各类材料的建议处理时间和温度，但法规208/2006允许在特定病原体减少达到规定水平的情况下采用替代方法处理ABP。有效的灭菌将是经济上可行的回收工艺的关键技术，因为目前的方法是能源密集型的，难以实施。所采用的创新灭菌策略还将提供原料的初步水解，这将增强并加速后续阶段的消化。

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.
