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

能源和水高效的食品垃圾ABP连续灭菌，用于基于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，结合高温欧姆加热技术，允许安全，低能耗处理动物副产品（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（>95%）。该技术将通过以下方式为进入AD系统的材料的预处理提供一种改进的方法：•减少对水的添加需求•提高灭菌的能源效率•稳健的无污染操作•在整个材料中有效杀死微生物的连续流动操作通过集成到AD系统中获得二次效益•通过现场AD沼气生产增加能量回收•用于肥料（消化液）处理的材料的安全回收动物副产品（ABP）是一个存在于英国数百个地方的挑战。按重量计算，进入屠宰场的所有动物中约有50%被从食物链中移除，并被归类为按产品分类的动物。根据对人类健康的风险，这类废物被分类为：非常高风险（第一类）、高风险（第二类）或中度风险（第三类）。目前的ABP法规（APBR）规定了材料类别的推荐处理时间和温度，但是第208/2006号法规允许在特定致病菌达到指定水平的情况下，对ABP采用其他处理方法。高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，难以实施。所使用的创新灭菌策略还将提供原料的初步水解，这将增强和加快后续阶段的消化。

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.
