Abstract

An alternative method for the production of renewable fuels from rendered animal fats (pretreated using methods 1-5 or method 7 as described in Annex IV of Commission Regulation (EC) No 2011/142) and used cooking oils, derived from Category 3 animal by-products, was assessed. The method is based on a catalytic co-processing hydrotreatment using a middle distillate followed by a stripping step. The materials must be submitted to a pressure of at least 60 bars and a temperature of at least 270°C for at least 4.7 min. The application focuses on the demonstration of the level of reduction of spores from non-pathogenic spore-forming indicator bacterial species ( and ), based on a non-systematic review of published data and additional extrapolation analyses. The EFSA BIOHAZ Panel considers that the application and supporting literature contain sufficient evidence that the proposed alternative method can achieve a reduction of at least 5 log in the spores of and a 12 log reduction in the spores of . The alternative method under evaluation is considered at least equivalent to the processing methods currently approved in the Commission Regulation (EU) No 2011/142.

摘要

评估了一种从提炼动物脂肪(使用欧盟委员会法规(EC)No 2011/142附件IV中所述的方法1 - 5或方法7进行预处理)和来自第3类动物副产品的废食用油生产可再生燃料的替代方法。该方法基于使用中间馏分进行催化共处理加氢处理,随后进行汽提步骤。材料必须在至少60巴的压力和至少270°C的温度下保持至少4.7分钟。该应用基于对已发表数据的非系统性综述和额外的外推分析,重点展示了非致病性产孢指示细菌物种( 和 )孢子减少的水平。欧洲食品安全局生物危害评估小组认为,该应用和相关文献包含充分证据表明,所提议的替代方法能够使 和 的孢子减少至少5个对数,使 的孢子减少12个对数。正在评估的替代方法被认为至少等同于欧盟委员会法规(EU)No 2011/142中目前批准的加工方法。
