Supplementary files for "Embodied energy in preventable food manufacturing waste in the United Kingdom"Abstract:The food processing and manufacturing industry is the UK’s largest manufacturing sector and consequently a large consumer of natural resources and source of environmental impacts. Considerable research effort has been made to quantify and characterise food waste and energy consumption from the industry, enabling the sector to set targets for reductions which contribute to national targets and the UN Sustainable Development Goal 12.3, and to identify improvement measures to meet the targets. A gap in this research is a detailed estimation of the energy consumption which could automatically be avoided through preventing food waste in food manufacturing. This paper reports research which estimates the energy embodied in preventable manufacturing food waste in the UK using available data for 2014. Whilst the estimate of 106 GW h per year is a tiny proportion of the industry’s annual energy consumption, it is 1.75 percentage points of the main 20% energy efficiency improvement target and over half the contribution expected from energy management measures to improve energy efficiency. Preventing food waste in the factory could therefore also contribute significantly to energy efficiency and climate change targets with no extra effort.

补充文件：关于英国可预防食物制造业废弃物的能源消耗研究摘要：食品加工与制造业是英国最大的制造业部门，因此也是自然资源的大消费者以及环境影响的来源。为了量化并描述该行业的食物浪费和能源消耗，已投入大量研究努力，以便该行业能够设定减少目标，这些目标有助于实现国家目标和联合国可持续发展目标12.3，并确定改进措施以达成这些目标。在此研究中的一个缺口是对通过预防食物浪费在食品制造业中本可自动避免的能源消耗的详细估计。本文报告的研究利用2014年的可用数据估计了英国可预防的制造业食物浪费所蕴含的能源。尽管每年106吉瓦时的估计仅占行业年度能源消耗的一小部分，但它相当于主要20%能源效率提升目标的1.75个百分点，并且超过预期从能源管理措施中获得的能源效率提升贡献的一半。因此，在工厂中预防食物浪费也可以极大地促进能源效率和气候变化目标的实现，而无需额外努力。
