根据2016年美国的质量流分析，制造和农场生产阶段对美国食品供应链中的食品损失和浪费贡献最大，并且它们的回收率也最高。在这里，我们估计质量流以及食品损失和浪费沿着美国食品供应链的10个商品组和9个管理途径，为设计有效的战略，以减少，回收和恢复食品损失和浪费提供了一个基线。我们估计，2016年美国食品供应链中的食品损失和浪费总量为3.354亿公吨。水蒸发（19%），回收（55%）和填埋，焚烧或废水处理（23%）占损失和废物的大部分。消费阶段占57%的食物损失和废物通过填埋，焚烧或废水处理处理。制造业是造成食物损失和浪费的最大因素（61%），但回收率很高。高需求，易腐产品占食物浪费的67%。我们建议，为基础设施提供资金和激励早期食品捐赠可以提高供应链的效率和可持续性，促进FLW收集和回收沿着美国FSC，并改善消费者教育，以走向循环经济。
The manufacturing and on-farm production stages make the largest contribution within the US food supply chain to food loss and waste, and they also have the highest recycling rates, according to a mass flow analysis for the US in 2016.Reducing food loss and waste can improve the efficiency of food supply chains and provide food security. Here we estimate mass flow as well as food loss and waste along the US food supply chain for 10 commodity groups and nine management pathways to provide a baseline for designing efficient strategies to reduce, recycle, and recover food loss and waste. We estimate a total food loss and waste of 335.4 million metric tonnes from the U.S. food supply chain in 2016. Water evaporation (19%), recycling (55%), and landfill, incineration, or wastewater treatment (23%) accounted for most of the loss and waste. The consumption stage accounted for 57% of the food loss and waste disposed of through landfill, incineration, or wastewater treatment. Manufacturing was the largest contributor to food loss and waste (61%) but had a high recycling rate. High demand, perishable products accounted for 67% of food waste. We suggest that funding for infrastructure and incentives for earlier food donation can promote efficiency and sustainability of the supply chain, promote FLW collection and recycling along the U.S. FSC, and improve consumer education in order to move towards a circular economy.
