We present a supply chain optimization framework to analyze economic and environmental benefits of recovering biogas, caproic acid (C6), and caprylic acid (C8) from different sources of organic waste. The framework makes simultaneous decisions on technology selection, sizing and placement, and transportation logistics. We consider livestock manure, wastewater sludge, and food waste generated in urban areas, dairy farms, wastewater treatment facilities, and landfills. Case studies for the State of Wisconsin reveal that the deployment of biogas recovery technologies offers the most environmental benefits but it is not economically viable while the deployment of C6/C8 recovery technologies is economically viable but provides limited environmental benefits. The simultaneous deployment of biogas/C6/C8 technologies (in the form of hybrid recovery systems) achieves both objectives. We also show how to use our framework to guide experimental research by providing yield targets for technologies that would achieve desired social welfare levels and rates of return.

分析有机废物中沼气和脂肪酸的供应链框架

我们提供了一个供应链优化框架，以分析从不同有机废物来源回收沼气，己酸（C6）和辛酸（C8）的经济和环境效益。该框架在技术选择，规模和布局以及运输物流方面同时做出决策。我们考虑在城市地区，奶牛场，废水处理设施和垃圾填埋场中产生的牲畜粪便，废水污泥和食物垃圾。威斯康星州的案例研究显示，沼气回收技术的部署可带来最大的环境效益，但在经济上不可行，而C6 / C8回收技术的部署在经济上可行，但环境效益有限。同时部署沼气/ C6 / C8技术（以混合回收系统的形式）可以实现两个目标。我们还展示了如何通过使用我们的框架来指导实验研究，从而为实现期望的社会福利水平和回报率的技术提供产量目标。
