This study used life cycle assessment to evaluate the environmental impact of anaerobic co-digestion (AcoD) and compared it against the current waste management system in two case study areas. Results indicated AcoD to have less environmental impact for all categories modelled excluding human toxicity, despite the need to collect and pre-treat food waste separately. Uncertainty modelling confirmed that AcoD has a 100% likelihood of a smaller global warming potential, and for acidification, eutrophication and fossil fuel depletion AcoD carried a greater than 85% confidence of inducing a lesser impact than the current waste service.
本研究采用生命周期评估方法评估了厌氧共消化（AcoD）的环境影响，并将其与两个案例研究区域的当前废物管理系统进行了比较。结果表明，AcoD 在除人类毒性以外的所有模型类别中对环境的影响较小，尽管需要单独收集和预处理食物垃圾。不确定性建模证实，AcoD 具有较小的全球变暖潜势的可能性为 100％，对于酸化、富营养化和化石燃料枯竭，AcoD 具有大于 85％的置信度，表明其对环境的影响小于当前的废物处理服务。
