Strategic and operational decisions in waste management, in particular with respect to investments in new treatment facilities, are needed due to a number of factors, including continuously increasing amounts of waste, political demands for efficient utilization of waste resources, and the decommissioning of existing waste treatment facilities. Optimization models can assist in ensuring that these investment strategies are economically feasible. Various economic optimization models for waste treatment have been developed which focus on different parameters. Models focusing on transport are one example, but models focusing on energy production have also been developed, as well as models which take into account a plant's economies of scale, environmental impact, material recovery and social costs. Finally, models combining different criteria for the selection of waste treatment methods in multi-criteria analysis have been developed. A thorough updated review of the existing models is presented, and the main challenges and crucial parameters that need to be taken into account when assessing the economic performance of waste treatment alternatives are identified. The review article will assist both policy-makers and model-developers involved in assessing the economic performance of waste treatment alternatives.
由于多种因素的影响，包括废物数量的持续增加、对有效利用废物资源的政治要求以及现有废物处理设施的退役，需要在废物管理方面做出战略和运营决策，特别是在新处理设施的投资方面。优化模型可以帮助确保这些投资策略在经济上是可行的。已经开发了各种针对废物处理的经济优化模型，这些模型侧重于不同的参数。专注于运输的模型就是一个例子，但也开发了专注于能源生产的模型，以及考虑工厂规模经济、环境影响、材料回收和社会成本的模型。最后，还开发了将多标准分析中选择废物处理方法的不同标准结合起来的模型。本文对现有的模型进行了全面的更新回顾，并确定了评估废物处理替代方案的经济性能时需要考虑的主要挑战和关键参数。这篇综述文章将有助于参与评估废物处理替代方案经济性能的政策制定者和模型开发者。
