Generally, the activities of post-disaster waste management usually produce high carbon emissions, which can cause damage to the environment. However, the issue of carbon emissions in the post-disaster waste supply chain is neglected. Hence, this paper aims to propose a mixed-integer linear programming model to address the post-disaster waste processing supply chain network design problem with the consideration of a carbon tax policy. The proposed model is developed based on the concept of a mixed strategy of waste separation to reduce carbon emissions. Not only the carbon emission perspective but also the financial perspective for post-disaster waste supply chain management is determined in the objective function. The proposed model was verified and validated by employing a numerical example based on realistic data. Based on the numerical example, the results show that the implementation of a carbon tax policy with the mixed strategy for waste separation can reduce carbon emissions in the post-disaster waste supply chain efficiently.

一般来说，灾后废物管理活动通常会产生高碳排放，这会对环境造成破坏。然而，灾后废物供应链中的碳排放问题却被忽视了。因此，本文旨在提出一种混合整数线性规划模型，以在考虑碳税政策的情况下解决灾后废物处理供应链网络设计问题。所提出的模型是基于废物分离混合策略的概念开发的，以减少碳排放。目标函数中不仅确定了碳排放视角，还确定了灾后废物供应链管理的财务视角。通过采用基于现实数据的数值例子来验证和验证所提出的模型。根据数值例子，
