The study analyzes the issue of rebuilding Ukrainian territories destroyed by military actions based on circular economy and environmental management. The analysis of pollution levels (Numbeo) in countries with military conflicts showed an average pollution level (62.1), which may influence the recovery process in Ukraine compared to countries with high pollution levels, such as Lebanon (89.4) and Syria (74.9). However, Ukraine has a low waste recycling rate (4.5%), which could complicate environmental recovery. The implementation of the circular economy in reconstructing Ukraine’s infrastructure and the waste recycling process is suggested based on mobile laser sorting installations. The technology of mobile laser sorting installations allows efficient sorting of various materials, including metals, plastics, and construction debris, which can reduce recovery costs and optimize the use of available resources. To reduce environmental consequences and improve post-war recovery, it is suggested that pollution monitoring strategies be developed, investments in implementing the circular economy should be increased, and modern waste recycling technologies should be adopted. The analysis of the international experience in the recovery of affected regions highlights the importance of integrating environmental strategies into the recovery process, particularly by increasing the waste recycling rate and utilizing advanced technologies.
