For instance, in Southeast Asia alone, the total quantity of the waste-to-energy capacity from landfill biogas plants and incineration plants accounts for over 323 MW, and this number is expected to double by 2022; by 2030, the realizable generation potential from renewable municipal waste in six Southeast Asian countries will amount to 17.26 TWh (Maw Maw Tun, et al, 2020). Over the past years, the Cities Project has organized and facilitated exchanges on waste management between cities and organizations to invite partners to share their good practices, experiences and lessons, as well as their challenges in waste management. In 2021, the Cities Project launched a pilot project titled “Waste Wise Koidu” in Koidu, Sierra Leone in cooperation with UN-Habitat, which aims to improve local capacity in waste management. In 2022, under the framework of the same pilot project, the Cities Project has witnessed the signing of SoI between Koidu and Kushtia, Bangladesh, and the constant improvement of local partners’ capacity in waste management.
