Best practices in the management of municipal solid waste in the context of smart cities

Abstract

With rapid urban growth, public management faces a major challenge: to promote sustainability in cities. Urban concentration brings with it a need for sustainable development in various aspects, such as quality of life, education, infrastructure, sanitation, transport, energy and security. In this context, smart cities emerge, which use technology as a tool to improve the quality of life in urban areas. One of the main challenges to achieve sustainability and achieve the goals of the Sustainable Development Goals (SDGs) is the efficiency in the management of municipal solid waste (MSW), due to the increase in waste generation resulting from the urbanization process. This research was based on a literature review that identifies good municipal solid waste management (MSWM) practices applied in several countries and also technological innovations in MSWM in the context of smart cities. The literature reveals that there are challenges to be faced in developing countries due to financial constraints and deficiencies in governance. Therefore, guidelines were developed that can help other cities to follow the example of smart cities and overcome these challenges. Among the guidelines identified for efficient MSW management, the following stand out: transparent governance, adequate legislation, environmental education, efficiency in segregation and selective collection, implementation of technologies and involvement of society. MSWM is key to achieving sustainability in cities. Smart cities offer opportunities to improve this management through the use of technology. However, it is important to consider the particularities of each context and face the existing challenges, seeking innovative solutions. Through the implementation of good practices and the engagement of society, it will be possible to build more sustainable and smart cities.
