This project focused on strengthening a network of communities in their efforts towards sustainable management of solid waste. The initiative of integrating the communities of El Ceibo, Palacio, Campo Dos, and Monte Rey, in the county of Pococí, Costa Rica, into a network developed from the interest of the community members in finding appropriate methods for solid waste management and environmental protection. This project was conducted in conjunction with EARTH University, MINAET (Ministry of Environment, Energy, and Telecommunications), and 25 active members from the communities, through meetings, workshops, and complementary activities. In two of these workshops, the main actors developed new ideas and techniques to extend the useful life, and generate new potential uses of, solid waste. The concepts of organization and leadership were reinforced in a third workshop, and strengthened through theoretical and practical approaches. One of the final results of the project was the projection of this community network at the national level with the crowning of the “ecological queen”. The work in organization and community leadership promoted the strengthening of social capital, which was important for the development and completion of this project. The members of the community highlighted the following as key elements in the success of the network: communication capacity, tolerance, respect, and teamwork. The experiences in this project can be applied as a model for community organization to resolve any issue of concern in a rural community.
