During the last decades there has been an increase in the generation of solid wastes in the world, in developing countries the situation has been specifically critical since in many cases there is no adequate treatment for the solid waste due to the scarcity of the resources and to the poor conscience of the real situation and possible consequences. This document presents the composting method as a suitable alternative for the treatment of solid waste in developing countries considering that its costs are not so high and that the composition of the solid waste is mainly organic. The analysis was based on a current literature review and on the study of some cases of composting projects, according to the results an operational guideline for the development of composting projects in developing countries was proposed. The guideline is composed of two main cores: the planning system and the evaluation system. The planning system supports the development of a composting project and the evaluation system is a base for the comparison of performance between different future cases.
