Qualitative and quantitative analysis were considered for the development of the article and to achieve the established objectives, as follows: a) quantitative - through technical visits to Lapa composting plant in São Paulo, accelerated composting plant in Vancouver and urban gardens, for example, the Horta das Corujas; b) qualitative – it is considered analysis of standard techniques used for composting urban in order to identify which suit the characteristics of limited space of cities.
