The present work shows the initial results of the evaluation of production and quality of the landfill gas to energy. Parameters of quality, pressure exerted by the system and volume of extracted landfill gas had been monitored. From the accompaniment of these parameters, three different analyses in different situations could explain the behavior of the wells: one analysis of wells in different depths, and two comparison analyses: (a) wells hardwired to the system of collection for active extraction; and (b) wells not hardwired to the collection system, with passive extraction. The results demonstrated that wells at intermediate deep have the highest yields and quality of gas and wells with passive extraction in relation to the active ones had significant differences of the monitored parameters.
