In that way, the inadequate management of Urban Solid Wastes appears as a problem that requires a solution in most of urbanizations in argentinean territory (World Bank-2007-Environmental Evaluation of USW in Argentina”). The compost on lines was studied as an alternative of management of waste of Mar del Plata, using organic fraction of USW and wood chip (bulking agent), evaluating the process during summer and winter (relations waste:bulking agent 1:1, 2:1 and 1:0) mixing as necessary to keep aerobic conditions. Evolution parameters were registered in the field and in the laboratory (physico-chemical and bacteriological analysis) from solids and leaches. The results of winter experiment are presented (2009), while summer test is still in process. The data confirmed the feasibility of the process in the weather conditions and USW quality of the examined area. 1 Moschione Eleonora, Mar del Plata National Technological University, [email protected] 2 Menna Máximo, Mar del Plata National University-, [email protected] 3 Ronco Alicia, La Plata National University, [email protected] 4 Gonzalez Froilan, Mar del Plata National University, [email protected] 5 Saubidet Alejandro, Mar del Plata National Technological University, [email protected] 6 Ricci Flabian, Mar del Plata National Technological University, [email protected] 7 Garcia Cristina, Mar del Plata National Technological University, [email protected] 8 Katz Carina, Mar del Plata National Technological University, [email protected] -1-
