• Resumen

  • The use of forest soil for revegetating sealed urban landfills is a practice leading to economic and environmental problems. Recently, it has been demonstrated a suitable technique for minimizing soil needs in re-vegetation of closed urban landfill in which, the layer of fertile soil usually added for plants to settle and develop in such degraded substrate is replaced by a layer of the degraded soil amended with anaerobic sewage sludge. In this work we expose the phases and the design for the implementation of a pilot project for the re-vegetation with this procedure of a closed landfill of municipal solid wastes managed by GIRSA, in a collaborative research between CIDE (CSIC-UVEG-GV) , Entidad Pública de Saneamiento de Aguas Residuales de la Comunidad Valenciana and DAM, S.L. The closed landfill has a surface of 2,6 ha and its re-vegetation will be carried out by introducing native plants (annuals, bush and trees) after incorporation into the degraded soil of the anaerobic sewage sludge at the single dose of 60 tn/ha. Twelve plots of 20 m by 8 m will be employed to quarterly research of the effects on the soil and on the introduced vegetation of three doses (0, 60, 120 tn/ha) of the anaerobic sewage sludge.
