Reuse of msw organic fraction and drinking water sludge in geo-environmental application

Reuse of organic fraction recovered from Municipal Solid Waste (MSW) is limited because of environmental pollution risks caused by the use of materials recovered. The legislation is currently geared to allow the use of a very small quantity for agronomic and environmental restoration, about 10 tons/ha*year. In these quantities, cost control and environmental monitoring pre and post application, are often inappropriate to the benefits obtained. This paper reports the preliminary results of a study aimed at evaluating the quality and environmental aspects of land reconstructed (“bio-soil”) from drinking water sludge and organic stabilized fraction from municipal solid waste, used in much greater quantities than the usual standard for "massive" applications in environmental actions or replacement of natural nursery soils.
