Due to the limited possibilities of FOS (Stabilized Organic Fraction) usage both for environmental restorations and landfill coverings, the selection of the bio-drying single flow process as a pretreatment for an high quality CDR (RDF-Refuse Derived Fuel) is currently the only alternative to dual flow Mechanical and Biological Treatment (TMB). The purpose of this study is the analysis of a real scale operating bio-drying process case by performance recording/analysis and consequent limits & strengths /Weaknesses identification in various usual/unusual conditions.

The strengths have been identified in the minimization of the FOS (Stabilized Organic Fraction) quantities and in the higher yield of CDR (RDF-Refuse Derived Fuel) on the total amount of incoming waste. Primary strength consist in better quality CDR (RDF-Refuse Derived Fuel) obtained by eliminating most of the problems related to the waste refining process subsequent phase, with the possibility of adopting bio-dried material refining techniques and technologies, not usable for wet waste, with the same yields.

Abstract
Due to the limited possibilities of FOS (Stabilized Organic Fraction) usage both for environmental restorations and landfill coverings, the selection of the bio-drying single flow process as a pretreatment for an high quality CDR (RDF-Refuse Derived Fuel) is currently the only alternative to dual flow Mechanical and Biological Treatment (TMB). The purpose of this study is the analysis of a real scale operating bio-drying process case by performance recording/analysis and consequent limits & strengths /Weaknesses identification in various usual/unusual conditions. Continuous monitoring system of biological process has been developed and optimized and a bio-chemical process model has been developed using experimental tests data. The strengths have been identified in the minimization of the FOS (Stabilized Organic Fraction) quantities and in the higher yield of CDR (RDF-Refuse Derived Fuel) on the total amount of incoming waste. Primary strength consist in better quality CDR (RDF-Refuse Derived Fuel) obtained by eliminating most of the problems related to the waste refining process subsequent phase, with the possibility of adopting bio-dried material refining techniques and technologies, not usable for wet waste, with the same yields.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
