Abstract In this work, the possibility of valorization of biomass residues have been investigated by means of experimental analysis on a small scale open top gasifier and the application of a thermodynamic model. Moreover the effect of the torrefaction pretreatment will be investigated through the gasification of torrefied pellet (processed a two different temperatures). In the first part, the analysis of the data elaborated starting from national and local database (ISTAT Istituto Nazionale di Statistica and the Chamber of Commerce of Bolzano Province) with the aim of possible alternative feedstocks for a gasification process are presented. In the second part, the results of the laboratory (Laboratory of Free University of Bozen) analysis performed on the chosen materials are shown. In the third part, the data obtained from the gasification in a small scale gasifier have been elaborated and presented. The effect of different percentages of bark in wood chips have been investigated with the aim of evaluating the possibility of its valorization in a gasification plant. The results of the gasification tests have been also employed for the calibration of a model used for the gasification simulation of a compost out of specification (over sieve material) produced from a combined process of anaerobic digestion and composting. Finally, an economic analysis on small-medium scale gasification plants applications have been performed in order to understand if a practical use of the analyzed feedstocks is possible (considering also the case of incentive absence). The evaluation of the possibility of residual valorization is of primary importance not only to achieve higher standards in terms of “zero waste” processes, but also for a future economic development of the technology, characterized by high potential of development, but, at the state of the art, by high costs of investments and management. In dieser Arbeit kann die Entwicklung von Biomasse genutzt werden Mit anderen Worten, die Wirkung des Turms wird durch die Vergasung von torrefizierten Pellets (die bei zwei verschiedenen Temperaturen verarbeitet werden) erzielt. ISTAT Nationales Statistikinstitut und Handelskammer der Provinz Bozen (ISTAT) mit Analyse der Datenverarbeitung. Im zweiten Teil die Ergebnisse der Laboranalyse (Labor der Freien Universität Bozen) Im dritten Teil wurden die Daten aus der Vergasung in einem kleinen Vergaser aufbereitet und präsentiert. Die Auswirkung unterschiedlicher Rindenwerte in Hackschnitzeln wurde untersucht. Die Ergebnisse des Vergasungstests sind die Hauptmerkmale des Vergasungstests. Schließlich wurde eine wirtschaftliche Analyse für Vergasungsanlagen im kleinen und mittleren Maßstab entwickelt, um zu verstehen, ob eine praktische
