The opportunity of using refuse-derived fuel (RDF) to produce fuel gas seems to be promising, and particularattention has been focused on alternative process technologies such as pyrolysis and gasification. Within thisframe, present work relates to experimental tests and obtained results of a series of experimental surveys onRDF gasification with steam, performed by means of a bench-scale rotary kiln plant at different processtemperatures, using thermogravimetry (TG) and infrared spectrometry (Fourier transform infrared, FTIR) tocharacterize the incoming material and online gas chromatography to qualify the gaseous stream. Experimentaldata show that the gas yield increases with temperature and, with respect to the gas composition, the hydrogencontent increases, mainly at the expense of the other gaseous compounds, which highlights the major extensionof secondary cracking reactions into the gaseous fraction at higher temperature. Syngas obtained at processingtemperatures of 950 
C or higher seems to be suitable for producing hydrogen for ammonia synthesis or forfuel cell applications, whereas, at lower processing temperatures, it seems usable for Fischer-Tropsch synthesis.The low organic content of solid residue does not suggest any other exploitation of the char apart from thelandfilling.
