1. Introduction
The main systems for solid municipal waste (SMW) management involve the separation of all recyclable materials and the last fraction, usually named refuse-derived fuel (RDF), which contains all non-recyclable materials with different particle sizes and variable moisture, depending on the efficiency of the management system [1,2,3]. Usually, due to its convenient calorific value, the dried RFD is used in the cement industry for the partial replacement of solid fuels [1].
To answer specific issues in the Integrated Management Center from Tarpiu, Bistrita Nasaud County, through the CleanTech Project, funded under the frame of POC 2014–2020 Structural Funds Programme, a complete characterization of produced RDF is under evaluation.
2. Materials and Methods
In this study, the RDF recovered from SMW separation was decomposed in a fixed-bed reactor and the condensable fraction was analyzed be gas chromatography coupled with mass spectrometry (GC/MS) using a Perkin Elmer analyzer.
3. Results
The main compounds in the liquid phase collected during the thermochemical decomposition in an oxygen-free atmosphere of tested RDF were identified. In Figure 1, the chemical structure of these compounds and their retention time are presented.

Main compounds identified by gas chromatography coupled with mass spectrometry (GC/MS).
4. Conclusions
By applying GC/MS analyses, the main compound released by the RDF in thermochemical applications can be identified, which allows a better control of post-treatment procedures efficiency.
