## 4 Conclusions  
The carried out research activity, supported by European Union's Horizon 2020 research and innovation program, aimed to realize an automated machinery, with different sizes depending on place where it has to be installed (domestic--residential use, restaurants as well as isolated mountain communities where the OFMSW's daily collection can be difficult), for targeted treatment of the conferred OFMSW by means of its transformation in an inertised, valorised and identifiable (namely traceable) products that can then be used for different purposes. The developed process will lead to several advantages compared to what generally happens today for OFMSW's disposal and treatment:  
* The inertization and stabilisation allow a harmless and advantageous lasting storability of the treated- OFMSW;
* The harmlessness over time guarantees the eco-sustainability regardless subsequent path of the OFMSW-derived panels-bricks produced by the machinery;
* The waste's valorisation allows an extension of the possibilities of its reuse;
* The Radio Frequency identification (RFID) by using suitable wide-band low-cost passive UHF tags allows the traceability of the machinery's products ensuring targeted and optimal management of the re-use or storage of the valorized products;
* The codified identification allows the computerized management ensuring advantages for the public entities and citizens. Specifically, in this paper two original processes (called dual and one step) for transforming the organic waste (OFMSW) into an inert, odorless and sanitized material were proposed. To this aim, new green composites were realized through the incorporation of the OFMSW finely ground in a thermosetting urea-formaldehyde (UF) based resin. OFMSW /UF composites produced with the two-step method were firstly analysed by dynamic rheological analysis, in order to select the optimal curing conditions, even in presence of OFMSW. The mechanical results obtained on the cured samples produced with both dual and one step processes, highlight that the OFMSW /UF composites are characterized by higher mechanical properties compared to the neat resin. This last result was attributed to a decreased water evaporation rate, due to the presence of OFMSW and, in turn, to a less porous composites structure, as confirmed by optical microscopy analysis. Both methods proposed in this paper could be considered suitable for the production for example of Medium-density fibreboard (MDF)-like panels for building applications or thermal and acoustic insulating waste-based bricks to be

A rough cost estimation of the developed procedure is presented in second part of the present paper, proving the potential cost saving compared to the neat matrix [17]. Such a cost estimation must account for the fact that, compared to the standard processing of the UF resin, an additional cost is given by the sterilization, but the production of the blend, allows to reduce the cost due to the reduced UF consumption. In addition, the detailed results on the mechanical and thermal specifications obtained by the OFMSW-derived bricks or panels, made using the prototype machinery described above at the design stage, will be illustrated in another scientific work being prepared but here we can anti-cipate that the obtained values will allow their use in the proposed applications based on the existing standards on the technical specifications and low emission level of free formaldehyde in the air. Finally, an important advantage of this project, in terms of the environmental impact, lies in the reduction of CO\({}_{2}\) emissions, since the organic waste, if not properly and quickly treated, becomes a source of carbon dioxide emissions.
