The main objective is to develop a new process synthesis based on the residual biomass waste for the energy production applied to the fruit processing plant with co-production of hot, cold thermal energy using biogas from the wood biomass and animal wastes. After carried out the bibliographical research about the current state of art technology, an engineering project had been developed with the use of the software Super Pro Designer V 4.9. Some simulations of processes of the fast pyrolysis, gasification, biodigestion, generation of energy have been realized including the system integration of energy production as innovation of the present work. Three cases study have been developed: first, the current process of conventional energy using combustion, another one with using combined pyrolysis and gasification, and the last one with biodigestion for combined power, heat and chilling. The results about the project investment and the cost analysis, economic viability and cash balance were obtained using software Orc2004. Several techno-economic parameters of the selected cases study involving process innovation were obtained and compared, where a better energy and materials utilization were observed in relation to conventional process. This project which is still in development phase, involves small scale energy integrated system design .The energy and the process integration cashew fruit production chain based on the clean technology process deign is made possible with significant improvement of the economy and ecology and optimum system configurations with viability and sustainability.
