Abstract: In recent years, international issues have mainly focused on energy issues and environmental preservation. Energy production from fossil resources accounts for more than 70% of total global energy production with negative environmental impacts. this work focuses on used edible oils, the impacts of which pose a problem for our environment; the spillage of one liter of these oils is estimated at 1000 m2 of oily film on the surface of the water, thus preventing proper oxygenation of the latter. The objective of this study was to design and build a pilot system for the production of gas and very low voltage electricity using biodiesel from the recovery of used cooking oils. The methodological approach here has a particular interest for the methods of transesterification and thermoelectricity by Seebeck effect, implemented in real life after digital simulation of the system, for the realization of the pilot system. The results obtained show that the KOH catalyst has much more advantage than NaOH where we obtained a percentage of glycerin (34%). The highest yield (89.82%) is obtained with the KOH catalyst at a temperature of 65? C., a molar ratio of 6: 1 and a reaction time of 120 min; and in the electricity production phase, the results were low (5 volts) due to the thermoelectric components which have low voltage production efficiency and wind flows in the environment of the pilot system causing inconstancy of the flame leading to poor heating of the different modules. A constructive voltage boost solution has been provided to compensate for this variation in the heat flow in order to have a considerable voltage; this allowed us to reach 48 volts.
