The increase of world population increases the solid waste. In Lebanon, two years ago, the problem of waste management appeared as one of the big problems to deal with. There is still no final solution for this problem. In this work, we studied different methods for waste management, and we proposed a hybrid system in the aim to optimize the solution by decreasing the pollution with acceptable price.Our system uses the gasification technique to produce synthesis gas; consisting of hydrogen and methane, from the daily generated waste. This gas will be then used by fuel cells to produce electrical and thermal energies. An organic waste rate is recovered by anaerobic digestion to produce biogas rich in methane. The thermal energy required for the gasification technique is recovered by cogeneration of the fuel cell and by an additional contribution of the biogas combustion.This work comes as a solution to two major problems in the Lebanon: the first one is the management of household waste and the second is the insufficient electrical energy produced. Our method increases the electrical efficiency and decreases the CO2 emission in comparison with traditional organic waste treatment methods. Additionally, using our method, we will be able to produce enough electricity to serve more than 38,000 houses at low CO2 emission using the waste generated by Tripoli.
