Feasibility studies for the production of biofuels from waste and organic waste

(Case study: biodiesel and bioethanol)

With the population of 9 million people and counting, Tehran is facing significant transportation problems including the environmental pollution resulted from using fossil fuels in vehicles with major unfortunate consequences on the residents’ health. On the other hand, the huge amount of waste materials produced daily in such a big city is completely challenging. In this report, the focus is on extracting biofuels -as a “clean” and sustainable source of energy- from the organic waste materials for the purpose of replacing fossil fuels in transit vehicles (i.e. buses) and paratransit vehicles (i.e. taxis) in Tehran. Therefore, two types of biofuels (i.e., biodiesel and bioethanol) are studied and some worldwide and nationwide efforts to produce biodiesel and bioethanol are mentioned. Also, some pilot and commercial production plants for these two types of fuels are summarized. Finally, the amount of motor fuel which can be produced from organic waste in the city of Tehran is calculated alongside calculating its economic efficiency. It is shown that although it is possible to use biodiesel as the fuel of public buses in the city of Tehran, it is not economically efficient. On the other hand, it is shown that bioethanol produced from organic waste cannot be readily consumed and major challenges exist. It should be noted that if all technical challenges were addressed carefully, the investment to use bioethanol produced from organic waste in taxis would not be attractive for the private section. Such a project should be funded by the government or public sections.
