Abstract In the current period of energy development, it is very complex to produce energy from agricultural wastes due to the involvement of multiple criteria such as social, economical and environmental factors. In this study, a hybrid multi-criteria decisionmaking (MCDM) model based on the weight obtained from analytical hierarchy process (FAHP) has been utilized for ranking. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Evaluation based on Distance from Average Solution (EDAS) are proposed to evaluate the possibilities of utilizing locally available biomass. For this purpose, a number of criteria are defined from the viewpoint of yielding maximum bio-oil during pyrolysis. The proposed methods are having excellent agreement with each other, and they are exactly matched with the experimental results. This study consists of seven biomass alternatives with seven evaluation criteria. Out of seven selected biomass materials, sugarcane bagasse is ranked top. The experimental results confirmed the prediction with maximum bio-oil yield of 48.5 wt% obtained from sugarcane bagasse. At the end of the study, the obtained bio-oil from top ranked biomass material was analysed for physical, elemental and chemical compositions using Fourier-transform infrared (FTIR) spectroscopy and gas chromatography (GC) for its utility assessment. This study gives new insights into decision-making, specifically thermochemical conversion process. Keywords Multi-criteria decision-making . TOPSIS . EDAS . Biomass selection . Pyrolysis .

1 Introduction Energy is a necessity for human life, but current energy resources are forecast to be limited in the coming years with apparent destructive consequence to the environment. Currently the energy requirements for the world are satisfied by fossil fuels such as coal, petroleum, petroleum products and natural gas [1, 2]. The international energy auditing agencies are forecasting that the total world energy requirement will be increased by 50% from 2020 to 2035. They are

estimating that the total oil resources will be worn out within 40 years. The demand for the fossil fuels and its depletion are necessitating the researchers to find the possible alternative fuel. The alternate renewable energies are having capability of replacing conventional energy sources in most of their applications at aggressive long-term prices [3, 4]. The use of biomass as a source of energy is a promising option, since it is abundant and renewable [5]. Biofuels are providing guara
