Selection of sustainable lignocellulose biomass for second-generation bioethanol production for automobile vehicles using lifecycle indicators through fuzzy hybrid PyMCDM approach

Petroleum prices are increasing day by day due to the essential requirement of fuel to run automobiles, agricultural engines and standby power plants. More utilization of fossil fuels leads to global warming, environmental pollution, ozone depletion, and climate change. The second-generation ethanol is produced from various feedstock, including agricultural wastes and lignocellulose biomass sources doesn't affect the food security in many countries and the blending of bio-ethanol in gasoline reduced the greenhouse gas emissions. As large quantity of Lignocellulose biomass is available in India; the present study aims to select sustainable Lignocellulose biomass for the production of second-generation ethanol in Indian context. Five Lignocellulose biomass (Sugarcane Bagasse, Rice straw, wheat straw, Moringa, and Vetiver) were identified and prioritized using MultiCriteria Decision Making (MCDM) methodology. This study followed the Hybrid MCDM approach to prioritize the Lignocellulose biomass. Python-based Evaluation Based on Distance from Average Solution (PyEDAS) MCDM algorithm was developed, and the final ranking is compared with COmplex PRoportional ASsessment (COPRAS), Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) & Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE). From the results, Vetiver grass ranked as the best alternative, and Sugarcane bagasse ranked as the worst alternative among five Lignocellulose biomass sources.

Automated summary

Petroleum prices are increasing due to the essential requirement of fuel, but this study explores the potential of second-generation ethanol produced from sustainable lignocellulose biomass sources. The study uses a MultiCriteria Decision Making (MCDM) methodology to identify and prioritize five biomass sources in India. The results show that Vetiver grass is the best alternative, while Sugarcane bagasse is the worst alternative.
