In this study, “ranking was accomplished using a hybrid multi-criteria decision-making (MCDM) model based on the weight obtained using the analytical hierarchy technique”. It is proposed to use WSM to determine whether using locally accessible biomass is feasible. During pyrolysis, in order to improve the output of bio- oil, a number of criteria are set down for this goal. The suggested approaches are well-aligned with one another and perfectly replicate the trial results. “This study includes seven biomass alternatives and seven evaluation standards. Sugarcane bagasse is regarded as the best biomass material out of the other seven”. In order to establish its utility, the bio-oil produced from the biomass material with the highest ranking was examined using gas chromatography (GC) and Fourier-transform infrared (FTIR) spectroscopy for its physical, elemental, and chemical contents. The thermos chemical conversion process, in particular, is clarified by this research in novel ways. 1. INTRODUCTION When used in fuel cell electric vehicles, hydrogen is an emission-free fuel. Because of the limited quantities and variable prices of fossil fuels, traditional methods of producing hydrogen (such as steam methane reforming from natural gas) have large carbon footprints that have an adverse effect on long-term sustainability [1]. Methane Traditional technology is changing as energy demands rise due to higher process temperatures. This has a negative influence on the ecosystem [2]. Change Pathways for producing hydrogen need to be made simpler Make the switch to hydrogen-powered transportation. Waste-to-hydrogen (WH) is a dual-purpose process. a technique for controlling waste and creating low- carbon hydrogen. There are waste conversion technologies. Quantification and development of hydrogen generation involve the processes of gasification (thermochemistry) and fermentation (biochemistry), both of which are largely in their infancy [3]. But technology has shown itself to be effective. Reasonable hydrogen generation yield, adaptability to different meal combinations, and carbon neutrality [4]. In this situation, using WIH to address both the problems of climate change and renewable hydrogen production at once is a potential strategy. Sustainability of trash management and inventory In Scotland, 540.935 tons of residential garbage were burned, and 1.03 million tons were transferred to landfills in 2018 [5]. 5.76 million tons of CO2-equivalent were calculated as the carbon impact of household trash. Waste Regulations 2012 and the Scottish Government's Zero Waste Scheme have been developed. Make sure the nation makes progress toward better sustainability and trash management. These measures seek to lessen reliance on landfilling and burning as primary waste management techniques and to reduce their negative environmental effects disposal of waste [7]. Sentence of ban on biodegradable waste by 02025, a landfill is expected to be operational [8]. Because of this, current settings should be adjusted for waste management options like WtH based ones. Glasgow City Council carried out the project Strategies and tactics for managing trash and reducing one's carbon footprint. Glasgow's waste policy includes processing garbage and making it available as a resource, while also utilizing technology to increase waste efficiency and boost sustainability [9].
