Biomass is considered a renewable resource because of its short life cycle. Biofuels generated from biomass have the potential to replace fossil fuels. All the carbon in biomass comes from the atmosphere as it grows and when it is burnt, the carbon is released back into the environment. As a result, biomass is regarded as a carbon-neutral fuel. For these reasons, bioenergy production is a viable option for extending the life of finite fossil fuel sources, reducing greenhouse gas emissions and mitigating global warming and climate change. Biomass may be transformed to biofuels in several ways, including physical, thermochemical, chemical, and biological processes. Biofuel and bioenergy technologies play a critical part in renewable energy development due to the merits of bioenergy for environmental sustainability.

Despite the fact that energy demands are continuous, biomass supplies are seasonal. Some biomass feedstocks have advantages over others in terms of production, harvesting, storage, and transportation. Compared to food crops, energy crops and nonfood biomass have advantages. Switchgrass and miscanthus are perennial energy crops that do not need replanting each year and do not need particular care or upkeep to thrive. Agricultural biomass wastes, on the other hand, have the potential to be low-cost feedstocks since they do not need additional space for biomass development, and the land now used for agriculture is owned by these biomass materials. Forest biomass is a valuable resource for the creation of biofuels and other high-value products. The high costs of harvesting and transporting, however, prohibit them from being extensively employed. Aside from the advantages and disadvantages mentioned above, different sources of biomass feedstocks do not have the same composition, uniform size and shape, or other features that have a major influence on the efficiency of conversion processes for a certain product. As a consequence, biorefinery biomass feedstocks must be standardised.
