Abstract
This review investigates the possibility of biobutanol as a renewable energy source for addressing the environmental issues associated with traditional carbon-based fuels. As energy demand rises, carbon emissions from fossil fuels exacerbate climate change, emphasizing the importance of sustainable, low-emission alternatives. Bioenergy, which is produced from organic waste via biochemical processes, is a possible replacement. Biobutanol, in particular, has an advantage over bioethanol due to its cleaner combustion and applicability for a variety of applications; nevertheless, the toxicity of biobutanol to its producing bacteria reduces production efficiency. Gas stripping recovery systems are presented as solutions for increasing output.
Renewable energy is classified into four types based on its source: edible crops, non-edible biomass (such as lignocellulose), cellular materials, and carbon capture. Currently, first-type renewables dominate, but agricultural concerns are moving the focus to non-food sources. Second-generation renewables, particularly lignocellulose, offer considerable benefits by exploiting whole plant biomass with minimum land needs. Biobutanol, a second-type renewable, is recognized for its ability to satisfy energy demands while promoting environmentally good activities. This analysis emphasizes biobutanol's potential for bioenergy, notably from agricultural waste, and advocates for more research into production upgrades.
