Corn stalks are a valuable agricultural byproduct that has low commercial value. Another option is to use agricultural biomass for bioethanol production. The pretreatment and hydrolysis processes have seen significant advancements in recent years, which has resulted in better sugar yields. The mildly alkaline pretreatment that was economically the lowest cost was chosen. The pre-treatment, hydrolysis, and fermentation processes of corn stalks are the primary focus of this work. Saccharomyces cerevisiae has shown the most promising results in terms of ethanol yield, final concentration, and productivity. The maximum ethanol yield (18.578 g/L) was achieved on the third fermentation day at 35°C using 2% (w/v) yeast S. cerevisiae. A biorefinery that uses corn stalks could be the solution for producing high-value-added goods in the near future in a manner that is environmentally friendly, economically practical, and efficient.

The usage of biomass as a source of energy production is one of the components of the program for sustainable bioenergy inputs, scientific and technological expansion, and new enterprise development. Among various types of biomass, forest biomass has attracted considerable attention given its abundance and variations. Forestry biomass can be used to replace fossil fuels and has many advantages. This study evaluated Thailand's potential for forestry biomass development based on market and technology. Thailand increased biomass utilization. Potentially, forest residues can be a source of renewable energy. Producing bioenergy from biomass is one of the viable options that might be implemented in Thailand to address the country's energy needs. This study tests whether biogas intervention is associated with higher forest leaves biomass from the widespread plants of Afzelia xylocarpa, Pterocarpus macrocarpus, Shorea obtuse, Xylia xylocarpa, Dipterocarpus alatus, and Tectona grandis in Phrae Province in Northern Thailand. It is important to understand the physical and chemical properties of this biomass in order to maximize its use for biogas production. According to the findings of this study, using tree leaves as a feedstock for biogas generation represents an opportunity to reduce the need for fossil fuels and fuel imports. However, more research is needed, namely to determine the economics of implementing the use of native tree leaves for biogas production.
