“…In addition to its many uses in the food and beverage industries, lactic acid and its derivatives also have a wide range of applications in the pharmaceutical, cosmetic, and manufacturing industries [91,92]. Numerous studies have demonstrated that rice straw can be utilized to make second-generation biofuels [47,[93][94][95][96]. Typically, bacteria and yeast turn carbohydrates into lactic acid and sugars into alcohol.…”

The quantity of organic waste generated by agricultural sectors is continually increasing due to population growth and rising food demand. Rice is the primary consumable food in Asia. However, many stakeholders follow a linear economic model such as the “take–make–waste” concept. This linear model leads to a substantial environmental burden and the destruction of valuable resources without gaining their actual value. Because these by-products can be converted into energy generating and storage materials, and into bio-based products by cascading transformation processes within the circular economy concept, waste should be considered a central material. This review examines the composition of rice straw, bran, and husks, and the procedures involved in manufacturing value-added goods, from these wastes. Moreover, starting with an extensive literature analysis on the rice value chains, this work systematizes and displays a variety of strategies for using these by-products. The future development of agricultural waste management is desirable to capitalize on the multi-functional product by circulating all the by-products in the economy. According to the analysis of relevant research, rice straw has considerable potential as a renewable energy source. However, there is a significant research gap in using rice bran as an energy storage material. Additionally, modified rice husk has increased its promise as an adsorbent in the bio-based water treatment industry. Furthermore, the case study of Sri Lanka revealed that developing countries have a huge potential to value these by-products in various sectors of the economy. Finally, this paper provides suggestions for researchers and policymakers to improve the current agriculture waste management system with the best option and integrated approach for economic sustainability and eco- and environmental solution, considering some case studies to develop sustainable waste management processes.

“…Typically, bacteria and yeast turn carbohydrates into lactic acid and sugars into alcohol. Trichoderma reesei, which was derived from decaying rice straw waste, produces cellulases that break down cellulose in the rice straw to glucose, which is then fermented with yeasts such as S. cerevisiae to make ethanol [93,97,98].…”

“…Alcohol emerged as an alternative to petroleum fuel for its partial or fully replacement. Biomass based alcohol are considered as renewable in nature and reduces overall well‐to‐wheel carbon dioxide (CO 2 ) emissions 7‐9 . Lower molecular weight alcohols like methanol, ethanol and butanol are utilized in fuel blends to reduce emissions without significantly affecting the performance 10,11 .…”

Increasing air pollution and implementation of stricter emission regulations led to the research for the clean combustion concept of combustion engines. To resolve this concern, it is important to look for a clean and stable combustion concept that can adapt easily to an old existing engine as well as newer engines. The present study was performed to investigate the combustion stability and emission for blends of methanol (M), ethanol (E), and butanol (B) to evaluate the effect of their inherent oxygen content. Alcohol blends were prepared for two different oxygen mass fractions of 2.5% and 5% oxygen, m/m (defined as M2.5, E2.5, B2.5 and M5, E5, B5). For this, different volume fraction of respective alcohol was required (M2.5 and M5 contained 5.2% and 10.3% methanol respectively, E2.5 and E5 contained 7.4% and 14.8% ethanol respectively, B2.5 and B5 contained 11.7% and 23.3% butanol respectively).Detailed combustion analysis was performed for the alcohol blends (2.5% and 5% oxygen mass fraction) using the parameters like cycle-to-cycle analysis, coefficient of variation, combustion phasing etc. M5 showed the better stable combustion considering the lowest coefficient of variation for CA50 and indicated mean effective pressure. Moreover, the performance of E5 showed improved efficiency with brake thermal efficiency (BTE) of 27.94% and reduced brake specific fuel consumption. Significant reductions in hydrocarbon (HC), smoke and carbon dioxide (CO 2 ) emissions were recorded for 2.5% and 5% oxygenated condition. M5 showed lowest emission level among tested fuel with 20% lower oxide of nitrogen (NO) and 50% lower HC.
