The burning of a huge amount of nonrenewable fossil fuel has unfavorable consequences on the environment, climate, and living beings. The application of renewable bioenergy resources is considered an eco-friendly and sustainable substitute for fossil fuels. Biomass as a renewable resource has gained tremendous attention due to its potential to produce bioenergy in the form of solid, liquid, and gaseous fuels for running internal combustion engines in transportation, industries, and heat and electricity generation. This review critically examines the potential of biomass resources, scope, and technological advances in converting biomass to bioenergy. It also discusses the challenges, opportunities, energy policies, and prospects of biomass conversion to bioenergy within global and Indian contexts. Currently, several novel physical, chemical, and biological routes are used to produce renewable bioenergy. In India, crop biomass availability is estimated at around 500 million metric tons per year and can produce energy equivalent to 18,000 megawatts. It shows a bright future in energy production in India if adequately used.

“…After rice straw was pretreated with acid, the solid cellulose phase has been saccharified to produce sugar reduction using the crude enzyme secreted by the Trichoderma harzianum to produce reducing sugars. Pre-treated solid with glucose composition was utilized as substrate for ethanol production in (SSF) using S. cerevisiae and enzyme cellulase from Trichoderma as found superior as compared to the other fungal strains [34]. The microbial cellulase system is responsible for the generation of glucose from cellulose.…”

Recent years have seen an increase in the use of lignocellulosic materials in the development of bioproduct, biorefinery technologies have focused on process integration for the production of different valuable coproducts in order to reduce the overall processing cost. In this study, agricultural wastes from rice straw were used for the co-production of bioethanol and xylitol. Where bioethanol is produced from the cellulosic fraction and xylitol from the hemicellulose fraction after elimination of lignin using chemical pretreatments. The chemical treatment was carried out with diluted acid 2.5% at a 100 °C for 30 minutes , and then exposed the cellulosic fraction of the solid phase resulting from the chemical process to the enzymatic action of the fungus Trichoderma harzianum for releas sugars and fermented at a later stage using Saccharomyces cerecvisae for bioethanol production in a simultaneous saccharification and fermentation process, The liquid phase hemicellulose fraction was exposed to action of Meyerozyma guilliermondii strain F22 (Pichia guilliermondii) for xylitol production. Resulting was accomplished yielding maximum concentrations and product yield were 32.6 g/L 0.39g/g and 20.1 g/L, 0.44g/g for bioethanol and xylitol respectively of the total glucose and xylose available in rice straw, the co-production of xylitol with ethanol in an integrated biorefinery would create economic benefits making the overall lignocellulose-based process more cost effective

“…To meet this exorbitant demand there is a necessity to quantify a number of unexplored feedstock in order to meet the concerned capacity production with its advancement. As per the availability of reports some of the successfully explored potential starchy sources like wheat 4,5 , corn 6,7 , barley 8,9 , sweet potato 10 , maize 11 , rice 12 , potato 13 , cassava 14 and waste food grains 15 already has gained importance with defined technology and resources. Though these food crops have a huge demand in agriculture, there are all possibilities that they may pose threats of food vs. fuel conflicts 16 .…”

Current technologies for the production of biofuels from various renewable feedstocks have considerably captured vast scientific attention due to the fact that they can be used as an alternative fuels. Bioethanol being one of the most interesting biofuels and due to its positive impact on the environment has been categorised significantly in terms of scientific and technological investments. The aim of this study was to investigate, tubers of Amorphophallus paeoniifolius biomass as a feedstock for bioethanol production. The composition analysis of A.paeoniifolius tubers revealed high carbohydrate content (78.30 ± 0.33%). The feedstock was subjected to physicochemical pretreatment by treating with dilute acid followed by pressure cooking. The pretreatment factors were optimized by CCD using RSM approach. The optimum condition was found to be 1.32%v/v of HCl, 5.83%w/v of Elephant Foot Yam Biomass and 66.84 min of pressure cooking time yielding 45.87 g/L of total sugar. The second order polynomial equation was generated for the saccharification of the biomass and validated with R2 0.89. The fermentation of pretreated biomass in the presence of Saccharomyces cerevisiae MTCC170 yielded 22.12 ± 0.62 g/L of bioethanol at 120 h utilising 92% of initial total sugar. The resultant ethanol yield and productivity was estimated to be 0.51 g/g and 0.30 g/L.h respectively. The Gompertz model equation was applied to experimental data using nonlinear regression with the least square method and the kinetic fermentation parameters such as maximum ethanol concentration (Pm), production rate (rpm) and lag phase (h) were estimated to be Pm =21.90 g/L, rpm =0.57 g/L.h and tL =8.22 h.
