Commercialization of bioethanol has recently intensified due to its market stability, low cost, sustainability, alternative fuel energy composition, greener output and colossal fossil fuel depletion. Recently, because of greenhouse intensity worldwide, many researches are ongoing to reprocess the waste as well as turning down the environmental pollution. With this scenario, the invention of bioethanol was hailed as a great accomplishment to transform waste biomass to fuel energy and in turn reduce the massive usages of fossil fuels. In this study, our review enlightens various sources of plant-based waste feed stocks as the raw materials for bioethanol production because they do not adversely impact the human food chain. However, the cheapest and conventional fermentation method, yeast fermentation is also emphasized here notably for waste biomass-to-bioethanol conversion. Since the key fermenting agent, yeast is readily available in local and international markets, it is more cost-effective in comparison with other fermentation agents. Furthermore, yeast has genuine natural fermentation capability biologically and it produces zero chemical waste. This review also concerns a detailed overview of the biological conversion processes of lignocellulosic waste biomass-to-bioethanol, the diverse performance of different types of yeasts and yeast strains, plusbioreactor design, growth kinetics of yeast fermentation, environmental issues, integrated usages on modern engines and motor vehicles, as well as future process development planning with some novel co-products.

Biorefineries are regarded as a key enabler to facilitate the transition toward a sustainable and low carbon bioeconomy. In this study, alternative lignocellulose biorefineries annexed to a typical sugar mill were investigated to co‐produce ethanol (EtOH), lactic acid (LA), and/or electricity, utilizing bagasse and a component of harvesting residues (brown leaves) as feedstock. Studied scenarios included EtOH as the sole product from glucose and xylose (Scenario 1), LA as the sole product from these two sugars (Scenario 2), EtOH from glucose and LA from xylose (Scenario 3), and EtOH from xylose and LA from glucose (Scenario 4), all of which were associated with some level of export electricity production. Aspen Plus® simulations of the scenarios were developed considering all supplementary units, such as evaporation, water treatment, boiler, and steam/power generation in addition to the process units required for the main product streams. Economic evaluation, energy assessment, and environmental life cycle assessment (LCA) were carried out on the developed simulations, in a multi‐criteria analysis of the desirability of each scenario. To service the combined energy demands of a sugar mill and annexed biorefinery, a 35 to 40% bypass of lignocellulose directly to the boiler section was required to achieve integrated scenarios that were energy self‐sufficient, i.e., not dependent on external (fossil) energy sources. Scenario 2 was economically most attractive with the highest internal rate of return (IRR) of 31.1%, whereas Scenario 1 had the lowest IRR of 10.0%. Scenarios 2 and 4 were economically the most robust, with the least sensitivity to variations in the key economic drivers, i.e., EtOH, LA and enzymes. The LCA suggested that LA producing scenarios introduced environmental burdens that were marginally higher than Scenario 1, due to higher consumption of processing chemicals. Overall, Scenario 4 was found to be the most desirable biorefinery scenario, by balancing financial and environmental considerations. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd
