“…Fuels from plant sources are used in huge amounts. Biofuels are considered safe for the environment, improve energy security, and do not negatively affect the food market [8]. The need to acquire energy from other alternative sources arises from the fact that fossil fuels are limited in amount.…”

Energy use in agricultural production has been increasing faster than in many other sectors of the world economy. Owing to high energy consumption during the production of agricultural inputs, with mineral nitrogen fertilizers in particular, it is often questioned as to whether agricultural production is still energy efficient. The objective of this research was to evaluate the energy efficiency of different intensity systems for the production of semi-dwarf winter triticale cultivar ”Twingo”. Cultivar “Twingo” entered the Polish National List in 2012 as one of the best yielding. For this reason, it was used in this experiment to examine its response to basic agrotechnical factors. The field experiment was conducted in the Agricultural Experiment Station in Tomaszkowo in 2013–2015. Low-input, medium-input and high-input production systems were evaluated. The compared systems differed in nitrogen fertilization rates and the level of fungicide protection. The highest output/input ratio was noticed growing winter triticale in low-input production system. The most energy-consuming operation during winter triticale production in the compared systems was mineral fertilization. The high-input production system was significantly lower energy efficiency than the other systems (6.21, medium-input 5.95, low-input 8.19). The energy return on investment (EROI) ratio was low, but above 1, in all the analyzed technologies (low-input 1.30, medium-input 1.14, high-input 1.15). The energy value of the bioethanol produced was higher than the energy inputs into the production of raw material and its processing. The conversion of winter triticale grain to bioethanol proved that the EROI reached the most favorable value for the low-input production system.

“…Despite the debate on conventional biofuels, the use is inevitable because the convergent technologies and market are already established and cheaper than second-generation biofuels. The production of biofuel increased 17 % in 2010 compared to 2009 [16]. Ziolkowska [14] reports that the first-generation biofuel production was 37 billion gallons globally until 2017, accounting only for the transport sector.…”

Suitability of Biofuels Production on Commercial Scale from Various Feedstocks: A Critical Review

The growing demand for energy resources and the increase in greenhouse gas (GHG) emissions has given biofuels a lot of attention. Liquid biofuels can be a significant alternative for the transport sector. Generally, biofuels are categorized into four generations based on the feedstock. This review reports the availability, economic feasibility, and potential of biofuel feedstock in global scenario. Feedstock for first-generation biofuel comprises edible resources impacting the food supply. Second generation biofuels are based on different residual materials and nonedible fuel crops. Cost and technological limita-tions for commercialization hinders this option. Microalgae are the feedstock for third generation biofuels providing the highest yield compared to the other two generations. A scale-up to commercial level is not possible as this requires further development. Genetically modified microorganisms are used as a feedstock for fourth generation biofuel production with the highest possible yield. Third and fourth generation biofuels have potential to replace fossil fuels. This review recommends certain suggestions for sustainable biofuel production.

“…Energy security and global climate change are the two primary concerns globally, as the quest for sustainable energy ranks as one of the most pressing needs of the 21 st century [1][2][3][4]. Proper utilization of energy resources is an interesting debate currently on-going, and it is very essential to choose which source of energy must be used and why.…”

“…They are derived from biomass and include a wide range of fuels such as solid biomass, liquid fuels, and biogases [14]. Wood, saw dust, and waste bagasse are solid; ethanol, methanol, propanol, butanol and plants oil are liquid; while methane gas and syngas are examples of gaseous biofuels [3]. Biofuels have emerged as one of the most strategically significant sustainable fuel sources and are considered an important means of progress for limiting greenhouse gas emissions, improving air quality and finding new energetic resources [15].…”

Increased energy consumption coupled with the ongoing climate change are urging us to develop more sustainable energy alternatives, including biofuels produced from renewable biomass. Our heavy reliance on fossil-derived fuels has not only gained intense public attention in recent years, but has also prompted us to intensively study the production of sustainable biofuels from renewable energy sources via microbial fermentation. Owing to the recent advances and availability of state-of-the-art molecular tools, our knowledge about anaerobic microorganisms and their direct and indirect contributions in the production of different biofuels have increased tremendously. Anaerobic microorganisms are mainly utilized for commercial production of biofuels such as; biogas and fuel alcohols from renewable organic matter, while photosynthetic microorganisms convert inorganic carbon and water to potential fuels (e.g. fuel alcohols) and fuel precursors (e.g. biomass, starch, lipids). Although metabolically engineered microorganisms, programmed to redirect renewable carbon sources into desired fuel products, are contemplated as best choices to obtain high volumetric productivity and yield, however, native populations of anaerobic microorganisms are still considered the primary choice for the production of biogas and bioethanol. These anaerobic microorganisms responsible for different degradation pathways and their functions in anaerobic digesters are continuously being updated. In this review, we discuss the essential role of anaerobic microbes in biogas and bioethanol production via consolidated anaerobic process. Additionally, key enzymatic reactions and microbiota involved in the degradation steps and in the production pathways are specifically highlighted. We also discussed the challenges that still exist for biofuel production from native populations of anaerobic microorganisms and their possible solutions.
