Comparative Review

Recent interest in alternative energy sources, particularly biofuels from biomass, is becoming increasingly evident due to energy security and environmental sustainability concerns, such as depletion of conventional energy reserves and carbon footprint effects, respectively. Existing fuels (e.g., biodiesel and ethanol) are neither sustainable nor cost-competitive. There is a need to integrate the recent advanced manufacturing approaches and machine intelligence (MI) techniques (e.g., machine learning and artificial intelligence), targeted on the midstream segment (i.e., pre-/post-conversion processes) of biomass-to-biofuel supply chains (B2BSC). Thus, a comparative review of the existing MI approaches developed in prior studies is performed herein. This review article, additionally, proposes an MI-based framework to enhance productivity and profitability of existing biofuel production processes through intelligent monitoring and control, optimization, and data-driven decision support tools. It is further concluded that a modernized conversion process utilizing MI techniques is essential to seamlessly capture process-level intricacies and enhance techno-economic resilience and socio-ecological integrity of B2BSC.

Insight Into

Major changes are occurring with far reaching implications for the existing equilibria or disequilibria in the water-energy-food-environment interface. The increased demand of energy worldwide will reflect directly and indirectly on water-dependent systems. Direct implications will come from higher energy prices, which make extraction and conveyance of water more costly. Indirect implications will be in the form of demand for alternative energy sources. It triggers demand for hydropower and remains a major driver—along with some environmental policies—for biofuel expansion. The key question is how these effects may alter water allocation and influence food security, rural poverty and environmental sustainability. This paper sets the background and context of this special issue by highlighting some of the major water-related policy issues related to the subject and provides an overview and synthesis of the papers in this special issue. Besides offering insight into how these papers address these questions in the practical context of few selected countries and basins, this paper also indicates some key areas for future research on the subject.

In the context of fossil fuel sources are gradually depleted, production and use of biofuels has become a popular trend in the world. In Vietnam, the development of biofuel production and use has been implemented since 2018. However, in order for this fuel to be widely used to contribute to environmental protection, there are still many obstacles.Among the alternative energy sources currently in use (wind, solar and nuclear energy), bioenergy is an inevitable development trend, especially in agricultural countries and imported. fuel, due to its benefits: production technology is not too complicated, utilizing local raw materials, increasing agricultural economic efficiency, without changing engine structure as well as lower facilities Existing floors and competitive prices compared to gasoline.Increasing the use of biofuels is not only about protecting the environment but also contributing to the positive transformation of the lives of people in remote areas of the country.

Global awareness of the energy crisis and the environmental impacts related to fossil fuels have driven the use of alternative energy sources such as biofuels. Nyamplung is one type of plant suitable for biofuel production. This study aims to determine perception and attitude community towards the development of nyamplung. The study was conducted in April - July 2018 in Patutrejo Village, Purworejo District, Central Java. Data collection was carried out by interviewing the community involved in the Self-Sufficient Village program in 2009, namely farmers, extension workers, officials in the Forestry Service Branch and officials in Perum Perhutani. The data obtained were tabulated and analyzed using a Likert Scale. The results showed that perceptions and attitudes of the community towards the development of nyamplung are as follows: First, nyamplung is suitable to be developed for environmental functions, namely as a windbreak, which protects agricultural land near the sea to remain productive; Second, nyamplung is not profitable to be developed for biofuel business because the price of nyamplung seeds is low and the processing of nyamplung seeds requires a modern machine; and Third, the development of nyamplung for biofuels does not have the support of the community. They are not willing to plant nyamplung on their own land, are not interested in processing nyamplung seeds for biofuel and are not interested in collecting and selling nyamplung seeds.

Brazil follows the global trend to seek viable alternative energy sources that can improve the quality and secure supply of energy with environmental sustainability, allied to the necessity of facilitating a fitting end to the sludge treatment plants sewage. The biomass present in SS is emerging as an alternative to the country's energy matrix, through the Low Temperature Conversion process – LTC of the sludge in the production of biofuel (biooil and coal). This article aims to characterize the coal obtained through the Low Temperature Conversion and evaluate the thermal behavior. In this study physical and chemical studies were made: elemental analysis (CHNO), calorific power, Thermogravimetry (TG) at a heating rate of 10°C min-1 under synthetic air atmosphere, and spectroscopic. The thermogravimetric study found a thermal stability at 300oC. In the spectroscopy in the infrared (IR) regionit was observed bands related to the presence of water, organic matter and silicon oxides in the SS samples analyzed.

The biofuels are the most important alternative energy sources in future to fulfil the energy demands. The team of our students carried out an innovative process to convert waste to value-added products. The students have been visited many meat stalls and gathered the required amount of resources with and without cost. The collected waste chicken skin and pig tallow is heated and extracted fat, which is the primary sources to produce the biofuel. The fat extraction process was carried by shredding down the waste chicken skin and pig tallow. The obtained fat was filtered and heated up to 110ºC to remove all the impurities, water suspensions, blood cells and pieces of bones. The process called transesterification process was carried out to convert obtained fat into biofuel with methyl alcohol and KOH as a catalyst. Transesterification process carted with fat before acid wash and after acid wash to examine the effect of FFA on biofuel yield. The quantity of biofuel yield has been observed to be 62 to 68% for fat from waste chicken skin and 82 to 83 % for fat from pig tallow. The derived fuel from fat from both resources is combined with conventional diesel fuel to check the different properties on a volume basis varied by 10% up to 40%. The essential properties such as viscosity, density, flashpoint, fire point and calorific values were determined, and results show that the fuel combination CB20 and PB20 meets the all requirements of ASTM standards to fix as an additive fuel to CI engines. The clear biofuel from both the fat expressed higher viscosity, density, flash and fire point with a lesser value of energy density
