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

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.

Advantages And Disadvantages

In recent years, the development of renewable energy alternatives to traditional fossil fuels has become one of the major challenges all over the world, due to the decline of fossil fuel reserves and their effect on global warming. Biodiesel has become a popular alternative energy source to reduce gas emissions compared to traditional fossil fuels. According to statistics, a nine-fold increase in global biofuel production between 2000 and 2020 was observed. However, its production generates a large amount of glycerol as a by-product, posing an environmental problem when disposed directly in landfills or by incineration. Therefore, low-value glycerol should be converted into high value-added derivatives. As glycerol carbonate is one of the most important derivatives of glycerol, this review aims to discuss the studies over the last ten years about glycerol carbonate synthetic methods, including the typical routes such as phosgene, esterification reaction, urea, oxidative and direct carbonylation as well as several rare synthetic procedures. At the same time, it summarizes the different catalytic reaction systems of each route comparing the advantages and disadvantages of various catalysts and evaluating their catalytic activity. Finally, the future development of glycerol carbonate synthesis is prospected from the point of view of development, technology research and industrialization.

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.

Research background: One of the global problems of modern transport is the harmful impact on the environment due to the use of carbon fuels. This is especially true in the context of the globalization of the economy and en-vironmental problems. The world has long been in the process of switching to alternative energy sources and reducing the use of fossil fuels. Adminis-trative measures and taxation of CO2 emissions are applied. Purpose of the article: The purpose of the article is to conduct a literary review in peer-reviewed publications on the problem of transport taxes and to make proposals for the introduction of an environmental tax within the framework of the classification of taxes proposed by the author for the pur-pose of their introduction. This analysis showed the predominance of publi-cations with an environmental aspect. Basically, the authors analyze the application of taxes on CO2 emissions, as well as various methods (logistical, technological, managerial) to reduce these emissions and improve the efficiency of transport systems. The main object of research is road transport, to a lesser extent - air transport and sea transport. Methods: The system approach, methods of scientific abstraction, formal logic, dialectical-theoretical methods, the method of empirical analysis, and other economic methods were mainly used in obtaining research results. Findings & Value added: The article deals with the modern problems of calculating and paying the transport tax, its role in the costs of transport organizations. The transport tax in Russia is likely to be replaced by an en-vironmental tax. The variants of introducing the “ecological” component in the transport tax used in Singapura are proposed. The classification of taxes proposed by the author for the purpose of their introduction can also serve the purpose of preserving the environment.

The evaluation and process risk assessment of (a) lignin precipitation from black liquor, and (b) the near-neutral hemicellulose pre-extraction for recovery boiler debottlenecking in an existing pulp mill is presented in Part I of this paper, which was published in the July 2012 issue of TAPPI Journal. In Part II, the economic assessment of the two biorefinery process options is presented and interpreted. A mill process model was developed using WinGEMS software and used for calculating the mass and energy balances. Investment costs, operating costs, and profitability of the two biorefinery options have been calculated using standard cost estimation methods. The results show that the two biorefinery options are profitable for the case study mill and effective at process debottlenecking. The after-tax internal rate of return (IRR) of the lignin precipitation process option was estimated to be 95%, while that of the hemicellulose pre-extraction process option was 28%. Sensitivity analysis showed that the after tax-IRR of the lignin precipitation process remains higher than that of the hemicellulose pre-extraction process option, for all changes in the selected sensitivity parameters. If we consider the after-tax IRR, as well as capital cost, as selection criteria, the results show that for the case study mill, the lignin precipitation process is more promising than the near-neutral hemicellulose pre-extraction process. However, the comparison between the two biorefinery options should include long-term evaluation criteria. The potential of high value-added products that could be produced from lignin in the case of the lignin precipitation process, or from ethanol and acetic acid in the case of the hemicellulose pre-extraction process, should also be considered in the selection of the most promising process option.
