Economic and Sustainability of Biodiesel Production—A Systematic Literature Review

2021

As Earth’s fossil energy resources are limited, there is a growing need for renewable resources such as biodiesel. That is the reason why the social, economic and environmental impacts of biofuels became an important research topic in the last decade. Depleted stocks of crude oil and the significant level of environmental pollution encourage researchers and professionals to seek and find solutions. The study aims to analyze the economic and sustainability issues of biodiesel production by a systematic literature review. During this process, 53 relevant studies were analyzed out of 13,069 identified articles. Every study agrees that there are several concerns about the first-generation technology; however, further generations cannot be price-competitive at this moment due to the immature technology and high production costs. However, there are promising alternatives, such as wastewater-based microalgae with up to 70% oil content, fat, oils and grease (FOG), when production cost is below 799 USD/gallon, and municipal solid waste-volatile fatty acids technology, where the raw material is free. Proper management of the co-products (mainly glycerol) is essential, especially at the currently low petroleum prices (0.29 USD/L), which can only be handled by the biorefineries. Sustainability is sometimes translated as cost efficiency, but the complex interpretation is becoming more common. Common elements of sustainability are environmental and social, as well as economic, issues.

“…The majority of studies that have addressed sustainability have focused on environmental issues, reporting data with respect to greenhouse gas emissions, energy balance, and production of a biodiesel energy unit. The variables have generally been evaluated utilizing Life-Cycle Assessment methodologies [7][8][9]14,15,[47][48][49][50][51].…”

“…On the other hand, previous studies have only addressed economic and social factors in marginal and isolated fashion. As regards economic issues, biodiesel production costs have been reported in a limit number of studies [7,14,48]. The social dimension of the use of Jatropha curcas has only been explored during its cultivation stage, which was found to be associated with job creation [13].…”

“…Six different indicators were established in order to evaluate the sustainability of each of the three scenarios on the basis of the environmental, economic, and social factors that have been most frequently reported in the literature [7,9,14,15,47,48], and in accordance with the information available vis-à-vis the production system. These indicators cover all three dimensions of sustainability and are evaluated for the entire life cycle of the production system for each of the scenarios included in this study.…”

Using information from an experimental planting of non-toxic Jatropha curcas (NTJC) with minimal water and fertilization resources on rural marginal soil the objective of this article is to determine the sustainability of this raw material for producing biodiesel and the possibilities for improving it through life-cycle assessment (LCA). Three production scenarios were studied: minimal resources (MR), which focuses on the obtaining of biodiesel; minimal resources and utilization of sub-products (MRUS), which includes the utilization of the residual products in order to produce food and solid biofuels, as well as biodiesel; and utilization of biofertilizers, flood irrigation, and sub-products (UBIS), which incorporates the use of bio-fertilizers and irrigation in the production system. This study includes the selection of six sustainability indicators, as well as indicators by means of LCA methodology Finally, a sustainability index (SI) for each scenario was determined on the basis of an index of environmental sustainability of energy products (IESEP). Our results indicated that the MR scenario yielded the lowest SI 0.673, while the MRUS scenario had the highest SI 0.956. It concludes that sustainability is greater when it utilizes minimal water and fertilization resources during the raw material production stage, and the residual products are used for food and energy products made possible by the non-toxic properties of Jatropha curcas.

“…Renewable biofuels derived from agricultural biomass are much needed as the global supply of fossil fuels is in crisis (Baral et al 2020). Among numerous biomass crops, Jatropha curcas (L.) represents a promising candidate, and therefore a lot of researches has been conducted to maximize its exploitation (Sidibe et al 2020).…”

Evaluation of indigenous fungal entomopathogens and aqueous leaf extract of Annona muricata against Polyphagotarsonemus latus infesting Jatropha curcas in Indonesia

Abstract. Puspitarini RD, Afandhi A, Fernando I. 2021. Evaluation of indigenous fungal entomopathogens and aqueous leaf extract of Annona muricata against Polyphagotarsonemus latus infesting Jatropha curcas in Indonesia. Biodiversitas 22: 2648-2655. The broad mite Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae) has been known to cause a great deal of injury on Jatropha curcas (L.) plantation in Indonesia. Isolation of indigenous fungal entomopathogens from rhizosphere soils, followed by pathogenicity assay was conducted to find an effective isolate for controlling P. latus. Additionally, the potential combination of the selected isolate and soursop (Annona muricata L.) aqueous leaf extract (SLE) was investigated. A total of 24 isolates were obtained by using the insect bait method. Four fungal isolates, namely Paecilomyces sp. 1., Lecanicillium sp., Beauveria sp., and Fusarium sp. 1, showed high conidial viability and were chosen as representatives to assess their pathogenicity against P. latus. Among the tested isolates, Beauveria sp. which had the highest conidial viability among the tested isolates, needed a shorter period to completely kill the tested mites. However, the compatibility test revealed the deleterious effect of SLE on Beauveria sp. SLE at all concentrations showed a very toxic effect on the fungus, therefore the two must be applied separately. Our results provide useful information on the effectiveness of indigenous entomopathogenic fungi Beauveria sp. and aqueous leaf extract of A. muricata as an alternative tool to control the broad mite P. latus on the J. curcas plantation.
