“…However, a sensitivity analysis found it to be sustainable when the Jatropha seed yield is >7000 kg ha −1 year −1 . Further, the sensitivity analysis also suggested that small-scale Jatropha cultivation can be economically viable when NPV = $450 ha −1 and BCR = 4.16 when the loan is not charged interest [131]. A similar study conducted in Northeast India displayed positive returns on Jatropha plantations, making it an economically feasible venture for the farmers of that region.…”

“…Major costs associated with Jatropha cultivation include establishment costs (land purchase/lease, equipment, farm preparation, seedling, and planting), management costs (insect pest, disease, irrigation, and nutrient management), and harvest and post-harvest costs (harvest, peeling, seed preparation, transportation, and marketing). However, due to variations in factors associated with the manpower requirement and wage rate in various geographical locations, the economic viability of its cultivation solely depends on the input costs, seed yield, and market price [131]. Several studies (i.e., 37) conducted from 26 countries across the world evaluated the economic feasibility of Jatropha cultivation and found comparative results (i.e., 10 were positive, 11 were negative, and 16 showed neutral results).…”

Growing Jatropha (Jatropha curcas L.) as a Potential Second-Generation Biodiesel Feedstock

et al. 2021

Dwindling supplies of fossil fuels and their deleterious impacts on human health and the global environment have intensified the search for substitute energy sources. Biodiesel has been identified as a promising renewable energy substitute for diesel fuel due to several comparable and sustainable properties. However, approximately 95% of biodiesel is derived from edible oil crops, threatening the current food supplies. Therefore, the biodiesel production potential from inexpensive, non-edible, and non-conventional bioenergy crops, such as Jatropha (Jatropha curcas L.), has attracted the attention of many researchers, policymakers, and industries globally. Jatropha is considered to be the second-generation biofuel feedstocks for biodiesel production. However, sustainable biodiesel generation from J. curcas oil has not yet been attained, owing to different socio-economic, ecological, and technical factors. This study aimed to synthesize the information from the existing literature on the present status and to identify the knowledge gaps for future research on Jatropha by providing comprehensive information regarding its origin and distribution, morphology, phenology, and reproduction, genetic diversity, its productivity, oil content, and fatty acid composition, the methodology used for extracting biodiesel, and agronomic, economic, and environmental aspects of biodiesel production. The germplasm screening of J. curcas and the exploration of its adaptability and agronomic potential across diverse climates are highly desired to promote this crop as an alternative biofuel crop, particularly in arid and semi-arid regions. Moreover, future research should focus on developing, optimizing, and modernizing the technologies involving seed collection, the processing of seeds, oil extraction, and the production of biodiesel.

“…The high cetane number guarantees a low flash point. The oil contains a small amount of sulfur, resulting in lower SO2 emissions during combustion [17][18][19][20][21]. It is possible to obtain an oil yield higher than 1500 kg per hectare of this plant.…”

Using Biofuels for Highly Renewable Electricity Systems: A Case Study of the Jatropha curcas

2019

View full text Add to dashboard Cite

Recent movements for the decarbonization of the electricity sector have become a priority for many countries around the world and will inevitably lead to the sharp decline of fossil-fuel-based energy. Energy from fossil fuels is to be replaced by renewable energy sources (RES), although the transition will neither be cheap nor smooth. One sustainable and environmentally friendly alternative to fossil fuels and which will take a considerable share in the increasing supply of renewable energy resources is biofuels. There are various types of biofuels used in practice; however, biodiesels represent one of the most popular and widespread ones. This paper focuses as a case study on the byproducts of Jatropha curcas, a crop and a plant that is already used for biofuel production and which is subsequently employed in electricity generation in Jatropha curcas producing regions. This paper identifies the limitations and prospects of Jatropha curcas utilization. Also, Jatropha curcas is compared to other materials suitable for biomass generation. An economic analysis for a 2 MW biofuel powerplant was conducted incorporating various market-related risks. The study shows that at current prices, net profitability can be achieved using Jatropha curcas byproducts for producing electricity.

“…Local varieties of castor plant have been grown in the northeast of Brazil for biodiesel production, using the residues for making biogas and biofertilizers 8 . Biodiesel from jatropha and karanja, non-food trees with low nutrient requirements and minimum care, represents an opportunity for rural and semi-arid regions in South Asia 9 , sub-Saharan Africa 10 and India 11 . Local companies in the Mekong delta (Vietnam) plan to produce biofuel from catfish fat in large scale 12 .…”

Residues from the wine industry constitute an abundant feedstock for biodiesel production in wine-producing countries. The use of grapeseed oil, together with bioethanol obtained from distillation of wine surplus or grape skins and stalks and wine lees, as reagents in the transesterification reaction, results in a mixture of fatty acid ethyl esters (FAEE), which is a fully renewable, autochthonous, and waste-derived biofuel. In this work, a blend of FAEE produced from grape seed oil with diesel fuel was selected based on a study of fuel properties, and the optimal blend, with 30% v/v of FAEE, was tested in a Euro 6 engine following the Worldwide harmonized Light-duty Test Cycle (WLTC) and a Real Driving Emissions Cycle (RDE), as required in the new certification procedures. Engine performance and emissions from this blend and a commercial diesel fuel were compared. The FAEE blend showed a significant potential to reduce particle emissions, both in mass and number (from 23% in number to 46.5% in mass for WLTC, and from 56% in number to 61% in mass for RDE), and CO (25.5% for WLTC and 39% for RDE) but penalized NOx (32% higher in WLTC and 26.4% higher in RDE).
