“…Jatropha oil is a non-edible vegetable oil possessing all good qualities of lubricant such as biodegradability, 22 safety for handling, higher flash and fire points compared to diesel, 23 better thermo-oxidative and hydrolytic stability compared to other vegetable oils 24 and comparable cost with mineral oil. 25 Further, Omayma El Kinawyet et al 26 based on their experimentation, have recommended Jatropha oil as lubricating oil to substitute low viscosity mineral oil. It was reported that Jatropha oil had performed better compared to soybean and sunflower oils for the same temperature range.…”

Lubricants play a major role in mechanical machines and studies on various nanolubricants are reported in the literature. This work deals with nanolubricants using blend of oils as base for nanolubricants. Nano-blended lubricants were prepared with a blend of ISO VG46 oil (mineral oil) and Jatropha oil (non-edible vegetable oil) and using them in proportions of 90:10 and 80:20 by dispersing 0.5–3 wt.% of surface-modified CuO nanoparticles by a two-step method. Various properties of these oils such as dispersion stability, viscosity and thermal conductivity were determined. Experimental values of viscosity were compared with the values predicted by using different viscosity models. Nano-blended lubricant 9010 was found more sensitive at lower concentration of nanoparticles compared to nano-blended lubricant 8020. It is observed that nano-blended lubricant 9010 with 1.5 wt.% CuO is more suitable for use in place of ISO VG46 oil compared to nano-blended lubricant 8020. Thermal conductivity values of all types of nano-blended lubricants have been found by thermal conductivity model to be approximately matching with the measured values.

“…Land has been reallocated in favor of Jatropha producers, often at the cost of the local people living on marginal lands. However, within a short period, it generated competition and conflict over resources, mainly land but also water and other resources on which impoverished people may depend (such as fuel wood for charcoal production), and failed to result in the expected benefits (Janssen 2009, Kumar et al 2012, Timko et al 2014.…”

Conflict over natural resources is a widespread phenomenon in the global south. Trends in consumption, demographics, environmental degradation, and socio-political dynamics are exerting significant pressure on the availability and accessibility of natural resources. In many countries, the governance of land for commercial agricultural investment leads to conflict. Such conflicts are complex, and the drivers extend beyond resource scarcity to issues of access and competition. This paper is based on the results of field research on investments in large-scale Jatropha plantations for biofuel production in Ethiopia. A case study of a large-scale Jatropha plantation in eastern-central Ethiopia is used to reconstruct the history of a short-lived, large-scale biofuel development in Ethiopia, and to examine the processes and the reasons for its failure. Between 2006 and 2009, more than 400,000 ha of land were acquired for industrial biofuel development. Given the country's dependence on imported fossil fuels and the global rush for alternative energy sources, the Ethiopian government, not surprisingly, gave emphasis to investment in biofuel development, mainly through Jatropha plantation. However, after costly experimentation, the "miracle crop" did not deliver what had been promised. Instead, it dispossessed and displaced thousands of marginalized local smallholder agropastoralists, created conflict over water and land resources, and kept thousands of hectares of land out of production. In the end, the rhetoric of "Jatropha revolution" and promises of local and national development were never materialized; the government's ambitious biofuel strategy also failed to achieve its objectives. The main argument of this paper is that the failure of large-scale biofuel companies to fulfill their ambitious promises in Ethiopia is part of the general failure in the governance of large-scale commercial agriculture and misleading views toward, and unrealistic promises of, Jatropha investments. These negatively affected the livelihood of the local agropastoralists and their interactions with the companies, which caused instabilities and conflicts in the area. It is hoped that the findings of this research will contribute to knowledge production and policies on the governance of large-scale commercial agriculture.

“…They mentioned that the cost of Jatropha oil and kerosene was estimated to be US$0.085/L and US$1.23/L, respectively, and the cost of biodiesel from jatropha oil and petroleum diesel was also estimated at US$0.99/L and US$1.21/L, respectively, in the year 2010. Sunil Kumar et al [23] did research on importance of Jatropha curcas for Indian economy and mentioned the price of locally generated biodiesel about Rs. 46.45/L without any taxation and it was comparable to retail selling price of petro-diesel in India (Rs.…”
