“…Peanut oil methyl ester showed the second highest content of saturated fatty acid (with a small amount of long-chain saturated fatty acids, such as arachidic, docosanoic, and lignoceric acids). According to the existing literature [29], transesterification or purification would not change the fatty acid compositions. The results were consistent with the findings of other studies [30][31][32].…”

-Vegetable oil dielectrics have been used in transformers as green alternatives to mineral insulating oils for about twenty years, because of their advantages of non-toxic, biodegradability, and renewability. However, the viscosity of vegetable oils is more than 3 times of mineral oils, which means a poor heat dissipation capacity. To get low-viscosity dielectrics, transesterification and purification were performed to prepare vegetable oil methyl esters in this study. Electrical and physical properties were determined to investigate their potential as dielectrics. The results showed that the methyl ester products had good dielectric strengths, high water saturation and enough fire resistance. The viscosities (at 40℃) were 0.2 times less than FR3 fluid, and 0.7 times less than mineral oil, which indicated superior cooling capacity as we expected. With the assistance of 0.5 wt% pour point depressants, canola oil methyl ester exhibited the lowest pour point (-26℃) among the products which was lower than FR3 fluid (-21℃) and 25# mineral oil (-23℃). Thus, canola oil methyl ester was the best candidate as a low-viscosity vegetable oil-based dielectric. The low-viscosity fluid could extend the service life of transformers by its better cooling capacity compared with nature ester dielectrics.

“…Life-cycle analyses show that total greenhouse gas emissions and energy balance from these biofuels are considerably superior to equivalent fuels derived from fossil fuel sources (Fan et al, 2013). Pennycress oil also provides high-quality feedstocks for industrial lubricants (Cermak et al, 2013), and the seed meal remaining after oil extraction is high in protein, with potential use as a fodder supplement or a weed-suppressing horticultural biofumigant (Vaughn et al, 2005). Recent estimates of potential pennycress production in Midwest USA projected production of circa 4 billion US gallons on 16.2 million hectares (Fan et al, 2013).…”

Diversification of agroecological systems to enhance agrobiodiversity is likely to be critical to advancing environmental, economic, and social sustainability of agriculture. Temperate-zone agroecological systems that are currently organized for production of summer-annual crops can be diversified by integration of fallow-season and perennial crops. Integration of such crops can improve sustainability of these agroecological systems, with minimal interference with current agricultural production. Importantly, these crops can provide feedstocks for a wide range of new bio-products that are forming a new agricultural bioeconomy, potentially providing greatly increased economic incentives for diversification. However, while there are many fallow-season and perennial crops that might be used in such a "bioeconomic" strategy for diversification, most are not yet well adapted and highly-marketable. Efforts are underway to enhance adaptation and marketability of many such crops. Critically, these efforts require a strategic approach that addresses the inherent complexity of these projects. We outline a suitable approach, which we term "sustainable commercialization": a coordinated innovation process that integrates a new crop into the agriculture of a region, while intentionally addressing economic, environmental and social sustainability challenges via multi-stakeholder governance. This approach centers on a concerted effort to coordinate and govern innovation in three critical areas: germplasm development, multifunctional agroecosystem design and management, and development of end uses, supply chains, and markets. To exemplify the approach, we describe an ongoing effort to commercialize a new fallow-season crop, field pennycress (Thlaspi arvense L.).

Cermak et al (2013) had compared properties of new crop oils (lesquerella, field pennycress, meadowfoam and cuphea) with common commodity vegetable oils. They found out that all the oils had unique properties or characteristics that make them suitable for lubricant application.…”
