“…However, most of these resources have having a high free fatty acid contents which require the specified two steps method (first esterification and then transesterification) because high free fatty acid contents are not suitable for transesterification, unless, their free fatty acid contents is reduced to <1%, which compares to 1 mg KOH/g of potassium hydroxide. While, the maximum amount of alkaline catalyst cause the form of soaps; henceforth, diminishing the biodiesel yield (Živković and Veljković, 2018).…”

This study is reporting the biofuel synthesis and characterization from the novel nonedible feedstock cocklebur seeds oil. The Cocklebur crop seeds oil was studied as a potential source for biofuel production based on the chemical, structural and fuel properties analysis. The oil expression and FFAs content in cocklebur crop was reported 37.2% and 0.47 gram KOH/g, using soxhlet apparatus and acid base titration method, respectively. The maximum conversion and yield of the cocklebur crop seeds non-edible oil to biofuel was pursued 93.33%, using transesterification process. The optimum protocol for maximum conversion yield was adjusted: 1:7 oil-methanol molar ratios, ZnO nano-particle concentration 0.2 gm (w/w), reaction temperature 60 • C, and reaction time 45 min, respectively. ZnO nano-particle was prepared by a modified sol-gel method, using gelatin and the particle was XRD, TEM, XPS, and UV-vis spectroscopies. Qualitatively, the cocklebur crop synthesized biofuel was quantified and structurally characterized by GC/MS, FT-IR, NMR, and AAS spectroscopies. Quantitatively, the fuel properties of cocklebur crop biofuel was analyzed and compared with the international ASTM and EN standards.

“…The use of corn oil biodiesel reduces the emission of GHG, sulfur, particulate matters, and hydrocarbons [24], consequently lowering the negative impacts on air, water, land, biodiversity, and climate changes. Based on different approaches taking into account the emissions of the six climate gases defined in the Kyoto Protocol, it was estimated that biodiesel reduces the GHG emissions by 22-59 %, compared to fossil diesel [25] The use of biodiesel reduces life-cycle CO2 emissions by 50-75% or net CO2 emissions by 78.45% compared to fossil diesel [26]. Therefore, biodiesel is considered as a carbon neutral fuel, as plant during photosynthesis captured nearly overall CO 2 released during biodiesel production and use.…”

“…Also, the biodiesel burns with a significantly lower CO emission (up to 20%) compared to fossil diesel due to higher oxygen content and improved biodiesel combustion. Although the importance of biodiesel on the reduction of life-cycle CH 4 emissions is low (the most 2.57%), it is significant because CH 4 is a particularly harmful GHG [26]. Compared to fossil diesel, NO x emissions from the biodiesel burning are higher and generally influenced by the engine performances.…”

The present paper reviews the environmental aspects of the production and use of corn oil-based biodiesel. The environmental aspects are analyzed by considering the used-corn oily feedstocks and production technology. Besides that, the possibilities for the improvement of the biodiesel production process are emphasized. The most valuable corn-oil feedstocks are waste corn oil and corn distillers oil obtained primarily from dried distillers grains with solubles (DDGS). The use of DDGS, a by-product of ethanol production, for biodiesel production and glycerol, a by-product of biodiesel production, as a substrate for ethanol production, allows the development of an integrated ethanol/biodiesel production and contributes to the elimination or minimization of wastes and the production of the added-value products. Biodiesel is a degradable, less-toxic, safe, and generally, clean-burning fuel with exception of NOx emission that can be reduced by the appropriate methods but further investigations are desirable. Key words: corn oil, biodiesel, environmental aspect, ghd emission, pollution

Fuels and their components accumulate in soil, and many soil organisms are exposed to this pollution. Compared to intensive research on the effect of conventional fuel on soil, very few studies have been conducted on soil ecotoxicity of biofuels. Considering the limited information available, the present study evaluated the changes caused by the presence of biodiesel and diesel fuel in soil. The reaction of higher plants and soil organisms (microbial communities and invertebrates) was analysed. Conventional diesel oil and two types of biodiesel (commercial and laboratory-made) were introduced into the soil. Two levels of contamination were applied—5 and 15% (w/w per dry matter of soil). The plate method was used to enumerate microorganisms from soil contaminated with biodiesel and diesel fuel. Phytotoxicity tests were conducted by a 3-day bioassay based on the seed germination and root growth of higher plant species (Sorghum saccharatum and Sinapis alba). Fourteen-day ecotoxicity tests on earthworm were performed using Eisenia fetida. Based on the results of the conducted tests it was found out that the organisms reacted to the presence of fuels in a diverse manner. As to the microorganisms, both the growth and reduction of their number were noted. The reaction depended on the group of microorganisms, type of fuel and dose of contamination. The lipolytic and amylolytic microorganisms as well as Pseudomonas fluorescens bacteria were particularly sensitive to the presence of fuels, especially biodiesel. Fuels, even at a high dose, stimulated the growth of fungi. Monocotyledonous sugar sorghum plants were more sensitive to the presence of fuels than dicotyledonous white mustard. There was also a significant negative impact of contamination level on plant growth and development. Biodiesel, to a greater extent than conventional fuel, adversely affected the survival and volume of earthworms.
