Life cycle assessment and life cycle cost analysis of Jatropha
In this study, a Life Cycle Cost (LCC) is integrated within a life cycle assessment (LCA) model to comprehensively evaluate the energy, environment, and economic impacts of the Jatropha biodiesel production in China. The total energy consumption of producing 1 ton of Jatropha biodiesel is 17566.16 MJ, in which fertilizer utilization and methanol production consume 78.14% and 18.65% of the

Pretreatment Methods in Biodiesel Production Processes
The decomposed oil loses fatty acids which become detached FFAs, or ¡°used¡± oil and therefore less expensive feedstock to purchase. In order to increase the overall yield of biodiesel, the high-FFAs oil requires pretreatment processing that means subjecting the oil to acidic conditions, where the FFAs are converted to fatty acid esters and thereby lowered pH to acceptable values in the oil

Frontiers - Intensified biodiesel production from waste cooking oil
In this paper, the transesterification reaction of waste cooking oil (WCO) with methanol using KOH as catalyst to produce biodiesel was performed in a micro-reactor (1 mm ID) using a cross-flow inlet configuration. The effects of different variables such as, methanol-to-oil molar ratio, temperature, catalyst concentration, and residence time on biodiesel yield, as well as the associated flow

Biodiesel synthesis from neem oil using neem seeds residue
The main objective of the current reach work is to utilize the waste neem seed powder post-oil extraction for catalyst synthesis and use it for biodiesel production. The powdered carbon material is further modified by impregna-tion of KOH by 0.5 to 2.5 wt% and characterized by vari-ous techniques (SEM, EDS, and BET).

Moringa oleifera Seeds and Oil: Characteristics and Uses for Human
Indeed, Moringa oil could be a good substitute for olive oil in the diet as well as for non-food applications, like biodiesel, cosmetics, and a lubricant for fine machinery. Moreover, after oil extraction, the seed cake can be used in waste water treatment as a natural coagulant [ 4 ] or as an organic fertilizer to improve agricultural productivity [ 5 ].

Biodiesel production in Ethiopia: Current status and future prospects
Over 95% of global biodiesel production is accounted for by edible oils such as rapeseed (84%), sunflower oil (13%), palm oil (1%), soybean oil, and so on (2%) [44, 45]. However, their use causes a food-versus-fuel crisis, and significant environmental issues like deforestation, serious soil resource loss, and using the majority of pastoralist land.

Current trends in biodiesel production technologies and future
Algal oil for biodiesel stands as the preeminent selection of researchers as algae produce greater oil yield per area of arable land, provides opportunity for enhanced strain improvement, and the ability to augment the efficacy by co-products (Narula et al., 2017). Algae can engender 200 times more oil than potential plant oils.
