Jatropha Oil Comment Date Correction
On October 19, 2015 the Federal Registerpublished a correction to the due date for comments for the Notice of Opportunity To Comment on an Analysis of the Greenhouse Gas Emissions Attributable to Production and Transport of Jatropha Curcas Oil for Use in Biofuel Production. The October 15, 2015, Biobased and Renewable Products Update included the article EPA Issues Draft GHG Analysis For ...

Effect of the solid content on biogas production from Jatropha curcas seed cake
Anaerobic conversion of Jatropha curcas seed cake was studied in a fivelitre working volume batch reactor at 30°C. Over a 60day operating period, a slurry of seed cake in water at a 1 : 20 seed caketowater ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The ...

Investigation on cross-compatibility barriers in the Biofuel Crop Jatropha Curcas L. With wild Jatropha species
Interspecific hybridization in Jatropha species plays a significant role in crop improvement by transferring useful traits such as yield, high oil content, maximum number of seeds, more femaleness, and hard stems for promoting Jatropha as a biofuel crop. The wide crosses among the species resulted in limited success due to pollen incompatability. Hence, the objective of the study was to assess ...

Statistical evaluation of the early-stage development of Jatropha energy plantations in Northeastern Mexico
A systematic evaluation of agricultural factors affecting the adaptation of the tropical oil plant Jatropha curcas L. to the semi-arid subtropical climate in Northeastern Mexico has been conducted. The factors studied include plant density and topology, as well as fungi and virus abundances. A multiple regression analysis shows that total fruit production can be well predicted by the area per ...

A comparative study of molar ratio effect on transesterification of Jatropha Curcas using kinetic and fuzzy techniques
Biodiesel is a biodegradable source of fuel that can be synthesised from edible, non-edible and waste oils through transesterification process. In this paper, we presented transesterification reaction of Jatropha Curcas oil by using sodium hydroxide catalyst at 150°C in batch reactor. Further, we designed the fuzzy model of the molar ratio and the performance evaluated by comparing fuzzy model ...

Biodiesel production from crude oil of Jatropha curcas and Pongamia pinnata by transesterification process
The present study is aimed to produce biodiesel from non-edible oil sources such as crude oil of Jatropha curcas and Pongamia pinnata by transesterification process which can occur at different temperatures (45°C to 70°C), depending on the oil used. For the transesterification of J. curcas oil (methanol 15% of oil and 12 g NaOH/litre), the reaction was studied with different temperatures. It was ...

Study on the Expansion Plan of Bio-Diesel for Transportation in Asia-Pacific Region
This project will involve a study of biodiesel production using the conventional raw materials such as Jatropha, in recognition of Partner Country concerns over the need for a stable supply of rapeseed and soybean oils for conventional biodiesel. This project will seek to address the gap in infrastructure for biodiesel use and distribution existing among the Partner countries. Korea will lead on ...

Eco–efficiency from cradle to grave design system based on atmospheric conditions in the biodiesel manufacturing sector produced from Jatropha curcas for sustainable cleaner production
Environmental impacts associated with the use of fossil fuels and their potential limitations in supply are driving the development and use of biofuels. A customised framework for eco–efficiency in biodiesel processing sector was considered. The major concepts, definitions, framework assessment, cradle to grave inventory of eco–efficiency are also considered. The paper also gives a ...

Greenhouse impact of fossil, forest residues and jatropha diesel: a static and dynamic assessment
Biofuels have been recognised as one option for mitigating climate change. However, in order to show the sustainability of biomass-based fuels, an assessment of the savings in Greenhouse Gas (GHG) emissions compared to fossil fuels needs to be clearly shown. There are two ways to measure the greenhouse impact of an activity. It can be done statically or dynamically, by using Global Warming ...

Biofuel scenarios in a water perspective: The global blue and green water footprint of road transport in 2030
Concerns over energy security and climate change stimulate developments towards renewable energy. Transport is expected to switch from fossil fuel use to the use of fuel mixtures with a larger fraction of biofuels, e.g. bio-ethanol and biodiesel. Growing biomass for biofuels requires water, a scarce resource. Existing scenarios on freshwater use usually consider changes in food and livestock ...
