Recently, we have introduced a new bioeconomic indicator in order to avoid the difficulties in evaluating the process and technologies for sustainability. In this paper, we wish to improve this new indicator for the analysis of sustainability. Indeed, the indicator has been based on the exergy...

Due to the depletion of petroleum products and fatal emissions from the tailpipe of diesel engines it has become a need to seek for the alternative of petroleum products for long-term use. Currently, researchers and experts have come to the conclusion that biodiesel along with higher alcohols...

Span 80 and Tween 80 are biodegradable surfactants that can be added to blended fuels such as hydrated bioethanol-gasoline and methanol-gasoline. They increase the fuels' water tolerance and reduce their corrosive properties, without altering their fuel characteristics. For this study, a mixture...

This paper reviews and discusses the potential of papaya seed and stone fruit kernel biodiesels - the two sources of 2nd generation transport biodiesels in Australia. The challenges associated with biodiesel production and their possible solutions, particularly on feedstock selection, oil...

Molasses is a first-generation bioethanol feedstock that is a byproduct of sugar production. Molasses is a viscous fluid; consequently, when it serves as a substrate, it needs to be dissolved in water to obtain the appropriate conditions for the yeast. Therefore, the mixing process of molasses...

Hydrocarbon based conventional fuels are considered as fast depleting and harmful to the environment as they release poisonous chemicals to the atmosphere. Higher Alcohols and Biodiesel are the most promising alternative fuels widely researched due to their availability, ease of production and...

Synthetic fuels produced with renewable surplus electricity depict an interesting solution for the decarbonization of mobility and transportation applications which are not suited for electrification. With the objective to compare various synthetic fuels, an analysis of all the energy conversion...

This study examined the effect of degumming process on physicochemical and biodiesel properties of six non-conventional oils in Nigeria extracted from the seeds and flesh of Terminalia catappa (seed), Irvingia gabonesis (seed), Glycine max (seed), Persea americana(flesh), Tithonia diversifolia...

Fossil fuels as the main energy source of every country now predicted will be ended no more than 40 years. Therefore, alternative fuel such as biofuel has been developed by many countries including Indonesia. Indonesia as one of the highest populated country and has wide areas of agriculture,...

Transportation played a significant role in energy consumption and pollution subsequently. Caused by the intense growth of greenhouse gas emission, efficient and sustainable improvement of the transportation sector has elevated the concern in many nations including Malaysia. Bioethanol is an...
