Continued use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Biodiesel derived from oil crops is a potential renewable and carbon neutral alternati...

Due to increasing energy demand and limited fossil fuels, renewable energy sources have gained in importance. Particulate matter (PM) in general, but also PM from the combustion of wood is known to exert adverse health effects in human. These are often related to specific toxic compounds adsorbed to the PM surface, such as polycyclic aromatic hydrocarbons (PAH), of which some are known human ca...

This research aims at developing anoperator training simulator (OTS) using AspenOTS Frameworkfor fatty acid methyl ester (FAME) production plant. All over the world, there is an increasing interest towards the use of vegetable oils in much desired ecofriendly biodiesel production. In view of environmental concerns due to high polluting nature of fossil fuels and also because of the limited avai...

Electric power generation system development is reviewed with special attention to plant efficiency. While higher efficiency is well understood to be economically beneficial because of fuel savings, its effect upon reduction of all plant emissions without installation of additional environmental equipment, is less well appreciated. As CO2 emission control is gaining increasing acceptance,effici...

Introduction In the last years there is a growing interest in the development and study of alternative fuels across various transport industries. Aviation industry is no exception to this trend. Indeed, the International Air Transport Association (IATA) established the importance of sustainable low-carbon alternative aviation drop-in fuels in their recent Technology Roadmap [1] in order to repl...

Background Mitigation of greenhouse gas emissions from transportation sources will require implementation of a variety of strategies, including improvements in the efficiency of overall vehicle/fuel systems, such as hybrid and new high-efficiency diesel engines, and use of synthetic fuels to replace or supplement petroleum-based fuels. A particularly attractive class of synthetic fuels is oxyge...

The preferential channeling of different fuels to fat and changes in the transcription profile of adipose tissue and skeletal muscle are poorly understood processes involved in the pathogenesis of obesity and insulin resistance. Carbohydrate and lipid metabolism may play relevant roles in this context. Freely moving lean Zucker rats received 3- and 24-h infusions of Intralipid (Pharmacia and Up...

Biomass fuels, charcoal and kerosene are the most used cooking fuels in Tanzania. Biomass fuel use has been linked to Acute Respiratory Infections (ARI) in children. It is not clear whether the use of charcoal and kerosene has health advantage over biomass fuels. In this study, the effects of biomass fuels, charcoal/kerosene on ARI in children under five years old in Tanzania are quantified and...

Amyris is a renewable products company providing sustainable alternatives to a broad range of petroleumsourced products. Amyris applies its industrial synthetic biology platform to convert plant sugars into a variety of molecules flexible building blocks that can be used in a wide range of products. Amyris’s initial portfolio of commercial products is based on Biofene, Amyris’s brand of farnese...

The benefits of using alternative fuels (AFs) in the cement industry include reduction of the use of non-renewable fossil fuels and lower emissions of greenhouse gases, since fossil fuels are replaced with materials that would otherwise be degraded or incinerated with corresponding emissions and final residues. Furthermore, the use of alternative fuels maximizes the recovery of energy. Seven di...
