Biodiesel runs in any unmodified diesel engine. There is no “engine conversion” typical of other alternative fuels. The diesel engine can run on biodiesel because it operates on the principle of compression ignition whereby air is compressed and then fuel is sprayed into the ultra-hot, ultra-pressured combustion chamber. Unlike gasoline …

1) Biodiesel runs in any conventional, unmodified diesel engine. No engine modifications are necessary to use biodiesel and there is no “engine conversion.” In other words, “you just pour it into the fuel tank.” 2) Biodiesel can be stored anywhere that petroleum diesel fuel is stored. All diesel fueling infrastructure …

Overall biodiesel emissions are lower than gasoline or diesel fuel emissions (with the exception of NOx, which we discuss on the next page). Compared to diesel, biodiesel produces no sulfur, no net carbon dioxide, up to 20 times less carbon monoxide and more free oxygen. Biodiesel has the following emissions …

The process of converting vegetable oil into biodiesel fuel is called transesterification and is luckily less complex than it sounds. Chemically, transesterification means taking a triglyceride molecule, or a complex fatty acid, neutralizing the free fatty acids, removing the glycerin, and creating an alcohol ester. This is accomplished by mixing …

Biodiesel production in Europe Not only in the US but also in Europe is biodiesel is becoming increasingly popular as an alternative to mineral oil-based fuel. In Europe around 50 manufacturers produce approximately 1.5 million tonnes of biodiesel, with a total capacity of around 2.1 million tonnes Germany is the …

A groundbreaking trial, collecting organic waste from householders in the London Borough of Bexley using aerobic bins, is set to revolutionise collections across the UK. A study, funded by SITA Environmental Trust has been published. "If you can eat it and it grows, it goes in the aerobic bin" was …
