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 …

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 …

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 …

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 …

As embalagens biodegradáveis são uma das mais recentes alternativas que vêm despertando o interesse de pesquisadores brasileiros. As tradicionais embalagens de plásticos sintéticos, embora garantam a proteção desejada para diversos tipos de produtos, causam sérios problemas ao meio ambiente por não serem biodegradáveis. Na Unicamp, o assunto está sendo estudado …

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 …

The U.S. Environmental Protection Agency (EPA) has announced that an estimated one million pounds of household hazardous waste (HHW) has been collected in Louisiana in the aftermath of Hurricanes Katrina and Rita. HHW typically consists of cleaning products found in most homes as well as lawn and garden products, pesticides …

On November 1, 2005 in the African state of Botswana, the Waste Management Act and with the National Waste Management Strategy have been put in place for the promotion of human health, and environmental protection such as water, soil, air and biodiversity. They are also meant for the protection of …

Climate change is a hot topic these days with the federal government. Canada‘‘s target is to reduce the Greenhouse Gas emissions by 6% below the 1990 levels between 2008 and 2012. The parties involved in the Kyoto Protocol met on February 16th 2005 to put the Kyoto Protocol into force. …

A report, commissioned by Enhance, on London‘‘s market potential for biodiesel made from used cooking oils (UCO), has been released. The escalating prices of non-renewable fuels, the increasing demand for fuel in general and the effect these fuels have on the climate will coerce the need for biodiesel in London. …
