Introduction Biodiesel production does not result in a lot of waste. However, depending on the process and feedstocks use, it can produce some wastewater, minerals, resins, solids strained out of used oil and glycerin. Often, waste is not an issue for large producers because they can invest in the equipment needed to recycle and reuse … Read More

Introduction Commercial-scale biodiesel producers have many constraints beyond those which small producers need to meet. Commercial producers must satisfy the expectations of owners and/or stockholders for profitability. They must make optimal use of capital and other resources. They also have to include the cost of labor because it comes from paid employees. Small-scale producers will … Read More

Biodiesel is a diesel fuel that is made by reacting vegetable oil (cooking oil) with other common chemicals. Biodiesel may be used in any diesel automotive engine in its pure form or blended with petroleum-based diesel. No modifications are required, and the result is a less-expensive, renewable, clean-burning fuel. Materials for Making Biodiesel 1 liter … Read More

INTRODUCTION 21st century has been facing many problems like energy sustainability, environmental problems and rising fuel prices. Conventional fuels are known for polluting air by emissions of sulfur dioxides, carbondioxides, particulate matter and other gases. This has resulted to increased research in alternate fuels and renewable source of energy .Moreover, energy consumption of the world … Read More

Biodiesel is an alternative fuel for diesel engines that is produced by chemically reacting a vegetable oil or animal fat with an alcohol such as methanol or ethanol. In words, the reaction is: Oil + alcohol → biodiesel + glycerin The photo shows a bottle of biodiesel and glycerin (also called glycerol). The biodiesel is … Read More

Biodiesel is an attractive alternative fuel for diesel engines.The feedstock for biodiesel production is usually vegetable oil, pure oil or waste cooking oil, or animal fats The most common way today to produce biodiesel is by transesterification of the oils with an alcohol in the presence of an alkaline catalyst. It is a low temperature … Read More

Introduction Biodiesel  is a liquid biofuel obtained by chemical processes from vegetable oils or animal fats and an alcohol that can be used in diesel engines, alone or blended with diesel oil. ASTM International (originally known as the American Society for Testing and Materials) defines biodiesel as a mixture of long-chain monoalkylic esters from fatty … Read More

Biodiesel has been produced commercially in Europe since 1992, and European countries account for more than 80% of global biodiesel consumption. Since 2006, biodiesel capacity has more than doubled and in 2013, EU countries produced 10,367,000 tonnes of biodiesel. Biodiesel markets are experiencing double digit growth in the United States and Asia, in particular India … Read More
