What biodiesel means?

Biodiesel is a renewable, biodegradable fuel manufactured domestically from vegetable oils, animal fats, or recycled restaurant grease. Like petroleum diesel, biodiesel is used to fuel compression-ignition engines.

What is another name for biodiesel?

Methyl esters is the chemical name for biodiesel and glycerin is used in a variety of products, including soap.

What is the structure of biodiesel?

A typical molecule of biodiesel looks like the structure below. Mostly it is a long chain of carbon atoms, with hydrogen atoms attached, and at one end is what we call an ester functional group (shown in blue).

What are the two forms of biodiesel?

The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology. The Bioenergy Technologies Office (BETO) is collaborating with industry to develop next-generation biofuels made from non-food (cellulosic and algae-based) resources.

Which biofuel is the most sustainable?

The life cycle aggregated sustainability index of three biofuel production pathways including wheat-, corn-, and cassava-based bioethanol production pathways was determined, and the cassava-based bioethanol production pathway with the sustainability index 0.4292 is the most sustainable, followed by corn- and wheat- …

How does biofuels affect the environment?

Regarding non-GHG environmental impacts, research suggests that production of biofuel feedstocks, particularly food crops like corn and soy, could increase water pollution from nutrients, pesticides, and sediment (NRC 2011). Increases in irrigation and ethanol refining could deplete aquifers (NRC 2011).
