CT: Biodiesel is a domestically produced, renewable fuel that can be manufactured from vegetable oils, animal fats, or recycled restaurant grease. It is a cleaner-burning replacement for petroleum diesel fuel. It is nontoxic and biodegradable.

N: 1. also bio-diesel, 1992, from bio- + diesel.
bio (prefix): word-forming element, from Greek bio-, comb. form of bios “one’s life, course or way of living, lifetime” (as opposed to zoe “animal life, organic life”), from PIE root gweie- “to live”.
The correct usage is that indicated in the biography, but in modern science it has been extended to mean “organic life.”
diesel (adj): 1894, named for Rudolf Diesel (1858-1913), German mechanical engineer who designed this type of engine.

2. Biodiesel is a liquid fuel often referred to as B100 or neat biodiesel in its pure, unblended form. Like petroleum diesel, biodiesel is used to fuel compression-ignition engines, which run on petroleum diesel.

3. How well biodiesel performs in cold weather depends on the blend of biodiesel. The smaller the percentage of biodiesel in the blend, the better it performs in cold temperatures. Regular No. 2 diesel and B5 perform about the same in cold weather. Both biodiesel and No. 2 diesel have some compounds that crystallize in very cold temperatures. In winter weather, manufacturers combat crystallization in No. 2 diesel by adding a cold flow improver. For the best cold weather performance, drivers should use B20 made with No. 2 diesel manufactured for cold weather.

4. In the United States, the term biodiesel is more restrictive, referring only to “the monoalkyl esters of long chain fatty acids”.

5. Biodiesel: term recommended by the Terminology Committee and standardized by the Validation Committee of the Sustainable Mobility Glossary.
