Biodiesel

Biodiesel is a renewable biofuel formed by long-chain fatty acid methyl or ethyl esters. If the esters that compose the biodiesel are methylic, they are called FAME (Fatty acid methyl ester). It is obtained through the chemical reaction of methanol (or bioethanol) with vegetable oils (rape, sunflower, soy, palm, jatropha). It does not contain sulfur and, compared to oil-derived diesel, greenhouse gas emissions are reduced (including CO2), as well as carbon monoxide (CO) emissions and emissions of particles and other polluting products.

Advantages:

  • It is a cleaner source of fuel, renewable and for household use.
  • Reduces oil dependency
  • It can be used in all diesel engine vehicles, without requiring conversions, adjustments or special regulations in the vehicle engine.
  • Easy to produce and store.
  • It emits 40-80 % less greenhouse gases than fossil fuels.
  • It increases engine lubrication and the flash point, thus reducing the danger of explosions due to gas emissions.
  • It is biodegradable and non-toxic
  • Improves air quality in urban areas.
  • Does not pollute water.
  • Reduces waste production.

Biodiesel production creates new opportunities for sustainable rural development within the framework of a more market-oriented farming policy, since it promotes the development of energy crops and the creation of agribusiness, helping maintain employment and income levels in rural areas.
