Fresh and Clean Made from Bean


What is it?

Biodiesel is a clean burning renewable fuel. It is made through a chemical process that converts the oils and fats into fatty acid methyl esters (FAME). it is intended to be a replacement for petroleum diesel fuel. Biodiesel is a biodegradable, nontoxic fuel that reduces emissions.

Materials Needed

Biodiesel is made of natural vegetable oils and fats. It is mostly made of soybeans in the U.S. The first step of converting the oils and fats into Biodiesel is esterification. In this stage the oil is mixed with sulfuric acid and methanol. The next stage is transertification, a catalyst such as Lye or Caustic Potash is added to the mixture. After this is the Settling Period where it settles for several hours an the glycerin settles to the bottom. Lastly, the Biodiesel is "washed" with water. The water picks up contaminants that settle at the bottom.

Cost and Maintenance

In the U.S 11.3 million dollars would be needed to build the facilities. The price of feedstock is $0.24 per pound and it accounts for 88% of the production cost . The Biodiesel would be $2.00 per gallon.

Modifications would need to be made to regular engines to prevent damage from the impurities. Regular engines could also use bioethanol. To prevent sludge regularly change fuel filters and have the fuel tank pressure cleaned by a shop. Algae could grow in the fuel tank and fuel lines. To prevent this add algicides to the fuel tank. Keep the fuel level topped off to prevent water build-up.

  • Require large amounts of fossil fuels through the use of fertilizers and harvesting

  • Water pollution from runoff

  • Increased erosion and loss of topsoil, loss of biodiversity, changing native habitats to monoculture crops, and harmful to ecosystems from pesticides and herbicides

  • Biodiesel can gel in colder weather

  • 2.8 billion acres to produce enough to convert biodiesel for all of our transportation needs, now 302 million acres

  • Each car would need 10 acres, 5 times more land to produce the equivalent of biofuel energy

  • Biodiesel can clog filters during the release of deposits that attached to tank and pipe walls from previous diesel use

  • Crushing the soybeans to make soybean oil uses energy and produces pollution
