biodiesel what is it

Biodiesel processor? Biodiesel is recently developed type of biofuel, made of replaceable staple. It is very similar to conventional diesel, used in motor vehicles, but it is not extracted from under the ground. Alternatively it is produced from vegetables, nuts and seeds. Main cultures used for biodiesel production are peanuts, sunflower, rape seeds, and soybeans. Literately, any vegetable oil can be used for biodiesel production. Also it can be made from industrial oils, such as restaurant grease. Number of scientific institutions comprehensively checked biodiesel in motor vehicles. And as tests reveal  biodiesel is less pollutive than normal diesel and performs almost as good. There is only slight difference in range of 3-5 percent (what distance a car can go on a certain amount of fuel). There is no need for engine alterations, so it can be used in any diesel powered machinery, pure, or as a mixture with petroleum diesel. Biodiesel can also be used in number of other appliances and equipment.

1. Low-Impact Living Initiative (LILI) is a non-profit organization whose mission is to help people reduce their impact on the environment, concerned only about recycling domestic and restaurant grease. As they say in their statement: It is very bed concept, to extend agricultural land to produce staple for biodiesel, while there is significant shortage of food in the world. Some producers of biodiesel, now using palm oil from enormous farming estates in West Africa or SE Asia. We believe that biodiesel made from this staple is even more harmful to nature than conventional diesel, and evidently more so. For more details, please visit Biofuel Watch web site.

2. This surely does not mean that we are supporting substitution of petroleum diesel by biodiesel for the entire fleet of cars, lorries and boats in the world, as there is not enough domestic and industrial grease to satisfy the demand. But this is certainly can be done locally. It is obvious that we need to limit the use of fuel, design more economical engines, share cars with colleagues to go to work, use buses and coaches more often, spend vacations at home, and work from own houses.
3. Climate change: biggest cause of greenhouse effect is the increasing level of carbon dioxide in the air, which allows shortwave length ultraviolet sun rays to reach the Earth surface, but prevents it from reflecting back to the space. Greenhouse gas (CO2) is the main component of exhaust gases produced by diesel and petrol engines. Using biodiesel as a fuel also produces carbon dioxide, but because biodiesel is produced from plants which use CO2 to grow, impact on environment is considerably lower.

4. Emissions: burning biodiesel produces fewer quantities of other harmful chemicals for example CO (carbon monoxide), particulate matters and alkanes. Level of N2O may be the same or higher, but is significantly cut down by catalytic converter and changes to ignition timing. Along with evidential benefits to the environment, it also reduces health risk for those who are frequently exposed to exhaust gases, due to the nature of their profession: road workers, waste collectors and others. Biodiesel exhaust odour is better than conventional diesel and it extends engine life, because of its lubricating properties.

5. Waste reduction: Biodiesel can be produced from used cooking oil. It is estimated that over 100000 tonnes of restaurant grease produced in the United Kingdom every year.

6. Spills: Because there is no need to ship crude oil from overseas, the possibility of leakage is eliminated. Leakages from cars and lorries are safe due to biodegradable nature of the fuel.

7. Energy balance: for every part of energy needed to create biodiesel, 3 parts of energy are created. While conventional diesel ratio is 1:1.

8. What can be done? Biodiesel can be bought, or produced at home. Biodiesel production equipment can be purchased jointly with neighbors or friends to satisfy the need of a few households. It is advised to use pure biodiesel on summer and half biodiesel half conventional mix during winter month. It is necessarily to change cars fuel filter after 500 or 1000 miles of running on biodiesel, because it can dissolve sediment from the tank. However if you always use biodiesel, fuel filter will last as normal.

9. Where to buy? Now, biodiesel available only at limited numbers of petrol stations. But it can be bought and delivered in special tanks, called IBCs.

10. Producing biodiesel: biodiesel can be produced at home. Staple for it could be restaurant grease, which is easily obtainable from local businesses for a little or no charge. Other components required for production are not difficult to get hold of. Ready-made biodiesel equipment is quite expensive, but with a bit of DIY skills it is possible to make a processor yourself using two oil barrels, couple of pipes, a pump, and some fittings. To make biodiesel, oil supposed to be put together with Sodium or Potassium Hydroxide (catalysts) and Isopropyl alcohol. After a certain period of time (usually about 8 hours) glycerin gets separated from the blend and settles at the bottom of a barrel. It can be used for various purposes, for example soap making. Biodiesel forms the layer at the top of a barrel. It is important to separate biodiesel from solid particles and water. Producers of biodiesel responsible for duty payments to HM Revenue and Customs. To increase the level of production, UK government lowered taxes by 20 pence per litter in 2002. In June 2007, tax was lifted completely for domestic producers (2500 or less litters annually). There was also change to number of returns that medium-sized companies shall send to HM Revenue and Customs yearly, from twelve to four.

11. Because of dangerous nature of chemicals needed to make biodiesel, it is necessarily to follow strict Health and Safety rules.

12. It is possible to buy biodiesel production equipment, as well as to make it yourself. Currently, there are courses available from LILI, which cover all stages of biodiesel production.

13. Sodium and Potassium Hydroxide as well as Isopropyl alcohol, which needed to produce biodiesel, can be purchased from Trinity Research. This company also collects unwanted glycerin free of charge.
