Biodiesel Processor: How you can build yours right in your own backyard

July 13th, 2009

Biodiesel is a self-sustaining domestic and renewable resource that can power your diesel engine without any kind of engine conversion whatsoever. With gas prices soaring out of control and our economy crippled by our reliance on foreign oil companies, the popularity of biodiesel as an alternative fuel is quickly growing in the United States.

Biodiesel is not raw vegetable oil as some people mistakenly believe. It is actually created from natural vegetable oils and fats through a chemical process that converts the vegetable oil and fats into fatty acid methyl esters (FAME). This process is called transesterification. Biodiesel can be used on its own to power your diesel vehicle or it can be blended with petroleum diesel fuel.

The advantages of using biodiesel over petroleum include:

• It can be created fairly inexpensively using recycled cooking oil or other fat animal or plant fat
• It’s biodegradable and completely free of toxins so it’s great for the environment
• It is a sustainable and renewable resource found within our borders so it can limit our dependency on foreign oil
• It emits no greenhouse gases and toxins that cause acid rain

From Pumps to Your Own Backyard with your own biodiesel processor

The process of converting raw vegetable oil into biodiesel fuel occurs in what is simply called a biodiesel processor. There are many commercial providers of biodiesel fuel, but these can often be quite pricey because the demand for this product has not yet reached its peak. However, with the increase in popularity of biodiesel, it has sparked a plethora of home brewers worldwide who have taken the time to learn how to brew their own biodiesel fuel and no longer rely on oil companies to power their vehicles.

That feeling of independence is catching and there are many biodiesel brewers who not only brew their own fuel, but they have also created their own biodiesel processors as well. A biodiesel processor can literally be made with items you can find at your local hardware store. There are also many biodiesel processor kits available online. These can be quite pricey, however, starting around $3,500, so consider your costs before you decide to buy.

Of course, the money you will save by creating your own biodiesel will easily pay for itself over time. Consider that the average American family spent more than $3,000 in gas in 2008 alone according to the H&T Index. And that number is going to keep going up with the price of gas increasing on a day-by-day basis.

Now, there are essentially two kinds of biodiesel processors: Batch Processors and Continuous Flow Processors.

Continuous flow processors are not meant for small home brewers because they require an almost 24/7 operation schedule and have larger capacities for creating biodiesel that far exceed what a home brewer would need. The costs of these systems are also extremely high and not practical for the home brewer. Because of that, we won’t go into detail about the different kinds of continuous flow processors as these aren’t practical for an individual to use to home brew biodiesel.

Batch processors are most commonly used by small start ups and home brewers. That’s because it involves a fairly simple method of creating biodiesel. It includes a reaction tank where you mix your oil, alcohol, and catalyst.

There are several different kinds of batch processors available including several commercial made units that you can simply purchase online. These are obviously the most expensive and according to various users on the site www.journeytoforever.com, haven’t produced quality results that warrant the price. They have been known to even catch fire.

Batch processors can actually be built pretty inexpensively just by using parts and pieces around the house or items you can buy at the local store. The most famous example is the Appleseed processor, which is made simply by using a hot water heater as the reaction tank. The water heater can be something you purchase new or even just scavenged from the dump. You’ll need about $150 in plumbing and electrical supplies and about a day’s worth of work.

Another example of a batch processor is the GL Eco-System, which is a waterless biodiesel processor. Similar to the Appleseed design, this processor simply doesn’t require a separate wash system. Every step in the biodiesel production is done in that water tank.

The Foolproof Method processor requires no titration or pH meter. It uses a two-step system and a bottom-drained reaction tank, preferably a stainless steel drum. The first step creates a compound from acid and alcohol. The second step uses lye to form a water soluble salt that is removed during the wash.

Our final example of a batch processor is the Touchless Biodiesel Processor. This processor basically creates biodiesel by flicking a couple of switches and watching the process. It involves a water heater tank, a vacuum pump, and a mixing pump. It can be created using spare parts and household items. This processor takes a little more time to put together but can be worth it in the long run because of its almost automated process.

There are many different recipes to making your own biodiesel using chemicals and ingredients that are easily purchased locally and inexpensively such as lye and methanol, which is just stove oil. You can even recycle the used cooking oil from your local restaurant if you have a good relationship with the owner. Of course, anytime you’re handling chemicals, you should always use extreme caution. While none of the chemicals in biodiesel production are extremely toxic, the oil will be hot and can cause serious burns if not handled with care. We found video down to be fun and informative. It actually takes you through all the steps of making your own biodiesel. We found another helpful site with good step by step videos. You can visit this site (http://www.biodieselvideos.com/)

Creating your own biodiesel is not a hard process, but there is a lot to learn, so we don’t recommend just winging it. Before you begin making your own processor and biodiesel fuel, it’s best to have all the facts and get educated on the entire process first. Then, start off slow by making smaller batches. It will take some practice to get it right and you might have to go through a couple of batches before you get the hang of it. With the right guidance and by carefully following the prescribed process step by step you can easily start to brew biodiesel in your own backyard!

Biomass Energy: A Natural and Renewable Source of Clean Energy

June 8th, 2009

Green corn used for fuelBiomass energy is a renewable energy source that is produced by converting organic materials that come from plants and animals into energy such as electricity. We’ve been making good use of this source of energy ever since man discovered fire and used it to burn wood to heat his home and cook his meals.

Wood is still the most common form of biomass materials used today, although other examples include crops such as corn and sugar cane, manure, garbage, forestry residues like sawdust and wood chips, and many other types of plantlife. Even algae can be used as a biomass material to produce biomass energy 1!

How Biomass Energy Is Produced

Biomass materials, during their lifetime, absorb energy from the sun and carbon dioxide gases from the atmosphere in the process of photosynthesis. When it’s time for us to harness this power and create biomass energy, we release the solar energy that has been harvested by various methods including burning. The energy released is given off in the form of thermal energy and can be used to heat water and produce steam, which in turn can power a steam turbine to generate electricity.

The production of thermal energy isn’t the only method in which we create energy from biomass materials. Manure and rotting garbage from landfills can be used to harvest methane gases and the fermentation of crops like corn and sugar cane can be used to create liquid biofuel, which can be used to produce the transportation fuel known as ethanol 2.

The Use of Ethanol as a Fuel

Currently, ethanol has the highest volume of production of any biofuel today with more than 100 million barrels coming from corn grain each year. Ethanol is an alcohol fuel that can be made not just from corn, but also wheat, sorghum, potato skins, rice, sugar beets, and yard clippings.

Ethanol can be combined with gasoline to fuel cars, reducing the amount of oil we consume each year. This combination of gas and ethanol in your engine can often make your engine burn hotter and operate more efficiently. Any engine that can be powered by gasoline can use a combination of 90 percent gas and 10 percent ethanol, called E10. Some states, like Minnesota actually require the use of E10, because it helps reduce pollutants like carbon monoxide in the air. Special engines are required for liquid fuel that contains more than 10 percent ethanol 3.

Biomass Energy and Its Impact on the Environment

While it’s been argued that the burning of biomass materials releases carbon dioxide into the air, a known greenhouse gas, this argument doesn’t take into account the fact that the biomass materials only release the carbon dioxide that they had originally consumed. When we grow biomass materials, they naturally store the energy of the sun and consume carbon dioxide and release oxygen. That same amount of carbon dioxide the materials absorbed is then released back into the atmosphere once it is converted to energy.

Fossil fuels on the other hand release pollutants and carbon dioxide that was captured millions of years ago, essentially introducing “new” pollution in the air. Fossil fuels also release sulfur which is the main cause of acid rain.

And, unlike fossil fuels, biomass materials are truly a renewable and sustainable source of energy as long as we continue to replenish what we use in terms of replanting the materials we consume. Biomass crops are easy to grow, harvest, and replace without scarring the earth or depleting natural materials 4.

The Benefits of Biomass Energy to the Economy

When more than 60 percent of the petroleum we consume today is imported from other nations, biomass can have a significant impact on our economy 5. Biomass energy can effectively lessen our dependency on foreign oil imports and can reduce the price of gasoline when we use ethanol as a transportation fuel. With today’s resources and technology, we can effectively replace about 30 percent of our petroleum consumption with biomass 6.

Oil requires massive amounts of capital to explore and find new areas to drill. Ethanol is a reliable, constant source of fuel that can be grown right within our borders, without the harmful effects or consequences that arise from oil spills.

The production of ethanol also takes the money out of the hands of foreign oil giants and puts it into the hands of American farmers who desperately need to develop new ways to increase their revenue.  And while some may argue that the use of corn in the production of ethanol has been the major cause for the increase in prices of corn, because the supply was depleted, a recent study by the Agricultural and Food Policy Center of Texas A&M University sites evidence to the contrary.

The study states that the underlying force that is responsible for the increased price in corn and other agricultural commodities is the higher energy costs of oil. Higher energy costs translate to higher production costs for the agricultural industry. Rising fertilizer costs reduced the number of acres planted in 2006 – 2007 by more than 3 million! This reduction in acreage leaves the crops more vulnerable to natural disasters such as storms and can drive the price up significantly 7.

This chain of decreased production has hit the livestock market the hardest, since they have to purchase corn to feed their animals. However, recent advancements in ethanol production through a process called dry grind ethanol production can help offset these prices for livestock producers. In dry grind ethanol production, distiller’s grains are produced, which can be used to feed livestock. Distiller grains have a higher protein and energy content than corn and can help increase the daily weight gain of livestock.

It’s hard to deny the positive effects that developing biomass energy can have on our environment, our economy, and our energy production. In this slumped economy, removing our dependency from oil imports can stimulate the economy by increasing the rural development of the ethanol industry and creating new jobs for Americans. By substituting biomass energy for fossil fuels like coal and natural gas, we can help clean up the environment and create a renewable and sustainable source of energy that we can rely on for thousands of years.
