Biodiesel and Its Impact on the Environment

Biodiesel has been getting its share of interest among people in the search for alternative fuels. The cost of oils has been steadily going up in the worldwide market and many think it is time to find alternative sources to tone down in some way the rising costs of using gas and other petroleum-derived fuels. One of the alternatives found to have promise is the production of biodiesel.

Biodiesel refers to a type of processed fuel that can be derived from biological sources. It can be readily used in diesel engine vehicles. This distinguishes it from the use of straight vegetable oils (SVO) or waste vegetable oils (WVO) as the chosen alternative which requires vehicles to have modified diesel engines installed in order to make use of such fuels.

What makes biodiesel also an ideal alternative is that it is biodegradable and non-toxic. Biodiesel also provides considerably fewer combustion emissions when compared to petroleum-based diesel fuel.

Since biodiesel can readily be used in current diesel engines without having to modify them, it has the potential to supplement the use of petroleum-based fuels as a primary energy source to fill up the need of the world’s transportation sector. And not only that, biodiesel holds the promise of being used as a cheaper alternative heating fuel for domestic and commercial boilers.

The Best Biodiesel Filter for You

The processing of biodiesel may require a number of biodiesel filters in order to ensure that the end product is of excellent quality. When you try to recycle waste vegetable or surplus corn oil and make them into biodiesel, you might need a biodiesel filter for your engine to make sure that contaminants can’t enter into the engine and damage it. Different biodiesel filters may be required for a number of different applications.

Biodiesel filters should have the following properties in order to work best in any given conditions:

1. High Temperature Properties. Almost any filter media can be used for water-based products. But in the case of filtering hot oils, resins and other high temperature products, a filter media that can withstand prolonged exposure to high temperatures is preferred. Biodiesel filters should be able to have excellent high temperature properties to be able to handle the filtration of biodiesel well enough.

2. Excellent Filtering. Biodiesel filters should be able to filter out the contaminants well enough in order to make a better grade product. All filters have a micron rating that determines the size of the particles that can be effectively captured by the filter media. A biodiesel filter having a 5 micron rating is preferred to provide excellent filtering properties.

How to Use Biomass Energy?

There are many different ways to use biomass energy. Today, we are going to look at four different categories: biofuels, biopower, bioproducts, and space heating and cooling.

Biofuels

The two most common types of biofuels are ethanol and biodiesel. The most familiarly used form of ethanol is made from the starch in corn grain, and it is added into petroleum-based fuels to reduce toxic air emissions and increase octane. It is also available as an alternative fuel known as E-85. This type of fuel contains 83% ethanol during the summer and 70% in the winter.

Biodiesel, on the other hand, is made from soybean oil. Though not as popular as its ethanol counterpart, it has significant benefits to air quality. Biodiesel is usually mixed at 20% with petroleum diesel, and it is called B-20. The same process that is used to create biofuels can also be used to create antifreeze, plastics, glues, artificial sweeteners and toothpaste gels.

Biopower/Biopower

The only renewable electrical generation that is used more than biopower is hydropower. Biomass is created using direct combustion using conventional boilers that burn waste wood products. Steam is produced by this combustion, which, in turn, spins a turbine, activating a generator that creates electricity.

When biomass is turned to gas prior to this combustion, toxic materials are removed from the process. These systems are useful for powering isolated communities with electricity. There are significant amounts of biomass resources in the eastern half of the United States.

Bioproducts

Bioproducts are products that can be made from fossil fuels. These products general require a reduced amount of energy to create than petroleum-based products. If oxygen is present when heating biomass, more of the two gases produced. This process is called biosynthesis, and it can be utilized to create plastics and acids. These, in turn, can be used to create photographic films, textiles, and synthetic fabrics.

On the other hand, when biomass is heated without oxygen, pyrolysis oil is formed and phenol can be extracted from this formation. Wood adhesives, molded plastics, and foam insulation can then be created from phenol.
