First generation biofuel is made from food crops or feed stocks that can also be consumed as human food by extracting the oils through fermentation. Crops like wheat, sugarcane, corn, sugar beet and sorghum are some of the main sources of producing biofuel. Since their availability and extraction through conventional means they are termed as conventional biofuels. Most common first generation biofuel includes:- (1) Biodiesel. Extracted from vegetable oils, animal fats, seeds from plants like Soybeans, Canola, and Sunflower are few of the examples.
It is also having the relation with bio-fuel energy. Bio-fuel energy is from biofuels that is produced directly or indirectly from an inorganic material which is derived from plants and animals. Bio-fuel energy is the solar energy from the photosynthesis of plants process. Besides, biofuels may be derived from agricultural crops which is from certain energy crops and conventional food plants. It could be also obtained from the service-by-products and wastes.
Biomass Energy Methods: There are five biomass energy methods: 1- Direct combustion: This method refers to the burning of wood scarps and grasses. 2- Chemical conversion: biodiesel is a liquid fuel that can be used in engines instead of gasoline and has less pollution. We can get biodiesel from converting canola oils and soybean using a certain type of chemical during the process of chemical conversion. 3- Pyrolysis: The third method refers to heating biomass in order to get useful gases such as hydrogen and methane. Hydrogen is very important in producing water.
Biodiesel uses the same properties of diesel as fuel for cars. Biodiesel has many sources for it to be produced, these include soya, canola, jatropha, sunflower seed, etc. and animal fats (Khemani, 2011). Most of the used cooking oil thrown end up being collected to produce biodiesel; most restaurants donate their used cooking oil to prevent from throwing it in the drain. Rudolf Diesel who invented the diesel engine conducted an experiment by using vegetable oil as fuel for is engine (Pacific Biodiesel).
All of the things we use on daily basis have, in some way or another, consumed oil for its production and transportation; electricity, plastics, fabrics, glass, cars all have consumed oil at some point of their production. Although it may seem that we are chained to oil consumption, there are renewable alternatives such as nuclear power, solar power, wind power and biofuels. Renewable energy will be the most significant challenge for the oil industry. Various reasons and statistics about the newly discovered methods or indigenous sources will prove its significance. The aim of this study is to show that renewable energy is oil industry’s biggest threat.
In fact, fossil fuels supply about 90 per cent of the world’s energy. 4. Drawbacks of Fossil Fuels However, fossil fuels are non-renewable. That means they are not able to be replaced. Earth’s supply of fossil fuels is decreasing and will one day run out.
Alternative fuels for brick industry Though natural gas is the most common fuel in the brick industry worldwide, especially in developed countries, however, one can’t possibly deny the significance of the alternative fuels. In the current economy, natural gas may be cheaper than most of the fossil fuels on the market, but still, its combustion has a negative impact on the environment. On the other hand, alternative fuels such as biogas, biomass and its derivative fuels, have the potential to shield the brick manufacturers from the fluctuating price of the natural gas in the natural gas market. Also, renewable energy sources may be cheaper than the natural gas itself if all the factors of extraction, storage and distribution are considered. In this era of science and technology where the governments are more focused on the environmental impact of industrialization, alternative fuels such as biogas and biomass-derived fuels can be really
2.2 Biofuel Generally, biofuel is an alternative fuel to replace the use of gasoline fuel that we practiced in our cars currently. The biofuel produced from living organisms like plants and microalgae that more easy to find the sources and be process compare with the gasoline fuel that required a great deal of money and cannot be renewed as it depends on the fossil fuels from decomposed plants and animals that have been laid to rest in the earth for million years ago. Biofuel basically can be delineated as a fuel that takes energy from carbon fixation, a changeover process from the carbon dioxide of living organisms to an organic compound. Use of biofuel becoming so important days by days in the world, especially to car consumers as they need cheaper fuel, but effective and give big boost to the car operation to the maximum degree. And then, it didn't surprise at all as the world production of biofuel in 2007 was roughly 68 million liters and the numbers continues to ascend until the yield of biofuel reached to 105 billion liters in 2010.
Bio-fuels are roughly divided into four categories or generations The first generation bio-fuels are made from sugars, oil, animal fats and starches. These fuels are made from already known processes and technologies and include biodiesel, bio-alcohols, bio-ethanol and biogases (methane etc) captured from landfill
An example is carbon-based organically derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. Fossil fuels such as coal, petroleum, natural gas e.t.c are all non-renewable resources. Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a meaningful human time frame. Renewable energy resources include hydropower, biomass, geothermal, wind, solar e.t.c.
