ACKNOWLEDGEMENT
Verily, all praise is due to Allah, the eternally besought of all, the most conclusive of all judges. Glory is unto Him whose aid and forgiveness we seek. May Allah extol and send blessings of peace upon His Slave and Messenger, the best of His creation, and the faithful to His revelation, Muhammad (S.A.W) the son of Abdullah; upon his family, his companions and those who have clutched to his Sunnah with their morals until the Day of Reckoning.
The number of words, sentences and paragraphs meant to seal and certify the approval of this project will be shortened without the recognition of the enormous task shouldered by my beloved parents, who were firmly behind me up to the fruition of this endeavor. Indeed, their much deserved reward is with Him in whose hands reside our lives.
I wish to register my weighty gratitude to my supervisor, Dr. A.O Musa, for his maximum effort in going through the scripts and making indispensable corrections. May the Almighty reward him.
As a final point, I will not fail to acknowledge the encouragement, counsel and support I received from my good friends and well wishers.
May Allah, Who is free from all error and absentmindedness, bless all of us, and may He cause the efforts of all drawn in to be purely for Him, and may He store its reward for us with Himself. Ameen.

ABSTRACT
Anaerobic digestion is a process that occurs in nature and produces biogas as a by-product. Biogas typically contains between 60 and 70 percent methane. This methane content makes biogas an excellent source of renewable energy to replace natural gas and other fossil fuels. Anaerobic treatment has been historically used to biologically stabilize high-strength wastes at a low cost. In many cases, the biogas has not been used as

    The environmental impacts of farming practices can also be reduced with the adoption of sustainable production methods in the agricultural sector. Growing corn, wheat, rice, and sugarcane produces large amounts of agricultural wastes, some of which are burned, degrading air quality. In the production of cellulosic ethanol, the bulk of the biomass would become a valuable source of energy rather than a waste product. In fact, municipal solid waste (MSW) includes a large volume of cellulosic material that has the potential to be converted to ethanol.…

    Converting Biomass, first goes through chemical and thermal to mechanical and finally to electrical. That is the process we use when we burn biomass. So an example would be cow manure and that would be changed into fuel. How? Well there is this process called Anaerobic digesting. This process is when microorganisms break down, in a no oxygen environment, material that is biodegradable. Biodegradable means that…

    Throughout the past few decades sources of renewable energy have been widely discussed due to the harmful impacts fossil fuels have on the environment combined with fluctuating petroleum prices and our growing demand for an ever depleting resource (Fletcher et al. 2011). Over the coming decades it is predicted that there will be an increase in the use of bioenergy systems (McBride et al. 2011). Bioenergy is commonly believed by both policy makers and environmentalists to be one of the…

    | Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane, the main component of natural gas, and probably the most abundant organic compound on earth. For this experiment we had created a bio gas generator. A biogas generator is any gas fuel derived from the decay of organic matter, as the mixture of methane and carbon dioxide produced by the bacterial decomposition of sewage, manure, garbage, or plant crops. Using a slurry mix of manure and cut grass we came up with the hypothesis “The more volume of slurry, the more gas will be produced”. Our independent variable was the volume of slurry, because we controlled how much slurry to put in the bottle, and the dependent variable was the methane gas.…

    Renewable Energy

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    Biodiesel

    The purpose of this experiment was to compare biodiesel to other fuels. The ecotoxicity of biodiesel was estimated, along with that of other biofuels through the germination of seeds in the presence of different concentrations of fuels. This resulted in biodiesel having an average of 79.4% germinated seeds in a 10% solution of fuel, compared to other fuels whose percentage of germinated seeds decreased with higher concentrations of fuel. In addition, biodiesel was also synthesized and its heat of combustion was found through the use of calorimetry. The heat capacity for the calorimeter was based on the heat of combustion for ethanol, which was then used to determine the heat of combustion for biodiesel. The average heat of combustion for biodiesel was ∆Hcomb= -13090.83 kJ/mole, as opposed to the theoretical value of -11496.6 kJ/mole, which resulted in a 13.9% difference. Furthermore, taking into consideration the ecotoxicity of biodiesel, its effect on the environment, and fuel efficiency, biodiesel proved to be the more favorable fuel relative to the other fuels tested. The goal of the experiment was to compare and determine the advantages of using biodiesel as a fuel as opposed to other fuels.…

    What is biogas and what is it used for? Biogas is a mixture of methane and carbon dioxide, produced by the breakdown of organic waste by bacteria without oxygen (anaerobic digestion). If you’ve ever seen bubbles rising from a swampy marshy area, that’s naturally produced methane. Like the gas in liquid petroleum gas canisters, methane can be burnt for cooking or lighting the house. It can also be used to power combustion engines to drive a motor or generate electricity.…
