Advantages And Disadvantages Of Biogas

Achieving solutions to possible shortage in fossil fuels and environmental problems that the world is facing today require long­term potential actions for sustainable development. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions[1].A naturally occurring gas formed as a by­product of the breakdown of organic waste materials in a low­oxygen (e.g., anaerobic) environment. Biogas is composed primarily of methane (typically 55% – 70% by volume) and carbon dioxide (typically 30% – 45%). Biogas may also include smaller amounts of hydrogen sulfide (typically 50 – 2000 parts per million [ppm]), water vapor (saturated), oxygen, and various trace hydrocarbons. Due to its lower methane content…show more content…
one type of biogas is produced by potential advantages include: The replacement of an anaerobic digestion or fermentation of biodegradable inefficient (but traditional) fuel with a more efficient and materials such as biomass, manure or sewage, municipal flexible one, the recoupment of the fertilizer value of the waste, green waste and energy crops [3]. Biogas technology is based on the phenomenon that in a number of countries when organic matter containing cellulose is fermented in After treatment biogas approximate to pure methane the absence of air (aerobically), combustible gases but with a calorific value of about 40 MJ/m . Biogas is an majorly (methane) is formed [4]. Producing and utilizing renewable energy – both in a global and a national context– is necessitated by the synergistic effect of climate change and the long term, continuous price rise of fossil fuels.[5]. there are several problems comes to run a biogas plant. in rural area a abundant amount of bio waste are discarded into river and open area which is very harmful to our heath. because it produced many dangeroures gasas. Improper handling and storage of methane is a very dangrour for human…show more content…
Industrial biogas is produced at sewage treatment plants (sludge fermentation stage), landfills, sites with industrial processing industry and at digestion plants for agricultural organic waste, both mesophilic (35 °C) and thermophilic (55 °C). Biogas from anaerobic digestion and landfills consists primarily of CH4 and CO2 .[7]. In this paper biomass like different type of wastes include convert into biogas by anaerobic digestion process. Figure No­1,Biogas coversion process Waste includes all items that people no longer have any use for, which they either intend to get rid of or have already discarded. Additionally, wastes are such items which people are require to discard, for example by lay because of their hazardous properties. Many items can be considered as waste e.g., household rubbish, sewage sludge, wastes from manufacturing activities, packaging items, discarded cars, old televisions, garden waste, old paint containers etc. Thus all our daily activities can give rise to a large variety of different wastes arising from different sources.[8]. Biogas resources include different type of wastes in india.in this paper we discuss seven types of wastes which is shown in this

    2. Why Choose Microalgae culture or Microalgae as an Ideal biomass? Or Microalgae: advantages and disadvantages The microalgae culture have the infinite potential to be used as primary producers of biomass in coming years, eventually they will turn out to be as most significant energy source. They can act as feedstock for several types of renewable fuels such as ethanol, methanol, biodiesel, methane and hydrogen. Table 1 represents certain feedstocks used for biofuel production (Chisti 2007; Dominguez-Faus

Oil on the other hand can be transported through pipelines and coal can be carried in dump trucks and other heavy vehicles (Future, 2009). 3. Another disadvantage would be the hydrogen fuel cell’s dependency on fossil fuels. Although hydrogen energy is renewable and its environmental impacts are minimal, other non-renewable sources like coal, oil and natural gas are needed to separate hydrogen from oxygen
