If there is proper policy and implementation, Bangladesh’s energy crisis and organic fertilizer demand can be control through biogas plant. For their night soil disposal they needed to construct a septic tank for 250 users with Tk.60, 000.

Cattle dung, agricultural residue, poultry dropping, water hyacinth, human excreta may be used as raw materials for biogas plants.

Biogas comprises primarily methane (CH4) and carbon dioxide (CO2) and may have small amounts of hydrogen sulphide (H2S), moisture and siloxanes. By now Biogas plants have been constructed in all the remaining 4 buildings. Instead, LGED constructed a Biogas plant for Tk. A). It is an eco-friendly way to reduce pollution by making use of the source and emissions of the pollutant. Many countries in the West may experience a decline in living standards – with oil rationing and conservation measures introduced by governments and substantial reductions In travel, tourism and aviation. Therefore, the amount of biomass energy available in 2006 was 777 PC, which is equivalent to 216 Atwater-hours (Two). When the consumption is higher than production, pressure inside the digester falls and the expelled materials in the outlet compartment run back to the digester (iii) Plastic Cover digester: A long cylindrical polythene/PVC bag, half-buried longitudinally in the ground, is fed with fresh cow-dung slurry at one end and discharged at the other. For the first time there are more people aged over sixty than children under sixteen in many European countries.

So far, 35,000 biogas plants have been established for the production of gas for cooking purposes in the rural areas. Bangladesh Power Development Board. Sadly, 4.3 million people a year die prematurely from illness attributable to the household air pollution caused by the inefficient use of solid fuels for cooking.

For their night soil disposal they needed to construct a septic tank for 250 users with Tk.60, 000. The technology used to produce biogas is quite cheap. Later on BCSIR tried with fixed done type design and it has been successful in all biogas plants. energy consumption in 2006 was about 473 PJ. By 2020, the world is throwing into turmoil as demand for energy begins to greatly exceed the supply – crippling many economies and triggering widespread social unrest. Different poultry and dairy farm can mitigate their need of gas by using their own animal excreta. Burning them does not require any oxygen, so this is an eco-friendly way to create something useful.

Though other greenhouse gases appear to be only a small portion of the atmosphere, they cause much more harm to the climate. Biogas generators save women and children from the daunting task of firewood collection. The plastic bag type designs not used in Bangladesh it is used in China. Economic development. Biogas plants are creating employment opportunities for people across all types of communities. It takes the energy straight from them, drains their pollution, reduces the waste and thus causes less pollution to farms and nearby water sources. 400 per month. 4.

The unhygienic dumping zones in every city could me turned into a potential source of renewable energy by adopting active gas collection technology instead of spending money to manage the waste in that areas and keeping a huge land area unused. cause a rise of the earth’s. At the moment, many biogas plants still generate their power around the clock. Biomass can play a major role in reducing the reliance on fossil fuels by making use of thermochemical conversion technologies.

As an alternative source of energy 15 Biogas plants were installed, three persons were trained in the construction of Biogas plant.

Free Samples and Examples of Essays, Homeworks and any Papers. The huge amount of waste in the urban areas of Bangladesh due the rapid growth of population can be a potential source of biogas production.

Also the management of this huge amount of waste is a worth of large expense. Md. With the formation of gas, the bag swells like a balloon and the oasis led out to the point of use through a pipe by putting pressure on the balloon form outside In early ass’s, the floating type design Nas used for biogas plant.
