Abstract:

Aim of the study is to support the development & improved practice on calculating of methane emissions from solid waste disposal. At the bio-methanation plant and waste disposing sites (SWDS) the degradable organic carbon in waste is decomposed by bacteria under anaerobic conditions into methane and other compounds. The SW disposal in many growing countries, especially poor and some concern is expressed also on the suitability of some of the default parameters in their conditions. Improvements in activity data collection and emission factors are needed in many countries. By studying and observing different site we concluded that institutional waste is not used for bio-methanation process. Only degradable Waste of houses and hotel is used for methanation that is 5 tonnes of degradable waste produce 20 m3 of methane. To increase the methanation and to alter the rate of reaction in the capsule we use grains, cattle dung and ruminant under fix and constant temperature similarly landfills gas (LFG) is produced in landfills due to the anaerobic digestion by microbes on any organic matter. Major constituents of LFG are: Methane (45 – 60%), Carbon Dioxide (40 – 50 %), Nitrous oxide (2 – 5%), Oxygen (0.1 1.0%), Ammonia (0.1 - 1.0%), Hydrogen (0 - 0.2%) and Volatile organic compounds. Microorganisms decomposes waste mass into Methane gas. First Stage: Aerobic Organisms Converts Waste into Simple Organic Compounds, CO2 & H2O. Second Stage: Anaerobic Organism Converts Organic Compounds Into H2, NH3, H2O, CO2 & Organic Acids. Third Stage: Methane Forming Organism Converts Organic Acid Into CH4.
