Biogas Production from Kitchen Waste


Abstract—

kitchen waste is obtained which can be utilized for better purposes. Biogas production requires Anaerobic digestion.Project was to Create an Organic Processing Facility to create biogas which will be more cost effective,eco-friendly,cut down on landfill waste, generate a high-quality renewable fuel, and reduce carbon dioxide & methane emissions. Overall by creating a biogas reactors oncampus in the backyard of our hostels willbe beneficial. Kitchen (food waste) was collected from differenthostels of National Institute of Technology,Rourkela’s Mess as feedstock for our reactor which works as anaerobic digester system to produce biogas energy.The anaerobic digestion of kitchen waste producesbiogas, a valuable energy resource Anaerobic digestion is a microbial process for production of biogas, which consist of Primarily methane (CH4) & carbon dioxide (CO2). Biogas Production from Kitchen Waste- Biogas can be used as energy source and also for numerous purposes. But,any possible applications requires knowledge & information about the composition and quantity of constituents in the biogas produced. The continuously-fed digester requires addition of sodium hydroxide(NaOH) to maintain thealkalinity and pHto 7.For this reactor we have prepared our Inoculum than we installedbatchreactors, to which inoculum of previous cow dung slurry along with the kitchen waste was added to develop our own Inoculum. A combination of these mixed inoculum was used for biogas production at 37°C in laboratory(small scale) reactor (20L capacity)In our study, the production of biogas and methane is done from the starch-rich and sugary material and is determined at laboratory scale using the simple digesters. Biogas Production from Kitchen Waste- Due to scarcity of petroleum and coal it threatens supply of fuel throughout the world also problem of their combustion ledsto research in different corners to get access the new sources of energy, like renewable energy resources. Solar energy, wind energy, different thermal and hydro sources of energy, biogas are all renewable energy resources. But, biogas is distinct from other renewable energies becauseof its characterstics of using,controlling and collecting organic wastes and at the same time producing fertilizer and water for use in agricultural irrigation. Biogas does not have any geographical limitations nor does it requires advanced technology for producing energy,also it is very simple to use and apply.Kitchen waste is organic material having the high calorific value and nutritive value to microbes, that’s why efficiency of methane production can be increased by several order of magnitude as said earlier.It means higher efficiency and size of reactor and cost of biogas production is reduced. Also in most of cities and places, kitchen waste is disposed in landfill or discarded which causes the public health hazards and diseses like malaria,cholera,typhoid. Inadequate management of wastes like uncontrolled dumping bears several adverse consequences: It not only leads to polluting surface and groundwater through leachate and further promotes the breeding of flies , mosquitoes, rats and other disease bearing vectors. Also, it emits unpleasant odour & methane which is a major greenhouse gas contributing to global warming.Mankind can tackle this problem(threat) successfully with the help of methane , however till now we have not been benifited, because of ignorance of basic sciences –likeoutput of work is dependent on energy available for doing that work
