Qualitative and Quantitative Feasibility of Biogas Production from Kitchen Waste

American Journal of Energy Engineering

This study focuses on production of biogas from kitchen waste using modified digester. The digester has been placed in four different conditions. As the result shows, production of gas gradually increased and peaked to 0.360, 0.260, 0.150 and 0.116m 3 at 9 th , 12 th , 17 th and 23 th days of the 1 st , 2 nd , 3 rd and 4 th sets respectively. Due to depletion of the developed culture and organic content of the waste, gas production becomes decreased and then nearly zero at 22 th and 29 th days of the 1 st and 2 nd sets. But For the last two cases production is not completed within thirty days. Finally, 10kg of food waste has been produced a total of 2.292, 1.783, 1.172 and 0.962m 3 of biogas from the 1 st , 2 nd , 3 rd and 4 th sets respectively and the best waste/water ratio is 1:2. Temperature, particle size and pH are the main factors affecting microbial activity and then methane production. Of those, temperature is the most important factor. Low pH decrease's the biogas production by facilitating hydrolysis and acidogenesis reactions and makes bacteria's to utilize the waste more readily. Generally, production of biogas in Shoarobit is more feasible, and takes short time than in Debre Berhan town.

Analysis on Different Operational Parameters of a Biogas Plant using Kitchen waste

The objective of this work is 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 biogas reactors on campus in the backyard of our hostels will be beneficial. Kitchen (food waste) was collected from different sources as feedstock for our reactor which works as anaerobic digester system to produce biogas energy. The anaerobic digestion of kitchen waste produces biogas, a valuable energy resource anaerobic digestion is a microbial process for production of biogas, which consist of primarily methane (CH 4 ) & carbon dioxide (CO 2 ). Biogas can be used as energy source and also for numerous purposes. But, any possible applications require 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 the alkalinity and pH to 7. For this reactor we have prepared our Inoculum than we installed batch reactors, 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 is a non-exhaustible of energy which can be formed from anaerobic fermentation of different types of biodegradable waste such as food waste, plant waste, animal waste sewage and other organic waste. The typical composition of Biogas includes CH4 (50–70%) which is responsible for maximum energy content along with CO2 (25–50%) that can be collected, stored and supplied. Biogas acts as a multipurpose and an eco- friendly sustainable resource of energy which can be utilized for cooking, electricity generation, lightning, heating etc. Biodegradable waste specifically produced in large amounts as a kitchen waste. In modern society, the solid waste per capita has been consistently increasing as of increase in population and change in socio-economic-cultural habits. The biogas production through the kitchen waste thereof provides a solution of disposal of solid waste. The bio gas production through anaerobic degradation pathways can be controlled and enhanced with the help of certain...

The Production of Biogas Using Kitchen Waste

Kitchen waste is the best alternative for biogas production in a community level biogas plant. It is produced when bacteria degrade organic matter in the absence of air. Biogas contains around 55‐65% of methane, 30‐40% of carbon dioxide. The calorific value of biogas is appreciably high (around 4700 kcal or 20 MJ at around 55% methane content). The gas can effectively be utilized for generation of power through a biogas based power‐generation system after dewatering and cleaning of the gas. In addition, the slurry produced in the process provides valuable organic manure for farming and sustaining the soil fertility. In this paper, an attempt has been made to test the performance of different ratio of kitchen waste in a metal made portable floating type biogas plant of volume capacity 0.018 m 3 for outdoor climatic condition of New Delhi, India. Each of the biogas plant 30 Kg slurry capacity in batch system for all measurement. During these period, the temperature, solar radiation and relative humidity have been measured. We have also analysed the constituent of biogas, pH, volume and rate of biogas production at different level of temperature observation on daily basis. Here we also compare the rate of biogas production from kitchen waste with the other energy sources used for cooking purposes like LPG, Kerosene and Coal.
