Biogas Production from Vegetable Waste
Biogas Production from Vegetable Waste report
The present work explores the production of biogas from fruit and vegetable wastes mixed with cow manure in an anaerobic digester. The total solid, volatile solids, moisture content and ash content of the wastes were examined. The materials used as feed were avocado, papaya, mango, tomato, banana peel, and cow manure. Varying volumes of digesters were employed for biogas generation. The combustibility of the gas so generated was tested. The anaerobic digestion of fruit and vegetable wastes mixed with different waste took 55 days to produce biogas (for complete digestion). Anaerobic digestion is very sensitive to change in pH and it is important to maintain pH of 6.7-7.4 for healthy system. The temperature of the digester and the environment also affects the anaerobic digestion process. Upon adjustment of the factors affecting anaerobic digestion, it is felt that co-digestion between FVW and CM produces biogas without need of nutrient or chemical addition to the system. The search for alternative source of energy such as biogas should be intensified so that ecological disasters like environmental pollution, deforestation, desertification and erosion can be arrested.Development of renewable and sustainable energy source is the best solution to the country’s energy demands .Biogas Production from Vegetable Waste It is much desirable that the renewable energy to be developed has no adverse effects on the environment. Surely, productions of renewable energy from materials that are readily and locally available are extremely advantageous and reduce the cost of its production. Environmentally friendly individuals may choose to compost their food waste to acquire a useful fertilizer or soil amendment; however, this process does not allow a means to capture the energy that is locked up in waste. Many municipal waste management programs do attempt to harness organic waste energy through combustion in waste-to-energy plants and methane collection from microorganism activity in landfills. While such systems make use of the energy available in food waste, they do not directly benefit the individuals who produce the waste, and may also involve additional costs to those individuals related to collection.
