Abstract
Fish waste affects the area surrounding and can change a broad ocean front zone at unlike environment levels by its effluents. To reduce the environmental impacts of improper disposal of both fish waste and sewage in the vicinity of the fishing industry in the coastal zone, an attempt has been made to convert the mixture of fish waste and sewage into energy. The by-product wastes mainly head, bones, skin, gut, tail and sometimes full whole fish waste. The main composition of fish waste is Protein 65%, fat 18% and minerals 17%. So, fish waste having a large amount of biodegradable matter when compared to fresh sewage and by adding higher amount of fish waste we can be able to generate higher methane emissions. The ultimate aim of the project is to find the optimum methane gas emission from fish waste mixed with fresh sewage using the anaerobic digestion for the experimental part. And for the stoichiometry combustion equation for the theoretical part. Using stoichiometries equations methane gas generated has been calculated from the mixture of sewage and fish waste. Using the Orsatâs apparatus methane gas generated has been measured from the mixture of sewage and fish waste. The correlation coefficient - R2 value is 0.9906 indicating a strong correlation for the predicted values and the measured values.
