A Self Sufficient Energy Model for Poultry Farms in Bangladesh to Reduce Greenhouse Gas Emission and Increase Energy Efficiency

Abstract

There are over two hundred thousand of poultry farms in Bangladesh. With the annual growth rate of twenty five percent, the number is increasing rapidly. Most of these poultry farms draw their required electricity from the national grid; few of them use natural gas or diesel generators as the sources of energy. Very small numbers of them use poultry droppings for producing biogas to generate electricity and for cooking. But these biogas plants barely run at the peak of their capacity. The over reliance on national grid and fossil fuels aids to the emission of greenhouse gases and it is going to spiral up every year. But the poultry farms can produce their own energy from the poultry droppings which will reduce annual costs, greenhouse gas emission and they can even produce fertilizer from the biogas plant which will add to the generated revenue. The aim of this study is to divulge the possibility of self sufficient poultry farms using their poultry droppings only. A comparison is made among the annual costs, energy efficiency and greenhouse gases emissions from different sources of energy or different mix of them. It has been found that co-production of electricity and fertilizer optimizes the mentioned constraints.
