Abstract
Resource recovery and recycling of organic waste is a great challenge in the world. The unmanaged organic waste causes a great damage to the environment and the public health both in the developing countries and industrial parts of the world. In this research, an innovative method was adopted to generate bioelectricity from the organic waste by using the Microbial Fuel Cell (MFC). Various types of organic wastes such as livestock waste, food waste, fruit waste were used as the substrates of the microbial fuel cell. All the experiments were carried out in the same sized one chamber microbial fuel cell and the similar electrode materials. It was observed that all the organic wastes can be used to generate bioelectricity through microbial fuel cell. The generated electricity can be used in several environmental monitoring sensors and can be used as an alternate power source in the developing countries. The by-products of the bioelectricity generation can be used as soil conditioner in the organic depleted soil and agricultural fields.

1.1 Organic waste stateOrganic waste is generated in our everyday life
The organic content of cow dung was higher than the chicken dropping. This could be a reason why the voltage is higher while using the cow dung. Both feedstock waste can be used for the bioelectricity generation in the microbial fuel cell
Various kinds of organic waste such as livestock waste, kitchen garbage, agricultural waste can be used as a source of biomass for bioelectricity generation through Microbial Fuel Cell (MFC)
Summary
Organic waste is generated in our everyday life. The amount of organic waste is increasing all over the world. The recycling rate of organic waste is not prominent both in developing countries and the developed countries. In Japan, the organic waste is burnt in the incineration plants [1]. The higher content of moisture of the organic waste can reduce the calorific value. The unmanaged organic waste has created several environmental pollutions and health hazards, especially in the developing countries. The traditional method of organic waste management such as composting is often not suitable and caused problems in the urban areas [2]. To find some innovative method to recycle and resource recovery from organic waste is very crucial in recent time
