What iswaste?

Waste can be defined as useless,unwanted and discarded materialscoming from production andconsumption.

Such as kitchen garbage, Bio-degradable municipal waste(BMW), municipal solid waste(MSW) etc.

Solid waste management has

become a serious environmentalproblem all over the world.

Resource recovery from solidwaste and Recycling is considered

as a viable management option.

According to Power Ministry,

Bangladesh produces up to 4,000MW of electricity everyday against aminimum daily demand for 6,000MW.

In the rural areas the demand stands at some 2,400 MW per day but theRural Electrification Board (REB) can supply barely half ofthat.

In the world, 1.4 to 1.6 billion people

according to the U.N. livewithout

electricity!!

Energy, in any form, plays the most important

role in the modern world. We need energyespecially Green electrical energy in our dailyneeds .

Purpose of study

To develop a Microbial Fuel cell by using thekitchen garbage (KG) for bio-electricitygeneration

To convert/recycled KG for soil conditionerby Hybrid composting method as a by-product of bio-electricity.

Microbial Fuel Cells (MFC)


10/2110

What is MFC???

Microbial fuel cell (MFC)s are bio-

electrochemical devices which convertbiomass into electricity through themetabolic activity of the microorganisms.

Living Bacteria generate electricity in the normal course of metabolizing nutrients.

This metabolic process delivers sustainable, renewable, commercially valuable electricity.

Conclusions

MFC by using Kitchen Garbage is provedto be good way for bio-electricitygeneration

Sustainable, Renewable, Green energy.

The by-product of the electricitygeneration by MFC can be used as soilconditioner
