INTRODUCTION

Agricultural waste is waste produced asa result of various agricultural

operations . It includes manure and other

wastes from farms, poultry houses and

slaughterhouses harvest waste fertilizer

BIOMASSGlobally, 140 billion metric tons of

biomass is generated every year from

agriculture.

o This volume of biomass can be

converted to an enormous amount of

energy and raw materials

o Biomass takes the form of residual

stalks, straw, leaves, roots, husk, nut

AGRO WASTES TO PRODUCEELECTRICITY

Latest technology and research haveproved that it is possible to generateelectricity with nothing but pure

agricultural waste. That would mean recycling animal

dung, discarded plant husk, rotten

leaves etc. to produce electrical power ,and all this without using any edibleagricultural product.

That would mean more power

WASTES:Presently the company produces over

300,000 pounds of onion waste each

day.

which is utilized by the system to

generate electricity, enough to power

460 homes.

The electricity generated is stored in

two 300KW fuel cells which will also

ADVANTAGES Biomass is always available and can

be produced as a renewableresource.

Growing Biomass crops produceoxygen and use up carbon dioxide.

Less money spent on foreign oil. Biomass used as a fuel reduces need

for fossil fuels for the production of

heat, steam, and electricity forresidential industrial and a ricultural

DISADVANTAGES Agricultural wastes will not be

available if the basic crop is nolonger grown.

Additional work is needed in areassuch as harvesting methods.

Is in some cases is a major cause of pollution. Research is needed to reduce the

costs of production of Biomass basedfuels.

CONCLUTION

To date agricultural wastes (grass,dry leaves, sugarcane trash, etc..which are produced in huge quantitieshad been put to little use. Thisresearch involves conversion of agricultural wastes to char, by an

environment friendly, continuous batchprocess, briquetting of the char into asolid fuel form and use of an efficient,clean and user-friendly stove ideallysuited for the briquettes as fuel.
