CONVERTING AGRICULTURAL WASTES INTO USEFUL PURPOSES: 

CONVERTING AGRICULTURAL WASTES INTO USEFUL PURPO SES T.DAVID. 2 nd MECH V V College of engineering

INTRODUCTION: 

INTRODUCTION Agricultural waste is waste produced as a result of various agricultural operations . It includes manure and other wastes from farms, poultry houses and slaughterhouses harvest waste fertilizer run- off from fields pesticides that enter into water, air or soils and salt and silt drained from fields.

BIOMASS: 

BIOMASS Globally, 140 billion metric tons of biomass is generated every year from agriculture. This volume of biomass can be converted to an enormous amount of energy and raw materials Biomass takes the form of residual stalks, straw, leaves, roots, husk, nut or seed shells, waste wood and animal husbandry waste .

AGRO WASTES TO PRODUCE ELECTRICITY: 

AGRO WASTES TO PRODUCE ELECTRICITY Latest technology and research have proved that it is possible to generate electricity 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 edible agricultural product. That would mean more power generation in less time and increased efficiency .

ELECTRICITY FROM ONION WASTES: : 

ELECTRICITY FROM ONION 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 offset 30,000 tons of CO2 from entering the atmosphere each year.

ADVANTAGES: 

ADVANTAGES Biomass is always available and can be produced as a renewable resource. Growing Biomass crops produce oxygen 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 for residential, industrial and agricultural use.

DISADVANTAGES: 

DISADVANTAGES Agricultural wastes will not be available if the basic crop is no longer grown. Additional work is needed in areas such as harvesting methods. Is in some cases is a major cause of pollution. Research is needed to reduce the costs of production of Biomass based fuels.

CONCLUTION: 

CONCLUTION To date agricultural wastes (grass, dry leaves, sugarcane trash, etc.. which are produced in huge quantities had been put to little use. This research involves conversion of agricultural wastes to char, by an environment friendly, continuous batch process, briquetting of the char into a solid fuel form and use of an efficient, clean and user-friendly stove ideally suited for the briquettes as fuel.
