El-Khateeb (2001) reported that in Egypt there are about
15 million tons/year of the field raw materials available as vegetative
residues of corn stalks and rice straw. They are currently used as fuel.
Roof-top storage of cotton, corn stalks and rice straw bundles present
serious fire hazards.
Beside, it offers a dwelling environment for cotton boll worms. The
quantities of crop residues in Egypt are estimated about 18.7 million
ton/year, 53 % of which (9.91 million ton) are directly burned. This
causes great losses of energy and air pollution. The burning of cotton
residues (1.24million ton/year) causes a loss of 532.000 equivalent ton of
hydrocarbon fuel (1.806 million LE). Corn fields provide 4.07 and 0.61
million ton of dry stalks and cubs respectively (based on mean yield of
0.43 ton/fed),
