estimating greenhouse gas emissions using emission factorsfrom the sugarcane development company, ahvaz, iran

Background: greenhouse gas (ghg) emissions are increasing worldwide. they have harmful effects on human health, animals, and plants and play a major role in global warming and acid rain.methods: this research investigated carbon dioxide (co2) and ch4 emissions obtained from different parts of the hakim farabi, dobal khazaei, and ramin factories which produce ethanol and yeast. seasonal rates of co2 at the soil surface at the studied sites were estimated from measurements made on location and at intervals with manual chambers. this study aimed to assess the production rate of ghg emissions (ch4, co2) in the sugar production units of hakim farabi, dobal khazaei, and ramin factories.results: mean concentrations of co2 and ch4 emissions are respectively 279 500.207 and 3087.07 tons/ year from the hakim farabi agroindustry, 106 985.24 and 1.14 tons/year at the dobal khazaei ethanol producing factory, and 124 766.17 and 1.93 tons/year at the ramin leavening producing factory.conclusion: sugar plant boilers and the burning of sugarcane contributed the most co2 and ch4 emissions, respectively. moreover, lime kilns and diesel generators showed the least carbon dioxide and methane emissions, respectively.
