Environmental Life Cycle Assessment (LCA) Of Wheat Cultivation In Agro industry company Of Iranian Novin(Aq-Qala)

Abstract

The unique and systematic solution to the problems existing in the energy and environmental sectors of Iran is to improveenergy productivity (EP) in various fields.. Despite the extensive researches on the energy consumption and optimization of crops in Iran and other countries, the direct study of pollution and greenhouse gas emissions has received less attention from researchers. The study of crop production from the viewpoint of environmental issues and emissions will be a solution tothe environmental protection and achievement of sustainable agriculture. In this study, environmental pollution and energy input/output were investigated in Agroindustry Company of Iranian Novin Farms,Golestan province. According to the results, the average of energy output to input ratio was 1.04,with average EP of 0.07 kg/MJ, in wheat production. The average energy intensity and net energy gain were 14.1 MJ/kg and 1298.3 MJ/ha, respectively. Nursing and tillage operations accounted for 57 and 24% of total energy input, respectively. The results of wheat LCAusingSIMAPRO software revealedthat the open water poisoning indexwas55845.08 kg 1.4-DCB eq. for the production of one ton of wheat.The global warming potentialwas 841 kg CO₂ due to diesel fuel consumption. Despite the negligibleshare of chemical pesticides from total energy consumption, a value of 257.3 kg was obtained for the human toxicity index per ton of the produced crop.
