Life Cycle Assessment for Open field and Greenhouse Peppers

Demographic and economic growth leads naturally to an increase in demand for resources, with the extraction, processing, use and disposal of these resources causing a wide variety of environmental problems such as wastes and emissions in the air and in the water. To analyze and manage the subsequent impacts on the environment, tools such as life cycle assessment (LCA) is being widely used. Due to the increasing of interest about food safety and environmental performance, life cycle assessment for agri-food sector is being essential part. So this paper carries out life cycle assessment for open field and greenhouse peppers. The results of assessment, open field peppers are more environmental friendly at four impact categories; abiotic resource depletion, global warming potential, fresh water aquatic eco toxicity potential and terrestrial eco toxicity potential. And the other impact categories show reverse trends. Key issue of environmental burden for open field peppers are production of inorganic fertilizer and other greenhouse material, and for greenhouse peppers are direct air emission from energy use and crude that oil extracted for diesel production.
