Abstract
Pollutant emissions from developing countries are on the rise. Many of these countries are also suffering from social problems including poverty, food shortages, and unemployment. Agricultural development is a major key to better crop production, solution of the food shortage problem, as well as to job creation and income generation. Common flue gas desulfurization (FGD) that uses the wet limestone process for removing sulfur dioxide (SO2) from flue gas is not directly related to agriculture but is proposed as a means of transforming major air pollutants (sulfur oxides and nitrogen oxides) into agricultural fertilizer. This concept would contribute to the environment and economic development (agriculture in particular). Its feasibility is analyzed from different viewpoints—pollution control technology, secondary pollution, the fertilizer market, economic performance based on the Szechwan project, the effect of fertilization on agricultural productivity and soil quality, and the contribution of agriculture to society as a whole.
