Background and Objective: Technologies, although is useful to make development, has resulted in environmental degradation and resource depletion. One of the most important energy-consuming industries is food factories that led to release of pollutants into the air, water and soil. The aim of this study was evaluated pollutants emission from stack vegetable oil factory in north of Iran in the summer and fall of 2014.
Methods: The samples were taken from stack of factory. The rate of pollutants were determined the type of scrubber. Sampling was done twice in the summer which analyses determined the type of scrubber. After installation scrubber and change the type of fuel, Sampling was again conducted in the fall.
Results: The results showed that the installation of scrubber and change the type of fuel led to all of pollutants reached to the environmental standards of Iran.
Conclusions: Modification of fuel and installation the scrubber could be considered as a strategy to reduce pollutants.
