Green Chemistry—Correlation Between Cause and Effect: A Guest Editorial

Abstract Green chemistry represents an actual tendency to improve the quality of different kinds of technologies used in chemical industries. It represents an improvement of chemical engineering to develop unpolluted systems for producing various kinds of chemicals. The development of this idea is due to the studies on environmental pollution of air, water, and soil, using up‐to‐date analytical techniques. It represents a perfect correlation between chemical technologies (cause) and analytical techniques (which study the pollutants, effects). In these conditions is imposed a perfect cooperation between technologist and system analyst to assure an improvement, step by step, of chemical production.
