Do you know the word ”green chemistry”？
It can also be called “environmentally friendly chemistry” or something similar.
Green Chemistry is a practical way of thinking about how people who make chemicals can make things in an environmentally friendly way.In Japan, GSCN defines Green Sustainable Chemistry (so called Green Chemistry) as “the chemistry which is friendly for human and environment and supports the development of sustainable society.”
In this way of thinking, environmental negative effects (risk) is regarded as “ risk = hazard × exposure“.
It focuses not on the way of reducing the exposure, but on the hazard management that reduce the risk of health and environment by reducing the fundamental hazard in the making process of the products. In easier words, it is the way of thinking not to drive the exit after making but to stop the born of dirty itself by using of the subjects with less hazard in na making process.Simply put, the idea is to cut off the generation of contamination itself by using less hazardous materials at the manufacturing stage, rather than tinkering with the treatment outlets after making the product.
