The ultimate goal of implementing 3R is to realize circular green economy, that is, only a small amount of natural resources can meet the needs of economic and social development. By saving, recycling and reusing waste resources, their underutilized values can be re-developed and utilized, thus generating new economic and social benefits.
2 1 century, the development direction of human society will not be based on more resource consumption, but on more resource saving, recycling and reuse.

Role of 3R:
The "3R" principle is helpful to change the environmental image of enterprises and make them change from passive to active. A typical example is that DuPont researchers creatively developed the "3R principle" into a "3R manufacturing method" in combination with the reality of the chemical industry, thus achieving the environmental protection goal of less or even zero emissions.
With the progress of science and technology, the technology of energy recovery and incineration pollution control of garbage has gradually matured, and the recovery of energy in garbage has gradually become a reality. 4R evolved from 3R, and 4R is: Reduce, Reuse, Recycle and Recovery. The fourth "R", that is, recovery (energy recovery), refers to the recovery of energy that cannot be further recovered through garbage incineration.
