In the view of our points, tThe twelve principles are consideredwould be still the guidinge principles to study green chemistry aftertime，but two new principles cshould be added，that is，design and manufacture of materials which could be reclaimed and used time after time，such as catalysts，chiral reagents etc.et. al，as well as improvement of former chemical engineering processes and techniquecs by using process intensification and integration etc.et. al.. Green chemistry and chemical technology should be as an inde
