1: It is better to prevent waste than to treat or clean up waste after it is formed.

10: Chemical products should be designed so that at the end of their function they do not persist in the environment and break down into innocuous degradation products.

4: Chemical products should be designed to preserve efficacy of function while reducing toxicity 5: The use of auxiliary substances(e.g. solvents, separation agents) should be made unnecessary wherever possible and innocuous when used. 6: Energy requirements should be recognized for their environmental and economical impacts and should be minimized.
