12 Principles of Green Chemistry: Principle 7—A raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable.
12 Principles of Green Chemistry: Principle 10—Chemical products should be designed so that at the end of their function they break down into innocuous degradation products and do not persist in the environment.
