Green engineering is the design, commercialization, and use of process and products in such a way that it reduces pollution, promotes sustainability, and minimizes the risk to human health and environment without harming economic viability and efficiency. It embraces the concept that decisions to protect human health and the environment can have the greatest impact and cost-effectiveness when applied early, in the design and development phase of a process or product. There are 12 Principles on Green engineering: (a) Inherent Rather Than Circumstantial (b) Prevention Instead of Treatment (c) Design for Separation (d) Maximize Efficiency (e) Output-Pulled Versus Input-Pushed (f) Conserve Complexity (g) Durability Rather Than Immortality (h) Meet Need, Minimize Excess (i) Minimize Material Diversity (j) Integrate Material and Energy Flows (k) Design for Commercial "Afterlife" (l) Renewable Rather Than Depleting
