Principles of Green Chemistry

12 Principles of Green Engineering

• 7. Targeted durability, not immortality, should be a design goal.
• 8. Design for unnecessary capacity or capability (e.g., “one size fits all”) solutions should be considered a design flaw.

12 Principles of Green Engineering

• 9. Material diversity in multicomponent products should be minimized to promote disassembly and value retention.
• 10. Design of products, processes, and systems must include integration and interconnectivity with available energy and materials flows.

12 Principles of Green Engineering

• 11. Products, processes, and systems should be designed for performance in a commercial “afterlife”.
• 12. Material and energy inputs should be renewable rather than depleting.

Sandestin Declaration of Green Engineering Principles

• To fully implement Green Engineering solutions, engineers use the following principles:
• Engineer processes and products holistically, use systems analysis, and integrate environmental impact assessment tools
• 2. Conserve and improve natural ecosystems while protecting human health and well-being

Sandestin Declaration of Green Engineering Principles

• 3. Use life cycle thinking in all engineering activities
• 4. Ensure that all material and energy inputs and outputs are as inherently safe and benign as possible
• 5. Minimize depletion of natural resources

Sandestin Declaration of Green Engineering Principles

• 6. Strive to prevent waste
• 7. Develop and apply engineering solutions, being cognizant of local geography, aspirations and cultures

Sandestin Declaration of Green Engineering Principles

• 8. Create engineering solutions beyond current or dominant technologies; improve, innovate, and invent (technologies) to achieve sustainability
• 9. Actively engage communities and stakeholders in the development of engineering solutions
• There is a duty to inform society of the practice of Green Engineering
