so these are the twelve twelve principles and I should say that the twelve principles are like any principles of framework aren't you no don't come from on high on stone tablets or anything else frameworks are thrown out into the scientific community to be beaten up and to be ripped apart and put back together and and to see if they have any utilit...

Questions & Answers

Q: What is the significance of waste prevention over treating waste?

Waste prevention is crucial because treating or cleaning up waste after it is formed is not only costly but also does not effectively close loops, leading to environmental contamination and exposure risks.

Q: What does "atom economy" mean in relation to synthetic methods?

Atom economy refers to the concept of maximizing the incorporation of all materials used into the final product, ensuring that atoms are efficiently utilized and minimizing waste generation.

Q: Why is it important to use substances with little to no toxicity?

Using substances with minimal toxicity reduces the risks to human health and the environment, promoting sustainability and avoiding harm caused by hazardous chemicals.

Q: How does preserving efficacy of function relate to chemical product design?

Chemical products should be designed to effectively perform their intended functions while minimizing toxicity, ensuring that they are both safe and efficient.

Summary & Key Takeaways

• The content introduces twelve principles of environmental framework that have been widely used and discussed for almost 20 years.

• Principle 1 highlights the importance of waste prevention over treating or cleaning up waste after it is formed.

• Principle 2 emphasizes designing synthetic methods that maximize the incorporation of all materials used into the final product.

• Principle 3 focuses on using substances that possess little to no toxicity to human health and the environment.
