Study Notes
Preventing Waste
- Design chemical processes to eliminate waste, focusing on prevention rather than remediation.
Designing Safer Chemicals and Products
- Aim for chemical products that are effective yet carry minimal to no toxicity.
Less Hazardous Chemical Synthesis
- Create methods that utilize substances with low toxicity to protect humans and the environment.
Use of Renewable Raw Materials
- Source materials from renewable resources, such as plant-based materials, to support sustainability.
Catalysts Over Stoichiometric Reagents
- Implement catalysts that can facilitate multiple reactions while being used in small quantities, thus reducing waste.
Avoiding Chemical Derivatives
- Minimize the use of temporary modifications like blocking or protecting groups to reduce additional reagents and waste.
Maximizing Atom Economy
- Ensure syntheses are structured so that the final product retains the highest possible proportion of initial materials, minimizing waste "atoms."
Safer Solvents and Reaction Conditions
- Steer clear of toxic solvents for dissolving reactants or extracting products to enhance safety.
Energy Efficiency
- Reduce energy consumption by performing reactions at room temperature and pressure whenever feasible.
Designing for Degradation
- Create chemical products that can safely break down into non-toxic substances after usage to prevent environmental accumulation.
Real-Time Analysis for Pollution Prevention
- Incorporate continuous monitoring during processes to minimize or eliminate unwanted by-products.
Minimizing Potential for Accidents
- Design chemicals and their forms to reduce risks of accidents, including explosions, fires, or environmental releases.
