Peptide manufacturing generates significant chemical waste. Green chemistry principles help reduce environmental impact while maintaining product quality.
| Solvent | Usage | Environmental Impact | Alternative |
|---|
| DMF | SPPS coupling | Hazardous, reproductive toxin | DMA, NMP |
| DCM | Extraction | Ozone depleting | 2-MeTHF |
| TFA | Cleavage | Corrosive, greenhouse gas | HCl/TFA mix |
| Acetonitrile | HPLC | Flammable, toxic | MeOH/Water |
| Metric | Traditional SPPS | Green SPPS |
|---|
| Solvent waste (L/g peptide) | 100-500 | 10-50 |
| Energy consumption | High | Medium |
| Atom economy | 30-50% | 50-70% |
| E-factor | 50-100 | 10-30 |
- Solvent recovery: Distill and reuse DMF, DCM
- TFA neutralization: Treat with calcium hydroxide before disposal
- Solid waste: Incinerate at licensed facility
- Aqueous waste: Treat before discharge
- Documentation: Maintain waste logs per regulations
| Regulation | Jurisdiction | Key Requirements |
|---|
| EPA RCRA | USA | Hazardous waste disposal |
| EU REACH | Europe | Chemical registration |
| OSHA | USA | Worker safety |
| GHS | Global | Hazard communication |
