⚖️ Fermentation vs Hydration Comparison
| Aspect | Fermentation | Hydration of Ethene |
|---|---|---|
| Raw Materials | Sugar/starch (renewable) | Ethene from crude oil (finite) |
| Temperature | 25-35°C (room temp) | 300°C (high energy) |
| Speed | Days to weeks | Continuous process |
| Purity | Low (needs distillation) | High (pure ethanol) |
| Environmental | Carbon neutral (renewable) | Uses fossil fuels |
| Scale | Batch process | Large-scale continuous |
