# Green Synthesis Evaluator

## Purpose

The Green Synthesis Evaluator skill provides comprehensive sustainability assessment for nanomaterial synthesis routes, enabling design of environmentally friendly processes through green chemistry metrics and lifecycle analysis.

## Capabilities

- Green chemistry metrics calculation (E-factor, atom economy)
- Lifecycle assessment integration
- Bio-based precursor database
- Solvent sustainability scoring
- Energy consumption estimation
- Waste minimization strategies

## Usage Guidelines

### Sustainability Assessment

1. **Green Chemistry Metrics**
   - E-factor = mass waste / mass product
   - Atom economy = MW product / MW reactants x 100%
   - Process mass intensity (PMI)

2. **Solvent Selection**
   - Use GSK solvent selection guide
   - Prefer water, ethanol, or bio-solvents
   - Avoid chlorinated and aromatic solvents

3. **Energy Optimization**
   - Minimize reaction temperatures
   - Reduce processing times
   - Consider microwave/ultrasonic assistance

## Process Integration

- Green Synthesis Route Development
- Nanoparticle Synthesis Protocol Development
