Sustainability Report — Herbal Hair Oil (short, scientific, 2025)

1) Product snapshot

Name: Herbal Hair Oil Unit: 100 mL amber glass bottle (consumer) Key inputs: Cold-pressed herbal oils (e.g., coconut/sesame base), botanical extracts (henna, bhringraj, amla), natural antioxidants (vitamin E), no synthetic fragrances or petrochemicals.

2) Core environmental metrics (per 100 mL unit — representative estimates)

• Carbon footprint: 30 kg CO₂e / unit
• Water footprint: 80 L / unit
• Renewable content: >98% (plant-based feedstocks)
• Formulation biodegradability: >95% (readily biodegradable under OECD-like tests)
• Packaging recyclability: Amber glass bottle + paper label ≈ 97% recyclable

3) Scientific calculations — compact examples

1. Annual production example (20,000 units/year) [ \text{Total CO₂e} = 20{,}000 \times 0.30 = 6{,}000\ \text{kg CO₂e/year} ] Trees equivalent (1 mature tree ≈ 22 kg CO₂/year): [ 6{,}000 \div 22 \approx 272.7 \Rightarrow \mathbf{~273\ trees/year} ]
2. Local sourcing reduction (15% transport cut) New per-unit CO₂e: (0.30 \times (1 - 0.15) = 0.255\ \text{kg CO₂e}) Annual CO₂e saved at 20,000 units: [ (0.30 - 0.255) \times 20{,}000 = 0.045 \times 20{,}000 = \mathbf{900\ kg\ CO₂e} ]
3. Packaging circularity (simple metric) If recyclable fraction = 0.97 and procured recycled-content = 40%: [ \text{Effective circularity} = 0.97 \times 0.40 = 0.388 ;(\mathbf{38.8%}) ]

4) Ingredient & processing notes (scientific)

• Cold-press extraction typically uses ≈0.8–1.2 kWh/kg and preserves actives, lowering need for chemical processing.
• High renewable fraction minimizes fossil feedstock impacts; ensure palm-free or RSPO-certified oils to avoid deforestation.
• Biodegradability & ecotoxicity: botanical oils and vitamin E show low aquatic toxicity (LC₅₀ well above concern thresholds).

5) Sustainability scoring (1–10)

Category	Score
Carbon efficiency	9
Water efficiency	8
Renewable material use	10
Biodegradability	9
Packaging circularity	8

Overall Sustainability Index (SI) = ((9+8+10+9+8)/5 = \mathbf{8.8/10})

6) Quick recommendations (high impact)

1. Prioritize local herb sourcing (saves ~15% transport emissions).
2. Maintain cold-press extraction and optimize energy (use renewable electricity) to lower kWh/kg.
3. Use refill pouches or deposit/refill scheme to improve real world circularity beyond the 38.8% metric.
4. Require sustainable oil sourcing certifications (avoid deforestation).
5. Label biodegradability & disposal instructions to reduce contamination of recycling streams.

Conclusion (one line)

Herbal Hair Oil is highly sustainable (SI ≈ 8.8/10) thanks to >98% renewable inputs and strong biodegradability; targeting local sourcing and refill systems can cut ~15% transport emissions and materially improve circularity.
