Case Study: 2 Leafline Eco — Advanced Case Studies: Sugarcane Bagasse Tableware

Objective: Move to bagasse in all to‑go venues; increase compost capture while maintaining throughput during peak. Design: Pre/post with matched time‑of‑day audits for 8 weeks. Key Results Peak throughput unchanged (0.0 sec delta; 37.8s/order both periods). Compost capture: +29.4 pts (to 61.3%). Contamination: −14.8 pts (to 11.2%). Student satisfaction (to‑go durability): 4.4/5 → 4.6/5.
