C-MACC Weekly Sustainability and Energy Transition Report
When Inputs Bite Back: Cost Curves Rewrite Industry
- 1st Topic of the Week: Energy-driven resin repricing narrows virgin-PCR gaps, benefiting circular adoption and shifting advantage toward suppliers that control feedstock, specification, and customer collaboration.
- 2nd Topic of the Week: Ammonia price shocks are making fertilizer markets hydrogen’s first scalable commercial platform, strengthening green economics in China and blue returns in North America.
- Otherwise, gasoline premiums revive ethanol-blending economics, EU carbon prices slide from late-2025 highs, grid constraints reshape power markets, and lithium refining bottlenecks tighten.
Exhibit 1: Virgin plastic cost inflation temporarily narrows gap with mechanical and chemical recycling.
