What really happens to mulch films after they're used—and which options are truly sustainable? In this episode, PhD candidate Oluwatunmise Dada joins us to break down the full cradle‑to‑grave life cycle of biodegradable and polyethylene mulches in California's strawberry systems.

We explore:

• How PBAT, PLA, and TPS mulch formulations differ

• Why soil biodegradation consistently outperforms other end‑of‑life pathways

• The hidden environmental costs of landfilling PE mulch

• What sensitivity analysis reveals about degradation rates and transport distances

• Key limitations in current LCA methods for soil‑biodegradable materials

• Practical takeaways for growers deciding whether to adopt BDMs

Dada also shares what excites him most about the future of sustainable materials in agriculture, and what's next as he approaches the finish line of his PhD journey.

If you're a grower, researcher, or anyone curious about the future of mulch sustainability, this episode offers clear, science‑based insights you won't want to miss.
