The Compostable Masterbatch segmentation mirrors the application hierarchy but with distinct weighting. Packaging—focused on compostable food trays, bags, and take‑away containers—captures the dominant share at approximately 45 % of the market, driven by regulatory pressure on single‑use plastics. Agriculture (e.g., compostable mulch and seed‑coating films) follows with 20 %, while Consumer goods (biodegradable utensils, personal care items) hold 15 %. Horticulture and soil‑enhancement products contribute 10 %, and Textiles (non‑woven fabrics, disposable apparel) account for the final 10 %. In the Types category, cellulose‑based masterbatches (nano‑cellulose, regenerated cellulose), PLA‑based grades (standard and high‑crystallinity variants), PBAT‑based blends (polybutylene adipate terephthalate), starch‑based formulations (modified starch), and multi‑polymer blends dominate. PLA and PBAT are prevalent in packaging due to their mechanical strength, whereas cellulose and starch are favored in horticulture for rapid degradation, collectively defining the market’s composition.
