The HEAR (High Erucic Acid Rapeseed) ecosystem links agricultural production, processing facilities, and end‑use applications through a series of defined value‑creation stages. Upstream activities comprise seed breeders, agronomists, and raw‑material suppliers who generate erucic‑rich rapeseed kernels. Midstream actors include crushing plants, oil extraction facilities, and specialty chemical manufacturers that convert kernels into oil, fatty acids, and derivative polymers. Downstream participants consist of distributors, formulation houses, and industrial end users such as lubricant producers, polymer manufacturers, and specialty coating firms. Technology providers and equipment manufacturers support each stage with processing, analytical, and automation solutions, while regulatory bodies define safety and compositional standards that shape market entry. Value is captured primarily through margin differentials between raw seed costs and premium specialty products.
