The wide diversity of different grains produced by organic farmers, as a result of their long-term crop rotation systems, means a significant number of dedicated silos are needed to meet the enhanced requirements for quality and traceability. These are often unavailable in the existing storage facilitates used by the conventional feed and food chain. Coopérative régionale  d’agriculture biologique (CORAB), an organic grain cooperative, established in 1998 in western France, faced significant challenges in this respect, due to the prohibition of artificial preservatives in organic storage. Since the available silo infrastructure failed to meet the requirements, CORAB needed a technical innovation.
