Our innovation ColdHubs addresses the problem of food spoilage due to a lack of reliable cold storage at key points within the food supply chain. Food spoilage is caused by ambient temperature and relative humidity which facilitates fungal and bacteria decay. The problem is exacerbated by the absence of suitable on-farm and in-market cold storage facilities and unreliable electricity supply. Spoilage reduces the availability of safe, nutritious, and healthy food available for human consumption.
