Lack of proper, well-designed on-farm and off-farm storage facilities and unreliable electricity supply prevent smallholder farmers and other food supply chain actors from extending the shelf life of crops. Nigerian smallholder farmers and supply chain actors produce 23 million tonnes of fresh fruits and vegetables worth US$4 billion per year, of which an average of 45% of vegetables and 35% of fruits are lost after harvest. While rotting food is terrible in itself, it also produces methane, a potent greenhouse gas.
ColdHubs Ltd. has developed solar-powered refrigeration units that provide affordable cold storage to farmers. Their product is a solar-powered walk-in cooler that is placed in outdoor markets and farms to store and preserve fruits, vegetables and other perishable foods and extend their shelf life from 2 to 21 days.
