Despite India being the worlds largest producer of milk and second largest producer of fruits and vegetables, about 40 to 50 per cent of the total output valued of $440 billion ends up being wasted, a study said here on Tuesday. "India has about 6,300 cold storage facilities with a capacity of 30.11 million tons, which are only able to store about 11 per cent of the country's total perishable produce," said D.S. Rawat, the Assocham Secretary General.
