Almost four million tons of citrus fruit were used by the Florida processing plants last year. Juice obtained from citrus represents only approximately half of the weight of the fruit. Two million tons of peel, pulp and seeds, accumulated yearly at processing plants, presents a challenge and an opportunity. This is a large amount of raw material, readily available, concentrated in a relatively small number of locations, and produced over a period of time which makes possible economical handling and processing.
