35 billion kilograms of grains wasted annually in China
Though China’s annual grain yield is increasing, the waste and loss of grain still remains abig problem. Between the processes of storing, transporting and processing grain, the totalannual loss of grain has reached 35 billion kilograms, equal to the total food required tosustain 200 million people in a year.
An official with the Agricultural Machinery Department said that the performance and theefficiency of those in charge of the harvest determines how much grain will be wasted. If aharvest driver pursues speed at the cost of proper operation, then grain will not beevacuated from the machine before fully detaching from the straw.
Moreover, though manual harvesting guarantees less waste, the airing process also costs afew grains. Poor storage and a lack of functioning granaries contribute to losses as well. Inaddition, damage caused by rats is another major issue. Grains that are processed multipletimes experience unnecessary losses in volume and nutrients.
Authorities have promoted the use of new technologies, such as grain conditionmonitoring, transverse ventilation, nitrogen-filled circulation cooling and more, todecrease wasted grain by 2.54 billion tons. Losses during packaging have alreadydecreased by 2 percent, owing to new transportation tools, containers and vehicles.
An official at the State Administration of Grain pointed out that outdated processingtechniques should be eliminated, and process and consumption should be both taken intoconsideration in order to further reduce the waste rate.
