China's grain storage capacity exceeded 700 mln tonnes by end of 2023

China's continued construction of grain warehouses brought the national grain storage capacity to over 700 million tonnes by the end of 2023, up 36 percent from 2014, according to an official at the National Food and Strategic Reserves Administration.

Since the start of the 14th Five-Year Plan period (2021-2025), China has built and upgraded grain storage facilities with a total capacity of over 65 million tonnes. Key performance indicators such as airtightness and thermal insulation levels have significantly improved, said Zhou Guanhua, director of the administration's safe storage and technology department, as quoted by Chinese-language newspaper Science and Technology Daily on Friday.

In recent years, China has established a comprehensive grain storage system that is compatible with grain production, reserves and distribution, Zhou said, adding that China's grain storage facilities have met the country's grain purchase and storage needs in terms of overall capacity.

Outdated means of storing grain, including stack storage and open-air piles, have been largely eliminated across the country, while "four-in-one" grain storage technologies – covering mechanical ventilation, fumigation, monitoring and cooling – have been adopted as a standard in state-owned grain warehouses, further improving grain storage quality, the official said.

China has also been promoting green grain storage technologies in its warehouses, covering such areas as temperature control, internal circulation and comprehensive pest control.

By the end of 2023, the total storage capacity of low-temperature and near-low-temperature grain warehouses nationwide had climbed to 200 million tonnes, and the comprehensive loss rate of state-owned grain warehouses remained within a reasonable range of 1 percent, Zhou said.
