New Steel Silos Boost Food Security in Bhutan Nepal

Food security remains a cornerstone of national stability, with improving storage capacity and reducing post-harvest losses emerging as critical priorities worldwide. Addressing this need, a new generation of flat-bottom steel grain silos is being deployed across Bhutan and Nepal to enhance local food reserves.

The innovative silos feature zinc-aluminum alloy steel construction, offering superior corrosion resistance and durability that significantly extends operational lifespan. With a single-unit storage capacity of 5,000 metric tons and an external diameter of 25 meters, these cylindrical structures are specifically engineered for optimal grain preservation.

Compared to traditional storage facilities, the alloy steel silos demonstrate marked improvements in airtight sealing, moisture control, and pest prevention —key factors that minimize spoilage and maintain nutritional quality during extended storage periods.

Manufactured by a specialized industrial equipment producer that also supplies liquid storage tanks and wastewater treatment containers, these silos represent a comprehensive approach to storage solutions. Their implementation is expected to substantially upgrade grain preservation infrastructure in both Himalayan nations.

Food security experts emphasize that advancements in storage technology constitute a vital component of sustainable agriculture systems. The adoption of modern silo designs and advanced materials can dramatically reduce post-harvest losses—currently estimated at 14% of global food production—while improving utilization efficiency.

As climate change and geopolitical instability exacerbate global food supply challenges, such technological innovations in grain storage are anticipated to play an increasingly important role for developing nations seeking to strengthen their food security frameworks.
