Agriculture

Preserving the freshness of valuable commodities, such as wheat and canola, is a top priority within the agricultural industry. Nitrogen generators have revolutionised bulk silo storage, offering a safe, chemical-free and eco-friendly solution for protecting a variety of stored ingredients, including grains, cereals, pulses, and oilseeds.

Switching to a nitrogen generation system for crop storage is now easier and more cost-effective than ever.

How Does Nitrogen Protect Crops in Bulk Silo Storage?

Nitrogen effectively eliminates pests and prevents spoilage of grains and stored food by creating a nitrogen-controlled atmosphere. Nitrogen generators modify the air in the storage environment by increasing nitrogen and reducing oxygen levels. Low oxygen inhibits the growth of moulds, microbes and pests without the need for pesticides and preserves the quality of the stored products by preventing oxidation.

Benefits of Nitrogen Generators in Bulk Storage Protection

Nitrogen generators offer a range of benefits compared to traditional methods for agricultural bulk storage:

• Compliant with Australian regulations: Approved by DAFF and Grain Trade Australia with no special licensing required. It’s also safer under WHS laws as nitrogen is not classified as a poison.
• Safer for workers: Nitrogen is a non-toxic, inert gas that eliminates the need for handling hazardous chemicals during fumigation.
• Residue-free and export-ready: Nitrogen leaves no chemical residue, helping grain meet strict international export standards and support organic certification.
• Preserves product quality: It prevents oxidation, maintaining the crops's colour, taste, and nutritional value—especially important for high-quality and specialty crops. It can also extend shelf life, enabling longer storage without spoilage.
• Fast turnaround times: No post-treatment aeration required, meaning grain can be handled immediately after fumigation. The fumigation process is typically completed in around 7 days.
• No insect resistance: Pests are rapidly growing resistant to traditional fumigation chemicals. Unlike chemical treatments, nitrogen suffocates pests through oxygen depletion, a physical process that pests cannot develop resistance to.
• Cost-effective long-term solution: Reduces ongoing consumable costs and can cut ongoing fumigation expenses by up to 90% compared to traditional methods.

How We Helped One of Australia's Largest Grain Handlers

Gas Generation Australia partnered with a major grain export facility in Western Australia to implement a high-efficiency nitrogen fumigation system. By replacing phosphine with on-site nitrogen generation, the client cut fumigation time by two-thirds, eliminated chemical handling risks, and reduced treatment costs to as little as one-tenth of traditional methods. With proven results and seamless integration into existing infrastructure, this project is now being rolled out across all port facilities.
