IoT Innovations Cut Food Waste in Agriculture—Centaur Analytics' Breakthrough

It’s rare to find a tech startup whose founding team blends agronomy, entomology, and data science—yet that’s exactly what Centaur Analytics offers.

IoT’s true promise lies in applying digital tools to age‑old challenges. Food waste—especially post‑harvest loss—has long plagued agriculture worldwide.

UN FAO data reveal that roughly $1 trillion worth of crops are lost each year after harvest, spanning farm, shelf, and fork. Even in technologically advanced regions such as the EU, post‑harvest losses for grains and cereals exceed 10%, while developing nations in Africa and industrialized Asia see even higher rates. These losses occur during raw material storage, processing (e.g., milling), and the distribution chain.

Centaur Analytics, the first full‑stack IoT company dedicated to real‑time monitoring and protection of stored agri‑products, is directly addressing this issue. Their end‑to‑end solutions focus on the quality and safety of stored goods, with a mission to dramatically increase post‑harvest yields and eliminate waste from farm to shelf.

I recently spoke with Dr. Sotiris Bantas, co‑founder and CEO of Centaur Analytics, about their pioneering work. He explained the magnitude of the problem:

"We’re basically losing about one‑third of our annual output globally. In the developing world, especially Africa, wheat and corn often suffer insect infestation, leading to spoilage. In developed countries, 17% of produce is not used for food or processing—it’s either dumped, turned into animal feed, or used for biofuel. Much of it is simply wasted and lost," Bantas said.

What Goes Wrong in Crop Storage

Storing crops in large metal silos exposes them to moisture, temperature fluctuations, and insect infestation—factors that can accelerate spoilage. Traditional approaches have required farmers to physically inspect each silo, a time‑consuming and imprecise method.

Insects are particularly problematic: they consume the crop, increase moisture levels, and create conditions conducive to further degradation. Treatments typically involve fumigants such as phosphine, applied over several days—often up to a week.

"Fumigation is used across a range of crops—tobacco, grain, rice, feeds, fresh fruit—but historically it has been applied without real‑time monitoring," Bantas noted. He warned that improper dosing—too low temperature, incorrect dosage, or insufficient duration—can harden insects, prompting them to evolve resistance and rendering the treatment ineffective. Many farmers have been under‑dosing or mis‑timing fumigations, according to Bantas.

Centaur’s proprietary wireless sensors “sniff” storage conditions inside shipping containers, grain bins, and bunkers—capable of transmitting data even through metal walls, a challenge for most existing sensors. These devices feed entomological models and predictive analytics directly to users.

With real‑time alerts, farmers can proactively adjust fumigation schedules and pest control practices to ensure product safety and quality. The technology also detects temperature anomalies; a hot spot often signals the onset of infestation or spoilage, allowing for early intervention.

The Farmer Has Become Connected

Today’s farmers are increasingly tech‑savvy, thanks in part to widespread smartphone and tablet adoption. Bantas observes that technology has become so intuitive that farmers now rely on digital dashboards to anticipate weather patterns, plan harvests, and monitor storage conditions without physically visiting silos.

Centaur recently secured a $1.3 million funding round—a significant milestone in Greece’s challenging startup landscape. As the first mover in this niche, Centaur offers a globally relevant solution that benefits farmers from Australia to Algeria, addressing food security for current and future generations.
