Strella Biotechnology

Strella Biotechnology is a food-waste technology company headquartered in Seattle, Washington, founded to give cold-storage and packing house operators real-time visibility into produce ripeness and spoilage risk. The company’s chemiresistive sensors, built on polymer nanowire and carbon-nanotube sensing elements, detect the ethylene, oxygen, carbon dioxide, temperature and humidity levels that drive fruit ripening.

Its Monitor sensors feed data into the Storage, Ripen and Sequence products, which respectively predict produce maturity during storage, automate ripening rooms and sequence shipments to reduce shrink. The company reports its sensors operate in 26 countries, have tracked more than 2 billion pounds of produce, helped save roughly 20 million pounds from spoilage, and are used to monitor around 15 percent of apples grown in the United States.

1. Nanosensor core: chemiresistive sensors using polymer nanowires and carbon nanotubes.

2. Multi-gas detection: tracks ethylene, O2, CO2, temperature and humidity in real time.

3. Storage: predicts produce maturity to flag inventory before it spoils.

4. Ripen: automates ripening-room conditions for consistent fruit quality.

5. Sequence: prioritises shipment order across warehouses to cut shrink.

6. Proven scale: deployed in 26 countries, tracking 2 billion+ pounds of produce.
