ClassNK has officially certified a new catalyst system developed to extend the shelf life of produce onboard vessels. The technology works by scrubbing ethylene gas from air circulation systems in refrigerated storage.
Why it matters
By slowing the ripening process of fruits and vegetables, this system helps maritime operators improve food quality for crews and significantly reduce onboard food waste.
The Freshness Keeping Catalyst was developed by Nikki-Universal and is distributed by Sojitz Machinery for use in vessel ventilation. Ships implementing this technology now qualify for the specific ClassNK ELW (FP) notation.
The players
ClassNK
This is a classification society based in Japan that provides certification and safety standards for maritime vessels.
Nikki-Universal
This company is a specialized developer of catalytic products used for industrial and commercial air quality management.
Sojitz Machinery
This organization acts as the primary distributor for the newly certified ethylene-removing catalyst technology.
The details
The catalyst is installed directly within the air circulation or ventilation infrastructure of refrigerated storage rooms. By actively reducing ethylene gas concentrations, the system prevents the accelerated ripening of perishables during transit.
Timeline
October 7, 2026: The certification of the catalyst system was announced.
Culture Shift
This development follows the industry trend of adopting standardized preservation protocols under the ClassNK ELW (FP) notation. It reflects a broader shift toward reducing operational waste and improving resource management in maritime environments.
For maritime personnel, this technology means access to fresher produce throughout long voyages. It reduces the logistical reliance on resupplying perishables, potentially lowering food waste levels on participating commercial vessels.
The takeaway
Advancements in ethylene removal are proving critical for extending the usability of fresh inventory in isolated environments like shipping. Operators looking to minimize spoilage can now utilize certified hardware to maintain nutritional standards for crews during extended transit.
