NanoFreeze: Cool Innovation in Cold Transportation Could Counter Climate Change
A revolutionary refrigeration method, which uses a novel bio-nanotechnology able to freeze at higher temperatures, could slash the energy use and carbon footprint of the cooling industry by half.
That’s the claim of NanoFreeze, which created its bio-nanotechnology as a university project in the bio-design field in 2018. Its first product application was a portable cooler to bring refrigerated items to remote areas, and went on to be the overall winner of the BioDesign Challenge 2019 in New York against universities such as Harvard and MIT.
Now the company aims to put the challenges of food waste at the heart of the cooling industry of the future. It states that its technology is a brand new way to refrigerate naturally, and can preserve the cold chain twice as long as regular frozen water.

Its coolant products like Ice Packs, Cool Coats, and Reusable Ice already adapt their cold chain technology to the needs of almost anything that requires refrigeration during transportation. An ice-like solid maintains food at a chilled 2ºC to 8ºC for up to 200 hours, and also acts as an insulator for a wide variety of cold chain products including Ice Packs, Coolers, Cold Coats, and Energy Savings Panels.
Currently these products are designed to sustain the cold chain for extended periods. NanoFreeze claims that its technology enables the products to retain cold without any energy input, helping to prevent food spoilage from cold chain disruption. NanoFreeze says that their coolers are fully recyclable and feature a biodegradable coolant, promoting sustainable cold transport.
The company says that it is collaborating with Colombian farmers exporting vegetables, herbs, and fruits, who report savings of over USD 320,000 in food waste within a year of employing Cold Coats during export. According to NanoFreeze, this has enabled agro-export clients to reduce food waste from an average of 30% down to a mere 5% or even zero.
NanoFreeze states that its panels could halve the energy consumption of refrigerators, small cold rooms, and shipping containers, marking a new era of sustainable innovation in cold transport.
