Cold has been used to preserve foodstuff since long ago.
Today, we also expect a cleaner cold chain.
What I think is particularly interesting with OLIVO insulated containers is that this is a cold chain solution that uses little energy and is harmless.
The cold chain is a major concern in the field of human food supplies and using simple, reasoned means to maintain the cold chain during transportation is good for all of us and for the planet.
OLIVO also takes back the insulated containers once they are no longer usable ans recycles the material and components.
