The Cold Chain Problem in Remote Regions
In rural Africa, Southeast Asia, and parts of Latin America,lack of cold storage leads to massive post-harvest lossesin agriculture and significant challenges for rural healthcare.
Common issues include:
-
Fruits and vegetables spoiling within 1–2 days
-
Fishermen unable to store catches for market
-
Vaccines and insulin degrading without temperature control
-
Diesel coolers being too expensive and unreliable
Asolar-powered cold storage systemoffers a sustainable alternative—especially when grid power is limited or unavailable.
