Problem

In many developing countries, the rate of postharvest loss for fruits and vegetables exceeds 50 percent. Cool storage can greatly reduce these losses, increasing income for farmers.

Solution

ZECC cool chambers can reduce temperature by 10-15 C and maintain high humidity of about 95% that can increase shelf life and retain quality of horticultural produce. The ZECC is appropriate for on-farm storage as well as collection points.

Target Beneficiaries
