Every year in India, over 18% of fruits and vegetables are wasted due to lack of cold storage. A food agency of the United Nations said that 40% of fruits and vegetables in India become unhealthy before reaching the people. There is a severe shortage of cold storage in India, while India is the second largest producer of fruits and vegetables in the world, as well as being an agricultural based country. In order to overcome the above losses, effective post-harvest storage infrastructure is required. Since cold storage is a power gulping monster and in order to develop the infrastructure for the same, large electric requirements needs to be addressed. It can be met by the conventional electricity production, but it will further increase our dependence on crude oil imports or it will have an impact on environment. By looking into the above scenario two different sustainable approaches are proposed. One of the approaches is of integrated vapor absorption system driven by bio-fuel based combustion chamber. Another approach is to run vapor absorption system on the waste heat rejected by the internal combustion (IC) engines powered by bio-fuels. Coefficient of performance (COP) based analysis has been done to determine the yearly requirements of different bio-fuels for meeting this requirement. On the basis of result obtained biodiesel is proposed for first model and biogas & ethanol is proposed for second system.
