CARBON FOOTPRINT OF MILK PROCESSING: A LIFE CYCLE BASED APPROACH

Vaibav, Genitha I. and John Diamond Raj

Abstract

This study was undertaken with the aim to assess and enumerate direct and indirect CO2 emissions from Student Training Dairy Plant, WSDT, using an LCA approach. One litre of milk was chosen to be the functional unit and the operations from milk reception to packaging were considered to be the system boundary for the research. The activity level for Life Cycle Inventory was collected by consulting the personnel at the plant and the data registries available at the plant and the emission factors for the various sources were taken from various international registries such as IPCC and NDRC. The results showed that the indirect emissions contributed the most to the overall carbon emissions, i.e., 19.675 KgCO2e. The LCIA showed the Global Warming Potential of Indirect emissions to be higher than direct emissions.
