Contribution Of Anhydrous Milk Fat To Environmental ‎impacts Generated By The Dairy Processing ‎

Authors : Younsi F .

Abstract

Milk constitutes an important ingredient in the Algerian ‎population diet. it is obtained by recovering process from milk ‎powder or the recombination-based milk powder and anhydrous ‎milk fat (AMF). These are the two main processes in place in ‎Algerian dairies. In this study, carried out in a dairy processing ‎situated in Boudouaou (Algiers), a comparative analysis of these ‎two processes was conducted in order to determinate the ‎contribution to environmental impacts of different basic elements ‎of manufacturing milk. The approach used was based on the life ‎cycle assessment (LCA), which is a standardized method (ISO ‎‎14040-14044). Results showed that the milk powder is the main ‎hot spot in almost all the categories under assessment. ‎Furthermore, adding the AMF has allowed the reduction of all ‎impacts of the order of 3 to 6% resulting in a decrease of 4.74 E-‎‎02 kgCO2eq of Global Warming Potential, 0.21MJ of the ‎consumption of non-renewable energy, a reduction of 2.60 E-‎‎03kg SO2eq for terrestrial acidification/nitrification potential. A ‎decrease of 0.16kg TEGsoil is recorded to terrestrial ecotoxicity ‎and 2.80 E-05kg PM2.5eq to respiratory inorganics.‎
