Implementation of life cycle assessment on production of Fresh Pasteurized Milk

Cow fresh milk is managed and milked by dairy farmers then it is collected at Cooperation of Milk Farmers Warga Mulya. It is processed to pasteurized fresh milk and packed in plastic cup of 160 ml. Whole activities are influenced by scale of ownership, type of milking process and energy use for conducting activities. The objective of this research was to implement Life Cycle Assessment (LCA) on fresh pasteurized milk production. Some parameters were considered; milking technique and number of cows at every farmers. The LCA is a method to calculate the environmental impact of fresh pasteurized milk production. The samples were 10 farmer members. The process was started from milking at farmers, picking up the fresh milk, receiving milk at Cooperation, then milk processing or pasteurization. All energy, waste and others were collected, calculated, analyzed and then determined into environmental effect category. The results showed, that the energy use for carrying out all activities was reached by 3.8284 MJ/l. The highest emission was gained by pasteurization process released 47.3869 g/l CO₂ equivalent, 0.0564 g/l SO₂; 0.4823 g/l NO_x and 0.0025 g/l CH₄. The highest impact to environment was contributed by pasteurization process as follow; Global Warming Potential (GWP) 87.6969 g CO₂ equivalent; Acidification Potential (AP) 1.6827 g SO₂ equivalent and Eutrophication Potential (EP) 0.7246 g NO_x- equivalent.
