Life of a Milk Carton/Bottle
The process of my life as milk
The Beginning
Dairy cows don't start producing milk until they had their first calf. After that the dairy cows are milked twice a day. The milk travels through milking lines to the stainless steel pipes. The pipes then lead to refrigerated storage tanks and milk is cooled down to 4 degree Celsius.
Transportation
The trucks have large stainless steel refrigerated tanks that keep the milk cool during the transportation.
During the transportation, the truck emits CO2 into the air.
Testing and Storage
The milk then goes through a process called pasteurization: when the milk is heated and then cooled again to make sure that the milk is germ-free.
In order to make the milk more creamy and smooth it goes through the process of homogenization: the milk gets pushed through tiny holes which mixes the cream evenly into the milk
Afterwards the milk is put into storage again to be kept cool for packaging while some milk is processed further to make other dairy products.
Packaging
The End
We buy milk from supermarket and take it home.
