It is easy to overlook the environmental impacts of our food because it is spread across different varieties of species. From plants to animals, from production to transportation, from hunting to growing food, all of these have big impacts on the world today. How does dairy production effect the environment? Why is milk processed? Milk is a nutritious food that has a short shelf-life and needs to be handled carefully. Milk is highly perishable because it is an excellent place for the growth of microorganisms, mostly bacterial pathogens. These pathogens can cause spoilage and diseases. Milk processing conserves milk for days, weeks or months and it also helps to reduce food-borne illness (Food and Agriculture Organization of the United Nations 2016). The majority of milk is thermally processed at least once during its manufacture. Energy input and the increased resources needed to clean the spoiled heat exchangers are major parts of this process and the remaining plant processing equipment. Cleaning also has an impact on energy use and waste generation. Using more chemicals in the cleaning process increases the global waste production, but makes it less costly and takes less time to clean it. The manufacture of polyethylene or aluminum for packaging is the cause of the highest solid waste in the raw material production stage. Water use is seen as both the consumption and quality of waste and
