Life Cycle Assessment: Life cycle assessment of a high speed centrifugal separator
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
The main objective is to perform a life cycle assessment (LCA) on a hot milk high-speed centrifugal separator (HMRPX 918-HGV-74C, product number 881275 01 01. The purpose of a life cycle assessment (LCA) is to provide a picture of a product’s total environmental impact during its lifecycle.
The study is carried out according to ISO 14 040, i.e. all methods, data and assumptions are accounted for in order to make an external review possible. An LCA could provide the basis for an Environmental Product Declaration (EPD).
The LCA clearly shows that the main environmental impact of the separator is caused by CIP and electricity used during operation. The major part of the impact from the CIP chemicals is due to the energy needed for their manufacture. Fossil fuels account for most of the impact for both operation and manufacture of chemicals. Therefore customers should be encouraged to use environmentally friendly electricity and chemicals, such as renewable energy sources and sodium hydroxide made with membrane technology. It is also important to use as little as possible of cleaning agents and make sure that waste is treated properly.
