1)
Material resources related to supply of energy to site are not considered.
2) Covers all resources procured during the life cycle by Sulzer, including the oil used to operate the pump.
3)
Machining during the manufacturing produces recyclable waste of around 4% by mass of the metals bought in.
4)
In manufacturing: used for testing purposes.
