International Activities (Pilot Countries) Serbia - Pilot projects

Project title Lubrication of PET packaging line Partners ChL service provider: Ecolab ChL service recipient: Knjaz Milos, mineral water producer Implementing agency: UNIDO- Cleaner Production Center of Serbia Industrial process Packaging of PET bottles Chemicals used Lubricant (Surface Active Material) Service provided under ChL The process is modified from wet lubrication (use of water and chemicals for lubrication) to dry lubrication. It was agreed that the unit of payment is number of working hours of the Conveyor. Benefits a. Environmental benefits Water is not used for the lubrication process (consumption will be reduced by1500 m3 yearly); Sodium hypochlorite is not used for water pretreatment for the line PET 3 (consumption of active chlorine will be reduced by 7.5 kg yearly, that means about 270 l of sodium hypochlorite); Consumption of chemicals for waste water treatment will be reduced (cannot be quantified as waste water treatment is done by Public Utility); The chemical for lubrication with dangerous characteristics is replaced with the eco friendly one; Consumption of the chemical for lubrication is three times less than before the ChL model implementation Even though there is some energy savings (electricity) that is negligible (there is no water pumping, spraying time and coefficient of friction are less). b. Economical benefits for Knjaz Milos The costs are calculated for 5000 working hours of the conveyor per year. Savings are around 6000 EUR yearly (only the costs of chemicals and water were calculated). c. Intangible benefits for Knjaz Milos Better coefficient of friction of the conveyor; The conveyor will last longer; Better line productivity (there is no dropped bottles); Higher cleaning standards - Microbiological problems are eliminated since water is not used any more; There is microbistatic effect in the lubrication and conveyor system due to the characteristic of the new chemical; Better occupational health and safety (reduced quantity of aerosols in the air, cleaner working environment, risk of injuries is significantly reduced, as the floor is not slippery; Reduced time and cost of cleaning and disinfection of the conveyor. d. Benefits for Ecolab Cost for transportation is three times lower, as the imported quantity is lower Cost for storage hiring is lower Services are the part of the product price Better relationship with user Threat from competitors is significantly reduced (before ChL model implementation, Knjaz Milos had two suppliers of a lubricant for this line).
