Every year, AVR (Waste Processing Rotterdam) converts 400,000 tonnes of waste into 127,000 MWh of electrical energy that is then supplied to the public electricity grid. In order to be able to process this enormous mountain of waste , 110 people work 24 hours a day, 7 days a week. There must be no failure of the incineration lines, which is why AVR Rotterdam called in PDM to radically professionalize their integral maintenance process. PDM defined four sub-projects that were completed in a period of 1 year, namely optimizing work-flow management, defining the job of Maintenance Engineering, analyzing the shutdown organization and associated processes, and setting up a management system and organization.
