In addition to meeting customer requirements and maintaining competitiveness, enterprises must now include social responsibility in their strategy, with particular emphasis on ecology. This trend is partly forced by changes in environmental protection regulations, including waste management. For many enterprises this may mean the need to introduce changes in the production systems. One of such companies is B. Recycling sp. z o. o., producing concentrate of zinc oxide. Adaptation to current standards required a thorough modernization of the technological lines used, so that the zinc-bearing waste, storing which brings a threat to water resources, could be used as batch material in the rolldown process. The rolldown process implemented in the company is technologically complex and any deviation from the discipline may result in a lesser quality product and a significant increase in the number of unscheduled stops, and thus a drop in productivity. Because of that, the modernization was also aimed at improving the efficiency of the production system. The article describes the conducted process analysis, the purpose of which was to determine whether the changes made have led to the desired effect and identifying the areas with the greatest improvement potential. The elements of the TPM method were chosen as the research method. After collecting the time and quality data, MTTR, MTBF and OEE indicators were determined for each of the modernized lines and selected subassemblies. One of the analysis results was the proposition of a solution which would shorten the duration of the failure once applied.Keywords: Exploitation, zinc concentrate, TPM method, OEE
