Some of the actions taken were: major verticalisation, with integration of the production - from the cork to the bottle - making it possible to increase control of the process and traceability of the products; installation of modern industrial units, such as those of Coruche and Ponte de Sôr, that own extensive areas for storing cork, which substantially reduces the quantity of raw material stored in stacks in the forest, allowing greater control and reduction of the risk of TCA contamination; implementation of technologically advanced cork boiling systems: the two units mentioned above are equipped with stainless steel boiling systems with complete renewal of water at the end of coupled to filtering systems and systems to extract volatile trace compounds from the water, in a process that avoids cross contamination of cork planks from the water in which they are boiled; chromatographical analysis of TCA in all batches of corks, discs and granulates: after the presentation made by ETS Laboratories, in 2000, of the results of an R&D project to apply GC-MS SPME (Gas Chromatography Mass Spectrometry Solid Phase Microextraction) to quality control of batches of stoppers, discs and granulates, the Cork Stoppers BU has changed the quality control system for those batches, proceeding to use this methodology, having consistently increased the Amount of equipment.
