Environmental legislation is becoming ever more strict. In the last 15 years the focus has shifted from reducing sulphur dioxide emissions to also reducing fine dust emissions. In 2009 the Dutch government required of Tata Steel to build new dedusting installations for its sinter plant, based on fabric filter technology. A small and integrated project team choose a smart configuration for the new filters. This paper describes the execution and implementation of projects in existing plants and organizations. It is concluded that the project implementation was excellent, mounting works at the site we restricted due to delivery of the new units as large-size components. All expenses on additional project points didn't exceed 0.1 % of total investments; such result has been achieved not only owing to the good buying contract, but also timely and close collaboration between sinter plant, rolling shop and building team. Multiple testings, control and preliminary planning (one year prior to the project realization) allowed to use optimally down-times for technical maintenance and to decrease maximally losses of operating time during putting into practice. The new dedusting system and waste gas cleaning unit provide correspondingly cutting dust emissions by 90 % and 85 %. At present time, SO₂ emissions meet the requirements used for wet gas cleaning.
