Ayesa was responsible for the detailed design, procurement and construction supervision of the expansion. The existing plant remained operational during the works and this required close cooperation from all parties. A major concern for the client was to address odour issues due to the plant’s close proximity to the Swords community. Ayesa worked to alleviate the client’s concerns, modelling the odour impact and identifying appropriate mitigation measures. These included ensuring that all new processes were fully enclosed, with odour treatment provided on all extracts.
