San Miguel Corp.'s (SMC) massive environment sustainability and flood mitigation initiative to clean up the 27-kilometer Tullahan River system shifts to higher gear in December, as the company is set to acquire additional new equipment to double its solid waste extraction capacity to 5,000 metric tons (MT) per day.

SMC President Ramon S. Ang said the company's commitment to clean up the Tullahan river system – ranked No. 4 in the list of the world's top 10 plastic-emitting rivers responsible for global ocean plastic pollution, according to a 2021 report by research website ourworldindata.org – is stronger than ever, as SMC has made the cleanup of major rivers one of its foremost sustainability priorities.
