DOST's Water Hyacinth Harvester
Engineers from the Department of Science and Technology, lead by Engr. Lemuel Apusaga of Metals Industry Research and Development Center, have developed a water hyacinth harvester to speed up the removal of the fast-growing aquatic plant water hyacinths commonly known as water lilies which partly blamed for flooding in the areas of Pasig, Taguig and Province of Rizal.
In 2011, the water hyacinths were largely blamed for the clogging of the Rio Grande de Mindanao causing floods in the area. DOST Secretary Mario Montejo conceptualized the idea of developing a machine to solve this issue. He was also mentioned in an interview that DOST is looking at building ten more water hyacinth harvester.
Water hyacinth, aside from causing floods, can also be the cause of the killings of underwater plants and eventually fishes and aquatic life forms because it prevents the sunlight from penetrating into the water.
