BAGUIO CITY: A low-cost and environmentally sound green technology through the use of plants is an emerging alternative means of getting rid of pollutants in contaminated land and water systems through the so-called phytoremediation.
Science Research Specialist II Randy S. Tubal said the phytoremediation technology has been gaining popularity and acceptance worldwide and is now also being used in various parts of the country including the Cordillera Administrative Region (CAR).
The United Nations Environment Programme defines phytoremediation as the direct use of living green plants for in situ, in place, removal, degradation, or containment of contaminants in soils, sludges, sediments, surface water and groundwater.
The technology works such that plants equipped with remarkable chemical processing and absorption capabilities as well as transport systems can take up nutrients or contaminants selectively either from soil and water, according to Tubal. The said green technology restores balance in the ecosystem and curbs stressed environment.
