Government Develops Technology to Fight Pollution


The Department of Science and Technology (DoST) has developed a technology which can address air pollution problems from gold and silver refining plants.DoST Industrial Technology Development Institute (ITDI) Environment Division chief Dr. Christopher Silverio said they have developed the Wet and Dry Scrubbers for Gold and Silver Refining Plants. Scrubber systems are a diverse group of air pollution devices that could be used to remove some particulates and/or gases from individual exhaust streams.

A wet scrubber is used to clean air and other gases of various pollutants and dust particles while dry scrubbers are used to remove acid gases like sulfur dioxide primarily from combustion sources. The technology enables refining plants to control emissions, which is detriment to human health.


Prior to the local development of the said technology, residents near gold and silver refining plants, particularly in Bulacan, complains of pungent smell coming from refining plants, particularly from burning gold or silver. With the wet and dry scrubbers, refining plants may now have cleaner emissions art the scrubbers take off lead, nitric acid, copper and other impurities from producing gold and silver.
