Growing waste problem in PH calls for more engineered sanitary landfills
Metro Clark Waste Management Corp. (MCWM), the operator of the Philippines’ first engineered sanitary landfill, underscored the importance of building quality, engineered sanitary landfills in tackling the country’s growing waste problem.
“The number of sanitary landfills in the Philippines remains small despite the passage of Republic Act No. 9003, which requires for the closure of open and uncontrolled dumpsites, about 17 years ago,” MCWM President and CEO Rufo Colayco said.
Citing data from the National Solid Waste Management Commission, Colayco said that 403 open and 108 uncontrolled dumpsites continued to operate across the country while less than 15 percent of local government units had access to 118 sanitary landfills in 2016.
“We need more engineered sanitary landfills across the country. We have to ensure they conform to the highest standards and actually serve their purposes,” Colayco said.
At the minimum, RA 9003 requires sanitary landfills to have liners; a leachate collection and treatment system; a gas control recovery system; groundwater monitoring well system; covers; closure procedure and post-closure procedure.
The environmental protection features aim to protect the air, soil and groundwater from contamination by leachate and other waste-related emissions.
