CLARK FREEPORT —- The Metro Clark Waste Management Corp. (MCWM) has underscored the importance of building quality, engineered sanitary landfills in tackling the country’s growing waste problem.

In a media briefing at the Clark Freeport, the operator of Kalangitan Sanitary Landfill, the Philippines’ first engineered sanitary landfill, noted how open and uncontrolled dumping remains prevalent across the archipelago.

“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 chief executive officer Rufo B. Colayco said.

Citing data from the National Solid Waste Management Commission, Colayco disclosed that 403 open and 108 uncontrolled dumpsites continued to operate across the country while less than 15% of local government units had access to 118 sanitary landfills in 2016.

“We need more engineered sanitary landfills across the country,” Colayco said. “We have to ensure they conform to the highest standards and actually serve their purposes.”

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.

“We hope to set the bar high for waste management in the Philippines through our world-class engineered sanitary landfill within the Clark Freeport Zone,” Colayco said.

MCWM operates the Clark Integrated Waste Management Facility located within the Clark Freeport Zone. It is the first engineered sanitary landfill in the Philippines and one of the first in Asia to receive ISO certification.

Partly owned by German conglomerates BN Ingenieure GmbH and Heers & Brockstedt Umwelttechnik GmBH, the facility is patterned after the engineered sanitary landfills of Germany, a world leader in waste management.

It has multiple layers of liners, including a 2.5-millimeter high-density polyethylene material that exceeds Philippine standards. It also includes a leachate collection and treatment system; gas recovery system; materials recovery facility; and environmental buffer.

“We can only build as many sanitary landfills,” Colayco noted. “As our population continues to grow and our economy expands further, we need to find more ways to reduce the increasing volume of our waste.”

Colayco cited the experience of Germany and other European countries, where waste are turned into an energy source, among others.

“Let us take advantage of the existing waste management solutions that help us take a significant step forward to our ultimate goal: to preserve our environment for the future generations and ourselves,” Colayco said.
