Quezon City Controlled Disposal Facility Biogas

Emission Reduction Project


The project, which aims to reduce methane emissions from the Payatas controlled dumpsite, involves the capture, collection, processing, and flaring of landfill gas (LFG), including the coversion of methane into electricity. LFG is created by the decomposition of solid waste in the landfill. This gas is made up of about 50% methane, a greenhouse gas over 20 times more potent by weight than carbon dioxide (CO2).

The Quezon City government, in its desire to mitigate pollution and safeguard the health of its constituents, particularly those residing in the immediate area of the Payatas dumpsite, granted PGEP the rights to the biogas for a minimum of 10 years in exchange for PGEP's investment in the project. The memorandum of agreement was signed on February 14, 2007 and on February 1, 2008, the project was registered as a Clean Development Mechanism (CDM) project by the executive board of the United Nations Framework Convention for Climate Change (UNFCCC).

On March 2008, the biogas plant was commissioned. PGEP developed, financed, designed, constructed, and is presently operating the project activity. The first Certified Emission Reduction (CER) units equivalent to 30,860 were issued on June 25, 2009 for the first monitoring period from March 2008 to August 2009.



  • Biogas emissions are considered as health, safety, and environmental hazards
  • Emissions damage the vegetation
  • The main composition, methane, is a greenhouse gas that has a global warming potential of over 20 times that of carbon dioxide


  • Elimination or reduction of explosion and fire hazards, reduction of odor and ground water pollution, reduction of damage to existing vegetation, improvement of stability of dumpsite through removal of voids and perched leachate
  • Generation of employment and additional financial resources for Quezon City, Philippines
  • Capacity building of local stakeholders through education and training
  • Supply of green energy that electrifies the plant, street lights, and perimeter lights of the dumpsite
  • Reduction of greenhouse gas emissions (estimated emission reduction of over 100,000 CO2 tons per year)
