HAZARDOUS WASTES, REPEALING FOR THE PURPOSE SECTION 20 OF 
REPUBLIC ACT NO. 8749, OTHERWISE KNOWN AS PHILIPPINE CLEAN AIR 
ACT OF 1999
EXPLANATORY NOTE
Since the enactment of Republic Act No. 9003 (RA 9003) or the Ecological Solid 
Waste Management Act of 2000, solid waste generation has steadily increased instead 
of its goal of reducing the same.1 In 2020, at least 16.63 million metric tons of solid 
waste was reported, with recent data showing that the daily average amounts to 
61,000 metric tons of solid waste generated, 24% of which are said to be plastic 
wastes.2 These statistics clearly show the frail enforcement of our current laws.
With the overwhelming amount of solid wastes generated, existing landfills are 
now at the brink of exceeding their capacities. In order to successfully address the 
waste management problem, there must be strong policies in place, supported by a 
national commitment both by the government and its people, with adherence to the 
highest standard form of discipline possible.
Incineration involves burning waste in specially designed furnaces at 
temperatures exceeding 850°C. This thermal treatment efficiently converts waste into 
thermal energy thus reducing landfill dependency and recovering usable energy for

consumption.3 Although there are serious environmental concerns about incineration, 
advances in emission control designs, along with strict standards and monitoring 
systems have caused large reduction of pollution in the atmosphere. In fact, both 
Singapore and Sweden, as well as other countries, have successfully used this process 
in addressing their waste management problems. Singapore's Tuas Incineration Plant, 
with a capacity of 3,200 tons/day, has not only generated 80 MW of electricity but has 
also integrated advanced fuel gas cleaning and ash recycling systems, representing 
a holistic approach to waste management and energy recovery. While for Sweden, 
more than 50% of its municipal solid waste goes through incineration. The Okhia 
Waste-to-Energy (WTE) Plant, in Delhi, India, incinerates approximately 1,500 tons of 
municipal solid waste per day, generating around 16 MW of electricity.4
The incineration process involves four vital stages: drying, pyrolysis, 
combustion, and post-combustion. Each stage plays a critical role in ensuring that 
waste is transformed efficiently with minimal emissions. The post-combustion stage is 
the most essential stage for meeting emission regulations and protecting air quality. 
Modern incineration plants utilize emission control systems, like electrostatic 
precipitators and scrubbers to remove particulates, dioxins, and sulfur oxides, ensuring 
compliance with current environmental standards. Recent developments in resource 
recovery from WTE residues allow recycling of metals and, in the case of sewage 
sludge, even phosphorus by thermal recycling. Combined with carbon capture and 
storage technology, WTE stands for a quantifiable contribution to greenhouse gas 
reduction. This is indispensable to reach the goals of circular economy, namely 
recycling of energy and materials, supplying safe final sinks for persistent organic 
substances and minimizing the need for sinks for hazardous inorganic substances.5
The ban on incineration was premised on the need to reduce the release of 
greenhouse gases like carbon dioxide (C02), methane, sulfur dioxide (S02) and 
nitrous oxide (N02) which bring about global warming and induce climate change. 
However, both landfill and the combustion of untreated mixed waste will release

carbon into the atmosphere, in different amounts. Landfill produces roughly equal 
amounts of carbon dioxide and methane, whereas energy from waste only produces 
carbon dioxide. As methane is around 25 times more damaging to the atmosphere, it 
is considered that WTE has a less detrimental impact on the environment overall.6
Republic Act No. 8749 (RA 8749) or the Philippine Clean Air Act of 1999 closed 
the option to safely and neatly dispose of municipal solid wastes by incineration which 
can generate electricity, targeting the two existing problems of our country; garbage 
and energy. With the latest trends and updates in the process of incineration, it is 
deemed to be a more feasible solution to the looming problem of waste management. 
The Supreme Court even pronounced in the case of Metro Manila Development 
Authority v. JANCOM Environmental Corporation (G.R. No. 147465, January 30,2002) 
that the Philippine Clean Air Act of 1999 does not absolutely prohibit incinerators as a 
mode of waste disposal "rather only those burning processes which emit poisonous 
toxic fumes are banned."
This bill seeks to repeal RA 8749 and lift the blanket prohibition on the use of 
incinerators in the disposal of solid wastes in the country. The proposed measure also 
aims to promote the use of recent advances in WTE technology, providing for the safe 
disposal of wastes without the harmful emissions to the atmosphere. Finally, the bill 
sustains the primacy of using non-burn technologies or ZeroWaste paths in waste 
disposal, such as recycling and waste segregation, as mandated by RA 9003.
In view of the foregoing, the immediate approval of this measure is earnestly
sought.
