(RA 9003)
What are the 4Rs?
Reduction, Reuse, Recycling, Recovery
Ecological Solid Waste Management Act
(RA 9003)
- Ban open burning of solid waste
- Phase out open dumping; promote sanitary
landfill - Non-segregation of waste is illegal
- Phase out non-recyclable packaging materials
- Establish recycling centers
- Prepare 10-year SWM programs (LGUs)
REGULATE, RESTRICT or PROHIBIT the importation, manufacture, processing,
handling, storage, transportation, sale, distribution, use & disposal of all
unregulated chemical substances & mixtures that present unreasonable risk and/or
injury to health or the Philippine environment.
Toxic Substances and Hazardous Waste Management Act (RA 6969)
Toxic Wastes and Hazardous Management Act
- PROHIBITION of entry, transit, as well as
storage & disposal of hazardous & nuclear
wastes into the country - Promotes advancement in research studies regarding toxic chemicals.
- Bans incineration or burning of wastes
which emits poisonous & toxic fumes - Promotes non-burn technologies for
handling, treatment, thermal destruction, utilization, and disposal of sorted, un-
recycled, un-composted biomedical and hazardous waste
Clean Air Act of 1999 (RA 8749)
Clean Water Act of 2004 (RA 9275) (EVENTS)
- Pasig River pollution
- Marcopper Mining Disaster (Marinduque, 1994)
Clean Water Act of 2004 (AIM)
Aims to to protect water bodies from
pollution from land-based sources
(industries, commercial establishments,
agriculture & household)
- Provides for a comprehensive and
integrated strategy to prevent and minimize pollution through a multi- sectoral and participatory approach involving all the stakeholders
Clean Water Act of 2004
Water Quality Guidelines and General Effluent Standards (DAO 2016-08)
- Water body classification
- Determination of time trends
- Evaluation of stages of water quality enhancement/ deterioration
- Basis for taking positive actions for prevention, control, or abatement of water pollution
- Designation of water quality management areas
- Set the GES
Water Quality Guidelines and General Effluent Standards (DAO 2016-08)
- Revised Water Usage & Classification
- Revised Effluent Regulation
Water Quality Guidelines and General Effluent Standards (DAO 2016-08) (READ)
DAO 2021-19 is an UPDATE to DAO 2016-08:
This Order covers the updating of WQG and/or GES for the following parameters:
3.1 Ammonia as NH3-N
3.2 Boron
3.3 Copper as Dissolved Copper
3.4 Fecal Coliform
3.5 Phosphate as Phosphorus (Total, Reactive)
3.6 Sulfate
This also cover additional requirements on the use of GES for strong wastewater for BOD, requirements for modification of Significant Effluent Quality Parameter (SEQP), and amendment to Section 7.0 of DENR AO 2016-08.

Environmental science and environmental engineering
Specialized career fields that focus on
protecting the environment
Combines disciplines and methodologies
from the biological, information, chemical
and physical sciences to study the
environment and the impact from external
factors like urban development and
population growth
Environmental science
Focus on combining environmental science
methods with engineering principles to
develop and implement better
infrastructure, technology and industrial
operations that reduce the risk of
environmental contamination and pollution.
