Waste management involves the collection, transport, processing, disposal, and monitoring of waste materials. There are two main types of waste - solid waste like plastics and liquids like waste water. Wastes can also be classified as biodegradable, non-biodegradable, hazardous, or non-hazardous depending on their properties and effects. Sources of waste include households, commerce, industry, and agriculture. Improper waste management affects human health, the environment, and climate. The 3R approach of reduce, reuse, and recycle helps mitigate these issues. Philippine laws like RA 9003 promote responsible waste segregation, recycling, and disposal.

1. Waste
Management

2. Waste Management
• is the collection, transport,
processing or disposal,
managing and monitoring of
waste materials.

3. What are Wastes?
• “substances or objects which are disposed of or
are intended to be disposed of or are required to
be disposed of by the provisions of the law”
• a pejorative term for unwanted materials
Disposal means
• the action or process of throwing away or
getting rid of something
Manage means
• the act of controlling over something

4. Kinds of Wastes
• Solid wastes: domestic, commercial and industrial
wastes especially common as co-disposal of wastes
Examples: plastics, styrofoam containers, bottles,
cans, papers, scrap iron, and other trash
• Liquid Wastes: wastes in liquid form
Examples: domestic washings, chemicals, oils, waste
water from ponds, manufacturing industries
and other sources

5. Classification of Wastes
according to their
Properties
• Bio-degradable
- can be degraded (paper, wood, fruits and
others)
• Non-biodegradable
- cannot be degraded (plastics, bottles, old
machines, cans, styrofoam containers and others)

6. Classification of Wastes
according to
their Effects on Human
Health and the Environment
• Hazardous wastes
Substances unsafe to use
commercially, industrially, agriculturally, or economically that are
shipped, transported to or brought from the country of origin for
dumping or disposal in, or in transit through, any part of the
territory of the Philippines
• Non-hazardous
Substances safe to use
commercially, industrially, agriculturally, or economically that are
shipped, transported to or brought from the country of origin for

7. Sources of Wastes
Households
Commerce and Industry

8. Sources of Wastes
Agriculture
Fisheries

9. EFFECTS OF WASTE…
• Affects our health
• Affects our socio-economic conditions
• Affects our coastal and marine environment
• Affects our climate
According to NAS:
• Some countries are expected to become warmer,
although sulfates might limit warming in some areas.
• Scientists are unable to determine which parts of those
countries will become wetter or drier, but there is likely to
be an overall trend toward increased precipitation and
evaporation, more intense rainstorms, and drier soils.
• Whether rainfall increases or decreases cannot be
reliably projected for specific areas.

10. 3R’S
• RECYCLE - processing of used materials
or waste into a new product.
Ex. Recycling a paper
• REUSE – the item is used again in the
same function.
Ex. Reusing envelops, donating toys to
charity and use rechargeable batteries.
• REDUCE – to make something smaller.

11. Waste Generation by Country
(Global Waste Survey Final Report Published by IMO 1995)*

12. Waste Generation in the
Philippines
In Metro Manila:
• It is estimated that 25 million m3 of acid and
alkaline liquid waste is disposed of annually from
the electronics industry.
• Almost 2,000 m3 of solvents and 22,000 tonnes of
heavy metals, infectious wastes, biological
sludges, lubricants and intractable wastes are
disposed of on land or into water courses.
• 4,000 tonnes of solid wastes are generated daily.
Of these, only about 3,400 tonnes are collected
and transported to existing sites.

16. Compendium of the Social Doctrine
of the Church
Chapter Ten: SAFEGUARDING THE ENVIRONMENT
466. Care for the environment represents a challenge for all of
humanity. It is a matter of a common and universal duty, that of
respecting a common good,[979] destined for all, by preventing
anyone from using "with impunity the different categories of beings,
whether living or inanimate - animals, plants, the natural elements -
simply as one wishes, according to one's own economic needs".
Responsibility for the environment, the common heritage of
mankind, extends not only to present needs but also to those of the
future. "We have inherited from past generations, and we have
benefited from the work of our contemporaries: for this reason we
have obligations towards all, and we cannot refuse to interest
ourselves in those who will come after us, to enlarge the human
family".[984] This is a responsibility that present generations have
towards those of the future,[985] a responsibility that also concerns
individual States and the international community.

17. Compendium of the Social Doctrine
of the Church
Chapter Ten: SAFEGUARDING THE ENVIRONMENT
468. Responsibility for the environment should also find adequate
expression on a juridical level. It is important that the international
community draw up uniform rules that will allow States to exercise
more effective control over the various activities that have negative
effects on the environment and to protect ecosystems by preventing
the risk of accidents. "The State should also actively endeavour
within its own territory to prevent destruction of the atmosphere and
biosphere, by carefully monitoring, among other things, the impact of
new technological or scientific advances ... [and] ensuring that its
citizens are not exposed to dangerous pollutants or toxic
wastes".[986]
