RATIONALE
 “What is waste?” This may be a
question kids like you may ask. Once you have
understood the concept of waste, then wonder
about how waste affects the environment and
how to properly dispose of it.
How else can we best promote proper waste
management to the future generation better than
by educating children about it? They say that
you children hold the key to our future and it is
our task to make sure that you are well-informed
and have the good of our society and the
environment in your minds.
What is waste?
What is waste (trash, garbage, rubbish, refuse)
Waste are items we (individuals, offices, schools,
industries, hospitals) don’t need and discard. Sometimes
there are things we have that the law requires us to
discard because they can be harmful. Waste comes in
infinite sizes—some can be as small as an old toothbrush,
or as large as the body of a school bus.
Types of Wastes
Generally, waste could be liquid or solid waste. Both of
them could be hazardous. Liquid and solid waste types
can also be grouped into organic, re-usable and
recyclable waste.
1. Liquid type:
Waste can come in non-solid form. Some solid waste can
also be converted to a liquid waste form for disposal. It
includes wastewater. Examples of liquid waste include
wash water from homes, liquids used for cleaning in
industries and waste detergents.
2. Solid type:
Solid waste predominantly, is any garbage, refuse or
rubbish that we make in our homes and other places.
These include old car tires, old newspapers, broken
furniture and even food waste. They may include any
waste that is non-liquid.
3. Hazardous type:
Hazardous or harmful waste are those that potentially
threaten public health or the environment. Such waste
could be flammable (can easily catch fire), reactive (can 
easily explode),corrosive (can easily eat through metal) 
or toxic (poisonous to human and animals).
–
4. Organic waste comes from plants or animals sources.
Commonly, they include food waste, fruit and vegetable
peels, flower trimmings and even dog poop can be
classified as organic waste. They are biodegradable (this
means they are easily broken down by other organisms
over time and turned into manure). Many people turn
their organic waste into compost and use them in their
gardens.
5. Recyclable type:
Recycling is processing used materials (waste) into
new, useful products. This is done to reduce the
use of raw materials that would have been used.
Waste that can be potentially recycled is termed
"Recyclable waste". Aluminum products (like soda,
milk and cans), Plastics (grocery shopping bags,
plastic bottles), Glass products (like wine and beer
bottles, broken glass), Paper products (used
envelopes, newspapers and magazines, cardboard
boxes) can be recycled and fall into this category.
SOURCES OF WASTES
 1. Medical/Clinical sources of waste:
Medical/clinical waste, normally refers to waste produced
from health care facilities, such as hospitals, clinics,
surgical theaters, veterinary hospitals and labs. They tend to
be classified as hazard waste rather than general waste.
 Items in this group include surgical items, pharmaceuticals,
blood, body parts, wound dressing materials, needles and
syringes
 2. Agricultural sources of waste:
Typically, this is waste generated by agricultural activities.
These include horticulture, fruit growing, seed growing,
livestock breeding, market gardens and seedling nurseries.
 Waste items in this group include empty pesticide
containers, old silage wrap, out of date medicines and
wormers, used tires, surplus milk, cocoa pods and corn
husks.
 3. Industrial sources of waste:
Since the industrial revolution, the rise in the number of
industries manufacturing glass, leather, textile, food,
electronics, plastic and metal products has significantly
contributed to waste production. Take a look at the things in
your home, every item there was probably manufactured and
possibly, waste was produced as a result.
 4. Construction/demolition sources of waste:
Construction waste is that resulting from the construction of
roads and building. Sometimes old buildings and structures
are pulled down (demolished) to make space for new ones.
This is particularly common in old cities that are
modernizing. This is called demolition waste.
 Waste items include concrete debris, wood, earth, huge
package boxes and plastics from the building materials and
the like
 5. Electronic sources of waste:
This is waste from electronic and electrical devices.
Think of DVD and music players, TV, Telephones,
computers, vacuum cleaners and all the other
electrical stuff in your home. These are also called e-
waste, e-scrap, or waste electrical and electronic
equipment (WEEE)
Some e-waste (like TV) contains lead, mercury,
cadmium, and brominated flame retardants. These
are harmful to humans and the environment. It is
therefore important that the right authorities ensure
the proper disposal of such waste.

Effects of waste and poor waste
disposal
Environmental Effects
Surface water contamination:
Waste that end up in water bodies negatively change the
chemical composition of the water. Technically, this is called
water pollution. This will affect all ecosystems existing in the
water. It can also cause harm to animals that drink from such
polluted water.
Soil contamination:
Hazardous chemicals that get into the soil (contaminants) can
harm plants when they take up the contamination through their
roots. If humans eat plants and animals that have been in
contact with such polluted soils, there can be negative impact
on their health.
Pollution:
Bad waste management practices can result in land and air
pollution and can cause respiratory problems and other adverse
health effects as contaminants are absorbed from the lungs into
other parts of the body. (Pollution is fully covered here)
 Efficient and effective waste management is best
achieved at household levels.
If every person gets involved, we can have a powerful
effect on the our environment in a positive way.
Many times, people want to do the right things but they
feel they are alone, and their actions will not make any
difference — Wrong!!
There are millions of great teens like you who
appreciate the magnitude of the waste problem and are
doing the right things to help. But we can do more and
get others who are not doing well to do better.
PLAY YOUR PART!

R ------- RE – THINKING
HERE’S WHAT KIDS CAN DO!
 Reduce creating waste
The next time you change the waste-bin bag, take a look
inside it. Is there anything that could have not ended up
there? Probably. Try cutting the waste you produce at
home into half. For example,
Use proper towels and ceramic plates at home instead of
paper towels, disposable spoons and paper plates.
Get your own shopping bag instead of bringing home
plastic bags each time you go grocery shopping.
Use old post package boxes to send parcels instead of
buying new ones.
Re-use things that end up as waste
There are things that can be used over and over again:
package boxes, gift wrappers, clothing, furniture and even
playing toys. If even you have outgrown them, you can give
it out to someone who has a need for it. Do not be too
quick to throw them away.

CSIW ZERO WASTE MANAGEMENT

  • 1. WASTE MANAGEMENT FOR KIDS BY: WILFREDO D. BARTOLO, JR. TEACHER III MUNICIPAL SCIENCE COORDINATOR Republic of the Philippines DEPARTMENT OF EDUCATION Region XII Division of Cotabato MLANG NATIONAL HIGH SCHOOL Mlang, Cotabato
  • 3. RATIONALE  “What is waste?” This may be a question kids like you may ask. Once you have understood the concept of waste, then wonder about how waste affects the environment and how to properly dispose of it. How else can we best promote proper waste management to the future generation better than by educating children about it? They say that you children hold the key to our future and it is our task to make sure that you are well-informed and have the good of our society and the environment in your minds.
  • 4. What is waste? What is waste (trash, garbage, rubbish, refuse) Waste are items we (individuals, offices, schools, industries, hospitals) don’t need and discard. Sometimes there are things we have that the law requires us to discard because they can be harmful. Waste comes in infinite sizes—some can be as small as an old toothbrush, or as large as the body of a school bus.
  • 5. Types of Wastes Generally, waste could be liquid or solid waste. Both of them could be hazardous. Liquid and solid waste types can also be grouped into organic, re-usable and recyclable waste. 1. Liquid type: Waste can come in non-solid form. Some solid waste can also be converted to a liquid waste form for disposal. It includes wastewater. Examples of liquid waste include wash water from homes, liquids used for cleaning in industries and waste detergents.
  • 6. 2. Solid type: Solid waste predominantly, is any garbage, refuse or rubbish that we make in our homes and other places. These include old car tires, old newspapers, broken furniture and even food waste. They may include any waste that is non-liquid. 3. Hazardous type: Hazardous or harmful waste are those that potentially threaten public health or the environment. Such waste could be flammable (can easily catch fire), reactive (can  easily explode),corrosive (can easily eat through metal)  or toxic (poisonous to human and animals). –
  • 7. 4. Organic waste comes from plants or animals sources. Commonly, they include food waste, fruit and vegetable peels, flower trimmings and even dog poop can be classified as organic waste. They are biodegradable (this means they are easily broken down by other organisms over time and turned into manure). Many people turn their organic waste into compost and use them in their gardens.
  • 8. 5. Recyclable type: Recycling is processing used materials (waste) into new, useful products. This is done to reduce the use of raw materials that would have been used. Waste that can be potentially recycled is termed "Recyclable waste". Aluminum products (like soda, milk and cans), Plastics (grocery shopping bags, plastic bottles), Glass products (like wine and beer bottles, broken glass), Paper products (used envelopes, newspapers and magazines, cardboard boxes) can be recycled and fall into this category.
  • 9. SOURCES OF WASTES  1. Medical/Clinical sources of waste: Medical/clinical waste, normally refers to waste produced from health care facilities, such as hospitals, clinics, surgical theaters, veterinary hospitals and labs. They tend to be classified as hazard waste rather than general waste.  Items in this group include surgical items, pharmaceuticals, blood, body parts, wound dressing materials, needles and syringes  2. Agricultural sources of waste: Typically, this is waste generated by agricultural activities. These include horticulture, fruit growing, seed growing, livestock breeding, market gardens and seedling nurseries.  Waste items in this group include empty pesticide containers, old silage wrap, out of date medicines and wormers, used tires, surplus milk, cocoa pods and corn husks.
  • 10.  3. Industrial sources of waste: Since the industrial revolution, the rise in the number of industries manufacturing glass, leather, textile, food, electronics, plastic and metal products has significantly contributed to waste production. Take a look at the things in your home, every item there was probably manufactured and possibly, waste was produced as a result.  4. Construction/demolition sources of waste: Construction waste is that resulting from the construction of roads and building. Sometimes old buildings and structures are pulled down (demolished) to make space for new ones. This is particularly common in old cities that are modernizing. This is called demolition waste.  Waste items include concrete debris, wood, earth, huge package boxes and plastics from the building materials and the like
  • 11.  5. Electronic sources of waste: This is waste from electronic and electrical devices. Think of DVD and music players, TV, Telephones, computers, vacuum cleaners and all the other electrical stuff in your home. These are also called e- waste, e-scrap, or waste electrical and electronic equipment (WEEE) Some e-waste (like TV) contains lead, mercury, cadmium, and brominated flame retardants. These are harmful to humans and the environment. It is therefore important that the right authorities ensure the proper disposal of such waste. 
  • 12. Effects of waste and poor waste disposal Environmental Effects Surface water contamination: Waste that end up in water bodies negatively change the chemical composition of the water. Technically, this is called water pollution. This will affect all ecosystems existing in the water. It can also cause harm to animals that drink from such polluted water. Soil contamination: Hazardous chemicals that get into the soil (contaminants) can harm plants when they take up the contamination through their roots. If humans eat plants and animals that have been in contact with such polluted soils, there can be negative impact on their health. Pollution: Bad waste management practices can result in land and air pollution and can cause respiratory problems and other adverse health effects as contaminants are absorbed from the lungs into other parts of the body.

  • 13.  Efficient and effective waste management is best achieved at household levels. If every person gets involved, we can have a powerful effect on the our environment in a positive way. Many times, people want to do the right things but they feel they are alone, and their actions will not make any difference — Wrong!! There are millions of great teens like you who appreciate the magnitude of the waste problem and are doing the right things to help. But we can do more and get others who are not doing well to do better. PLAY YOUR PART!

  • 15. HERE’S WHAT KIDS CAN DO!  Reduce creating waste The next time you change the waste-bin bag, take a look inside it. Is there anything that could have not ended up there? Probably. Try cutting the waste you produce at home into half. For example, Use proper towels and ceramic plates at home instead of paper towels, disposable spoons and paper plates. Get your own shopping bag instead of bringing home plastic bags each time you go grocery shopping. Use old post package boxes to send parcels instead of buying new ones. Re-use things that end up as waste There are things that can be used over and over again: package boxes, gift wrappers, clothing, furniture and even playing toys. If even you have outgrown them, you can give it out to someone who has a need for it. Do not be too quick to throw them away.
