C. Presenting instances
of the new lesson
Waste management is the collection, transport, processing, recycling or disposal of
waste materials. Waste Management program helps manage hazardous chemical,
radioactive, medical and other wastes safely and legally.
Types of Waste
Waste includes all items that people no longer have any use for, which they either intend
to get rid of or have already discarded. Many items can be considered as waste like
household rubbish, sewage sludge, wastes from manufacturing activities, packaging
items, discarded cars, old televisions, garden waste, old paint containers and others. Thus,
all our daily activities can give rise to a large variety of different wastes arising from
different sources.
Activity:
Identify the following pictures if it is a solid waste or liquid waste.
A. Solid wastes
Solid waste is defined as any waste that is dry in form and is discarded as unwanted. It
can describe the solid waste from general housekeeping as residential waste, refuse,
household waste or domestic waste.
Examples are plastics, Styrofoam containers, bottles, cans, papers, scrap iron, and other
trashes.

B. Liquid Wastes
Liquid waste includes human waste, runoff (storm water or flood water), sullage,
industrial wastewater and other forms of wastewater from different sources.
Examples are chemicals, oils, waste water from ponds.

D. Discussing new
concepts and practicing
new skill #1
Classification of Wastes According to their Properties
A. Bio-degradable
Biodegradable wastes are those that can be broken down (decomposed) into their
constituent elements by bacteria and other microorganisms. The term can be applied to
both liquid and solid waste. Examples are Human and animal wastes, food waste, paper,
and agricultural wastes.
B. Non-biodegradable
Non-biodegradable trash is any discarded item that cannot be broken down by living
organisms. Non-biodegradable trash accumulates in the environment because it cannot
return to its origins. Examples are plastics, bottles, old machines, containers and others.
Classification of Wastes According to their Effects on Human Health and the
Environment
A. Hazardous wastes – are unsafe substances used commercially, industrially,
agriculturally, or economically. Examples are paint, motor oil, pesticide, drain opener,
prescription drugs, air fresheners, batteries.
How should you handle medical wastes brought by CoVid-19? What are the examples of
hazardous healthcare wastes?
(video flashed on screen)
B. Non-hazardous – are safe substances used commercially, industrially, agriculturally, or
economically. Examples are papers, cardboard, linings, wrappings, paper packaging
materials or absorbents.
E. Discussing new
concepts and practicing
new skill #2
Process Flow of Waste Management
The process flow refers to the 3 (or 4) Rs of reduce, reuse, recycle, and recover which
classify waste management strategies according to their desirability. The Rs are meant to
be a hierarchy, in order of importance. However, the waste hierarchy has 5 steps: reduce,
reuse, recycle, recovery, and disposal.
Reduce - to buy less and use less.
Reuse - elements of the discarded item are used again.
Recycle - discards are separated into materials that may be incorporated into new
products.
Recover - capturing useful material for waste to energy programs.
Group Task
Classify the following recyclable and waste materials in the boxes
under each process flow.
Plastic Bags
Paper bags
Old clothes
Batteries
Glass Bottles
Paper wrappers
Candy Wrappers

Cans
Paper Wrappers
Left Over

Why is waste management important?
(Answer may vary)
Waste management is important because many natural resources such as trees, gas, and
water are depleting. For instance, paper, cupboards, paper cups, and many other
products that we use daily are made from trees. Huge areas of trees are cut down every
year, and new trees do not have enough time to fully grow. Fortunately, it is possible to
recycle paper products instead of cutting down new trees. Reforestation can only do so
much.
What are the 4Rs?
Reduce - to buy less and use less.
Reuse - elements of the discarded item are used again.
Recycle - discards are separated into materials that may be incorporated into new
products.
Recover - capturing useful material for waste to energy programs.
I. Evaluating learning
Determine the best method of waste management for each situation.
1. What method are you practicing when you lessen the amount of garbage at home?
Answer: Reduce
2. What method are you going to do if you want to use again the box container for your
papers?
Answer: Reuse
3. What method are you practicing when you create a lantern decoration out of plastic
spoons?
Answer: Recycle
4. You want to dispose some glass bottles because you cannot use it anymore. What
method are you going to do if you want to bring the glass to a recovery facility?
Answer: Recover
5. What method are you using when you are restoring or replacing a broken part of a
material?
Answer: Repair
J. Assignment
State the importance of having contingency plan for an emergency case.
