QUARTER 1 MODULE 5 WEEK 5

DAY 1

Learning Competencies (Essential Competencies)

Design a product out of local, recyclable solid and/or liquid materials in making useful products.
(S5MT-Ih-i-4)

Objective
∙ Identify the 5Rs components: Reduce, Reuse, Recycle, Recover and Repair for
proper waste management.

Brief Introduction
Some human activities bring hazard to environment, especially waste materials. Most waste at home
are collected by garbage truck and disposed in Landfills. This piled up waste brings danger in the
environment especially land, air and water that causes Pollution. To minimize the waste in the
environment the environmentalist suggested the use of 5R`s.

Let’s Recall (Review)

Look at the picture carefully. Write HAZARD if the picture shows danger and
NO if not.

Let’s Understand (Study the Concept)

There are five (5) ways in segregating waste. All serve as help to lessen waste in
the environment.

Reduce – lessen the amount of waste in the environment. Use less material that are disposable.
Think and buy product that could be beneficial to human and environment.
Example: Instead of using sachet, use bigger pack or bottle which you can
 refill after.
Reuse – simply means to use it again or find a way to use the materials again.
Example: 1. Use an eco-bag when going to groceries or market instead of using plastic. 2.
Conduct garage sale to sell old stuff you are not using anymore. 3. Donate old stuff to help
people mostly in need it.
4. Use old clothes instead of buying new one.

1
Recycle – create new product from a material that serve its purpose already. The use of recycled
materials should be different from its old use, while minimizing waste in the environment and at home.
Another benefit of recycling we can conserve our natural resources. It can also prevent pollution by
reducing waste materials, we prevent habitat destruction of animals and other living things. You can use
also show your creativeness in recycling.
Here are some ways to recycle materials at home:
1. Buy rechargeable batteries not the one that you need to dispose after use. You save
environment you save money.
2. Buy materials that already recycles. Examples recycled notebooks,
papers, and others.
3. Make a recycling bin at home, and separate those waste that can be recycled.
4. Old clothes can turn into a shopping bag.
5. Old tires can turn into a swing hanging on trees, which can play by
kids, or can turn into a plants pot.
Repair – fixing or restoring broken materials for repurpose.
Example: Instead of throwing worn out clothes, sew it to use again.
Recover – it means taking of energy from waste materials which cannot be used
anymore. Most of the waste materials are segregated in a Materials Recovery Facilities
(MRF)
Example: Biodegradable waste can be put a compose pit to
serve as organic fertilizer.

during calamities.

RECYCLE
You already know what recycling is. In this lesson you will learn ways
how to recycle waste materials. 1.
There are two ways of recycling non- biodegradable materials it can be done
by Upcycling and Downcycling. Up cycling- is a way to make a higher
quality material from its original value. down cycling produces new product
with lesser quality. Recycling of non- biodegradable can be
done in two ways. Recycling biodegradable
Plastic bottles used as decorative pots
composting in backyard compose pits or indoor
materials can be done by
containers to produce Look inside your house. Find a material which you
compost. Use toilet papers, grass clippings, trash think can still be use. And answer the following. 1.
from garden plants can be recycled. A compost pit What material you found that you think still can be
can be made by digging a hole in the soil, in which
use?
biodegradable wastes can be thrown inside the hole
and then covered with layers of soil. After the
materials decay in a period it can be use as soil
fertilizer in the garden. Recycling brings big change
in the environment, our surrounding
becomes clean and neat.

Recycling is one of the best solutions to solve the fast-rising problems of the world. Do you know that
to make a paper, people cut so many trees just to provide papers around the world? People who are
concerned of the environment specially the trees and forest worries that soon if
cutting of trees would not stop, we will no longer see green in our
environment. To avoid losing to much trees Recycling come up.
Do you know that we can recycle paper at home? Here are simples’ ways to
eliminate household waste at home like use paper printer, junk mails, and kind of
papers to make a unique one. Here are few simple steps to make your own recycled
papers at home.
Materials needed:
1. Wastepaper (never use glossy paper like magazines)
2. Water
3. Blender ( if available)
4. Old picture frame
5. Screen or mesh (secure firmly to the picture frame)
6. Cloth or sponge
7. 13” x 9” pan
8. Wildflower or vegetable seeds for decoration (optional)
Procedures:
1.First, affix the screen or mesh to an old picture frame using nails, staples, or glue to make a
paper mold.
2.Tear paper into small pieces and add to a blender with warm water. Blend the mixture until
the pulp is a smooth consistency.
3. Set the picture frame mold into a 13’’ x 9’’ pan, then pour the pulp into the pan. Make sure
the mold is well-covered, then pull the mold up. Seeds and wildflowers can be added at this
stage – cover the seeds with a little more pulp to embed fully in the paper.
4. Using a towel or sponge, press out the excess water and let the paper dry for a day or two.
The pulp can dry directly on the screen or flip the mold over and let it dry on another surface.
5. Optional: After use, place the paper on a loosened soil surface and cover with a thin layer of
 soil. Sprinkle with water to keep the area damp, and watch your seeds take off.
