20. Present the results of your activity. Three (3)
minutes may be given per group presentation.
1.How can you make an old pickle jar
useful?
2.What will you do will the pile of old
newspaper in your living room?
3.When the bottle is empty, what will you
do?
Let’s have some clarification.
21. Instead of buying things that we
need, we should try to create
useful things that we need from
waste materials. In this way we
can save money and preserve the
environment.
22. Recycled Item Interesting Facts It Is Recycled Into
Two weeks of daily newspaper
equals one full grown-tree.
Writing paper, newspaper,
cardboard boxes, cereal boxes,
toiletpaper, paper towels
Americans use 2.5 million
plastic bottles every hour. 40
recycled soda bottles make
enough fiberfill to stuff a
sleeping bag
Fiberfill, tote bags, clothing,
containers, carpet, strapping,
fleece wear, luggage, bottles,
pipe, buckets, benches, plastic
lumber, picnic table
You can save enough energy to
operate a television for six
hours by recycling just two
aluminum cans.
Cars, soda cans, aluminum
foil, construction products,
lawn chairs
Glass bottles and jars can be
recycled over and over again.
There is no limit. In the
landfill, glass takes a million
years to break down
Glass bottles, jars, tile road
paving, fiberglass insulation,
marbles
23. Recycled Item Interesting Facts It Is Recycled Into
Some batteries contain heavy
metals such as mercury,
cadmium, and lead which can
pollute our air, ground, and
surface water if thrown out in
the regular garbage.
Recovered cadmium can be
made into new rechargeable
batteries. Nickel and iron can
be recycled into stainless
steel products like pots and
pans
Steel is the most recycled
materials in the U.S. Through
recycling each year, the steel
industry saves enough energy
to power 18 million homes-
1/5th of the homes in the U.S.
Food cans, cars and trucks,
buildings, bridges, tools,
refrigerators and others
appliances, almost anything
made of steel
24. DON’T TRASH US!
Used oil can be recycled and
process to be use again as
new oil or as industrial fuel.
It is illegal to put tires in a
landfill. Tires tend to be
delivered separately so they
can be burned in the Waste-
to-Energy Plant.
Don’t put yard waste in the
trash. Recycle yard waste
into mulch or compost it.
They put nutrients back in
the soil and retain water.
25. 1. Enumerate 3 ways on how large plastic
water containers can be recycled.
a.____________________________________________
b.____________________________________________
c.____________________________________________
2. Cite 2 possible recycling procedures that
can be applied to tin cans.
a.____________________________________________
b.____________________________________________
26. There are some types of waste that should
never be put in the trash can. These waste
maybe dangerous or they may require a
special type of disposal. They should be kept
out of the landfills.
Cite some examples of harmful wastes. List
three (3) possible ways to recycle them.

54. How do you feel after seeing the picture?
Why do you think it happened?
If you were one of the person who was there, what
will you do?
55. 1.Locate a spot in your yard that
receives a lot of direct sunlight to
help keep your compost pit above
110 degrees Fahrenheit. Do not place
the compost pit too close to your
house, as it may emit an unpleasant
smell as it decomposes.
2.Dig a hole in the ground with a
garden shovel that is 2 to 3 feet deep
by 3 feet wide.
Steps on how to make a compost pit
56. 3.Line the hole with masonry lining
or pack in the sides and bottom of the
hole as well as you can, or you risk
the sides crumbling down into your
pit.
Steps on how to make a compost pit
57. 4.Layer the ingredients in the
compost pile. Start with organic
materials, such as kitchen scraps,
shredded newspaper, coffee
grounds, egg shells, grass clippings
or fallen leaves. Then add a layer of
fertilizer, such as horse, cow or
chicken manure. Add a layer of soil
and repeat the layers in order. Stop
when your compost reaches 1 foot
above the compost pit.
Steps on how to make a compost pit
58. 5.Water the compost pit until the
ingredients are soaked. According to
Iowa State University, compost needs
a moisture content between 40 and 60
percent to multiply the beneficial
microbes that are within the pile.
6.Turn the ingredients in the compost
pit once per week with a shovel to
provide proper aeration. Add water at
this time to keep the pile moist.
Steps on how to make a compost pit
59. 7. Use the compost once it becomes
brown and crumbly and has an earthy
smell to it.
Steps on how to make a compost pit
60. What you need:
sack or Sako
trash can
1 big empty bottle of mineral water
1 big pail
pots
5 pcs of Small bamboo
What to do:
1. Form a line to start the activity.
2. Collect waste materials that are
biodegradable found inside the school.
3. Put them inside the trash can, sack or sako.
4. Make an improvised compost pit out of a big
empty bottle of mineral water and pot.
5. Follow steps in making compost
61. Fill in the container with different biodegradable
materials like dry leaves, branches of the tree,
left over foods in the canteen and used papers.
1.Make an airway by placing small bamboo to
easily decay the biodegradable materials.
2. Water the basket composting to keep it moist.
3.Cover it with banana leaf or place it a shaded
area.

63. Recover means taking energy or material from
wastes that cannot be used anymore. Composting
is an example of recovery. The following are some
ways to recover the use materials:
1. Classify the garbage as wet and dry.
2.Place similar items in one container.
64. Recover means taking energy or material from
wastes that cannot be used anymore. Composting
is an example of recovery. The following are some
ways to recover the use materials:
3. Wet garbage includes animal feeds
and organic matter. Animal feeds are
left-over foods, vegetables, fruit peelings,
and others that can be used as feeds for
animals like pigs, chickens, and dogs.
65. Recover means taking energy or material from
wastes that cannot be used anymore. Composting
is an example of recovery. The following are some
ways to recover the use materials:
4.Organic matter actually includes
unused animal feeds, rotting fruit and
vegetables, leaves and grasses, twigs,
and others that rot or decay. These
materials can be composted and used as
organic fertilizers.
66. Recover means taking energy or material from
wastes that cannot be used anymore. Composting
is an example of recovery. The following are some
ways to recover the use materials:
5. Compost organic materials right
away. Build backyard compost pit or
install a home-composter. if
possible, talk with the barangay leaders
about putting up a composter.
67. Recover means taking energy or material from
wastes that cannot be used anymore. Composting
is an example of recovery. The following are some
ways to recover the use materials:
6.If the community produces more
than 25 kilograms of wet garbage,
initiate the installation of a biogas digester
with help from DOST or DILG.
68. Did you know?
Resource recovery is the process in
which a great bulk of solid wastes in
the community such as reusable
metals, papers, plastics, and glass are
brought back to the manufacturing
companies for reusing or recycling. It
usually requires less energy and
causes less pollution.
69. Did you know?
Resource recovery of recyclable
materials occurs in high – technology
resource recovery plants in which
machines shred and automatically
separate the mixed wastes and
change to raw materials for
manufacturers use. The remaining
wastes are burned in incinerators to
produce steam or electricity and the
ash is buried in landfills.
70. Did you know?
Another approach for resource recovery is low –
technology resource recovery. The garbage truck
collects wastes from homes and offices ten
separate the recyclable wastes before throwing
them into the sanitary landfills. The segregated
wastes are sold delivered to scrap dealers, compost
plants and manufacturers. Some communities
have already built Material Recovery Facility
(MRF) in which recyclable wastes bought or
donated from homes are collected and placed in
separate containers or compartments before they
are hauled by trucks to the manufacturers
71. Read and analyze each sentence. Write True if the
concept is correct and False if it is wrong.
___1.Food scraps and fruit peelings are
biodegradable waste.
___2.You recover waste when you refuse to buy a
product that you do not need.
___3.The best way to get rid of trash and save
energy is recovering.
___4.Decomposable wastes can be buried in the soil
and change to compost.
___5.Recovery change the old discarded waste into
a new product
72. From an old newspaper cut an article about
ways on recovering materials. Paste it on
your Science notebook.
