Biodegradable materials can be broken down by microorganisms and absorbed by the environment, while non-biodegradable materials cannot. Biodegradable items include food waste, paper, and grass clippings. Non-biodegradable items include plastic cups, styrofoam plates, and plastic bottles. The document also discusses that biodegradable waste can be disposed of easily and breaks down quickly, whereas non-biodegradable waste is very difficult to dispose of and breaks down slowly. Waste management involves collecting, transporting, and disposing of garbage through reducing, reusing and recycling materials.

1. BIODEGRADABLE AND NON
BIODEGRADABLE

2. BIODEGRADABLE
 What is biodegradable waste?
 Materials or Objects capable of being broken down or decomposed to smaller
products by the action of living things (such as animals or microorganisms).
 After being broken down they are easily absorbed into the soil to become
nutrients or elements.
 Identifying biodegradable waste
 It is generally of plant, animal or mineral origin. It can be easily disposed by the
action of microorganisms or animals. It can be broken down to base elements and
is easily absorbed by the environment without damaging it.

3. Examples of biodegradable items
 Food Waste
 Animal And Human Excrement
 Manure
 Sewage
 Slaughterhouse waste
 Most paper products
 Egg shells
 Grasss
 Flower/brush clippings

4. NON BIODEGRADABLE
 What is non biodegradable waste?
 Materials or Objects not capable of being broken down or decomposed to smaller
products by the action of living things (such as animals or microorganisms).
 Since they cannot be broken down or decomposed they clutter the earth’s surface
and and natural resources and are termed as POLLUTANTS.
 Identifying non biodegradable waste
 It is not of plant or animal origin or is of plant and animal origin but is processed and
modified to change it’s basic natural composition. And hence cannot be broken
down or decomposed to smaller products by the action of living things (such as
animals or microorganisms).

5. Examples of non biodegradable items
 Plastic Cups
 Styrofoams Cups and Plates
 Plastic bottles

7. The difference between biodegradable and
non-biodegradable pollutants
Biodegradable pollutants Non-biodegradable pollutants
Biodegradable pollution is those which are
decomposed by natural biological agents.
Non- biodegradable pollutants that do not
decompose.
They are decomposed and degraded by
microbes.
They are non - decomposed and non-
degraded by microbes.
Biodegradable pollutants can be disposed of
easily.
Non- biodegradable pollutants cannot be
disposed of easily.
Biodegradable pollutants get decomposed
within a very short period.
While non-biodegradable pollutants take a
longer time to decompose.
After degradation, they can be used to
produce biogas, manure, fertilizers, and
compost.
The degradation rate is slow and the
separation and recycling are not easy and
expensive too.
Examples include plants, animals, their waste,
paper, fruits, flowers, vegetables.
Examples include rubber, plastic, chemicals,
and paint plastic.

8. What is waste management?
Waste management is collection, transportation, and
disposal of garbage, sewage and other waste
products. Waste management involves the process of
treating solid wastes and recycling items that don’t
belong to trash. It is about how garbage can be used
as a valuable resource.
Reduce Reuse Recycle plays a very important part in
waste management.

9.  These are some of the things that can be recycled and
reused.
 Cardboard
 Cooking Oil
 Earth and Rubble
 Electrical Appliances
 Small Electrical Appliances and Electronic Products
 Garden Waste
 Glass Bottles & Jars
 Household Batteries
 Lead Acid (Vehicle) Batteries
 Mixed Recycling
 Mobile Phones
 Paper
 Pressurised Containers (gas bottles, fire extinguishers, etc)
 Scrap Metal
