This document discusses garbage and its components. It explains that garbage is separated into useful and non-useful components at landfills. Useful garbage, or biodegradable waste, can be reused through processes like composting and vermicomposting. Non-useful, or non-biodegradable, garbage cannot be reused and is buried at landfills. The document emphasizes the importance of reducing, recycling, and reusing materials to limit garbage production and promote environmental sustainability.

2. Introduction

3. How do we deal with Garbage

4. Components of Garbage
Garbage at the landfill is
separated as
Useful Component
Part of the garbage that can be
re-used is called as Useful
component. It is then treated by
different processes to make it
non-toxic
Non-useful Component
Part of the garbage that cannot
be re-used is called as Non-
useful component. It is then
separated and spread over the
landfill and covered with a layer
of soil

5. Useful Garbage includes

6. Types of Garbage
There are two types of Garbage
Biodegradable (Useful)
Type of waste, typically
originating from plant or
animals, which can be
decomposed by other living
organisms/ method.
Non-Biodegradable (Non-
useful)
Type of waste that cannot be
decomposed by any method

10. Red-Worms and their role in
Vermicomposting

11. Recycling
We can recycle waste paper and re-use it for many purposes.
Paper suitable for recycling is called as “Scrap paper”

12. Plastic: Boon or Curse !! (CLICK)
Some kind of plastics an be recycled, not all of them
Problems arise when we use plastics excessively and are ignorant
about ways of disposing them
All kinds of plastics release toxic gases upon heating or burning
These gases may cause many health problems, including cancer,
in humans
Plastic bags cannot be recycled
Stray animals swallow these plastic bags and fall sick

13. Save Environment: Reduce, Recycle
& Re-use (3 R’s)
 Reduce
 Reduce unnecessary usage of natural resources
 Recycle
 Recycle and use the natural resources in different
forms
 Waste segregation is vital for recycling
 Re-use
 Use the same resource/s again and again (to the
extent possible)
