RECYCLING

WHAT IS RECYCLING?
  • Recycling is a process using materials (waste)
    into new products to prevent waste of potentially
    useful materials, reduce the consumption of fresh
    raw materials, reduce energy usage, reduce air
    pollution (from incineration) and water pollution
    (from landfilling) by reducing the need for
    "conventional" waste disposal, and lower
    greenhouse gas emissions as compared to plastic
    production. Recycling is a key component of
    modern waste reduction and is the third component
    of the "Reduce, Reuse, Recycle" waste hierarchy.

SO...
  • A PROCESS THAT HELPS US SAVE ENERGY AND
    NATURAL REOURCES

RECYCLINGIS

  • Nowadays pollution is increasing, but the
    negative impact of the industrialization could be
    reduced if we all adopt some behaviors which are
    the basis of recycling.

5
5 REASONS WHY RECYCLING IS NECESSARY
  • 1. It saves energy!

6
  • 2.By recycling we keep the air and water clean
    and reduce the amount of waste sent to landfills.

7
  • 3. Recycling conserves natural resources as the
    waste are used as resource in different
    production processes.

8
  • 4. Recycling reduces greenhouse gas emissions

9
5. Recycling saves money and helps create new
jobs.

WHAT CAN WE RECYCLE?
  • ?Paper
  • ? Plastic
  • ? Glass
  • ? Aluminum
  • ? Iron
  • ? Batteries
  • ? Electronic devices
  • ? Mobile phones

11
WHAT IS GLASS MADE OF?
  • Glass is an amorphous (non-crystalline) solid
    material. Glasses are typically brittle and
    optically transparent.
  • The most familiar type of glass, used for
    centuries in windows and drinking vessels, is
    soda-lime glass, composed of about 75 silica
    (SiO2) plus sodium oxide (Na2O) from soda ash,
    lime (CaO), and several minor additives.

12
Glass recycle
  • Glass recycling is the process of turning waste
    glass into usable products. Glass waste should be
    separated by chemical composition, and then,
    depending on the end use and local processing
    capabilities, might also have to be separated
    into different colors. The most common types used
    for consumer containers are
  • colorless glass
  • green glass
  • brown/amber glass.

13
SHOULD WE RECYCLE GLASS?
  • WHY
  •    Up to 90 of the new glass can be made of
    reused glass which would save energy and natural
    resources. Glass is infinitely recyclable without
    losing its qualities.

14
BECAUSE...
  • Glass recycling uses less energy than
    manufacturing glass from sand, lime and soda.
  • Every ton of waste glass recycled saves 1.2
    tons of natural resources and thus it helps
    protecting the environment.
  • It reduces the costs regarding the household
    wastes. 8 of the household waste can be reused
    by glass recycling.

15
  • Glass Recycling is Good for the EnvironmentA
    glass bottle that is sent to a landfill can take
    up to a million years to break down. By contrast,
    it takes as little as 30 days for a recycled
    glass bottle to leave your kitchen recycling bin
    and appear on a store shelf as a new glass
    container.
  • Glass Recycling is Simple
  • Its simple, because glass is one of the easiest
    materials to recycle. For one thing, glass is
    accepted by almost all curbside recycling
    programs and municipal recycling centers. About
    all most people have to do to recycle glass
    bottles and jars is to carry their recycling bin
    to the curb, or maybe drop off their empty glass
    containers at a nearby collection point.

16
Glass
Every month, we throw out enough glass bottles
and jars to fill up a giant skyscraper.
Glass can be recycled an infinite number of times.
A modern glass bottle would take 4000 years or
more to decompose and even longer if its in
the landfill.
Recycling one ton of glass saves the equivalent
of 10 gallons of oil.
The energy saved from recycling one glass bottle
will operate a 100-watt light bulb for four hours.
