In this presentation importance of plastic recycle was discussed and the situation of Spain was showed. Plastic recycle process was analyzed.

2. INTRODUCTION
PLASTIC: A wide range of synthetic or semi synthetic organic
solid materials suitable for the manufacture of industrial
products. Plastics are polymers of high molecular weight. They
may contain other substances to improve performance and/or
reduce costs.
PROPERTIES OF PLASTIC:

3. TYPES OF
PLASTICS
THERMOPLASTICS: Plastics that do not
undergo chemical change in their composition
when heated. It can be molded again and
again.
Examples:
THERMOSET PLASTICS: Plastics that are
permanently "set" once, they're initially formed
and can't be melted.
Examples:

8. Effects of
Plastic on
Human
Health
The extraction of resources for plastics often involves
fracking or other invasive processes, and many release a
significant amount of harmful substances into the
atmosphere or pollute the surrounding environment. At
the other end of the plastic cycle, waste management
technologies such as incineration, gasification, and
pyrolysis also release toxic metals such as lead, mercury
and acid gases into the surrounding air, soils, and waters.
In its physical form, most of the plastics which are harmful
to us are almost invisible to the naked eye. Micro and
nano-plastics are being found in a significant proportion of
test sites, such as in sea salt, rainwater, and even
mountaintops - as the plastics evaporate and fall as
precipitation with the water molecules.

9. WHY
RECYCLE?
In landfill, both synthetic and naturally occurring polymers
don’t get the necessary exposure to UV and microbes to
degrade.
• Landfills not destroy plastics , it preserve the poison
forever.
• The toxic chemicals escape from the landfills and
contaminates the water sources.
• When there are too many plastic in landfills, they are
often destroyed in incineration factories.• Causes Lung
Cancer
• Contaminates Soil
• Contributes to
Green House effect
Consequently it:

RECYCLING
Plastic recycling is the process of recovering
scrap or waste plastic and reprocessing the
material into useful products, sometimes
completely different in form from their original
state.
• Recycling is a viable alternative in getting
back some of the energy stored in the
polymers.
• As petroleum prices increase it is becoming
financially viable to recycle polymers rather
than produce them from raw materials.

11. RECYCLING
PROCESS
The simplest of plastic recycling processes involves collecting, sorting,
shredding, washing, melting, and pelletizing. The actual particular
processes vary based on plastic resin or type of plastic product.
Most plastic recycling facilities use the following two-step process:
Step One: Sorting plastics automatically or with a manual sort to make
sure all the contaminants are removed from the plastic waste stream.
Step Two: Melting down plastics directly into a new shape or shredding
into flakes then melting down before being finally processed into
granulates.
