Plastics are polymers, large molecules made of repeating units Plastics are polymers, large molecules made of repeating units of smaller molecules (of smaller molecules (monomersmonomers) that are chemically bound ) that are chemically bound together. A polymer is like a chain in which each link is a together. A polymer is like a chain in which each link is a monomer. monomer.

Resistance to chemicals, water and impact.

Good safety and hygiene properties for food packaging.

Excellent thermal and electrical insulation properties.

Relatively inexpensive to produce.

Lighter weight than competing materials, reducing fuel consumption during transportation.

Plastic is one of the few new chemical materials which pose environmental problem.

Plastic in the environment is regarded to be more an aesthetic nuisance than a hazard, since the material is biologically quite inert.

Plastic is cheap, it gets discarded easily, and, its persistence in the environment can do great harm.

Once a plastic products are used, most plastic go into landfill, or garbage. Each year more and more plastics are ending up littering the environment.

Many plastics, particularly PVC, when burned result in emissions of the deadly poisons named dioxin.

Dioxins are highly persistent compounds, with the potential to become increasingly concentrated in living tissues as they move up the food chain. It is often considered to be the man-made compound most toxic to animals.

Plastic debris is proliferating in the environment, especially in the marine environment, and is causing numerous problems for humans and wildlife.

The majority of marine debris is plastic.

Beaches around the world are littered with plastic debris. Even the most remote islands, uninhabited by human beings, are becoming inundated with non-biodegradable plastics.

“Plastics, like diamonds….

ARE FOREVER”

Only 3.5% of plastics are recycled in any way.

63 pounds of plastic packaging goes into landfills in the U.S. per person per year.

Broken, degraded plastic pieces outweigh surface zooplankton in the Central North Pacific by 6 to 1.
