Transcript of Plastic and Its Impact on Humanity

PLASTICS
and its impact on humanity
Addiction to Plastic
Innovation of plastic manufacturing:A significant historical event
Polymerization Process
Impacts of Plastics
The Future of Plastics
1862
Alexander Parkes
Parkesine
Properties of rubber but at fraction of cost
BUT commercialization failed
Ziegler-Natta Catalyst
Enables mass production of plastic
Enables ability to produce the ideal polymer
Professor Karl Ziegler (1953 in Germany)
Discovery of catalyst by accident
Giulio Natta (1954 in Italy)
Applied catalyst to polymerize propylene
1963- Nobel Prize for Chemistry
Awarded to both Karl Ziegler & Guilio Natta
Advantages
Disadvantages
PERMANENCE
Depleting resources
Land, Water, and Air Pollution
Costs of Recycling
olutions for specific needs
Dispose of plastic products in a clean, permanent way
Produce and recycle plastics more efficiently and effectively.
Polylactic Acid (PLA)
Plastic substitute made from fermented plant starch.
Carbon-neutral material
Effectively biodegradable, but with limitations
Plastic Mitigation- "Baroplastics"
Massachusetts Institute of Technology (MIT) developed new method for creating and forming plastics.
Shapes plastics at room temperature using high pressure
Can be reshaped with no thermal degradation, increasing recyclability.
Requires lesser energy to produce.
