Acronyms
What does PIR stand for?
Post-industrial reprocessed/recycled
Family of materials that either originate from a renewable resource, are biodegradable, or are both.
Bioplastics
The circular approach includes reduce, recover, and these other two terms also starting with the letter "r"
Reuse & recycle
What are greenhouse gases?
Gases that trap heat in the atmosphere and warm the planet
What would be an example of mechanically recycled PCR materials?
rPET from water bottles or rPP from shampoo bottles
What does PCR stand for?
Post-consumer reprocessed/recycled
Materials that are made from renewable carbons (typically plant-based) compared to standard petro/fossil fuel-based carbons.
Biobased
This type of material is also referred to as pre-consumer
PIR
Name two greenhouse gases
Carbon dioxide, methane, nitrous oxide, or fluorinated gases
What would be an example of chemically recycled PCR materials?
ELCRIN™ iQ PBT made from chemically recycled PET water bottles
What does CR stand for?
Chemically recycled
Materials are made from renewable carbons (from bio-waste and processes, like tall oil from paper processing) compared to standard petro/fossil fuel-based carbons.
Biocircular
What are the two common recycling methods? What are the differences?
Chemical - material undergoes a chemical change (depolymerization and repolymerization)
Mechanical - material undergoes a simple physical change
What is a carbon neutral goal? A net zero goal?
CN - CO2 emissions are reduced, equal to that of the CO2 emissions given off through activities of the company
NZ - all greenhouse gas emissions are reduced, equal to that of the emissions given off through activities of the company
What would be an example of mechanically recycled PIR materials?
PC made from headlight lens manufacturers
What does GHG stand for?
Greenhouse gas
Combines traditional plastics with biomaterials like wood, flax, hemp, starch, etc.
Biocomposite
What is the common depolymerization process used in chemically recycling materials?
Pyrolysis
Why do our plastic soda bottles have a lower GWP than aluminum cans or glass bottles?
The heat required to make the PET bottles is hundreds of degrees (450-500°F) lower than aluminum (~750°F) and glass (~1000+°F) requires
What is the tradename for the PA 6/10 OR the PA 4/10 what is made from castor bean oil?
PA 6/10 = HiDura™ S from APM
PA 4/10 = EcoPaxx® from ENV
What does GWP stand for?
Global warming potential
Materials that undergo a chemical process in which microorganisms covert the materials into natural substances like water, carbon dioxide, and compost.
Biodegradable
Why does a higher % of pyrolysis oil introduced to make a biobased material not always result in a better GWP?
Over a certain % of oil used will require a purification process which adds a process and energy usage to do (additional GHG emissions)
Abbreviated LCA, what is the name of the studies that are utilized to show the difference in GWP between different material options?
Life Cycle Analysis
What type of material is the LUMID® from LG made from corn?
PA 5/6
