Task • BPA effects • Harmless Alternatives • Manufacturing Techniques
BPA Effects on Human Physiology Kevin Miles
A Look Ahead… • Previous Statements • Enviornmental exposure to BPA • BPA Leeching • The Endocrine system • BPA linked to cancer • Conclusion
~ 25 ng/kg/day 50,000 ng/kg/day Human Exposure: 52-74ng/kg/day http://www.google.com/imgres?imgurl=http://onwardstate.com/wp-content/uploads/2008/12/water_bottle-300x300.jpg&imgrefurl=http://onwardstate.com/2008/12/20/water-water-everywhere-but-a-storage-dilemma/&usg=__qNetutbQEJVjtGWRfq72AO1LwVU=&h=300&w=300&sz=11&hl=en&start=0&tbnid=WsPcp-pgT6AipM:&tbnh=115&tbnw=114&prev=/images%3Fq%3DWater%2BBottle%26um%3D1%26hl%3Den%26sa%3DN%26rlz%3D1G1GGLQ_ENUS367%26biw%3D740%26bih%3D411%26tbs%3Disch:1&um=1&itbs=1&iact=rc&dur=244&ei=xTVPTOe5HZKlnQemi6CQBw&page=1&ndsp=10&ved=1t:429,r:6,s:0
BPA increased the level of hormone receptors produced by a prostate gland cell • Some dosages of BPA were environmentally relevant
An increase in cell receptors fuels growth of the cell • Cells can proliferate out of control, resulting in cancerous tumor cells.
Conclusions • BPA is harmful in lower doses • BPA can leech into food/beverages at relevant levels • BPA exposure increases risk of cancer
Alternative Polymers Gregory Jackett
The Line up • The Candidates • Strength • Toughness • Liquid Stability • UV Stability • Thermal Stability • The Ranking
UV Stability Copolyester?
The Ranking 1st Copolyester 2nd PETE 3rd Polystyrene
Manufacturing Analysis Isaac Norton
Forecast • Polymerization Method • Safety • Quality • Retooling • Ranking
Reaction Heat Runaway
The Ranking 1st Copolyester PETE 2nd 3rd Polystyrene
Conclusions • Hazardous in small concentrations • Carcinogenic developmental changes • Copolyester’s better material properties • PETE’s better safety and quality properties
Our Solution Is… PETE
Just a Reminder… • The Problem • BPA Effects • Possible Alternatives • Manufacturing Comparison • The Solution
