GARBAGE PATCH/GARBAGE GYRES
• Floats between Hawaii and
California
• Twice as big as Texas
• Can be 30 m deep
THE TROUBLE WITH PLASTICS IN THE OCEANS
• don’t biodegrade like other debris
• break down over time into smaller and smaller pieces while still
maintaining their chemical make-up
• As the pieces get smaller fish, mammals, birds and even
plankton will consume the pieces which are not digestible
• While the plastics may not be visible to the eye, studies have
shown that in some areas the concentration of plastics
outnumbers the concentration of plankton by a ratio of 7:1
PLASTICS MOVE DOWN STORM DRAIN. LITTER IS
UNLAWFUL.
CONSIDER THE THREE STEPS OF RECYCLING: WHY IS THIS
MATERIAL NOT BEING RECYCLED?
• Right answer: It’s too hard to
collect and the stuff is too mixed
up.
• (What’s vague? What needs
clarification? What details can
you add to show off mastery?)
CONSIDER THE THREE STEPS OF RECYCLING: WHY IS
THIS MATERIAL NOT BEING RECYCLED?
• Polymers
• Collection
• Reprocessing
• Repurchasing
• Melting point
• Markets
• Postconsumer
wastes
• Downcycling
NEW TOPIC BRAINSTORM!
CAN YOU HEAR ME NOW?
E-WASTE
EWASTE SPECIFICS
Most common: TV’s
• Monitor: Pb
• Circuit board: Hg, Pb, flame
retardants
• Cables and wires: Cd, flame
retardants, PVC
Smart phones
• Circuit board: Cu, Au, Pb, Ag,
Pd
• Battery - Li
TOXIC COMPONENTS IN A PC
•
Secret life of a cell phone
• National Geographic - High Tech Trash January 2008
PAIRS • Apply the concept of product of service to the ewaste dilemma
• What would manufacturers have to do to make this
Product of Service idea a reality?
THINK IT’S A PIPE DREAM?
• Xerox –
• Solid ink – ships in block, no packaging, melts in copier
• Copiers designed to be disassembled when outdated.
Components are refurbished and included in newer
models where possible.
• Toner cartridges – returned to be refilled, not thrown
out.
XEROX
• “Before is was categorized as green, we thought of
it as just being efficient.” –Ursula Burns, Xerox
President
• “I’m in a funny business – I’m looking for ways that
companies can print less. Printing is not going to go
away, but we think you have to print more
efficiently . . .We know that if we do that we can
continue to grow.” – John Kelly, president of global
services at Xerox
MODULAR PHONES
RIGHT V. AP: EXPLAIN WHY EWASTE SHOULD NOT BE
DISPOSED OF IN A LANDFILL.
• Right: E-wastes like smart
phones have toxic chemicals in
them. In the landfill, the toxins
can leak into the liquid. The
liquid could get into
groundwater and hurt people.
• (What’s vague? What needs clarification? What
details can you add to show off mastery?)
AP DETAILS!
• Cadmium, Lead, Mercury
• Leachate
• Wells/drinking water
• Working landfills are open
• Mechanical compaction
• Brain damage, birth
defects, cancer
• Plastic Liners
• clay
NEW TOPIC: BRAINSTORM!
TWO NEW LAWS! RCRA AND CERCLA
RIGHT V AP: COMPARE AND CONTRAST RCRA AND
CERCLA
• Right: RCRA is about
preventing hazardous waste
problems. It identifies what’s
hazardous and how to handle
it. CERCLA is designed to clean
up hazardous waste problems.
It’s called Superfund.
• (What’s vague? What needs clarification? What
details can you add to show off mastery?)
AP DETAILS
RCRA
 Sanitary landfills
 Defined hazardous waste: toxic,
flammable, reactive, corrosive
 Required cradle to grave
management of hazmat
 95% of materials are still
“linguistically detoxified” – high
level nuclear waste, household
hazardous wastes, mining and
fracking wastes
CERCLA
• Identifies and prioritizes hazmat sites
• Toxicity, exposure, size
• National Priorities List
• Seeks responsible parties for payment
• Companies
• Taxpayers
• Remediates sites
• Mechanical , Phytoremediation,
bioremediation
