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?)

NEW TOPIC BRAINSTORM!

E-WASTE

CAN YOU HEAR ME NOW?

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 e-waste 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• Xerox – • Solid ink – ships in block, no packaging, melts in copier• Copiers designed to be disassembled when outdated.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 DETAILSRCRA

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
