GARBAGE PATCHGARBAGE 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 UNL AWFUL.

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?)

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 Xerox – Solid ink – ships in block, no packaging, melts in copier Copiers designed to be disassembled when outdated.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

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
