Section 1 wasting resources
Section 1: Wasting Resources

Why should we care about solid waste?

How much waste does the U.S. produce?

What is in the garbage?

The throw away mentality: OUT of SIGHT… OUT OF MIND


Solid waste
Solid Waste

  • Unwanted or discarded material that is not liquid or gas

  • Out of sight Out of Mind

  • No Waste In Nature

    Two Reasons to Be Concerned:

  • Wasted Resources

  • Causes huge amounts of air, water, land pollution and soil erosion


Wasting resources
Wasting Resources

  • Industrial and agricultural waste

  • Municipal solid waste

Fig. 24-2 p. 533

  • US: 11 billion metric tons/year


Affluenza in action
Affluenza In Action

  • U.S. produces 1/3rd of world’s solid waste and buries ½ of it

  • Most waste comes from mining, oil, gas, ag., sewage, industry

  • Think about a simple product like a computer…how much waste produced to create it (Life Cycle)


Municipal solid waste msw
Municipal Solid Waste (MSW)

  • 1.5% of Solid Waste is MSW

  • Between 1960 and 1990 per capita MSW grown 70%...why do you think that is?

  • 38% is paper, 12% yard waste, 11% food waste, 10% platics

  • E-Waste Growing FAST



Msw continued
MSW Continued…

Garbologists findings

  • 50 year old newspapers still readable

  • Pork Chops decades old

    WHY DO THEY NOT DECOMPOSE????.....what do things need to decompose


Msw continued1
MSW Continued…

Enough disposable diapers each year linked together would go to moon and back 7 times

Enough office paper to build a wall 11 feet high between NYC and SF


What are the options for dealing with waste
What are the options for dealing with waste?

  • Waste management (high waste approach)

    Waste is part of economic growth, lets manage negatives

  • Burying, burning, shipping

  • Waste prevention (low waste approach)

    Before product is produced look to minimize life cycle

  • Reduce, reuse, recycle


Six ideas for less waste
Six Ideas For Less Waste

  • Consume less: Do we Really NEED this?

  • Redesign products to use less resources: How can we make this product using less resources throughout their life cycle

  • Redesign to use and make less pollution: Toxic substances etc.


Six ideas for less waste1
Six Ideas For Less Waste

4) Develop products that are easier to repair, reuse, remanufacture, compost or recycle

5) Design products to last longer

6) Eliminate or reduce packaging (nude packaging)



Burning and burying
Burning and Burying

What are advantages and disadvantages of burning solid waste?

What are the advantages and disadvantages of burying solid waste?




Burning waste
Burning Waste

  • Japan and Switzerland over 50%, U.S. about 16%

  • More than 280 project canceled in U.S. due to high costs, concern among citizens, air pollution etc.


Burying wastes
Burying Wastes

  • Open dumps

  • Sanitary landfills

  • Leachate collection

  • Monitoring wells

  • Emit greenhouse gases (CO2 and methane)


Sanitary landfill

Section 2 minimizing waste
Section 2: Minimizing Waste the rest of the world???

How can we reduce, reuse, recycle our waste?


What is reuse
What is REUSE? the rest of the world???

Cleaning and using the material over and over again increasing the lifespan of the product



Not reuse
Not Reuse… the rest of the world???


Reuse benefits
Reuse: Benefits the rest of the world???

  • Extends resource supplies

  • Saves energy and money

  • Reduces pollution

  • Create jobs

  • Reusable products


Reuse costs
Reuse: Costs the rest of the world???

  • Waste (especially e-waste) can contain harmful substances…especially heavy metals

Many eke out living scavenging for waste in large open dumps


Some success
Some Success the rest of the world???

  • 95% of Finland’s soft drink, beer, wine bottles reused

  • Germany about 3/4th are refilled


Other examples of reuse
Other examples of Reuse… the rest of the world???

Shopping bags and tool libraries


Recycling
Recycling the rest of the world???

What is recycling?

What is composting?

How should we recycle solid waste?

How much waste paper is being recycled?

How feasible is recycling plastics?

Why isn’t more reused and recycled?


What is recycling
What is recycling? the rest of the world???

Reprocessing solid waste into new useful products

5 Categories in US Household Recycling

  • Paper Products

  • Glass

  • Aluminum

  • Steel

  • Some plastics


Characteristics of recyclable materials
Characteristics of Recyclable Materials the rest of the world???

  • Easily isolated from other waste

  • Available in large quantities

  • Valuable


Recycling rates
Recycling Rates the rest of the world???

  • Switzerland, Japan 50%

  • U.S. 30% up from 6.4% in 1960

  • 60-80% is achievable


Wastepaper recycling
Wastepaper Recycling the rest of the world???

  • Easy to recycle

  • Removing ink, glue coating and reconverting into pulp

  • 42% of world tree harvest is for paper

  • Currently U.S. recycles 49% of waste paper

  • Making paper has big enviro impact

Waste management

How plastics are made the rest of the world???

  • Recycling plastic is difficult chemically and economically

  • 10% in U.S. recycled

  • Different resins

  • Biodegradable plastics (bioplatics) offer hope


Types of plastic
Types of Plastic the rest of the world???


Economics of recycling
Economics of Recycling the rest of the world???

  • Paper, aluminum, steel are easy to recycle and make easy economic sense

  • CRITICS: 1) plenty of landfill space, 2) Glass and plastic expensive to recycle

  • Employs 1.1 million people


Why we don t recycle more
Why we don’t recycle more the rest of the world???

  • Enviro Costs not included (externalities)

  • Too few government subsidies

  • Tipping fees at landfills cheap

  • Price fluctuations for goods

  • Often don’t PAUT

  • Life cycle costs often not factored in


Waste management

Did You Know? the rest of the world???States with “bottle bills” (consumers receive a refund per returned bottle or can) have reduced their beverage container litter by 69–84% and total litter by 30–64%.


Composting
Composting the rest of the world???

  • Composting organic waste mimics nature

  • Only 5% of yard waste composted in U.S….could easily be raised to 35%

  • Compost used as fertilizer, topsoil and help restore eroded land

RCRA cleaning agents, paints, and pesticides.

1976 Passed By Congress: amended 1984

  • ID Hazardous Waste and set standards

  • Companies that deal with Haz. Waste over 220 lbs. must get permits

  • Cradle to Grave tracking and submit proof to EPA


Cercla
CERCLA cleaning agents, paints, and pesticides.

Commonly called Superfund

  • Passed in 1980 (NJ Congressman leaders)

  • Established tax on on chemicals to

    1) ID abandoned dumps sites

    2) Clean up groundwater

    3) Establish NPL list for cleanups

Waste management

Why do you think NJ has so many? cleaning agents, paints, and pesticides.


Cercla1
CERCLA cleaning agents, paints, and pesticides.

  • Responsible parties must pay

  • If no party can be found clean ups down using $ from tax on oil and chemical companies (tax expired 1995)

  • 1,250 NPL sites…113 in NJ

  • About 72% clean up underway avg. $20 million per site


Cercla2
CERCLA cleaning agents, paints, and pesticides.

  • Some estimates 10,000 sites could cost $1 trillion…pollution prevention cheaper?

  • Toxic Release Inventory www.epa.gov/tri


Polluter pays principle
Polluter Pays Principle cleaning agents, paints, and pesticides.

  • Who should pay for cleanup when responsible parties can not be found?

  • Currently tax payers

  • 1 in 4 Americans live within 4 miles of Superfund NPL site
