Charting Vermonts Course to Waste
PreventionTrends in Waste Generation and
Composition

2
What is Waste Prevention?
  • Waste represents a stream of distinct products
    and materials we use everyday as individual and
    institutional consumers
  • One common definition of Waste Prevention is
    the design, manufacture, purchase or use of
    materials that reduces the amount and toxicity of
    waste generated.

3
The Problem With this Definition
  • Assumes that we, as a society, will continue to
    consume the materials and products at the same
    rate
  • That is one of the reasons that we feel good
    about recycling!

4
Positive Feedback Loop of Recycling
5
Are we promoting feel good purchasing?
6
We All Know The Numbers
  • According to the US EPA, the average person
    generates about 4.5 pounds of municipal solid
    waste every day
  • And the average continues to grow despite
    significant light weighting of many products and
    packages
  • And that is just municipal solid waste from
    consumption looking forward

8
What if we were responsible for all the waste
that our lifestyle represents?
9
The Answer Is SimpleWed Use Less Stuff
10
Our Economy Has Depended on Growth in Consumption
  • We measure GDP all about growth
  • Economic growth translates to waste growth
  • All indicators are that we consume more, not less

11
Americans Consistently Use Gains in Efficiency
to Increase Consumption
12
A Few Examples
  • Honda Motor Company has increased fuel
    efficiency 1.5 per year since 1987, but all of
    this has been used to increase other attributes
    more highly valued by consumers
  • Performance (speed)
  • Comfort (air conditioning, size, electronics)
  • Utility (size)
  • Safety
  • Source Climate Change Near Term Actions and
    Strategies, John German, American Honda Motor
    Co., Inc., May 5, 2006

13
More Importantly
14
Similar Gains In Efficiency Have Occurred In Home
Construction
  • More efficient use of materials
  • Higher insulation values
  • More efficient heating and cooling systems

15
The Result
16
How Do We Compare?
  • American homes are on average double the size of
    those in other richest nations
  • Homes in 2002 required 890 ft2 per person of
    materials as opposed to 290 ft2 in 1950
  • Study found 1500 sq ft home with relatively poor
    insulation characteristics still outperformed the
    3000 ft2 home with good insulation
    characteristics.
  • Sources House Size Matters, Michael Horowitz,
    VBSR.
  • Small is Beautiful U.S. House Size, Resource
    Use, and the Environment, Alex Wilson and Jessica
    Boehland.

17
What about Waste Generation?
  • Vermonts 1989 Solid Waste Management Plan
    states
  • We assume that during the next 13 years efforts
    by the State and regions resulting from Act 78,
    together with increasing disposal costs, will
    stop increases in per capita generation rates.

18
Where Are We in Vermont 18 Years Later?

MSW Disposed Vermont vs. US(Thousands of tons
per year)

Trends in Per Capita Generation
21
Per Capita Diversion and DisposalVermont and US
22
Per Capita Diversion and DisposalCSWD and
Vermont
23
Previous Graphs Ignore CD Waste
  • Add another 1 lb per capita per day to Vermonts
    waste
  • Add another 1.5 lbs per capita per day to CSWD
    waste
  • CD waste often includes bulky waste masking
    actual growth in residential and commercial waste
  • EPA estimated 2.75 lb per cap in 1996

24
Oregon Per Capita Waste Generation(Including CD
waste, Oregon DEQ)
25
Is the Green State of Vermont Worse than the US
Average?
  • Maybe, but we are skeptical of US EPA (Franklin)
    data, especially when used at the State level
  • Our recent data from the State of Delaware shows
    large discrepancies, especially in critical
    materials

26
Delaware Comparison
  • 35 less corrugated recycled than reported by
    Franklin
  • 10 times more non-bottle plastic than reported by
    Franklin
  • 4 times more pallets recycled than reported by
    Franklin
  • Franklins estimates for asphalt and concrete
    generation only 35 of what we found

27
Vermonts Waste Composition
  • DSM conducted Vermonts only Waste Composition
    Study for DEC in 2001
  • Sorted Residential and Commercial Waste
  • Urban/suburban and rural generators
  • Commercial waste by sector

28
Commercial Waste By Sector(Range by weight)
29
Residential Waste( by weight)
30
More Importantly, What Are The Trends in Waste
Composition?
  • Package light-weighting continues
  • First thin walled cans, bottles and containers
  • Flexible package replaces rigid one (milk sacks,
    boxed wine)
  • Substitution of plastic and aseptic for glass
  • Substitution of boxboard for steel cans
  • Light-weighting of durables
  • Less ferrous metal per appliance
  • Substitution of plastics and composites for metal
    and wood in electronics
  • Change in location of waste generation
  • More food prepared at restaurants, less organic
    waste at home

31
Plastic Volume Is Increasing
  • EPA reports plastic was 16.4 of discards by
    weight in 2005 (0.5 in 1960 and 5 in 1980)
  • Recent study in Israel found plastics made up
    largest volume (nearly half at 46) of material
    by into landfills with paper at 15 and
    corrugated at 13
  • Recent work in South Africa shows significant
    differences in the compaction ratios for plastic
    waste in landfills compared to other materials

32
Special Wastes Increasing
  • Electronics
  • New gadgets
  • Obsolete electronics
  • Computer and cell phone growth
  • Compact fluorescents (and mercury)
  • Bulky wastes with shorter product life
  • Desire for new furniture and appliances
  • Lower costs and longevity of appliances

33
But we are not seeing Special Wastes in our Waste
Composition Studies
34
Perhaps Most Importantly
  • Proliferation in niche products
  • An entire isle in the supermarket devoted to
    paper towels and toilet paper
  • An entire isle devoted to bottled water
  • An entire isle devoted to snack food
  • The result huge increases in supermarket square
    footage and attendant carbon footprint
  • Heating, cooling, lighting

35
Waste and Carbon Emissions
  • Same struggle we face with reducing carbon output
  • Kyoto cars increased from 1.3 to 2 million from
    1990 - 2002
  • Result growth in carbon 8 since 1990
  • American citizen averages 21 tons CE per year vs.
    4.5 average globally
  • 4.5 tons for car, 6.2 for hh electricity use
  • US totals 6 billion tons of 25 billion globally

36
Price Signals
  • Value of Recyclables
  • We believe that material prices will continue to
    trend upward resulting in more recycling
  • Disposal tip fees rising, but not enough to
    encourage waste reduction
  • Disposal costs represent only about 30 of a PAYT
    bag rate of 1.50 - 2.50
  • Collection/transport a large part of cost (and
    main contribution to CE in waste industry)

37
Charting the CourseWhat should we be measuring?
  • Volume vs. weight?
  • Per capita disposal may not be increasing by
    weight but by volume
  • Landfill costs based on volume available
    volume charges send different price signal
  • Recovery rates instead of recycling rates?

38
What Do We Target?
  • Materials (Producers)
  • Generators
  • Behavior

39
What Is Baseline Generation?
  • Include materials recycling?
  • What should we count in disposal
  • With or without CD
  • Bulky waste accurately accounted
  • Exclude practices such as
  • Backyard composting
  • Grass clippings left on lawn

40
What about all Other Wastes?(Washington Dept. of
Ecology)
41
Linking waste reduction with carbon reduction
strategies begins to address the entire wasteshed!
42
Our Suggestions for Waste Prevention Tracking
  • Consider volume
  • Include CD waste
  • Disaggregate bulky waste and count it
  • Dont rely on US EPA data
  • Collect capture/recovery rate data
  • Send strong economic signals
  • i.e. PAYT

43
Most Importantly
  • Use Less Stuff
  • Recognize the best things in life arent things!
  • Enough is enough!
