2What 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.
3The 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!
4Positive Feedback Loop of Recycling
5Are we promoting feel good purchasing?
6We 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
7Sustainable Dartmouth?
8What if we were responsible for all the waste
that our lifestyle represents?
9The Answer Is SimpleWed Use Less Stuff
10Our 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
11Americans Consistently Use Gains in Efficiency
to Increase Consumption
12A 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

Strategies, John German, American Honda Motor
Co., Inc., May 5, 2006
13More Importantly
14Similar Gains In Efficiency Have Occurred In Home
Construction
- More efficient use of materials
- Higher insulation values
- More efficient heating and cooling systems
15The Result
16How 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.
17What 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.
18Where Are We in Vermont 18 Years Later?

20Trends in Per Capita Generation
21Per Capita Diversion and DisposalVermont and US
22Per Capita Diversion and DisposalCSWD and
Vermont
23Previous 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
24Oregon Per Capita Waste Generation(Including CD
waste, Oregon DEQ)
25Is 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
26Delaware 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
27Vermonts 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
28Commercial Waste By Sector(Range by weight)
29Residential Waste( by weight)
30More 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
31Plastic 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
32Special 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
33But we are not seeing Special Wastes in our Waste
Composition Studies
34Perhaps 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
35Waste 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
36Price 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)
37Charting 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?
38What Do We Target?
- Materials (Producers)
- Generators
- Behavior
39What 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
40What about all Other Wastes?(Washington Dept. of
Ecology)
41Linking waste reduction with carbon reduction
strategies begins to address the entire wasteshed!
42Our 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
43Most Importantly
- Use Less Stuff
- Recognize the best things in life arent things!
- Enough is enough!
