barry commoners laws
BARRY COMMONERS LAWS
  • Everything is Connected to Everything Else. There is one ecosphere for all living organisms and what affects one, affects all.
  • 2. Everything Must Go Somewhere. There is no "waste" in nature and there is no “away” to which things can be thrown.
  • 3. Nature Knows Best. Humankind has fashioned technology to improve upon nature, but such change in a natural system is, says Commoner, “likely to be detrimental to that system.”
  • 4. There Is No Such Thing as a Free Lunch. In nature, both sides of the equation must balance, for every gain there is a cost, and all debts are eventually paid.
laws of thermodynamics
LAWS OF THERMODYNAMICS
  • thermodynamics studies the behavior of energy flow in natural systems
  • The first law of thermodynamics is often called the Law of Conservation of Energy

energy can be transferred from one system to another in many forms. However, it can not be created nor destroyed. Thus, the total amount of energy available in the Universe is constant.

mass or materials balance
MASS OR MATERIALS BALANCE
  • Energy from carbon can be transferred from Geosphere to Ecosphere and Atmosphere but cannot be destroyed
  • Materials Balance is an Accounting of material entering and leaving a system
  • Provides insights for regulating the carbon balance so as not to overload the Atmosphere

  • All materials that enter the economic system will eventually leave it
  • Large amounts of low-entropy energy are needed to drive the economic system
  • All economic activity is essentially dissipative of both energy and materials
overview
Overview
  • Look Beyond methods of waste treatment and disposal.
  • Reduce waste throughout the total material cycle.
    • 1. Make changes within each stage: design and efficiency.
    • 2. Make changes between the stages: loops
    • 3. Make changes beyond the stages: rethinking
  • Opportunity: Help Colorado become world leader in smart design, use and reuse of products and effective use and reuse of natural resources.
slide15
Broad “stages” of industrial activities:
  • Extraction of materials: mining, oil drilling, agriculture, forestry, fishery…
  • Processing of primary materials: cement and metal production, oil refining, food and wood processing…
  • Primary fabricating: tube and wire, plastics, paper construction…
  • Manufacturing: motors, cars, plastic and paper cups…
  • Use of materials and products by public
  • Recycling or disposal of used materials
slide16
“Classes of environmental concerns” regarding the potential impacts of each class of activities:
  • ¨Human health: carcinogenic, respiratory, eye/ear, esthetic…
  • ¨Ecosystems: biodiversity, animals, fish, plants…
  • ¨Materials/energy resources: ore and fossil fuel reserves, forests…
  • ¨Solid residues: municipal or industrial solid wastes
  • ¨Liquid emissions: inorganic and organic contaminants of fresh and ocean waters
  • ¨Gas emissions: inorganic and organic gases and particulate matter emitted to the atmosphere
tracking power plant waste streams
TRACKING POWER PLANT WASTE STREAMS
  • Steam to:
      • Bioplant
          • Yeast to Pig Farmers
          • Fermentation Sludge to Other Farmers
  • Waste Heat:
      • Re-cycled via Municipality of Kalundborg
      • To Fish Farm which sends Sludge to Local Farmers
  • Volatile Ashes: to Oil Refinery
  • Steam: to Paper Factory
  • Gypsum: to Plasterboard Factory
  • Sludge: to Road Construction
tracking refinery waste streams
Tracking Refinery Waste Streams
  • Gas:
    • Plaster Board Plant
    • Electricity Plant
  • Sulfur:
    • Sulfuric Acid Plant
slide24
How much impact can carbon sequestration have on greenhouse gases?

It has been estimated that 20 percent or more of targeted CO2 emission reductions could be met by agriculture soil carbon sequestration.

possible problems
Possible Problems
  • Nonrenewable is not sustainably harvested
  • Potential for high environmental impact if not properly done
  • The process can take a long time

Current Efforts
  • John Deere participates with NREL, DOE, and AFUP to develop a heavy-duty natural gas engine.
  • The engines had increased HP and MPG.

 Rural China uses over 500,000 biogas digesters.

Burning the methane from these digesters yield more energy than directly burning the material.

 300 wells drilled in U.S. landfills provide millions of people with energy.

 1/4 of the electricity and 1/10 of the heating for the BMW plant in Spartanburg, S.C. comes from landfill methane.

FUTURE US EMISSIONS WITH CAP &TRADE (CT)
  • 2007 EIA Analysis of Sen. Bingaman’s suggested amendments of EPAct 2005
  • Projected 44% increase by 2030
  • Projected 21% increase with CT, Energy Efficiency, Renewables & Nuclear
  • Contrast with 6% below 1990 levels required by Kyoto
eesi report on emissions trading
EESI REPORT ON EMISSIONS TRADING
  • Offset Projects for Renewable Energy & Production Methods (to include Extraction, Processing)
  • Efficiency Projects Through Rate base Changes ( to include Generation, Use, Recycling & Waste Disposal)
  • This could be a start for an approach based on Industrial Ecology.
colorado challenge
COLORADO CHALLENGE
