        WHAT ARE BIOBASED PRODUCTS

   According to USDA – “A commercial or industrial
    product (other than food or feed) that is
    composed, in whole or significant part, of
    biological products or renewable domestic
    agricultural (plant,animal, marine) or forestry
    materials.”
   Biobased products are less toxic, less petroleum
    based, and lower in Volatile Organic Compounds
    (VOC).
      VOLATILE ORGANIC COMPOUNDS
 VOCs are organic compounds that have
  high enough vapor pressures under normal
  conditions to significantly vaporize (offgas)
  and enter the atmosphere.
 VOCs are often used in paint, solvents,
  adhesives, carpet, building materials and
  petroleum based derivatives are a common
  source of VOCs.
      BENEFITS OF USING BIOBASED
      PRODUCTS


 Enhance national security by reducing our
  dependence on imported oil.
 Create jobs in the rural and farm economy
 Create healthier and safer workplaces
 Protect and preserve the environment
      BIOBASED/GREEN PRODUCT
      SELECTION PROCESS
 A complex process that involves many
  variables that include an assessment of a
  product’s life cycle environmental impact.
 “Cradle to cradle” – how is a product
  made,how does it perform during its
  lifetime, and what happens when it is
  disposed of.
        SELECTION PROCESS
   Renewability – is the product comprised of
    natural and/or renewable content?
   Recycled content – is product made from
    recycled materials?
   Reusability/recyclability – how is a product
    reused or recycled at the end of its service
    life?
   Durability – is a product low-maintenance
    with a long service life?
      SELECTION PROCESS
 Embodied energy – is the energy required
  to extract, process, package, transport,
  and install a material. Purchasing locally
  produced materials is always preferable.
 Environmental impact – can be considered
  in two ways – indoor and outdoor. Indoor –
  limit offgassing and toxic properties.
  Outdoor – minimize impact on ozone, air
  quality, and toxic waste.
      A REQUIREMENT OR A MINDSET
 In this decade there have been several
  Presidential Executive Orders mandating
  and requiring Federal Agencies and
  Departments to make every effort to
  purchase and use
  biobased/environmentally preferred
  products.
 Many States have followed suit.
      REQUIREMENT OR MINDSET
 But as individuals whether professionally
  or personally there must be a MINDSET- A
  BELIEF that purchasing and utilizing
  biobased/green products and materials has
  value and is important.
 This mindset will serve as the foundation
  and motivation to move in this direction.
SOYBEANS
              In U.S. 12 billion lbs of
               soybean oil produced annually

              Paints
              Insulation
              Plastics
              Fuel
              Every pound of soybean oil
               used to replace petroleum –
               carbon dioxide in the air is
               reduced by 2.77 pounds
CORN
          America’s #1 feed grain
           crop

          Ethanol fuel
          Corn plastic
          Printers ink
          Corn starch used to make

CORN
          Corn plastic when
           disposed of
           decomposes quickly
           with no emission of
           any harmful toxins or
           waste.

LIGHTING - INCANDESCENTS
               An electric current passes
                thru a thin filament
                heating it until it glows
                and produces light.
               Introduced into this
                country in 1875 by
                T.Edison
               Changed modern society
               Now being phased out –
                even banned in some
                countries
LIGHTING – COMPACT
FLUORESCENT BULBS (CFB)
               Electricity excites mercury
                vapor and produces an
                ultraviolet light that causes
                phosphor coating on inside of
                bulb to produce light
               Much more efficient then
                incandescents
               Not heat producing
               Last longer
               Cost more but significant
                savings realized over life cycle
         LIGHTING – CFB’S
   Invented in the 1970’s by Ed Hammer, a GE Engineer as
    a response to the energy crisis.
   Work much like standard fluorescent lamps
   Contain either a magnetic or electronic ballast that
    controls power
   Use about ¼ the energy of incandescents, produce 90%
    less heat, and produce more light per watt.
   A 27 watt cfb provides about 1800 lumens, compared to
    1750 lumens from a 100 watt incandescent
          LIGHTING – CFB’S
   Purchases of 66 million CFB’S over the past year in the
    U.S. - saved 1.96 billion in energy costs
   Prevented air pollution equal to taking 500,000 vehicles
    off the road
   Avoided the burning of 6.9 billion pounds of coal in power
    plants
   Avoided the emissions of 30 billion pounds of carbon
    dioxide into the atmosphere via power plant exhaust.
            LIGHTING – LEDS




   Light emitting diodes (LED) are special diodes that emit light when
    connected in a circuit – similar to a tiny light bulb that fits into an
    electrical circuit. Except they don’t have a filament that can burn out
    and they produce very little heat.
   They are illuminated solely by the movement of electrons in a
    semiconductor
Lighting - LED
                    LEDS last longer then
                     CFBs and are more
                     energy efficient
                    Used primarily in traffic
                     lights, flashlights, exit
                     signs, etc.
                    They are expensive due
                     to the high cost of semi-
                     conductor materials
                    Provide a more directed
                     light then CFBs
         IN CONCLUSION
   If you have the mindset then you have the motivation to
    do the groundwork that is necessary to incorporate
    biobased/green products and materials into your WX
    program.
   Using more environmentally friendly products in your
    program is important but not nearly as significant as
    ensuring that all weatherized homes are made as energy
    efficient as possible.
