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

applicable in WX because
of mobility and easy
storage.
Does not require level of
investment in equipment
that wall spray does.

CLAY AND MILK PAINT
Clay paint is primarily made of clay, water,


RECYCLED PAINT







Recycled latex paint is made primarily with leftover but unused latex
paint that has been brought to a collection facility by residents and
painting contractors.
This paint is then sent to manufacturers who re-process the paint.
Leftover paint represents a disposal problem
Leftover paint is typically still a usable product
Recycled paint is normally 40-50% cheaper

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 semiconductor 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.
