The North Carolina Biomass Roadmap:
Recommendations for Fossil Fuel Displacement through
Biomass Utilization1
The North Carolina Biomass Council developed this Roadmap at the
request of the State Energy Office to be used as a tool to assist
stakeholders in planning North Carolina’s future biomass utilization.
The Roadmap represents the collective assessment and expertise of the
North Carolina Biomass Council and is a result of numerous facilitated
discussions.
For the purposes of this Roadmap, biomass is defined as “any organic
matter that is available on a renewable or recurring basis, including
agricultural crops and trees, wood and wood wastes and residues, plants
(including aquatic plants), grasses, residues, fibers, animal wastes, and
segregated municipal waste…” Biomass can be converted into
biopower, biofuels and bioproducts through chemical and biological
means or can be used to generate heat and/or electricity through direct
combustion, co-firing, gasification, and pyrolysis. Figure 1 outlines the
dynamic nature of biomass utilization.
Energy use in North Carolina
In 2002, North Carolina consumed an estimated 2,633.8 trillion British
Thermal Units (BTUs) of energy, ranking twelfth nationally in energy
consumption. Notice from Figure 2 that petroleum is the largest energy
source consumed at 37%, requiring the state to import 12.1 million
gallons of gasoline and 4.1 million gallons of diesel fuel per day. Also
note that North Carolina already meets 4% of its energy needs using
biomass, ranking eighth nationwide in biomass utilization.2

Figure 2: NC Energy Consumption in 20023
Figure 3 shows that energy consumption in
North Carolina has increased exponentially
and most expect that it will continue to do
so. The Integrated Resource Plan (IRP)
developed by the North Carolina Utilities
Commission predicts that electricity
consumption will increase an average of
1.8% per year over the next 10
years.4The Energy Information Agency
(EIA) predicts that national consumption of
liquid fuels and other petroleum products
will grow around 1% per year.5

Potential Biomass Resources in
North Carolina
North Carolina has an abundance of
untapped biomass resources that are
distributed across the state. Currently, our
national bioenergy policies support the
resources typical of Midwestern states, but
North Carolina has a very different mix of
existing crops and potential biomass
resources.
North Carolina has a significant amount
of lignocellulosic biomass (plant fibers
containing lignin and cellulose) that
could be utilized. Since North Carolina is
unique in its feedstock supply, it requires a
distinct approach to make use of these
resources. Table 1 lists the distribution of
North Carolina’s annual biomass resources
according to their available energy content
for their most likely energy conversion.
Some of these resources are currently being
used in alternate markets, but could be
utilized for energy without significant
impact in North Carolina.
Table 1: Potential Biomass Resources

To put this annual supply of resources into
perspective, Figure 4 illustrates the biomass
supply in relation to North Carolina’s
current energy consumption. As can be seen
from this chart, North Carolina could
meet an additional 10% of its current
energy needs using these biomass
resources.
Combined with the current biomass energy
production, North Carolina could decrease
its current dependence on fossil fuels by a
total of 14%. Furthermore, as new,
dedicated, energy crops such as canola,
hulless barley, industrial sweet potato,
switchgrass, and hybrid poplar are grown,
this percentage could increase.

Bioproducts Development
Some of the world’s largest and most
powerful chemical, energy, and food-processing
companies (such as: DuPont,
BP, Archer Daniels Midland and Cargill)
have begun to form joint ventures focusing
on bioproducts. For example, DuPont has
located a plant in Kinston that produces one
of its newest and most versatile bio-based
polymers, Serona, which is used in the
production of carpeting, clothing, and in
automotive and industrial components.
Smaller North Carolina manufacturers have
also proven adept at making the transition
to bioproducts. For example:
• Hickory Springs Manufacturing
Company in Hickory uses a soy-based
polyol, in place ofpolyurethane, in the
manufacture of its Preserve foam
product.
• Twin City Knitting Company in Conover
incorporates a corn-based fiber, Ingeo, in
producing some of its socks. However,
all of these rely on raw materials derived
from food crops grown outside of North
Carolina.
Targets for Biomass Utilization
and Fossil Fuel Displacement
Biofuels Target: “10 in 10”
 North Carolina should displace 10% of
its gasoline and diesel fuel
consumption by 2017 using in-state
biomass resources while incorporating
energy efficiency measures (i.e.
increased fuel efficiency).
 It is possible for North Carolina to
provide 10% of its current gasoline and
diesel consumption using existing
resources.
4
Biopower Target: “7 by 17”
 North Carolina should displace 7%
of its predicted power consumption
by 2017 using its available biomass
resources while incorporating energy
efficiency measures.
 The December 2006 document,
Analysis of a Renewable Portfolio
Standard for the State of North
Carolina shows this to be practical if
North Carolina uses its existing
resources and reduces its power
demand by 14% through energy
efficiency by 20177.
 This target will most likely be
achieved in conjunction with a 10%
Renewable Portfolio Standard in
North Carolina that includes energy
efficiency for 25% of its RPS.
Bioproducts Target: “Leader in
Bioproducts Research and Development”
 North Carolina should become a
leader in bioproducts research and
development by 2017.
 Universities, community colleges
and businesses have initiated
research and development in
biotechnology which positions North
Carolina as a potential national
leader in bioproducts R&D.
