Welcome
United States currency plays a significant role in the daily
lives of every American. We earn it, we spend it, we saveit. We accept it at face value as it passes from hand to
hand. And except when the look of our bills change, we
rarely contemplate that there might be more to our
currency than ink on paper.
Just like our fellow citizens, United States currency paper
plays a significant role in the daily lives of my family and
the families of our employees. We earn it, spend it and we
save it. But most important of all, we make it.
We have made paper for currency for more than 230 years. Paul Revere was our first customer
in 1776. Neither he nor Stephen Crane, who made the paper for him, contemplated the
environmental implications of papermaking. To be honest, it would take several generations.
But more than 50 years ago, before Silent Spring, before the EPA and before Earth Day,
members of the Crane family took a look over the horizon and began making some ground-
breaking changes to create a well-managed balance between stewardship of their business and
stewardship of their environment.
We are proud of what we have accomplished over the years, and are happy for the
opportunity to share these accomplishments with you. But we also remain vigilant foropportunities to improve our environmental performance while making the highest-quality ,
most sought-after paper in the world.
Sincerely,
Charles Kittredge
President and Chief Executive Officer

Cranes Raw Materials Tree-FreeSince the American Revolution, Crane has made its currency and banknote
papers exclusively from tree-free raw materials cotton and linen. Backthen, cotton and linen rags were the only viable materials available to
papermakers. It wasnt until the 1870s that trees were cut to make paper .
Crane made a conscious choice then to continue making its papers from
cotton and linen, developing unique expertise with these fibers. The
percentages of cotton and linen have varied over the years, but these two
fibers remain the foundation for U.S. currency paper.
Crane uses several forms of cotton fibers for currency paper . The vast
majority is recovered from the solid-waste stream. We use waste cotton that
is not suitable for textiles, and the trimmings from cotton garment manufac-turers. These fibers are supplemented by staple cotton grown in the
Southwest.
Crane no longer uses linen rags for U.S. currency paper , but rather the flax
fibers that are not suitable for the manufacture of linen textiles.
There are several advantages in using these fibers to make U.S. currency
paper, in addition to the fact that they are tree-free. Cotton and flax are
readily renewable, and Crane has spent generations developing the
infrastructures necessary to recover waste fibers. Because of their inherent
purity, they generate a much higher percentage of papermaking fiber andcreate less waste in the papermaking process than other raw materials.
It also happens that cotton and flax make one of the most durable papers, a
necessary trait for U.S. currency paper. Among the myriad requirements for
strength and durability of currency paper is the double-fold test. Currency
paper must exceed 4,000 double folds. Any normal paper might survive 400.
Crane continues to seek out cleaner
forms of cotton and flax
to reduce the amount of waste
generated and energy used by its raw
material and papermaking processes.

flax fibers are the tree-free
raw materials from which

currency paper.

Processing Cotton and FlaxBefore cotton and flax fibers can be made into paper , they must be refined chemically and
mechanically. Even through cotton and flax are high-yield fibers, there are impurities thatmust be removed before the final papermaking process.
Cotton fibers are protected from rain by a natural oil that needs to be stripped off prior to
further processing. Since the majority are waste fibers, they arrive with small pieces of leaves
and stems. Bales of flax contain portions of the plant stem that have been combed out during
the textile-making process. All of these impurities must be eliminated so they don t end up
contaminating the final product.
To tackle these impurities, Crane literally cooks its cotton and flax fibers
in a large vessel using a solution of so dium hydroxide, commonly known as
lye. Over a period of an hour or two, the oils and other contaminants are
cooked away, leaving a much purer collection of papermaking fibers.
From this point, since the waterproofing oils have been removed, Crane s
raw materials can now interact with water for further refining. First, they are
cut to a shorter length, then run through a series of cleaners to remove any
contaminants not cooked away earlier. To achieve necessary levels of bright-
ness, cotton and flax are whitened using so dium hypochlorite, the same
chemical used in household bleach.
From here, about half of the water in the fiber slurry is pressed out, with theresulting processed raw materials ready to be shipped to the paper mill.

WasteIt was noted in our introduction that 50 years ago Crane began taking steps to reduce its
impact on the environment. The first major initiative was to divert the waste generated bythe papermaking process from the Housatonic River . The industrys first wastewater treatment
facility was primitive by to days standards, but was a very visible statement from a family-
owned business about what could be accomplished outside of a regulatory framework. Crane
undertook this initiative for several reasons:
G Appropriate technology had finally become available
G They saw that sometime down the road, it would be required
G It was the right thing to do now
Today, waste and energy (following page) are closely interwoven.
That papermaking waste from 50 years ago is now being evaluated as a
source of biomass fuel to generate steam for Crane. A year-long pilot programwas begun in late 2010 that, if successful, would provide a portion of the thermalenergy demand to Crane for more than a decade.
Clockwise from upper left:
Cotton and flax fibers not
suitable for papermaking are
processed in Cranes waste-

water is first removed by
suction and gravity; then
by intense mechanical
pressure; the dewateredwaste fibers are composted
with leaf and yard waste to
create topsoil. Clean water
is discharged to the
Housatonic River.

Because Cranes waste materials
are organic in nature, Crane is
investigating their use as a feedstock
for higher-value-added materials.

process are removed from the water discharged to the Housatonic, they become a raw material
Today's wastewater treatment plant is a state-of-the-art chemical, physical
and biological facility designed to treat up to 7 million gallons of water per
day, while removing 99% of suspended and dissolved organic solids.
Once these organic materials left over from the pulp and papermaking
for a new product rather than an environmental liability. After several years of research
and trials, Crane's organic papermaking waste was certified by the state and federalgovernments for land application. At Crane's wastewater facility, water is pressed out of the solids,
then transported to a nearby composting operation where they are mixed with municipal leaf
and yard waste. The end product - topsoil - is used throughout the Northeast as the final
cover for decomissioned landfills.

EnergyPapermaking is an energy-intensive business. Crane uses several sources of
energy in its U.S. currency papermaking operations, including electricity,natural gas and fuel oil.
But Crane has used renewable energy to make currency paper for almost 30
years. In a ground-breaking initiative similar to creation of the first waste-
water treatment facility, in 1979, Crane entered into an agreement with a
fledgling waste-to-energy business called Vicon. An incineration plant was
constructed on land Crane sold to Vicon for $1. The Energy from Waste
plant incinerates municipal refuse to generate steam used for the company
manufacturing operations. From 1981 to 1994, Crane pumped its papermak-
ing waste to a dewatering device located at the V icon Plant for incinera-
tion. Crane agreed to purchase the steam generated by the facility .
Through this partnership, Crane was able to reduce its dependence on oil to
generate steam. Vicon could also use their facility to attract greater volumes
of waste material from around the region, thereby significantly reducing solid
waste in landfills while producing renewable energy.
Today, more than 70 percent of the energy used to making U.S. currency paper
comes from that same waste-to-energy facility. As a result, Crane saves more
than 2 million gallons of oil per year and emits up to 78 percent fewer green-
house gases.

and bio-oil manufacturing facilities.
In 2010, Crane purchased a turbine to once again capture energy from the
Housatonic River to generate electricity for on-site use. The hydro plant, once
operational, will provide a significant portion of the energy needed to process raw
materials for U.S. currency at Cranes Byron Weston Mill. Also in 2010, Crane
completed the engineering design for a back pressure turbine that will take the
flow of the 220 PSI steam from the energy-from-waste plant and generate
around 200 kW of electricity. Th is reduced steam after generating electricity
and at a pressure of 100 PSI will then be used to dry paper on th e US currency
paper machine.

At this writing February 2011 - Crane is addressing the opportunity
to replace fossil fuel-derived energy entirely. To do so, the company
is installing two small turbine projects and is supporting the
development of Berkshire Renewable Power, a project development
company that is working in coordination with ReEnergy of Albany,
N.Y., to build, own and operate a biofuel production faciltiy on
property owned by the company in nearby Pittseld.
In this novel approach, biofuel produced principally from woody,
forest residues, will be converted into a liquid fuel that will bothproduce electricity through diesel-powered generators and replace
fossil fuels used in the manufacturing processes and for heating
buildings.
As a result of supporting this project, Crane & Co. expects to
redirect its energy costs to operations that suport the local economy
through creation of approximatley 100 jobs and an economic
incentive to private landowners that supports sustainable forest
management activities.

Water Cranes First Resource
Alongside quality raw materials, clean water is an essential component
for papermaking. Returning it to the environment as clean as possible isan essential responsibility. Abundant clean water is why Zenas Crane
decided to locate his paper mill here in Dalton. It is among the reasons
we continue to make U.S. currency paper here in Dalton.
Papermaking is a water-intensive process. Fibers must first be cleaned
and refined using water as a suspension medium. To properly form
currency paper on the paper machine, stock must contain about
99 percent water and 1 percent fiber. By the time paper arrives at the
end of the machine, it will contain only 5 percent water .
U.S. currency paper requires up to 1 million gallons of water per day ,
drawn primarily from the underlying Limestone Aquifer via deep wells.
One might think that water is a cheap, even free, resource. But water
needs to be moved from one place to another. It needs to be heated and
it needs to be cooled. It needs to be treated before being discharged.
Every use of water requires energy, so it makes sense to devise ways to
reduce the amount of water used and the energy put into it.
Crane has equipped several papermaking operations with fiber and water
recovery systems that allow water to be captured and reused for appropriate processes. For
instance, a portion of the water used to process raw materials is recovered and used during therefining of fibers. A portion of that water is recovered for other operations. At each step of
the manufacturing process where recovery is possible, the quality of the water is monitored to
determine its next best use.
Water is also an excellent medium to store heat. Where appropriate, Crane is able to capture
heat used in the papermaking process and extract it to heat water for later processing thereby
saving not just water but energy as well.

Stewardship of the EnvironsAs the largest land-holder, largest employer and largest consumer of resources in the area ,
Crane recognizes that not only its manufacturing operations, but also its conduct as acorporate citizen greatly impact the quality of the environment and the quality of life of the
community in which it operates.
As a family business, Crane many times is able to take a longer -term perspective on how it
operates as a business and as a citizen. The company can look beyond its balance sheet and
make decisions based on the quality of life of its community .
In 1993, Crane created The Boulders Conservation Area on 634 of its more
than 1,300 acres of non-manufacturing land. The Boulders lies in three towns
and includes part of the Appalachian Trail corridor as well as the direct
recharge area for the Limestone Aquifer from which Crane draws its water tomake U.S. currency paper. In 2004, the company granted a conservation ease-
ment to the Massachusetts Department of Fish & Game to ensure that the
property would be protected and open to the public in perpetuity .
In 2010, the Old Mill Trail (Dalton Hinsdale Greenway) that Crane and the
Housatonic Valley Association had partnered with, opened to the public. Crane
donated land for the trail for a low-impact walkway that emphasizes the fragile
surrounding natural resources and the history and culture of the river .
In November of 2000, Crane formally decommissioned its Old Berkshire Dam
on the Housatonic. The dam was first built by the company s founder Zenas
Crane in 1801 to provide water for an overshot waterwheel. Crane made its
first banknotes in Dalton in 1806 with power generated by this dam. T wo
hundred years later, Crane became the first Massachusetts company to remove
a dam on their property. By taking down the dam, Crane restored more than a
mile of river to its original free-flowing state.
