Air and water are important natural resources
we must use wisely. The P. H. Glatfelter Company has an excellent record of
compliance with environmental laws and regulations. Credit for this successful record goes
to our employees, who are very conscious of the need to use our resources properly, to
minimize pollution, and to handle and dispose of papermaking ingredients and wastes
safely.
Our manufacturing processes are very complex and, while we have a very strong record of
compliance, we do occasionally experience problems. When a problem develops due to
electrical or mechanical failure, or because of human error, we follow the necessary
reporting requirements and take timely action to resolve it. We then determine the cause
of the problem and take additional steps to prevent it from happening again.
Papermaking is a very dynamic process and new technological advances are made each
year. Throughout our history, we have successfully employed many of these evolving
technologies at each of our mills. We are continuing this commitment today, through
modernization and equipment upgrades.
Some of the changes we make are required by new or changing environmental laws. Others
are made by us voluntarily, because we believe they are in the best interest of our
company, the environment and the community.
Air Quality
Just about every activity generates emissions.
When you burn wood in a wood stove or charcoal on the grill, you generate air
emissions. The car you drive creates air emissions. Even you create air emissions, when
you exhale, perspire, and convert food into energy as does every other animal or plant.
Often, the most noticeable emissions coming from a paper mill are those that contain
sulfur compounds. These compounds, which give off an unpleasant odor, result when wood is
cooked and converted into pulp for papermaking. They are so odorous that you can smell
them in extremely low concentrations.
Since the 1970s, the P. H. Glatfelter Company has reduced the transportable odor
emissions from its Spring Grove mill by a minimum 97%. Now such odors are seldom
transported beyond the immediate area of the mill. Locally, we continue to work diligently
to reduce odor within close proximity to the mill.
Other paper mill emissions come from the production of steam, which is used to dry
paper and to generate electricity. Steam is produced in large boilers that burn coal, gas,
wood wastes, and oil as fuel. These fuels release gases similar to those that come out of
a car's exhaust or wood stove -- sulfur dioxide, nitrogen oxide, particulates and carbon
oxides.
Although we usually do not think of these compounds as dangerous to us in the
concentrations in which they are released, we must have special permits from government
agencies to release them into the atmosphere.
Through the installation of new equipment and regular modernization at each of its
locations, the P. H. Glatfelter Company captures about 99% of the particulates and odorous
compounds and more than 50% of the sulfur dioxide and nitrogen oxide generated by
operations corporate-wide. Here are some examples of what we have accomplished:
- A 68% reduction in sulfur dioxide emissions with the installation of a circulating
fluidized bed boiler at the Spring Grove mill. This boiler burns coal to produce steam to
dry our paper and generate electricity.
- A 95% reduction in odor-causing compounds with the installation of a new recovery boiler
at the Spring Grove mill. This boiler, which recycles roughly 98% of the pulping chemicals
used in our process, was installed as part of a $171 million pulpmill modernization
project that was completed in 1994 and included significant environmental upgrades.
Water
Water is a necessary ingredient in papermaking.
At our Neenah, Wisconsin and Pisgah Forest, North Carolina mills, we obtain water from
nearby rivers. At our Spring Grove, Pennsylvania mill, water comes from a creek, which is
augmented by three Company-built reservoirs.
We use water in such applications as:
- "cooking" or treating wood chips and flax straw and recycling wastepaper to
release pulp fibers for papermaking;
- washing pulp fiber throughout the pulping and bleaching process;
- transporting pulp fiber and other ingredients onto a paper machine;
- creating steam needed to dry paper and generate electricity to supply the entire mill
with electric power.
As water passes through our systems, it carries with it excess fiber and other wastes
that are recycled through the papermaking process. The water itself is recycled many times
before we send it to our wastewater treatment facilities.
At wastewater treatment, our manufacturing wastes pass through a sophisticated system
that is designed to remove solid material from water and to treat organic materials
biologically. A byproduct of the wastewater treatment process is a solid, clay-like
material called sludge.
The sludge generated from our pulp and papermaking operation contains primarily
cellulose fiber, calcium carbonate, titanium dioxide, clay and traces of other chemicals.
Today, new technology has been developed which burns the sludge generated from the
production of recycled papers at our Neenah mill and turns it into a useful product. At
our Spring Grove mill sludge is sent to circulating fluidized bed boiler, which is
designed to burn sludge and wood waste as well as coal, for use as fuel in our processes.
