Save a Tree,
Use Some FeathersBy Sharon Durham March 29, 2002Almost every part of a chicken can be
used, from boneless chicken parts to specially shaped nuggets. Now, previously
ignored chicken feathers may have a new use in todays world.
Agricultural Research Service chemist
Walter Schmidt developed a technique to turn chicken feathers into paper and
strong, less dense plastic composites for products such as car dashboards and
boat exteriors. The Environmental Quality
Laboratory scientist also found feather fiber can replace some of the wood
pulp used to make paper products such as air filters and decorative paper.
Because chicken feather composite paper is made of 51 percent feather fiber and
49 percent wood pulp, only half as many trees are needed. Because of its super fine size and shape, filtration may be the first
commercial venue for processed chicken feathers. Most filters are made from
wood pulp, but feather fiber has an advantage--it is finer than wood pulp. Wood
pulp filters have a width of 10-20 microns, while feather fiber filters
thickness is 5 microns. Thus filters made with feather fiber will have smaller
holes, resulting in more spores, dust and dander being removed from the air and
trapped in the filter. Air filters in homes and office buildings could benefit
from such fine filtration, lessening allergies and sick building syndrome.
Another possible use would be vacuum filters, reducing the amount of spores and
dust that can irritate asthmatic lungs. The technology has been patented and three companies have acquired licensing
rights and are developing marketing strategies. Two pilot plants are in
operation turning feathers into fiber, a process that begins by removing the
light feather material from the hard, central part of the feather, the quill. One of the licensees, Featherfiber Corporation President David Emery, is
marketing the fiber to be used in lightweight, sound-deadening composite
materials for use in office cubicles, cars and sleeping compartments of tractor
trailers. A large scale facility, projected to be complete in two years, is in
the design phase and will be located in southwest Missouri. When complete, the
Missouri plant will produce about five tons of feather fiber per hour, up from
the pilot plant production of 200 pounds per hour. ARS is the chief scientific research agency of the
