Research
Highlights
Since its inception
in 1994, TIP has funded more than 200 research and development projects.
Recent activities in each industry sector are highlighted below.
Textiles/Carpet
New
recycling plant:
Georgia's textiles/carpet
industry transports over 200 million pounds of solid waste to Georgia
landfills each year at a cost of more than $5 million in tipping
fees alone. Honeywell International, in cooperation with DSM, developed
technology that will significantly reduce the amount of carpet going
to Georgia's landfills. The company built an $80 million recycling
plant in Augusta to convert carpet waste into virgin quality nylon
for use in new carpet and automotive parts. The facility, called
Evergreen Nylon Recycling Center, began operations in November 1999.
Evergreen will process 200 million pounds of carpet waste annually
and employ 75 workers. Eighty used-carpet suppliers have already
signed up, and the company expects to have a nationwide supply chain
of 200 within three years. Two Georgia carpet makers and Ford Motor
Company have expressed interest in purchasing Evergreen's recycled
product. Honeywell partnered with TIP to develop a computer logistics
model to minimize Evergreen's cost of collecting used carpet for
its production process.
Wrinkle-free
clothes:
TIP researchers
found a solution for a major economic threat to Georgia's cotton
textile manufacturers and apparel makers. Demand for wrinkle-free
apparel is growing steadily, with the domestic market alone valued
at more than $10 billion. But most wrinkle-free finishes contain
formaldehyde, a chemical banned in many international markets because
of potential health risks. UGA researchers developed a cost-effective
finish that is formaldehyde-free and exhibits better wrinkle resistance
and strength retention than the finish commonly used by textile
and apparel makers. Columbus-based Callaway Chemical Company licensed
the finish and formed a joint venture with Cotton, Inc. and another
Georgia company. They expect the new finish to gain a major share
of the U.S., European, and Japanese markets.
Microorganism
growth in carpets:
Georgia's commercial
carpet makers called on TIP to help solve a problem threatening
their market share. School districts in 31 states have removed carpet
from classrooms because of concerns about mold and mildew growth
and its impact on children's health. TIP lab work identified the
leading microorganisms in mold and mildew growth as well as the
two carpet finishes that best inhibit its growth. In early FY2000,
TIP researchers installed test carpets in two classrooms in Florida.
The test carpets will remain in place until August 2000 while researchers
from UGA analyze the presence of microorganisms. The TIP team is
also looking at different carpet constructions (various weaving
techniques and backing materials) to prevent microorganism growth.
Reducing
toxicity in carpet wastewater:
Carpet companies
in Dalton called on TIP to help reduce COD, or chemical oxygen demand
loads, in their wastewater. More than 50 carpet mills are served
by Dalton Utilities whose treatment system will soon reach or surpass
its design limits if industry cannot reduce its wastewater volume.
TIP researchers found that the major cause of COD is the finish,
or lubricant, applied to yarn during the carpet-making process.
Last year, they worked with Shaw Industries and Solutia to develop
a new process that reduces total lubricant usage by 40 percent,
lowering both wastewater toxicity and chemical costs. Shaw Industries
is constructing and testing a pilot-scale system with plans to implement
a full-scale system in 2000. Georgia's carpet industry can save
$3 million per year by implementing this technology.
Reducing
chemicals in denim manufacturing:
Georgia is
home to five denim manufacturers employing over 6,000 workers. The
process of making denim requires large amounts of indigo and sulfur
dyes - a typical denim plant spends $13 million per year on chemicals,
not including the cost of treating chemical-laden wastewater. UGA
and Georgia's denim makers worked on reducing the amount of dyes
and chemicals used in the manufacturing process. In less than a
year, one mill reduced its chemical costs by more than $100,000
and another mill save $80,000.
Reducing
textile wastewater:
At Springs
Industries in Griffin, TIP researchers helped the company modify
its towel-manufacturing processes and reduce wastewater by half
to 900,000 gallons from 1.8 million gallons per day. At the company's
yarn-dyeing plant, researchers suggested changes that reduced that
facility's wastewater by 25 percent. Because these technologies
can be applied to other textile operations, managers from dozens
of textile companies across Georgia visited Griffin to see Springs'
system and learn firsthand how it might work in their mills.
Internet
Recyclers:
To help Georgia's
carpet and textile companies find appropriate waste handlers, TIP
developed an Internet site - http://www.fcs.uga.edu/tmi/wastedb/
- which lists more than 200 waste dealers and material recyclers,
and gets more than 500 "hits" every month. More than 150 textile/carpet
companies around the state have used the site to solve waste disposal
problems.
