This sections provides a collection of case studies of
textile facilities that have actually implemented techniques and technologies to
improve efficiency and reduce waste. (2000) Brittany
Dyeing and Printing Corporation reduces energy consumption and air emissions
through use of foam finishing technology. (1997) Spectrum
Dyed Yarns had maximized its water and wastewater capacity as well as its
boiler capacity, but needed more capacity to meet increasing production needs,
by increasing water use efficiency the company was able to meet increasing
production demands while reducing water consumption per pound of product
produced. Water usage per pound of yarn dyed, and cost savings calculations are
included. (1997) Renfro
reduces the sulfur dioxide (SO2) emissions from its boilers with low-sulfur fuel
and reduces chlorine bleach usage from its processes. Price savings of chlorine
use reduction are included. (1996) Nisshinbo
California, Inc. (NCI) working with ADI Control Techniques Drives (ADI-CT)
of Hayward, California retrofitted 15 of the system's fan motors with variable
frequency drives (VFDs). This change enabled the fan control dampers to be fixed
in a fully open position, and improved the system's air flow control and energy
efficiency. (1996) DuPont's
Cape Fear polyester yarn plant implemented several waste reduction efforts which
resulted in significant savings. By changing simple procedures such as sampling,
spinning position, and yarn package changes, the facility was able to reduce
product waste. Additionally, process modifications eliminated the use of
methanol and decreased VOC emissions by lowering process temperatures; waste PET
plastic is recycled rather than landfilled; and unused process equipment was
turned into a glycol recycling center for DuPont. Waste reduced, annual cost
savings, and additional activities are included. (1996) Hubert
Textiles Pty. Ltd. operates a textile dyeing and printing business.
Significant cost savings and environmental benefits have resulted from the
installation of a computerized paste mixing system. A payback of approximately
2.5 years was achieved through reduced raw material and waste costs and
efficiency improvements. (1996) Springs
Industries reduced their solid waste generation through reusable chemical
storage containers, recycling, reusable shipping pallets, a switch to a
non-hazardous parts washing solvent, waste stream segregation and sizing reuse,
and process waste reduction through teams and goal setting. Includes annual
waste reduction and savings calculations. (1995) Guilford
Mills determined that the majority of VOCs were emitted during heat setting
and printing. VOC emissions were reduced by an average of 67% in 6 plants. Most
reductions were accomplished by switching from a solvent based edge gum to a
water based adhesive. (1995) Bloomsburg
Mills has actively pursued waste reduction and recycling throughout its
production processes, including chemical substitution of their dye carrier with
less hazardous chemicals, reusable bulk chemical storage containers, a recycling
program, and process heat and water reuse. Calculations of air emissions, and
solid waste reduction and associated cost savings are included. (1995) Hoescht
Celanese, which produces polyester fibers, has implemented a corporate-wide
program to reduce waste and emissions. Projects include the elimination of
trichloroethane used for degreasing, implementation of a leak detection and
repair program and a recycling program, and process modification to remove toxic
compounds from wastewater, distill them, and use them for boiler fuel. Waste
reduction and annual savings calculations are included. (1995) West
Point Stevens successfully implement p2 activities including air emissions
reduction; boiler fuel change; energy, water, and chemical use optimization; use
of bulk chemical storage containers; recycling; and replacing cardboard spinning
tubes with reusable and recyclable PVC cones. Additionally, Westpoint Stevens
initiated a chemical approval committee to find alternative, less toxic
chemicals for use. Calculations of annual waste reductions and savings are
included (1995) Cleveland
Mills implemented a waste reduction program, resulting in significant
reductions in wastewater releases, air emissions, and solid and hazardous waste
streams. Calculations of formaldehyde, solid waste, and wastewater pollutant
reductions are included. (1995) An
integrated textile manufacturer (weaving, dyeing, and finishing) made
several changes in its textile manufacturing process to reduce the use of
trisodium phosphate, sodium hydroxide, and sodium nitrate. TSP, previously used
in scouring, was completely replaced by sodium carbonate. These reductions cut
the company's use of toxic chemicals by more than 20,000 pounds per year, saved
it $5,000 in chemical purchases and regulatory fees, and enhanced worker
health.. (1995) Sara
Lee Knit Products Corporation's process modifications to reduce salt, dye,
and water usage through process optimization, segregate wastes to allow
wastewater reuse, and improve wastewater quality through filtration. Includes
annual waste reduction and savings calculations. (1994) Milliken
implemented an extensive environmental program that eliminated use of extremely
hazardous chemicals at the facility, reduced the use of hazardous chemicals,
reduced solid waste, and reduced energy consumption. (1994) Skjern
Tricotage-Farveri uses an enzyme to replace a chemical agent (such as
thiosulfate) in bleach neutralization leading to reduction in water and energy
consumption. (1992) An
Australian facility uses environmental management to improves product
quality in wool scouring. (1992) An
Australian yarn manufacturing plant uses cleaner production and waste
minimization techniques. (1992) An
Australian facility uses cold pad batch dyeing of cellulosic fabrics with
fiber reactive dyes to reduce waste and chemical use. (1992) Cranston
Print Works uses cleaner production measures in printing and finishing. (1992) A
Norwegian company producing plastic coated textiles reduces solvent use.
