Mountain Trails Baskets
Staining Operation for Wood Basket Production
Objective
To establish a new finishing operation, increase overall productivity
and introduce options for using environmentally-friendly coatings.

Background
Mountain Trails Baskets (Mt. Trails), established in 1988, manufactures
fine quality heirloom wood baskets in Templeton, Pa. and employs
less than 10 people. Its clients include some well-known manufacturers
such as L.L. Bean, Williams-Sonoma and Ducks Unlimited. As a result
of the rapid expansion of the wholesale business, the company expects
a 200% increase in orders during the next two years.
To meet production operations and establish a new manufacturing
facility, significant changes were needed in the plant layout, process
design, material supply, equipment use and employee retention. The
finishing operation used at Mt. Trails presented a bottleneck in
the manufacturing process and did not allow the company to efficiently
serve and supply its customers.
Mt. Trails previously made baskets by using the best-standing timber,
soaking maple wood in hot water, and using hardwood to create a
double-woven basket-shell. This process begins once the basket-shell
is formed and is completely dried and pulled tight for durability.
Once the rimmed basket is dried, the basket is finished with wood
strips for reinforcement, handles and needed accoutrements.
For added variety and differentiation between the products, Mt.
Trails stains some of the baskets. This process involves dipping
the baskets into organic solvent stains followed by two days of
drying prior to packaging.
Mt. Trails evaluated options to improve its finishing operation,
increase overall manufacturing productivity and determine the feasibility
of environmentally-friendly coatings. By seeking assistance from
ETAC and the Pennsylvania Technical Assistance Program (PENNTAP),
Mt. Trails now reaps the benefits of faster turnaround time and
delivery to customers, improving both marketability and its competitive
edge.

How ETAC Helped
When Mt. Trails approached ETAC and explained its basket-making
process, ETAC assessed the finishing and drying operations and investigated
ways to improve them. Following assessment, ETAC conducted experimentation
in the laboratory to define coating and drying alternatives. Investigating
these alternatives established the feasibility of waterborne stains,
an improved application method and the value of using dehumidified
air for improved drying.
Upon completing the evaluation, ETAC provided suggestions to Mt.
Trails on how to streamline the finishing operation by using a high-efficiency
manufacturing design for the waterborne stains and an improved drying
cycle. By using waterborne stains, Mt.Trails greatly reduced the
emission of volatile organic compounds (VOCs) from the plant. In
addition, the high-efficiency drying dramatically decreased the
drying time by using filtered, dehumidified air with a relative
humidity at least 30% below ambient air. This allows the water to
be quickly removed from the stained basket shell without the use
of additional heat. Once the moisture of the wood reaches 6%, the
basket is packaged and shipped.

Results/Benefits
By altering the process to include environmentally-friendly coatings
and rapid drying, Mt. Trails benefited from reduced environmental
impact, improved working conditions and increased production. This
effective work-cell process enables Mt. Trails to manufacture more
consistent products at a lower operating cost with significant reduction
in VOC emissions and improvements in air quality. In summary, the
benefits accrued include:
- Reduced VOCs and hazardous waste by converting to environmentally-friendly
waterborne stains in the finishing operation and improving the
drying cycle.
- Improved working conditions by eliminating the solvent-borne
organic stains at the manufacturing facility that tend to emit
undesirable odors.
- Reduced likelihood of both fire and health hazards by reducing
the solvent use in the facility.
- Improved and increased production by employing rapid drying
technology to achieve fast moisture removal.
- Reduced operating costs by a minimum of 10% to 15% due to improved
manufacturing and drying processes as well as a reduction in the
solvent waste.
