Fitesa Case Study January 18, 2012
CONFIDENTIAL – 2 Case Study - Fitesa Who is Fitesa? 11 production sites globally 2 nd largest Nonwoven Manufacturer in the world Locally - Washougal, WA since 1982 Present Employees: 50 Products: non-woven fabric rolls Fabrics composed of PP, PE, PET, PLA, Green PE, Adflex Washougal site originally designed for three energy intensive non-woven fabric lines. Downsized to one retrofitted production line. Most of energy consumption from original lines came from air usage. Energy Program evolved from capital projects to an energy management process.

CONFIDENTIAL – 14 Case Study – Fitesa – Phase 2 HPEM (High Performance Energy Management) Started Program June 17, 2010 5 year long continuous improvement process Regional collaborative effort Fits well with existing culture of continuous improvement
CONFIDENTIAL – 15 Formation of an HPUM Team Form a High Performance Utilities Management Team that has representatives from all functions in the plant. HPUM Core Team Members HPUM SponsorDave RohrbachPlant Manager Energy ChampionJD HiseyContinuous Improvement Manager Key Team MembersDoug Moore Mechanic Chuck BalesElectrician Gary JonesMaintenance Supervisor Ray MangsOperations Manager
CONFIDENTIAL – 16 Fitesa’s Global Mission and Vision Fitesa’s Mission Add value to Customers, Shareholders & Team by providing high quality products with exceptional service. We will do so by proactively reducing our carbon foot print through better processes and product development. Fitesa’s Vision Be the preferred choice for the supply of spunmelt, carded and air-laid nonwoven fabrics to the Global Hygiene market.
CONFIDENTIAL – 17 Develop Plant Policy, Metrics, & Goals Fitesa Washougal’s Utility Usage Policy Fitesa Washougal will continuously look for ways to reduce our usage of utilities so that we continue to support our environmental and cost strategies in a way that is consistent with our global vision. Fitesa Washougal’s Metrics For electrical energy, our metric is kWh/kg of saleable product produced. For water consumption, our metric is gallons of water purchased/kg of saleable product produced. For water outfall, our metric is gallons discharged/kg of saleable product produced. For natural gas, our metric is therms/day. Fitesa Washougal’s Goals For each element of our utility usage, Fitesa Washougal’s goal is a 5% decrease in each metric per year.
CONFIDENTIAL – 18 Create an Opportunity Register Meet with all plant personnel. Educate them on the mission and goals of the HPUM Team. Ask for their ideas to reduce our carbon footprint. As a HPUM team, created initial list of utility saving ideas. List included all ideas. They are then prioritized. –Some go into Project Hopper and become Capital projects for coming years. –Most ideas will be non-capital projects. The highest priority items will be on a Fitesa Action Plan, the rest left on the Opportunity Register.
CONFIDENTIAL – 19 Example of Opportunity Register
CONFIDENTIAL – 20 Create an Energy Map
CONFIDENTIAL – 21 Create Fitesa Action Plans
CONFIDENTIAL – 22 Primary Tool - Conduct Energy Audits Nine Energy Wasters –Unnecessary Running or Idling –Leaks –Pressure & Friction Losses –Sub Optimized Efficiency –Malfunctions –System Imbalance –Misapplication –Scheduling –Sloppy Processes (Not LEAN)

CONFIDENTIAL – 24 CUSUM – kWh/Kg Production
CONFIDENTIAL – 25 Washougal Site HPUM Best Practices Best Practices – turned into plant policy – will help leverage best use of existing technologies. Plant Lighting –Delamp when not necessary Air Compressor Optimization –Added another Receiver Tank –Reduced from 121 psi to 112 psi Natural Gas Controls – Added controls in main building Calibration of Waste Water Outfall (Sewer) Meters Heating Practices –Reduced heat up times for several operations –Shut off several operations when not in use
CONFIDENTIAL – 31 Global HPUM Committee Created Fitesa facilities will strive to reduce the amount of energy we utilize to produce our nonwoven fabrics through efforts of best practice sharing, trending of kpi’s and a continuous drive for improvement.
