Wood Waste In Tennessee
An Evaluation of Generators and Users
Of
Non-Engineered, Non-Municipal Wood Waste
Solid & Hazardous Waste Conference
Gatlinburg, TN
April 30, 2004
2
We Will Discuss:
• Kinds of Wood Waste (And Why Care?)
• How Much Generated
• How Much Used (Beneficially)
• Economics
• Regulations & Emerging Technologies
• Opportunities To Improve
3
Kinds Of Wood Wasteand
Why We Should Care
• TN Survey Parameters
– Selected SICs
– Non-Municipal
– Non-Engineered
• Impacts
– Economic
– Landfill Space
4
Kinds Of Wood Wasteand
Why We Should CareUnderlying Purpose:
Assist industry in assessing markets to reduce disposal costs and increase profitability. Support EPA’s Resource Conservation Challenge (RCC) & add to TDEC’s initiatives related to this policy’s emphasis on by-product utilization.

• Largest Generators:
– Hardwood Dimension & Flooring Mills
– Sawmills & Planing Mills
– Wood Pallets & Skids
– Special Product Sawmills

Where Wood Waste Is Generated
= Focus Counties With Wood Waste Generators(Counties in Blue/Dashed are largest employers in survey)
Relative Amount of Wood Waste Generated (Representing 75% of All of the Largest Generators):10 3 1 2 8 7 7 9 15 9 4
Relative Geographical Distribution of Wood Waste Generated in TN
8
How Much Wood Waste Is Used Beneficially
• Potential Is 5,000,000 tpy
– Better number is 4,000,000 (excluding TVA)
• Largest Users:
– Boilers & Kilns In TN
– Horse Bedding
– Cattle Bedding
– Boilers In Nearby States
9
Where Wood Waste Can Be Used Beneficially
Counties with one or more wood-burning boilers (permitted boilers)Source data is from Martin Toth, Chief Boiler Inspector
TN Dept. of Labor & Workforce DevelopmentDivision of Boiler & Elevator InspectionData current as of 8/15/03
Counties with one or more wood-burning boilers or kilns with permitted stacks (air permits)Source data is from J. Ron Redus, Environmental Specialist
TDEC - Air Pollution ControlMobil & Air Resources Management ProgramData current as of 8/20/03

Economics
• Kim Raia – CTAS
– GIS & WTRANS
• Load, Transport & Unload
• Tipping Fees (Or Not)
• Payment Or Charge
12
CIS Wood Waste Analysis
• Software Used
• Transportation Model: WTRANS– The University of Tennessee’s Department of Agriculture Economics
developed a computer program called WTRANS, the Wood Transportation and Resource Analysis System. The WTRANS model estimates the cost of transporting wood residues in Tennessee between counties.
– Incorporated into the model are:• Labor costs for loading and unloading
• Hauling costs, including round trip mileage, driver’s wages, truck depreciation, interest and operating expenses
• Truck weight and volume capacity
• GIS Software: ESRI products: Arcview Network Analyst and ArcMap
13
Economics – Mid-Size Generator – Short Distance
• Truss Manfgr.
• Ships 3,400 tpy Wood Chips 2-3 Miles To Boiler At College
• College Pays $15/ton
• Truss Manfgr. Avoids $288,000/yr Compared To Landfill Option
14
Economics – Small Generator – Short Distance
• Pencil Manfgr.
• Gives 95 tpy Basswood Sawdust To Broker
• Broker Hauls To Horse & Poultry Bedding Users
• Pencil Manfgr. Avoids $6,000/yr Compared To Landfill Option
15
Economics – Very Small Generator – Long Distance
• Furniture Manfgr.
• Landfills 35 tpy Scraps & Sawdust
• Furniture Manfgr. Could Avoid $1,074/yr If Ship 89 Miles To Boiler (Where Boiler Owner Pays $13/ton)
16
Economics – Large Generator – Short Distance
• Furniture Manfgr.
• Ships 8,000 tpy Sawdust 10 Miles To Boiler
• Boiler Owner Pays $10/ton
• Furniture Manfgr. Avoids $630,000/yr Compared To Landfill Option
17
Economics – Large Generator – Long Distance
• Tool Handle Manfgr.
• Ships 5,117 tpy Scraps 60 Miles To Boiler
• Boiler Owner Pays $13/ton
• Tool Handle Manfgr. Avoids $390,000/yr Compared To Landfill Option
18
Regulations & Emerging Technologies
• Regulations
– “Clean Wood”
• New Technologies
– BioCycle® Renewable Energy From Organic Recycling Conference1
• http://www.biocycle.net/Conferences/Conference.html
1. Next conference tentatively in Des Moines, IA, Nov. 2004.
19
Opportunities To Improve
• Recycling Markets Directory
• Tennessee Materials Exchange
• Incentives To Recycle
– To more fully support EPA’s Resource Conservation Challenge
20
Summary
• TN industries produce 500,000 to 1,000,000 tons of wood waste annually
• Consumers of this wood waste have the potential to use as much as 5,000,000 tons annually
• Each consumer has a unique set of quality and cost parameters.
• Many generators seem to:
– Not be aware of potential cost-beneficial opportunities, or
– Not pay attention.
