SCRAP TIRE MARKET DEVELOPMENT BY TERRY GRAY TAG RESOURCE RECOVERY TIRE WORKSHOP 2013 SAN ANTONIO, TEXAS APRIL 3, 2013
PERSPECTIVE • FIRST PROGRAM IN MINNESOTA IN 1984 • MANY U.S. STATES STILL DON’T HAVE SUCCESSFUL PROGRAMS • <1% UTILIZED IN 1984, BUT ABOUT 80% IN 2011 • MEXICO CAN ACCELERATE ITS GROWTH BASED ON GOOD AND BAD HISTORICAL EXPERIENCES
ENERGY • CEMENT KILNS • POWER GENERATION • PAPER MILLS • DEDICATED FACILITIES • PYROLYSIS/GASIFICATION
CEMENT KILNS • ENVIRONMENTALLY EXCELLENT • ECONOMICALLY ATTRACTIVE • QUICKLY DEVELOPED • GENERALLY WHOLE TIRES, SOME TDF • NEEDS CONSISTENT SOURCE • PROGRAM CORNERSTONE
POWER AND PAPER INDUSTRIES • SPECIFIC BOILER TYPES INCLUDE CYCLONE, STOKER-FIRED, CFB • DISPLACES COAL OR OTHER SOLID FUEL • USES NOMINAL 1” OR 2” TDF, BEAD WIRE REMOVED
COMPARATIVE TDF PRODUCTION ECONOMICS (CHIP SIZE VS TIRES/YR)
PYROLYSIS • HISTORICALLY UNSUCCESSFUL • NO COMMERCIALLY SUCCESSFUL SYSTEMS IN NORTH AMERICA • OVER $500 MILLION EXPENDED • MAJOR COMPANIES AND SMALL PROMOTERS
CRITICAL ISSUES • TECHNICAL PERFORMANCE • UNRELIABLE OPERATION • EXPLOSIONS/FIRES • ENVIRONMENTAL ISSUES • AIR • CHAR DISPOSAL • ECONOMIC PERFORMANCE • GAS UTILIZATION • OIL ONLY BLENDSTOCK • CHAR MARKET
CIVIL ENGINEERING • LIGHTWEIGHT FILL • DRAINAGE AGGREGATE • WHOLE TIRES IN RETAINING WALL CONSTRUCTION
Dixon Landing Interchange • PROBLEM: Embankment Constructed on Bay Mud • SOLUTION: Use TDA for the core of the embankment • CHEAPEST SOLUTION: Caltrans saved $470,000 • USED: 600,000 tires
Rt. 91 Wall in Riverside, CA • Freeway widening • Objective: show that reduced earth pressures can reduce overall wall construction costs • Length: 260 ft • Tires used: 75,000 PTE
Potential Future Savings for Walls • Lower pressure on wall less rebar • Potential reduction = 28 tons/100 ft • Potential cost savings = $13,000/100 ft
RETAINING WALLS • WHOLE TIRES MECHANICALLY JOINED TO STABILIZE OR RETAIN SLOPE • NOT BROADLY APPLIED IN US DUE TO LABOR COSTS • MINIMAL CAPITAL EXPENSE FOR SMALL VOLUMES
CRUMB RUBBERAPPLICATIONS • SPORTS SURFACES • MOLDED PRODUCTS • RUBBER-MODIFIED ASPHALT • DECORATIVE MULCH
CRUMB RUBBER CHARACTERISTICS • SLOW OVERALL MARKET GROWTH • HIGH CAPITAL • HIGH MAINTENANCE • MARKET CHALLENGES
RURAL CONSIDERATIONS • VOLUME SENSITIVITY • REGIONAL PLANS, COLLECTION CENTERS OR PROCESSING FACILITIES • MOBILE PROCESSING • CAREFULLY EVALUATE BALE APPLICATIONS BEFORE STARTING
SUGGESTIONS • FOCUS ON ENERGY (ESPECIALLY CEMENT KILNS) INITIALLY • DEVELOP CE DESIGN EXPERIENCES AND PRACTICES • BEGIN TO ENCOURAGE CRUMB MARKETS, BUT AVOID PREMATURE OVER-COMMITMENT
PROCESSING EQUIPMENT • APPLICATIONS RANGE FROM WHOLE TIRES TO FINE POWDER • SPECIFIC EQUIPMENT REQUIRED TO PRODUCE EACH SIZE PRODUCT • KNOW MARKET BEFORE PURCHASING EQUIPMENT
KEYS TO SUCCESS • LEARN FROM OTHERS’ SUCCESS AND FAILURE • EVALUATE BEFORE CHARGING • CHALLENGE “MAGIC” PROPOSALS • RECOGNIZE LOCAL MARKET VARIATIONS • RECOGNIZE REALITY
