WASHINGTON-How many scrap tires remain piled up around the U.S. awaiting disposal? Probably fewer than 1 billion, based on figures recently compiled by the Scrap Tire Management Council. Earlier estimates had placed the nation's scrap tire pile at as high as 8 billion, with 2.5 billion being the number most widely accepted by industry experts.
However, recent STMC spot surveys in New England and elsewhere have led to a lower estimate, an average of 2.3 scrap tires per person, STMC Chairman John Serumgard said.
The STMC plans to release a report on this subject in 1995.
Idaho adopts plan to block new dumps
BOISE, Idaho-Idaho's Health and Welfare Board hopes to head off the recurrence of scrap tire piles by regulating the operation of waste tire facilities, beginning in January.
The regulations will require the local health district to approve any project involving the stockpiling of old tires for recycling or other uses.
Applicants will have to show the project is not environmentally hazardous, that it is financially viable and that they have the cash necessary to dismantle the facility, if necessary, and restore the land.
The regulations were prompted by two incidents in which tire collection firms in Emmett and Riggins, Idaho, shut down, leaving behind hundreds of thousands of stockpiled tires that now are being cleaned up.
Ohio disappointed with rubber asphalt
COLUMBUS, Ohio-The Ohio Department of Transportation is wondering if adding scrap rubber to asphalt is worth three times the cost, based on preliminary test results.
The state currently is monitoring 10 test sections of highway paved with rubberized asphalt. For the past three years, it appeared the rubberized asphalt sections were outperforming conventional asphalt pavement.
But as of last fall, the test sections appear to have stabilized, performing on par with conventionally paved roads, said Bill Christensen, ODOT's flexible pavement engineer, prompting the state to wonder if it can justify the extra cost.
TDF processor nets 5-year supply pact
FONTANA, Calif.-T.Y.R.E.S. Inc. has signed a five-year contract to supply tire-derived fuel to Riverside Cement Co.
With the Riverside contract and its current supply contract with Mitsubishi Cement Co., both in California, T.Y.R.E.S. said it will be diverting 9 million to 10 million scrap tires from the Southern California waste stream by mid 1995.
The Fontana-based tire processor collects and culls old tires from eight county landfills and three private diversion sites.
