California Counties Find New Use for Old Tires

CalRecycle Funds Local Projects that Utilize 666,000 Recycled Waste Tires

SACRAMENTO – The California Department of Resources Recycling and Recovery (CalRecycle) recently awarded $410,364 in grants for civil engineering projects in four counties that will use recycled California waste tires in place of conventional construction materials. California generates an estimated 42 million waste tires each year. CalRecycle’s Tire-Derived Aggregate Grant Program promotes the recycling and reuse of California-generated waste tires to keep them out of landfills or illegal dumpsites.

“The use of TDA in civil engineering projects is a win for California’s environment and its economy,” CalRecycle Director Scott Smithline said. “Rather than landfill these tires or create stockpiles that can lead to fires and other public health threats, California is making use of a recycled material that has proven to perform well for these types of projects.”

Tire-derived aggregate is a low-cost, lightweight, and fast-draining product suitable for use in civil engineering applications such as retaining wall backfill, landslide stabilization, and various beneficial uses at landfills (video). The following projects received funding for the third and final TDA grant solicitation of fiscal year 2017-18.

  • Sacramento County: $77,220. Use 3,960 tons of tire-derived aggregate to construct roadways and trenches at the county’s Kiefer Landfill. Project will use approximately 396,000 waste tires. 
  • Santa Barbara County: $158,241. Use 935 tons of tire-derived aggregate for retaining wall repair of  the Ortega Ridge roadway in Summerland. Project will use approximately 93,500 waste tires.
  • Tuolumne County: $120,082. Use 811 tons of tire-derived aggregate for landslide repair project on Italian Bar and Buchanan roads. Project will use approximately 81,100 waste tires. 
  • Riverside County: $54,821. Use 2,735 tons of tire-derived aggregate to construct trenches at 32 sites within the Badlands Landfill in Moreno Valley and Lamb Canyon Landfill in Beaumont. Project will use approximately 95,400 waste tires. 
  • Total: $410,364. Projects will use approximately 666,000waste tires.

The following projects are recommend for awards should additional funds become available.

  • Riverside County: $102,384. Funding to complete landfill projects described above. Project will use another 178,100 waste tires, approximately.
  • Merced Coounty Regional Waste Management Authority. $106,982. Use 1,463 tons of tire-derived aggregate to construct trenches at the  Highway 59 Landfill. Project will use approximately 146,300 waste tires.
  • Total: $209,366. Projects will use approximately 324,400 waste tires.

Eligible projects must be located in California and use at least 500 tons (equivalent of 50,000 passenger tires) of California-generated waste tires. Subscribe to CalRecycle’s TDA Grant Program listservfor notifications about funding availability, applicant and project eligibility, and application due dates.

CalRecycle’s Tire-Derived Aggregate Grant Program is funded through a fee on new tires sold in California
