Description
CalRecycle’s Tire-Derived Aggregate Grant Program supports engineering uses of shredded waste tires to divert tires from landfill disposal, prevent illegal dumping, and promote markets for recycled-content tire products. Tire-derived aggregate (TDA) is a lightweight, free-draining, less expensive alternative to conventional lightweight aggregates.
The program funds retaining walls, stormwater mitigation, lightweight fill, vibration mitigation beneath rail lines, and landfill aggregate replacement. Projects must use California-generated tires processed in California and incorporate CalRecycle-provided technical assistance and training. Funding supports the TDA portion of projects, including materials, installation, engineering/design, and specified geosynthetic materials.
