Tire Recycling, Cleanup, and Enforcement Grants

Tire-Derived Aggregate (TDA) Grant Program

The California Department of Resources Recycling and Recovery (CalRecycle), administers tire grant programs to provide opportunities to divert waste tires from landfill disposal, prevent illegal tire dumping, and promote markets for recycled-content tire products. The Tire-Derived Aggregate (TDA) Grant Program provides assistance to civil engineers in solving a variety of engineering challenges. TDA, which is produced from shredded tires, is lightweight, free-draining, and a less expensive alternative to conventional lightweight aggregates. Eligible applicants include cities, counties, special districts, state agencies (including offices, departments, bureaus, and boards), qualifying Indian Tribes, and private for-profit entities that fund public works projects located in California.
