Recycle Your Christmas Tree For Free!

Mt. Diablo Resource Recovery offers 2 options for tree recycling:

Curbside: Please place your bare Christmas tree curbside on your yard waste collection day and we will pick it up for you for no additional charge. If your tree is longer than 3 feet, please cut it in half. Our trucks cannot pick-up trees 3 feet or larger.

Drop-off:  You can take your tree to Contra Costa Waste Service (also known as the Recycling Center & Transfer Station), located at 1300 Loveridge Road, in Pittsburg for no additional charge. Limit one (1) tree per vehicle.

Please remove all ornaments, tinsel, flocking, and tree stand.

Unfortunately flocked trees are not recyclable and must be collected as trash. Please contact our office to schedule a pick-up.
