LANSING (AP) -- General Motors Co. is reaching a landmark when it comes to keeping stuff out of landfills.

The Detroit-based automaker is expected to announce Tuesday that its 100th facility has achieved "landfill-free" status.

A distribution center in Lansing helped GM reach the milestone. The company says it first reduces waste and then focuses on recycling and reuse.

That includes recycling scrap cardboard into sound absorbers for vehicle roofs and used tires into air deflectors on pickup trucks.

The automaker says it recycled or reused 2.6 million metric tons at its plants worldwide last year - equivalent to about 38 million garbage bags. GM says it's reduced total waste by about 43 percent since 1997.
