Construction Projects and Contractors

PSSI is Stanford's exclusive hauler. They rent roll-off boxes and dumpsters for constructions/demolition jobs on the Stanford Campus, as well as a host of other services. See what materials are accepted for construction and demolition material recycling.  

Contractors must pay for the first box in advance, unless a Stanford University work order is submitted. Once credit is established, then invoicing can occur.


PSSI has one to eight cubic yard dumpsters for regular collection service and one time events. These bins are emptied by frontloader trucks come in many styles: counterbalance, loading dock, etc. The bins can be used for recycling, compost, and landfill material and can come with wheels or no wheels. Blue dumpsters are generally used for recycling, green for compost, and black for landfill.

Frontloader Trucks

To get an understanding of the space needed to deliver and service a frontloader dumpster, please take a look at the pictures of the truck. Be careful of overhead hazards, such as tree limbs, and ensure there is clearance on both sides of the truck.

Roll-off/Debris Boxes

PSSI carries four roll-off box sizes: 8, 15, 20, and 30 cubic yard capacity. The 15, 20, and 30 cubic yard boxes also come in short and tall heights. These boxes are serviced by our Roll-off Trucks and need a certain amount of dedicated space to drop-off and pick up. When assessing where to place the box, be aware of overhead hazards, such as tree limbs, and ensure that there is clearance on both sides of the truck.
