PSSI Employees

Peninsula Sanitary Service, inc (PSSI) and the Stanford Recycling Center is a locally owned and family owned business that provides waste collection, processing and hauling services to Stanford University.  The University partners with PSSI to reduce waste, increase landfill diversion, and move closer to zero waste (defined as at least 90% diversion).

PSSI offers waste sorting education and training to all groups on campus and regularly partners with staff and student groups to conduct waste audits. These events offer the campus community an experiential learning opportunity while providing valuable data to PSSI about the content of campus landfill bins. These audits help Stanford to focus its programs for the most significant results.

In addition, PSSI hires student interns to help the campus reduce waste by playing an active role in the Campus Zero Waste Program.  Getting to Zero Waste requires a combination of education and infrastructure.  Zero Waste Interns have opportunities to create new ways to communicate our waste reduction message to different community groups, research best practices, collect and analyze data, and implement new programs.

We offer frontloader garbage and cardboard dumpster service, roll-off bins, recycling, composting and trash bin and cart service, residential collection, and street sweeping to Stanford University campus.  In addition, we do bulky item pick up and operate the Stanford Recycling Drop Off Center.  PSSI is dedicated to the highest quality customer service delivered with pride and professionalism. Our staff is ready to help you with your waste issues!
