About the company
Advanced Composting Systems LLC, a small-business manufacturer based in Whitefish, Montana, designs, builds, installs, and maintains specialized composting toilet systems and facilities for federal land management and park agencies as a 100% prime contractor on small-business set-asides and full-and-open purchase orders. The vendor operates as a limited liability partnership and competes across both set-aside and unrestricted procurement channels.
Advanced Composting Systems serves a concentrated, recurring customer base anchored to the Department of the Interior. The National Park Service Intermountain Region dominates the footprint, accounting for 13 awards worth $1.8 million in combined potential value — representing 34% of the vendor's total 38 federal awards and 58% of its combined $3.1 million in potential value across all sources. The top five customers (National Park Service Intermountain Region, GSA Federal Acquisition Service, Bureau of Land Management Oregon-Washington, Forest Service R5-Pacific Southwest Region, and Bureau of Land Management Arizona Region) cover 81% of combined potential value. Recent named work includes a $123,760 competitive small-business purchase order from NPS Intermountain Region for maintenance and repair of the Supai Tunnel composting toilet facility at Grand Canyon National Park (awarded July 30, 2024), a $46,205 total small-business set-aside from NPS for Pipe Creek Compost Facility maintenance in Grand Canyon National Park (awarded August 21, 2025), and a $46,600 small-business purchase order from the Bureau of Land Management Arizona Region for white pocket composting toilet installation at Marble Canyon (awarded August 28, 2026, with completion by December 30, 2026).
Advanced Composting Systems maintains a foothold on the GSA Federal Supply Schedule (GS07F0205U) with five task orders carrying $952 thousand in combined potential value, providing a vehicle for other federal agencies to place orders. The vendor's award history spans three decades, with activity concentrated in 2022 and 2023; recent years show a lighter annual award count (one award each in 2024, 2025, and 2026). Only one award (combined potential value $47 thousand) completes in the next twenty-four months, reducing near-term recompete pressure. The category concentration reflects the vendor's narrow, specialized niche: top NAICS codes are Sewage Treatment Facilities (12 awards), Prefabricated Wood Building Manufacturing (11 awards), and Septic Tank and Related Services (4 awards). The vendor has obligated $3.2 million across its awards — 103% of combined potential value — indicating actual invoiced work has marginally exceeded stated contract ceilings.
