Keystone Composting Solutions, LLC

Keystone Composting Solutions, LLC, a Pennsylvania-based partnership or limited liability partnership, supplies carbon material mulch and compost feedstock to the federal government as a prime contractor on full-and-open purchase orders with no set-aside designation.

The vendor operates exclusively as a prime and has worked with a single federal customer: the U.S. Department of Agriculture's Animal and Plant Health Inspection Service Veterinary Services division. All three awards in the source data are purchase orders placed by USDA Veterinary Services between February and March 2026, each carrying short performance windows measured in days to weeks. The work centers on delivery of carbon material (mulch) for composting operations at USDA facilities in Lancaster County, Pennsylvania, in support of highly pathogenic avian influenza (HPAI) response efforts. The three named awards are a $20.7 thousand purchase order placed February 5, 2026, for carbon material for windrow building at Lancaster 51 (completion February 10, 2026); a $29.25 thousand order placed February 27, 2026, for 1,500 yards of carbon material mulch at Lancaster 65 (completion March 3, 2026, performed in Lititz, Pennsylvania); and a $117 thousand order placed March 17, 2026, for 6,000 yards of carbon material mulch at Lancaster 71 (completion April 24, 2026, performed in Columbia, Pennsylvania). Combined potential value across all three awards is $167 thousand, and combined dollars obligated equals the full potential value.

The vendor's recent activity is entirely concentrated in USDA Veterinary Services — 100% of awards by count and dollar value. No parent contract vehicles, IDVs, GWACs, or BPAs appear in the source data; all work is direct purchase order activity. The vendor carries no subcontract footprint in the source record.
