About NIGP 33572
NIGP 33572 Soil Conditioners: Compost, Marine Humus, Sulfur, Synthetic Polymers, Mulch, Etc. is an Item code under which state and local governments procure landscaping and environmental remediation materials—chiefly mulch (hardwood and engineered wood fiber), compost, erosion control seed mixes, and related soil amendment supplies for grounds maintenance, landfill operations, and stormwater infrastructure. Recent solicitations show municipalities, counties, and special districts buying mulch for routine landscape maintenance, engineered mulch media for odor control at utility facilities, compost and seed mixes for erosion control and site stabilization, and aggregates paired with erosion control geosynthetics for landscaping projects. Issuing bodies span city procurement offices (Savannah, Tucson), county departments (Sacramento County, Sarasota County, Hillsborough County, Boulder County), school districts (Parkway School District, Missouri), and specialized authorities such as district waste and stormwater management divisions. Sacramento County's Department of Waste Management and Recycling and Hillsborough County's Water Resources Department appear as repeat buyers managing large composting and landfill operations.
Geographic activity concentrates in California, Florida, Georgia, South Carolina, Missouri, Colorado, and Arizona based on recent postings. Representative opportunities include Sacramento County's RFB 2026-RFB-0049 for erosion control services (hydroseeding and compost application at multiple landfill and transfer stations, bids due June 11, 2026); Sarasota County's IFB 262888RM for odor control mulch bed media refurbishment and replacement at nine vacuum stations over five years (bids due August 7, 2026); Parkway School District's IFB 2740 for hardwood mulch and engineered wood fiber on a blanket purchase-order basis with estimated annual spend of $50,000 (bids due September 17, 2026); the City of Savannah's pre-bid for landfill cover material (bids due August 4, 2026); Boulder County Parks and Open Space Department's SOQ for landscaping products and erosion control materials including mulch, aggregate, and geosynthetics on a tiered short-list arrangement (proposals due May 27, 2026); and Greenville County's RFP 26099 for mulching services at the Administration Building (proposals due April 21, 2026, with one-year term and four renewal options).
