NAICS 325315 – Compost Manufacturing covers the industrial-scale production of compost from organic waste streams, including food residuals, yard trimmings, biosolids, and other biodegradable materials. This sector supports sustainable waste management and soil health initiatives by converting organic waste into nutrient-rich, pathogen-free soil amendments used in land reclamation, erosion control, and green infrastructure projects. In government contracting, compost manufacturing plays a critical role in federal and state environmental restoration programs, municipal solid waste diversion efforts, and USDA-funded conservation initiatives. Facilities in this NAICS typically employ controlled aerobic digestion, temperature monitoring, and quality assurance protocols to meet EPA and state regulatory standards for Class A or Class B compost. The industry bridges environmental compliance, circular economy goals, and land management practices within public sector sustainability agendas. No contractor data is available for this NAICS code, indicating limited visibility of prime contractors or subcontractors in current federal award records. This may reflect the sector’s reliance on local or regional vendors, small businesses, or public works departments rather than large federal primes. No agency data is available, suggesting that procurement activity is either decentralized, conducted at the state or municipal level, or bundled under broader environmental services contracts rather than tracked as a distinct line item. The competitive landscape is characterized by niche operators with specialized permitting, odor control, and pathogen reduction capabilities. Opportunities exist for contractors with expertise in organic waste processing, regulatory compliance, and public-private partnerships focused on municipal waste-to-resource programs. Demand is growing as agencies prioritize landfill diversion and climate-resilient soil management, though procurement remains fragmented across local governments and environmental programs.

Small Business Size Standard

The SBA threshold that decides who can bid NAICS 325315 work as a small business.

550 employees
Applies to the whole industry code

The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.

13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Competition

How many companies historically bid on federal awards in NAICS 325315, from bidder counts reported on USAspending.

Too few awards in NAICS 325315 report bidder counts (10 of 11) to summarize competition. The broader industry family below gives the closest honest picture.

How this code compares up the NAICS hierarchy. Parent cohorts pool every code under their prefix, so they are the steadier baseline when a 6-digit sample is thin.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
