Environmental & Waste Services (7.2) · Industry Index

Overview

Environmental & Waste Services covers the collection, disposal, recycling, remediation, treatment, and consulting that manage waste and protect the environment. Sized from its native segments — solid waste, recycling, and environmental consulting — it represents roughly $119 billion, with hazardous-waste and remediation services profiled (and sized) under adjacent industrial sectors.

Demand is recurring, regulation-driven, and recession-resistant (waste is generated regardless of the economy), and the sector is consolidated in solid waste around a powerful oligopoly (Waste Management, Republic Services, GFL, Waste Connections) alongside fragmented specialty environmental services. Growth is propelled by regulation (PFAS and emerging contaminants), recycling and the circular economy, ESG, and infrastructure — making it one of the most active private-equity and strategic roll-up arenas.

Companies: ~32,186 firms

Firms by employee count

84.1% of firms have fewer than 20 employees: 27,059 micro-businesses, below most mandates.

The investable universe5,127 firms with 20+ employees

20–99: 3,85275%
100–499: 78715%
500+: 48810%

Percentages are of the 20+ employee universe. 20–99 and 100–499 are the lower-middle market; 500+ is at scale.

Waste is the most predictable cash flow in this sector and the most consolidated: route density is the entire economic argument, and the operator with the most stops per mile wins any market it is in. That is why the segment trades at infrastructure multiples despite being a collection-truck business.
