Casella Waste Systems, Inc. (CWST) Business Profile

What it does

Casella Waste Systems is a regional waste services company headquartered in Rutland, Vermont. Founded in 1975, it collects, transfers, recycles and disposes of waste for households, businesses, municipalities and other organizations. Edmond “Ned” R. Coletta is its president and chief executive officer.

The company’s operations cover much of the path waste takes after a customer throws it away. Collection trucks pick up material from homes and businesses; transfer stations consolidate it for transport; and landfills receive waste for disposal. Some facilities in that chain are owned or operated by third parties. Casella also processes recyclables and organic materials, including biosolids, and sells products recovered from processing.

Casella organizes its solid waste operations into Eastern, Western and Mid-Atlantic regions. Its Resource Solutions business serves larger customers with needs that can extend beyond a single location, including recycling, organics and waste-management services. The company also provides brokerage services, arranging services for customers with broad resource-management needs.

As of January 31, 2026, Casella owned or operated 86 solid waste collection operations, 72 transfer stations, 32 recycling and processing facilities, eight Subtitle D landfills, two landfill gas-to-energy facilities and one landfill permitted to accept construction and demolition materials.

How it makes money

Casella earns most of its solid waste revenue from fees for collection and disposal, including landfill, transfer station and transportation services. Commercial and industrial collection services are generally performed under agreements, while municipal services often use municipal contracts. Most residential collection is sold by subscription to property owners or occupants, although some residential services are provided under contracts.

A majority of commercial and industrial collection agreements run for one-to-five years. Prices reflect factors such as how often waste is collected, the containers and equipment supplied, the type and amount of material, the distance to a facility and disposal or processing costs. Landfill and transfer-station customers generally pay a tipping fee per ton of waste delivered.

The Eastern, Western and Mid-Atlantic segments manage collection, transfer and disposal in their respective regions. Within each region, Casella organizes operations around local “wastesheds,” where collection and facility divisions work together. The company seeks to send more of the waste it collects to its own facilities, a practice it calls internalization.

Resource Solutions earns revenue from processing and tipping fees, sales of recovered commodities, and National Accounts brokerage and resource-management services. At certain landfills, Casella also sells electricity, energy credits and capacity, and renewable natural gas rights, generation, sales and related tax credits. Processing fees and an adjustment fee that moves inversely to recycling commodity prices are intended to reduce exposure to swings in those prices.

Revenue for the second quarter of 2026 was $543.7 million. Solid waste pricing was up 5.5% overall in the quarter, while solid waste volume was down 0.6%.

Customers and how it sells

Casella serves residential, commercial, municipal, institutional and industrial customers. It sells residential collection both directly to individuals and through arrangements with municipalities, property owners and other third parties. Commercial and industrial customers commonly use service agreements, and municipalities can contract for collection and disposal.

The Resource Solutions segment serves larger commercial, municipal, institutional and industrial customers with varied waste and recycling needs. It also provides processing to municipalities, commercial haulers and waste generators near its processing facilities. National Accounts provides brokerage and resource-management services to large organizations, as well as collection, disposal and recycling services to customers with multiple sites.

Casella has operating locations in Vermont, New Hampshire, New York, Massachusetts, Connecticut, Maine, Pennsylvania, Delaware, New Jersey, Maryland and West Virginia. The Eastern, Western and Mid-Atlantic regions manage geographically defined solid waste operations; Resource Solutions operates across the company’s footprint rather than within one region.

Demand varies by season. Revenue has historically been higher in late spring, summer and early fall, partly because construction and demolition waste volumes decline during the northeastern winter. Casella has also introduced a customer payment portal, phone app and updated website.

Suppliers and costs

Casella’s operating costs include purchased materials and payments to third parties for transportation and disposal, including tipping fees. Other major costs include employee wages and benefits, fuel, vehicle and equipment maintenance, insurance, facility costs and landfill expenses. Landfill expenses include leachate treatment and obligations for final capping, closure and post-closure care.

The company uses both its own trucks and third-party contractors for long-haul transport. Fuel surcharges in third-party contracts apply above specified fuel-price levels. Casella also charges customers fuel-recovery fees that float with fuel prices, although contractual restrictions and competition can limit its ability to pass those fees through in every case.

In the second quarter of 2026, Casella’s floating fees offset the dollar increase in fuel costs, while the additional fuel costs and recovery fees created roughly 40 basis points of margin headwind. The company consumed approximately 15 million gallons of diesel fuel in its solid waste operations in fiscal year 2025.

Casella also invests in trucks, facilities and technology. Its operating costs rose in fiscal year 2025 partly because of acquisitions, higher third-party disposal rates and higher wage and benefit rates.

Competitive position

Casella competes on service quality, breadth and price. In larger, more densely populated markets, it competes with national solid waste companies including Waste Management, Republic Services and Waste Connections. It also faces regional and local companies, municipal and district operations, alternative disposal facilities such as incinerators, and rail-served transfer stations that send waste outside its footprint.

Casella says national competitors may achieve greater economies of scale. Public facilities can have advantages from user fees, charges or tax revenues. Competitors can cut prices to win customers or bid for contracts, and waste companies also compete for acquisition candidates.

Our reading: Casella’s integrated collection routes, transfer stations and landfills are a meaningful local advantage because they let it connect several stages of service and direct collected waste to its own facilities. That advantage varies by market: some facilities in a wasteshed belong to third parties, and other operators can offer competing disposal routes.

Our reading: Landfill capacity is another source of protection where local disposal options are scarce, but its strength depends on Casella retaining and expanding permits. Northeast capacity has tightened, while permits can restrict volumes or fail to be renewed. Service agreements and residential subscriptions support repeat business, although contracts can be lost through competitive bidding.

Growth opportunities

Casella pursues growth through acquisitions, new contracts and development projects, alongside price increases and operating improvements. It seeks acquisitions that add routes and facilities within existing markets or extend its reach into new ones. It also aims to direct more collected waste to its own facilities and expand available landfill capacity.

The company acquired nine businesses in fiscal year 2025. In January 2026 it acquired Mountain State Waste, adding collection operations in West Virginia and a transfer station operation in southwestern Pennsylvania. Casella completed five acquisitions so far in 2026, representing approximately $165 million of annualized revenues. These transactions include an acquisition in Pennsylvania on July 1.

Casella is also working on landfill development and expansion. It expects a permit to expand airspace at its Hakes construction and demolition landfill and is pursuing expansion efforts at other sites. At McKean in Pennsylvania, a new transfer station came online and Casella began moving intercompany waste there by rail from Massachusetts in July.

Operational initiatives include route consolidation, truck automation and systems integration. Casella completed the migration of Mid-Atlantic customers to its new revenue, billing and operations system and payment portal in early May. It expects Mid-Atlantic operating cost reductions of $5 million in 2026 and another $10 million over the next two years. Resource Solutions also provides a way to expand services to larger customers with recycling and resource-management needs.

Structural risks

• Permits and landfill capacity: Casella may be unable to obtain or renew permits or expand its landfills. It expects the NCES landfill to stop accepting waste by the end of 2027, and plans to cease operations at the Ontario County landfill at the end of fiscal year 2028.
• Environmental obligations: Regulation and potential liabilities can require spending on compliance, remediation, closure and post-closure care. Increased regulation of PFAS and other emerging contaminants could add costs or litigation risks.
• Acquisitions and integration: Casella may be unable to acquire businesses on acceptable terms or realize expected savings after a purchase. Integration consumes management resources, and acquired properties may carry unknown environmental liabilities.
• Costs and labor: Fuel, labor and third-party service costs can rise, while competition for drivers, mechanics and other workers can increase recruiting and retention costs. Contractual restrictions and competition can limit fuel-cost recovery.
• Competition and customer contracts: Competitors can lower prices, and municipal contracts are typically subject to periodic bidding. Casella may lose business or need to reduce prices to retain it.
• Commodity prices and regional exposure: Lower prices or demand for recyclable materials can affect revenue and cash flow. Casella’s concentration in the Northeast and Mid-Atlantic also exposes it to regional downturns, regulation and severe weather.

Bottom line

Our reading

Casella combines recurring collection services with transfer, disposal and recycling infrastructure in regional markets. Its ability to route waste through its own facilities and add local acquisitions supports that model, while constrained landfill capacity can make existing sites valuable. The same model depends on permits, operating execution and integration: landfill closures, environmental obligations, rising costs and competition can limit the benefits of growth.
