1. Meaning of Waste Collection Market Concentration

Waste collection market concentration describes a situation where a relatively small number of companies control a substantial proportion of the collection of municipal, commercial, industrial, recyclable, or other waste.

Competition law becomes relevant because waste collection is often local in nature. Transportation costs, access to depots and disposal facilities, municipal licensing, specialized vehicles, environmental regulation, and long-term public contracts can make it difficult for new competitors to enter a particular area.

Competition authorities therefore examine concentration under three main areas of competition law:

• merger control;
• abuse of dominance or monopolization; and
• anti-competitive agreements, including market allocation and bid coordination.

A concentrated waste market is not automatically unlawful. The important question is whether the structure or conduct substantially reduces competition—for example, by eliminating an important competitor, creating barriers to entry, facilitating coordination, or enabling higher prices or poorer service.

2. Relevant Market Definition

Market definition is particularly important in waste cases.

Product market

Authorities may distinguish between:

• residential waste collection;
• commercial waste collection;
• industrial waste collection;
• municipal waste collection contracts;
• recyclable-material collection;
• hazardous waste collection;
• non-hazardous waste collection;
• waste treatment;
• landfill services;
• incineration;
• recycling and materials recovery.

Collection and disposal should not automatically be treated as one market. A collection company may need access to independently owned landfills, transfer stations or recycling facilities.

Geographic market

Waste collection markets are frequently geographically narrow.

The U.S. Department of Justice has explained that solid-waste collection markets are generally local because transportation economics and political jurisdictions limit the areas in which haulers can compete effectively.

This means that even where many waste companies operate nationally, a particular city or region may still have only two or three realistic competitors.

3. Why Concentration Can Become a Competition Problem

Waste collection has several structural characteristics capable of producing concentration.

Economies of density are particularly significant. A company collecting from many customers located close together can normally operate more efficiently than a company whose customers are widely dispersed.

Entry can also require substantial investment in trucks, employees, depots, regulatory permits, insurance and access to treatment or disposal facilities.

Municipal contracts may create another barrier. Where one company receives an exclusive contract for several years, competitors cannot normally compete for the customers covered by that contract during its term. Competition therefore occurs primarily for the contract when the authority conducts its tender.

Vertical integration can further strengthen market power. A company controlling collection trucks as well as transfer stations, recycling facilities, incinerators or landfills may possess advantages over independent collectors.

Important Case Laws and Competition Decisions

1. United States v. Waste Management, Inc. and Deffenbaugh Disposal, Inc. (2015)

This U.S. Department of Justice case concerned Waste Management's proposed acquisition of Deffenbaugh Disposal.

The DOJ treated the transaction as a horizontal merger involving solid-waste collection activities.

The case illustrates an important competition-law principle: authorities do not necessarily examine waste management as one nationwide industry. They may identify individual local markets in which the merging companies are particularly important competitors.

Where two significant local haulers combine, customers can lose an important alternative bidder or supplier.

The case therefore demonstrates the relevance of:

• local market concentration;
• elimination of direct competitors;
• barriers to entry;
• customer alternatives; and
• structural remedies such as divestiture.

2. United States v. Republic Services, Inc. and Allied Waste Industries, Inc. (2000)

This was another major U.S. horizontal waste-industry merger case.

The Department of Justice challenged aspects of the transaction between Republic Services and Allied Waste Industries. The proceeding expressly involved refuse systems and waste collection and resulted in a consent judgment.

The case shows why national market shares may provide an incomplete picture.

Suppose Company A has only 10% of nationwide waste collection and Company B has 8%. Their combined national position might appear modest. But if they are two of only three effective suppliers in a particular metropolitan area, their merger could substantially increase concentration there.

Thus, competition analysis normally focuses on the competitive conditions experienced by actual customers.

3. European Commission — Veolia/Suez (Case M.9969)

The Veolia/Suez transaction is particularly important for understanding modern concentration analysis in environmental services.

Many services were supplied through competitive tenders. Consequently, the European Commission examined bidding information rather than relying solely on conventional market shares.

The Commission considered matters such as:

• the number of companies participating in tenders;
• how frequently Veolia and Suez competed against each other;
• the value of tenders;
• which competitors customers regarded as credible alternatives; and
• how concentration would change following the transaction.

The Commission's later merger analysis explains that some relevant markets were already concentrated and that the transaction could further reduce customers' choice of alternative suppliers.

This demonstrates that tender concentration can be as important as ordinary market-share concentration.

4. European Commission — Veolia/Cleanaway (Case COMP/M.4318)

Veolia/Cleanaway concerned Veolia's acquisition of Cleanaway and involved waste-management activities.

A competition complaint specifically raised concerns about municipal waste collection and related street-cleansing services in London. The allegation was that the parties had a significant position in municipal contracts and advantages associated with access to collection-vehicle depots.

The Commission investigated these concerns. The transaction ultimately proceeded subject to commitments addressing competition concerns identified during the broader merger investigation.

The case is useful because it demonstrates that concentration analysis extends beyond simple percentages. Authorities may examine physical infrastructure such as:

depots → vehicles → collection routes → disposal facilities.

Control over strategically located infrastructure can affect whether smaller competitors can compete effectively for municipal contracts.

5. State v. New Jersey Trade Waste Association (New Jersey Supreme Court, 1984)

This case provides an important example of concentration produced through coordination rather than merger.

The proceedings involved an alleged conspiracy among garbage collectors under which competitors would refrain from competing for each other's customers.

A practice known as “property rights” effectively treated existing customers as belonging to the collector already serving them. The New Jersey Supreme Court described the alleged arrangement as one designed to prevent garbage collectors from competing among themselves.

This illustrates the distinction between two forms of concentration:

Structural concentration occurs when only a few firms possess large market shares.

Behavioural suppression of competition occurs when firms that are formally independent agree not to compete.

Both can produce similar practical consequences: reduced customer choice and weaker price competition.

6. Waste Management of the Desert, Inc. v. Palm Springs Recycling Center, Inc. (California Supreme Court, 1994)

This case concerned the boundaries of an exclusive municipal waste franchise.

The City of Rancho Mirage had contracted with Waste Management for collection and disposal services. A dispute arose over whether the exclusive franchise could prevent another company from collecting recyclable materials.

The California Supreme Court held that the statutory authorization for exclusive solid-waste franchises did not extend to recyclable materials that had not been discarded by their owners.

The case is important to market-concentration analysis because exclusive municipal franchises can lawfully produce very high concentration within their authorized scope.

However, the precise boundaries of the franchise matter. An incumbent cannot necessarily extend exclusivity into neighboring activities merely because it already possesses exclusive waste-collection rights.

7. Stericycle, Inc. / Ecowaste Southwest Limited (UK OFT, 2011)

The UK Office of Fair Trading examined Stericycle's completed acquisition of Ecowaste Southwest.

The matter concerned waste-related services and was serious enough at the first stage to be referred for further merger investigation.

The case demonstrates the significance of specialized waste markets.

Ordinary household collection, commercial waste and specialized waste-management services may have different competitors and entry requirements. Consequently, authorities can define a relatively narrow product market where customers cannot readily substitute one service for another.

A merger may therefore raise concentration concerns in a specialized segment even though the broader waste industry contains numerous companies.

8. Cholet Acquisitions Ltd / Waste Recycling Group plc (UK OFT, 2003)

This transaction involved the acquisition of Waste Recycling Group, whose operations included receiving, processing, recycling and disposing of waste.

The OFT investigated the transaction under merger-control principles and ultimately cleared it at Phase 1.

This decision illustrates an equally important principle:

high involvement in the waste industry does not automatically establish an unlawful concentration.

Authorities must examine actual overlaps, competitive alternatives, entry possibilities and customer switching rather than assuming that every consolidation within the sector substantially reduces competition.

4. Measuring Concentration

Competition authorities commonly start with market shares and concentration measures such as the Herfindahl-Hirschman Index (HHI).

HHI is calculated by squaring each firm's percentage market share and adding the results.

For example, consider a local market with:

• Firm A — 40%
• Firm B — 30%
• Firm C — 20%
• Firm D — 10%

The HHI would be:

40² + 30² + 20² + 10² = 3,000.

But numerical concentration is only a starting point. Waste markets frequently require additional examination of tenders, routes, disposal infrastructure and entry conditions.

5. Tender-Based Concentration

Municipal waste collection frequently operates through competitive procurement.

Suppose five companies formally exist in a region, but examination of the previous 30 municipal tenders shows that only Companies A and B regularly submit credible bids.

The economically meaningful competitive structure may therefore be much narrower than the raw number of registered suppliers suggests.

The Veolia/Suez investigation illustrates this approach. Tender participation and bidding relationships were used to understand competitive intensity where conventional market-share information did not fully capture market conditions.

Authorities may therefore examine who bids, who wins, who competes against whom, bid values, frequency of participation and whether losing bidders represent realistic alternatives.

6. Exclusive Municipal Franchises

Waste collection creates an unusual distinction between competition in the market and competition for the market.

With ordinary commercial collection, several companies may compete continuously for customers.

With an exclusive municipal franchise, the successful company may become the sole provider for five or ten years. There is little or no competition within the covered territory during that period.

Competition instead occurs when companies bid for the franchise.

The DOJ has specifically recognized this distinction in describing solid-waste markets: exclusive franchises remove ordinary competition during the contractual term, although firms can compete periodically to obtain those franchises.

Therefore, a municipality having one waste collector does not by itself prove an antitrust violation.

The critical issue is how that exclusivity was created and maintained.

7. Vertical Concentration

Another concern arises when the same company controls several stages:

Collection → Transfer Station → Sorting → Recycling → Treatment → Landfill/Incineration.

This vertical integration can produce efficiencies because transportation and treatment can be coordinated.

However, competition problems can arise if control over essential downstream infrastructure makes it substantially harder for independent collection companies to compete.

For example, if only two economically accessible landfills exist and the dominant collection company purchases both, rival collectors may face increased disposal costs.

Thus authorities distinguish between efficiencies from integration and exclusionary effects on competitors.

8. Barriers to Entry

Several factors can protect concentrated waste markets:

Capital requirements. Trucks, containers and depots require substantial investment.

Route density. New entrants initially have fewer customers per route and therefore potentially higher collection costs.

Disposal access. Independent collectors may require affordable access to landfills, incinerators or transfer stations.

Regulation. Environmental permits and local licensing can delay entry.

Long contracts. Multi-year municipal contracts may leave few opportunities for new competitors.

Reputation and experience requirements. Public authorities may require previous experience or financial capacity.

These factors explain why the theoretical possibility that another waste company could enter does not necessarily establish that entry would effectively constrain a concentrated incumbent.

9. Competitive Harm

Excessive concentration can potentially lead to:

Higher prices: fewer alternatives can weaken customers' bargaining power.

Reduced service quality: weaker rivalry may reduce incentives to improve collection frequency, reliability or customer support.

Lower innovation: firms may have fewer incentives to introduce improved sorting, recycling or route-management technologies.

Tender problems: municipalities may receive fewer serious bids.

Foreclosure: vertically integrated companies may restrict competitors' practical access to disposal or processing infrastructure.

But these outcomes must normally be supported by evidence rather than inferred solely from market concentration.

10. Possible Efficiencies

Consolidation can also generate legitimate economic benefits.

A larger operator may achieve:

• greater route density;
• lower fuel and transportation costs;
• better utilization of trucks;
• centralized recycling facilities;
• improved logistics;
• investment in modern processing facilities; and
• lower per-unit collection costs.

Competition authorities therefore examine both potential competitive harm and merger-specific efficiencies.

The legal issue is generally not whether a company becomes “large,” but whether the transaction or conduct materially damages the competitive process under the applicable competition-law standard.

Conclusion

Waste collection market concentration is primarily a local competition problem. A national industry containing dozens of operators can still contain individual cities where only two or three companies represent realistic alternatives.

Cases such as United States v. Waste Management/Deffenbaugh, United States v. Republic Services/Allied Waste, Veolia/Suez, Veolia/Cleanaway, State v. New Jersey Trade Waste Association, Waste Management of the Desert v. Palm Springs Recycling Center, Stericycle/Ecowaste, and Cholet/Waste Recycling Group demonstrate the different ways competition law addresses this sector.
