PART I

Item 1.     Business.

General

      The financial statements in this report represent the consolidation of Waste Management, Inc., a Delaware corporation, its majority-owned subsidiaries and entities required to be consolidated pursuant to the Financial Accounting Standards Board’s (“FASB”) Interpretation No. 46, Consolidation of Variable Interest Entities (“FIN 46”). Waste Management, Inc. is a holding company that conducts all of its operations through its subsidiaries. The terms “the Company,” “we,” “us” or “our” refer to Waste Management, Inc. and its consolidated subsidiaries.

      We are the leading provider of integrated waste services in North America. Through our subsidiaries we provide collection, transfer, recycling and resource recovery, and disposal services. We are also a leading developer, operator and owner of waste-to-energy facilities in the United States. Our customers include commercial, industrial, municipal and residential customers, other waste management companies, electric utilities and governmental entities. During 2003, none of our customers accounted for more than 1% of our operating revenue. We employed approximately 51,700 people as of December 31, 2003.

      Our parent company was incorporated in Oklahoma in 1987 under the name “USA Waste Services, Inc.” and was reincorporated as a Delaware company in 1995. In a 1998 merger, Waste Management, Inc. became a 100% owned subsidiary and changed its name to Waste Management Holdings, Inc. At the same time, our parent company changed its name to Waste Management, Inc. Our principal executive offices are located at 1001 Fannin Street, Suite 4000, Houston, Texas 77002. Our telephone number at that address is (713) 512-6200. Our website address is http://www.wm.com. Our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K are all available, free of charge, on our website as soon as practicable after we file the reports with the SEC. Our stock is traded on the New York Stock Exchange under the symbol “WMI.”

Strategy

      Our goals are operational excellence and financial strength, which we seek by concentrating on (i) providing excellent customer service, (ii) lowering costs, (iii) increasing cash flow and (iv) maintaining our credit ratings at investment grade. We focus and continue to make progress on the following key initiatives:

  •  Asset Utilization — Implementing and updating integrated local business strategies for our operations, including collection, disposal (including waste-to-energy plants), and transfer, to achieve benefits of integrated operations and to improve our overall utilization of our asset base;
 
  •  Service Excellence — Designing and implementing new ways to better meet our customers’ requirements;
 
  •  Economies of Scale and Cost Efficiencies — Continuing to implement a procurement and sourcing process that leverages our size and total purchasing ability to realize savings through consolidation and reduction of the number of suppliers;
 
  •  Price/ Revenue Management — Improving our pricing analysis capabilities, and developing and implementing new revenue management systems;
 
  •  Sales Force Effectiveness — Providing tools, leadership and incentives throughout our organization designed to enable and encourage our sales force to improve its effectiveness and increase revenue; and
 
  •  Shareholder Value — Enhancing shareholder value through share repurchases, increased cash dividends, emphasizing earnings and cash flow growth, and maintaining a strong, liquid and flexible financial condition. We strive to maintain close relationships with shareholders, banks, bondholders,

  credit rating agencies, surety companies and regulators to ensure adequate access to a variety of capital markets and funding sources.

Operations

 
General

      We manage and evaluate our operations through seven operating Groups, five of which are organized by geographic area and the other two of which are organized by function. The geographic Groups include our Eastern, Midwest, Southern, Western and Canadian Groups, and our two functional Groups are the Recycling and Wheelabrator Groups. In 2002, we reorganized our operations to form market areas within the geographic Groups that are responsible for the sales, marketing and delivery of our services. We believe that this structure, which resulted in the elimination of one layer of field operations and two layers of administrative and support staff, better aligns our collection, transport, recycling and disposal resources. Additionally, we believe that the geographic structure results in a better use of our resources and more efficient service to our customers. We manage and evaluate our business through the seven Groups, which represent our reportable segments.

      These reportable segments, when combined with certain other operations not managed through any of the seven Groups, comprise our North American Solid Waste, or NASW, operations. NASW, our core business, provides integrated waste management services consisting of collection, disposal (solid and hazardous waste landfills), transfer, waste-to-energy facilities and independent power production plants that are managed by Wheelabrator, and recycling and other miscellaneous services to commercial, industrial, municipal and residential customers throughout the United States, Puerto Rico and Canada. The operations not managed through our seven Groups, which include methane gas recovery, rentals, in-plant services and other miscellaneous services, are presented in this report as “Other NASW.”

      Until December 31, 2001 our operations included waste management operations in Mexico and certain countries outside of North America and until March 31, 2002 included non-solid waste operations. These divested operations are presented in this report as “Other.” Although we no longer hold any revenue generating assets related to the Other operations, we continue to incur minimal administrative expenses in connection with these divested operations.

      The table below shows the total revenues (in millions) contributed annually by each of our reportable segments in the three-year period ended December 31, 2003. The 2002 and 2001 information has been restated to conform to the current year presentation, which includes our newly formed Recycling Group. More information about our results of operations by reportable segment is included in Note 20 to the consolidated financial statements and in the Management’s Discussion and Analysis of Financial Condition and Results of Operations included in this report.

      Collection. Our commitment to customers begins with a vast waste collection network. Collection involves picking up and transporting waste from where it was generated to a transfer station or disposal site. We generally provide collection services under two types of arrangements:

  •  For commercial and industrial collection services, generally we have a one to three-year service agreement. The fees under the agreements are influenced by factors such as collection frequency, type of collection equipment furnished by us, type and volume or weight of the waste collected, distance to the disposal facility, labor costs, cost of disposal and general market factors. As part of the service, we provide steel containers to most of our customers to store their solid waste between pick-up dates. Containers vary in size and type according to the needs of our customers or restrictions of their communities and are designed so that they can be lifted mechanically and either emptied into a truck’s

3


 

  compaction hopper or directly into a disposal site. By using these containers, we can service most of our commercial and industrial customers with trucks operated by only one employee.
 
  •  For most residential collection services, we have a contract with, or a franchise granted by, a municipality or regional authority that gives us the exclusive right to service all or a portion of the homes in an area. These contracts or franchises are typically for one to five years, but can sometimes be longer. We also provide services under individual monthly subscriptions directly to households. The fees for residential collection are either paid by the municipality or authority from their tax revenues or service charges, or are paid directly by the residents receiving the service.

      Landfill. Landfills are the main depository for solid waste in North America and we have the largest network of landfills in North America. Solid waste landfills are built and operated on land with geological and hydrological properties that limit the possibility of water pollution, and are operated under prescribed procedures. A landfill must be maintained to meet federal, state or provincial and local regulations. The operation and closure of a solid waste landfill includes excavation, construction of liners, continuous spreading and compacting of waste, covering of waste with earth or other inert material and constructing final capping of the landfill. These operations are carefully planned to maintain sanitary conditions, to maximize the use of the airspace and to prepare the site so it can ultimately be used for other purposes.

      All solid waste management companies must have access to a disposal facility, such as a solid waste landfill. We believe it is usually preferable for our collection operations to use disposal facilities that we own or operate, which we refer to as internalization, rather than using third party disposal facilities. Internalization generally allows us to realize higher consolidated margins and stronger operating cash flows. The fees charged at disposal facilities, which are referred to as tipping fees, are based on market factors and the type and weight or volume of solid waste deposited.

      We also operate secure hazardous waste landfills in the United States. Under federal environmental laws, all hazardous waste landfills must be permitted by the federal government. All of our hazardous waste landfills have obtained the required permits although some can accept only certain types of hazardous waste. These landfills must also comply with specialized operating standards. Only hazardous waste in a stable, solid form, which meets regulatory requirements, can be deposited in our secure disposal cells. In some cases, hazardous waste can be treated before disposal. Generally, these treatments involve the separation or removal of solid materials from liquids and chemical treatments that transform wastes into inert materials that are no longer hazardous. Our hazardous waste landfills are sited, constructed and operated in a manner designed to provide long-term containment of waste. We also operate a hazardous waste facility at which we isolate treated hazardous wastes in liquid form by injection into deep wells that have been drilled in rock formations far below the base of fresh water to a point that is separated by other substantial geological confining layers.

      We owned or operated 284 solid waste and five hazardous waste landfills at December 31, 2003 compared with 288 solid waste landfills and five hazardous waste landfills at December 31, 2002. The landfills that we operate but do not own are generally operated under a lease agreement or an operating contract. The differences between the two arrangements usually relate to the owner of the landfill operating permit. Generally, with a lease agreement, the permit is in our name and we operate the landfill for its entire life and make payments to the lessor, who is generally a private landowner, based either on a percentage of revenue or a rate per ton of waste received. We are generally responsible for closure and post-closure requirements under our lease agreements. For operating contracts, the owner of the property, generally a municipality, usually owns the permit and we operate the landfill for a contracted term, which may be the life of the landfill. The property owner is generally responsible for closure and post-closure obligations under our operating contracts.

      Based on remaining permitted capacity as of December 31, 2003 and projected annual disposal volumes, the weighted average remaining landfill life for all of our owned or operated landfills is approximately 26 years. Many of our landfills have the potential for expanded disposal capacity beyond what is currently permitted. We monitor the availability of permitted disposal capacity at each of our landfills and evaluate whether to pursue an expansion at a given landfill based on estimated future waste volumes and prices, remaining capacity and likelihood of obtaining an expansion. We are currently seeking expansion permits at 84 of our landfills for which we consider expansions to be probable. Although no assurances can be made that all future expansions

4


 

will be permitted as designed, the weighted average remaining landfill life for all owned or operated landfills is approximately 36 years when considering remaining permitted capacity, probable expansion capacity and projected annual disposal volume. At December 31, 2003 and 2002, the expected remaining capacity in cubic yards and tonnage of waste that can be accepted at our owned or operated landfills is shown below (in millions):

(a) Amount provided for 2003 includes changes in the landfill capacity related to three newly permitted landfill sites and the divestiture of one landfill operated under contract.
 
(b) Changes in engineering estimates result in either changes to the available remaining landfill capacity in terms of volume or changes in the utilization of such landfill capacity, affecting the number of tons that can be placed in the future. The majority of the increase in capacity during 2003 resulting from changes in engineering estimates is due to an increase in the estimated tons per cubic yard that can be placed in our remaining landfill airspace. Estimates of the amount of waste that can be placed in the future are reviewed annually by our engineers and are based on a number of factors, including standard engineering techniques, historical data and improvements in landfill operational procedures. We continually focus on improving the utilization of airspace through efforts that include recirculating landfill leachate where allowed by permit, optimizing the placement of daily cover materials and increasing initial compaction through improved landfill equipment, operations and training. Additionally, future airspace utilization may be affected by changes in the types of waste materials received at our landfills.

     The estimated operating lives, based on remaining permitted and probable expansion capacity and projected annual disposal volume (in years) as of December 31, 2003, is as follows:

(a) We closed three landfills in 2003; successfully permitted three new landfills; and had a net decrease in operating contracts of four, including one that was divested. We also had one landfill previously operated under contract that has been reclassified as owned.
 
(b) This amount includes approximately 1.1 million tons that were received at our landfills but were used for beneficial purposes, generally redirected from the permitted airspace to other areas of the landfill. Waste types that are frequently identified for beneficial use include green waste for composting and clean dirt for on-site construction projects.
 
(c) This amount includes approximately 1.2 million tons that were received at our landfills but were used for beneficial purposes, generally redirected from the permitted airspace to other areas of the landfill. Waste types that are frequently identified for beneficial use include green waste for composting and clean dirt for on-site construction projects.

     When a landfill we own or operate (i) reaches its permitted waste capacity, (ii) is permanently capped and (iii) receives certification of closure from the applicable regulatory agency, management of the site, including any remediation activities, is generally transferred to our closed sites management group. At December 31, 2003, we manage 173 closed landfills, most of which are managed by our closed sites management group.

      Transfer. Transfer stations are located near residential and commercial collection routes where collection trucks take the solid waste that has been collected. The solid waste is then consolidated and transported by transfer trucks or by rail to disposal sites. Fees at transfer stations are usually based on the type and volume or weight of the waste transferred, the distance to the disposal site and general market factors. At December 31, 2003, we owned or operated 366 transfer stations in North America. There are two main reasons for using transfer stations:

  •  Transfer stations reduce the cost of transporting waste to disposal sites because transfer trucks, railcars or rail containers have larger capacities than collection trucks, allowing us to deliver more waste to the disposal facility in each trip. Waste is also often compacted at transfer stations, which in addition to the consolidation of the waste, increases the efficiency of our collection personnel and equipment because they are able to focus on collection activities rather than making trips to the disposal sites.
 
  •  Transfer stations improve internalization by allowing us to retain fees that we would otherwise pay to third parties to dispose of waste we collect. A greater percentage of the waste we collect can be disposed of at one of our own disposal sites because the waste coming into one of our transfer stations will usually be taken to one of our own disposal facilities. Additionally, more waste is internalized because the transfer vehicles can transport waste longer distances to one of our disposal facilities.

      The transfer stations that we operate but do not own are generally operated through lease agreements under which we lease property from third parties. There are some instances where transfer stations are operated under contract, generally for municipalities. In most cases we own the permits and will be responsible for all of the regulatory requirements in accordance with the lease and operating agreement terms.

      Wheelabrator. Through Wheelabrator, we own or operate 17 waste-to-energy facilities that accept solid waste for disposal. Fees at our waste-to-energy facilities are influenced by the market rates for electricity, type and volume of waste received and other general market factors. Our waste-to-energy facilities are capable of processing up to 24,250 tons of solid waste each day. In 2003, our waste-to-energy facilities received

6


 

approximately 7.7 million total tons, or approximately 21,200 tons per day, compared to approximately 7.5 million total tons, or approximately 20,700 tons per day, in 2002. The solid waste is burned at high temperatures in specially designed boilers at these facilities, producing heat that is converted into high-pressure steam. We use that steam to generate electricity for sale to electric utilities under long-term contracts. Our waste-to-energy facilities can generate up to an aggregate of 690 megawatts (“mW”) of renewable electricity per hour.

      Our Wheelabrator operations also include six independent power production plants that convert various waste and conventional fuels into electricity and steam. Fees at our independent power production plants are influenced by the market rates for electricity and steam, type and volume of waste received and other general market factors. The plants burn wood waste, anthracite coal waste (culm), tires, landfill gas and natural gas. These facilities are integral to the solid waste industry, disposing of urban wood, waste tires, railroad ties and utility poles. Our anthracite culm facility in Pennsylvania processes the waste materials left over from coal mining operations from over half a century ago. Ash remaining after burning the culm piles at the facility is used to reclaim the land damaged by decades of coal mining. In addition to electricity production, the plants also produce steam, which is sold to industrial and commercial users. The plants can produce a total of 246 mW of electricity per hour.

      Recycling. Our Recycling Group is comprised of Recycle America Alliance, L.L.C. (“RAA”). RAA was formed in January 2003 to improve the sustainability and future growth of recycling programs and includes certain recycling assets transferred from our geographic operating Groups as well as assets contributed by the Peltz Group, who maintains approximately nine percent of the equity interest in RAA. In addition to our Recycling Group, our five geographic operating Groups provide certain recycling services. The recycling services provided by other than RAA are generally those which are embedded within the Groups’ other operations and therefore were not transferred to RAA.

      Recycling involves the separation of reusable materials from the waste stream for processing and resale or other disposition. Our recycling operations include the following:

        Collection and materials processing — we collect recyclable materials from residential, commercial and industrial customers and direct these materials to a material recovery facility (“MRF”) for processing. We operate 138 MRFs where paper, glass, metals, plastics and compost are recovered for resale. We also operate 16 secondary processing facilities where materials received from MRFs can be further processed into raw products used in the manufacturing of consumer goods. Specifically, material processing services include data destruction, shredding, automated color sorting, composting, and construction and demolition processing.
 
        Glass recycling — using state-of-the-art sorting and processing technology, we remove contaminants from color-separated glass to produce and market furnace-ready cullet (crushed and cleaned post-consumer glass used to make new glass products). Our innovative glass processing capabilities increase material recovery and overall product quality.
 
        Plastics and rubber materials recycling — using state-of-the-art sorting and processing technology, we process, inventory and sell plastic and rubber commodities making the recycling of such items more cost effective and convenient.

produces landfill gas. The methane component of the landfill gas is a readily available, renewable energy source that can be gathered and used beneficially as an alternative to fossil fuel for a number of industrial and commercial applications. We actively pursue landfill gas beneficial use projects and at December 31, 2003 are producing commercial quantities of methane gas at 85 of our solid waste landfills. For 54 of these landfills, the processed gas is delivered to electricity generators. The electricity is then sold to public utilities, municipal utilities or power cooperatives. For 29 landfills, the gas is delivered by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes such as steam boilers, cement kilns and utility plants. At the remaining two landfills, we further process the gas to pipeline-quality natural gas, and then we sell it to natural gas suppliers.

      In addition, as part of our other operations, we rent and service portable restroom facilities to municipalities and commercial customers under the name Port-O-Let®, and provide street and parking lot sweeping services. We also provide in-plant services, in which we outsource our employees to provide full service waste management to customers at their plants. Our vertically integrated waste management operations allow us to provide these customers with full management of their waste, including finding recycling opportunities, minimizing their waste, determining the most efficient means available for waste collection and transporting and disposing of their waste.

Competition

      The solid waste industry is very competitive. Competition comes from a number of publicly-held solid waste companies, private solid waste companies, and large commercial and industrial companies handling their own waste collection or disposal operations. We also have competition from municipalities and regional government authorities with respect to residential and commercial solid waste collection and solid waste landfills. The municipalities and regional governmental authorities can subsidize the cost of service through the use of tax revenues and tax-exempt financing and therefore have a competitive advantage.

      Operating costs, disposal costs and collection fees vary widely throughout the geographic areas in which we operate. The prices that we charge are determined locally, and typically vary by the volume and weight, type of waste collected, treatment requirements, risk of handling or disposal, frequency of collections, distance to final disposal sites, labor costs and amount and type of equipment furni
