Item 2. Properties.
Our principal executive offices are in Houston, Texas where we lease approximately 285,000 square feet under a lease expiring in 2035. We also have administrative offices in Arizona, Connecticut, Illinois, India and parts of Western Europe. We own or lease real property in most locations where we have operations or administrative functions. We have operations (i) in all 50 states; (ii) in the District of Columbia; (iii) parts of Canada and (iv) parts of Western Europe.
Our principal property and equipment consist of land (primarily landfills and other disposal facilities, transfer stations and bases for collection operations), buildings, vehicles and equipment. We believe that our operating properties, vehicles and equipment are adequately maintained and sufficient for our current operations. However, we expect to continue to make investments in additional property and equipment for expansion, for the replacement of aging assets and investment in assets that support our strategy of continuous improvement through efficiency and innovation. In addition, we continue to make progress on our planned investments to expand our Recycling Processing and Sales and WM Renewable Energy segments. As of December 31, 2024, we had 102 landfill gas beneficial use projects producing commercial quantities of methane gas at owned or operated landfills. For 65 of these projects, the processed gas is used to fuel electricity generators. The electricity is then sold to public utilities, municipal utilities or power cooperatives. For 23 of these projects, the gas is used at the landfill or delivered by pipeline to industrial customers as a direct substitute for fossil fuels in industrial processes. For 11 of these projects, the landfill gas is processed to pipeline quality RNG and then sold to natural gas suppliers. Additionally, three of these projects are on third-party landfills. For more information, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations included within this report.
