OrganEcs - Cost estimating tool for managing source-separated organic waste


Organic waste management (i.e., composting and anaerobic digestion) represent a key opportunity for achieving the reduction of short-lived climate pollutants from the municipal solid waste sector. Planning and developing such projects require a detailed understanding of the costs involved in constructing and operating organic waste management facilities.

OrganEcs is an Excel-based tool for estimating the costs, revenues, and potential profitability associated with an organic waste management project. It provides planning-level assistance to local governments, waste professionals, policymakers, facility operators, and project developers to help them make financial decisions about their potential organic waste management projects.

OrganEcs was developed by the U.S. Environmental Protection Agency under the auspices of the Global Methane Initiative and in support of the Climate and Clean Air Coalition.
