Municipal Solid Waste Resources and Technologies

The National Renewable Energy Laboratory's high-solids digester converts wastes to biogas and compost for energy production.

This page provides a brief overview of municipal solid waste energy resources and technologies supplemented by specific information to apply waste to energy within the Federal sector.


Municipal solid waste, also known as waste to energy, generates electricity by burning solid waste as fuel. This generates renewable electricity while also incinerating landfill and other municipal waste products such as trash, yard clippings and debris, furniture, food scraps, and other discarded items.

The U.S. currently uses two waste to energy facility designs:

Incinerating municipal solid waste generates energy while reducing waste volumes by as much as 90% with ash disposal and air polluting emissions as the primary environmental impacts. Effective environmental management is needed to remove toxins prior to combustion to minimize pollutants.

Federal Application

Before conducting an assessment or deploying energy technologies, Federal agencies must evaluate a series of questions.

What are my energy goals?

Energy goals range from meeting regulatory requirements to powering remote applications to increasing energy security.

What kind of energy do I use?

Federal agencies must understand what type of energy is used before determining if municipal solid waste is applicable. Municipal solid waste can be used for electricity production.

When do I need the energy?

Even with substantial recycling and reuse programs, municipal solid waste is inevitable in most communities. As such, it is a dependable and predictable resource that can typically be used on-demand, around the clock.

How much power do I use/need to produce?

Municipal solid waste technologies generate varying amounts of electricity depending on the size of both the technology deployment and urban area itself. It is important to consult an expert for a professional evaluation to plan accordingly.

Where am I located?

Before initiating a project, resources in your area must be measured and verified. It is important to consult an expert for a professional evaluation before implementing municipal solid waste energy projects.

Is a landfill available?

Municipal solid waste energy applications are dependent on landfill and other urban waste resources. For this application, Federal facilities should be in close proximity to local landfills. The steam plant should be within 1 mile if steam is being transferred from the municipal solid waste plant to a Federal facility. If the waste is being transported to the Federal facility as fuel, the distance will vary depending on the volume and quality of fuel needed. Typically, a 100 mile or less collection radius is necessary. Be sure to check with facility resources, as well as municipal and county landfill contacts, to see if implementing municipal solid waste technologies is possible for your facility.

Is this a building- or campus-scale project?

Municipal solid waste renewable energy technologies are well suited at the campus level. Implementing a municipal solid waste system for a standalone building or facility is typically not cost-effective.

What is my budget?

It is important to consult an expert for a professional evaluation to see if municipal solid waste energy fits into your current budget.

What resources are available for operations and maintenance?

Municipal solid waste technologies require ongoing operations and maintenance. It is important to factor these operations and maintenance costs and staffing needs in any facility energy management plan.
