Landfill Gas Emissions Model
Description
Excel based model to estimate generation and emission rates for total landfill gas, methane, carbon dioxide, non methane organic compounds (NMOCs), and other hazardous air pollutants (HAPS) from municipal solid waste (MSW) landfills.
Questions this resource can help answer
- What is the amount and rate of methane and non-methane pollution emitted by municipal solid waste landfills?
- Which Clean Air Act control requirements is a specific landfill subject to?
How do I use this resource?
The spreadsheet model allows a user to enter landfill characteristics such as year when landfill was opened and annual tons of waste added. User then selects a methane gas generation value, reviews the pollutant gas concentrations for non-methane pollutants. The model then calculates methane, landfill gas, and non-methane pollutant generation.
Resource information
Technical specifications
Model uses first-order decay kinetics to simulate landfill gas generation and emissions. The model applies methane generation factors to waste masses at landfills to predict the annual mass of methane formed. Other hazardous air pollutants are estimated using concentration rates based on AP42 emissions factors
