I means that if we have special kind of waste that send to incineration or landfill, can we estimate what kind and how many pollution emission to air?(without measurement) just with Computing ؟
You can use LandGEM. It is a tool for estimation of emissions rates of total landfill gas, methane, carbon dioxide, nonmethane organic compounds, and individual air pollutants from municipal solid waste landfills.
You can use Environmental Impact Assessment tools to calculate emissions. There are special software designed specifically for LCA of wastes such as IWM.
