Landfill GasMethane gas that forms in landfills from the decay of organic materials. The gas can be collected and used for power generation.
ligninA group of high-molecular-weight amorphous polymers of phenylpropanoid compounds, giving strength to certain tissues. A major component of wood.
lignin pseudo-molecule for modelingThe lignin ratio of methoxy groups to phenylpropanoid groups (MeO:C9) is used to calculate an ultimate analysis for the lignin pseudo-molecule.
lignin ratio of MeO to C9Lignin empirical formulae are based on ratios of methoxy groups to phenylpropanoid groups (MeO:C9).
lignocelluloseThe combination of lignin, hemicellulose and cellulose that forms the structural framework of plant cell walls.
lower heating value (LLV)The heat produced by combusting one unit of a substance, at atmospheric pressure under conditions such that all water in the products remains in the form…
