Long term landfill settlement is commonly attributed to two phenomena: creep and biodegradation. Biodegradation, which may contribute the greater proportion of long‐term settlement, is a function of a range of factors, many of which are not easily associated with conventional geomechanical analysis. A more fundamental treatment of biodegradation effects within the constitutive framework of a hydro‐bio‐mechanical (HBM) model is presented in this paper. The role of a decomposition‐induced void volume change parameter Λ, and its ability to handle biodegradation‐related settlement, are revealed through the simulation of a long‐term, laboratory‐scale waste settlement test.
