What is the cascade use principle for timber?

Cascade use is the principle of using timber in its highest-value application first, then progressively moving to lower-value uses as the material degrades or becomes unsuitable for its current function. The hierarchy is: structural use → reuse as structural → reuse as non-structural → remanufacture into panels/boards → biomass for energy → landfill (last resort).

Each cascade step extends the carbon storage period and maximises the total value extracted from the original forest resource.
