the objective of this paper is a focused review on the selected processes for a particular approach to biorefinery: incremental deconstruction of woody biomass in the absence of waste generation steps such as pretreatment and detoxification. In particular, integrated studies on hot-water based biochemical approach is systematically reviewed. In particular, hot-water extraction based “pretreatment” processes are discussed in detail.
