Production of Medium Density Fibreboard (MDF) from a mix of softwoods involves steam treatment and physical degradation of raw-materials to produce wood fibre for bonding. While the process is typically energy-efficient, using waste materials for steam generation, there may be an excess of wood wastes. In addition, effluent from washing and wood chips has to be treated. This involves a multistage process of filtration, Dissolved Air Flotation (DAF) and Activated Sludge processing. The mixed waste solids are typically belt-pressed and disposed to land-fill.
