Paper is a major product of the forestry industry, and is used widely in our society. Paper products are used not only in their obvious applications in the publishing industry and for writing on, but also in a variety of specialty papers, cardboard, brown papers etc.
Paper is made from wood using the “Kraft” process. This is a part mechanical, part chemical process that produces a strong pulp. It has several disadvantages, in terms of complexity and set up costs as well as having a low pulp yield and producing unpleasant-smelling sulphur compounds, but it is still internationally the most widely used pulp and paper process.
Wood derivatives dissolved in the pulping liquors, including oligosaccharides, simple sugars, low-molecular-weight lignite derivatives, acetic acid and solubilized cellulose fibres, are the main contributors to both biological oxygen demand (BOD) and chemical oxygen demand (COD).
