Purpose of the project In thejndustrial extraction of pulp from wood, it has been common practise for many years to recoverthe cooking chemicals and energyfrom the waste liquor produced during the cooking It is an obvious step to use this chemical recovery method, which has proven successful in wood processing, in the production of pulp from annuals as well. For many countries which do not have sufficient wood available, bamboo, bagasse, rice or wheat straw form an important basis for pulp production. One unique characteristic of these annuals is their high silicic acid content (5,) as compared to that of wood. In the sulp
