Wood industry continues to grow at a national and international scale producing considerable quantities of waste and related products such as branches, bark and sawdust. This considerable increase in waste pushed scientists to discover new methods for their valorisation, namely: energetic, for use as fuel, organic for the manufacture of composts and fertilizers and recycling materials for the manufacture of pulp, chipboard, etc. chemical treatment which we realized, during our work has resulted in the production of a pulp which contains cellulosic fibers. This treatment has several advantages as it allows using a minimum of chemical products and a simpler protocol. The present paper analyses the environmental aspects of resource recovery from chemically treated wood products (furniture, etc.). A life cycle assessment model of wood waste processing method in laboratory conditions is developed. Life cycle inventory is based on the data of laboratory experiments gathered in the laboratory of applied chemistry, Faculty of Science and Technology, University of Sidi Mohammed Ben Abdellah in Morocco. The analysed system boundary includes the collected wood waste after the first end of life, their transportation to the treatment plant, the chemical treatment and the final product. The result of assessment describes the environmental aspects of the analysed treatment method and the recommendations of further analysis proposed.
