Who should attend

This course should provide sufficient information for graduated technical staff to get a good knowledge of the wood pulping processes, to understand the basic principles governing the different operations and to identify the key factors influencing pulp yield and quality.

Those interested in wood biorefinery opportunities around cellulose production units will find the key elements which must be understood to develop their projects.
