Summary
The Pulp and Paper Department of the INPA (Instituto Nacional de Pesquisas da Amazonia) has undertaken to realize a systematic study on Brazilian hardwoods from the Amazon region and selecting the best ones for further research. The first one in this series is Marupa (Simaruba amara — Aubl.) and was done by INPA's Pulp and Paper Department's technicians at the Laboratories of the Cellulose Division of the Centre Technique Forestier (Nogent Sur Marne — France) in a technical cooperation program. Data on the chemical pulping are given and also on trials with high yield pulps by the soda and the neutral sulphite precesses. Marupa is concluded to be an interesting papermaking species for reforestation.
