In Paraguay, the pseudo stem of the banana tree is cut and broken after fruit annually, deposited in growing area for weathering. The wide availability of these pseudo stem  transforms them into a potential source of raw material for processing into pulp for paper, justifying a preliminary screen of your paper ability. The fresh pseudo stems were subjected  to a process for separating  the fibrous material, dried  in  the atmosphere and  the material obtained was  stored until use. First  tests were made  in  laboratory  some  alkaline  Cooking of  the material to evaluate the ranges of the operating variables: active alkali concentration, temperature and Cooking time and  the  appearance of the material obtained, and  then  tracking Cookings were  conducted at pilot plant horizontal rotary digester, with 10, 5 %AA 145 ° C for 45 minutes. The yield was determined  and  the drainability of  the pulp obtained  and prepared  in  the  laboratory  leaves was measured  tensile  resitence, RCT  (Ring Crush Test) and CMT  (Concora Meduim Test). He pulp yield is 54% of a typical chemical pulp and drainability of 215 mL CSF  stands at the  lower  threshold of cellulose pulp. The  tensile index with a value of 95 Nm/g corresponds to papers with high tensile resistance and RCT values of 215 N and 209 N CMT are satisfactory, and indicate that these  pastes can be used in fillings for papers to corrugate. These results are promising and justify performing an experimental design to optimize the process.
