Four of these wood species have been pulped by the sulphate process: "bracatinga" (Mimosa bracatinga), "embauba" (Cecropia sp.), "caixeta" (Tabebuia cassinoides) and "boleira" (Joannesia princeps). Pulp qualities were inferior to those obtained from Eucalyptus saligna pulpwood, however the pulps are good enough for printing and writing paper manufacture.  awood  aCelulose  aEspécie Nativa  aMadeira  aCelluloses  aIndigenous organisms1 aFOELKEL, C.
