Pulp and paper from blue agave waste from tequila production
(1999)
Pulping of blue agave waste, from the production of tequila, was evaluated by both chemical and biomechanical pulping processes. Two conventional and two organosolv systems were used to pulp the agave waste under a standard ...
Effect of accelerated carbonation on cementitious roofing tiles reinforced with lignocellulosic fibre
(ELSEVIER SCI LTD, 2010)
The present work evaluated the effects of accelerated carbonation on mechanical and physical characteristics of cementitious roofing tiles reinforced with vegetable fibre. The maximum load and toughness of the tiles have ...

Production of xylanase by Aspergilli using alternative carbon sources: application of the crude extract on cellulose pulp biobleaching
(SPRINGER HEIDELBERG, 2009)
The ability of xylanolytic enzymes produced by Aspergillus fumigatus RP04 and Aspergillus niveus RP05 to promote the biobleaching of cellulose pulp was investigated. Both fungi grew for 4-5 days in liquid medium at 40A ...
Xylanases from Aspergillus niger, Aspergillus niveus and Aspergillus ochraceus produced under solid-state fermentation and their application in cellulose pulp bleaching
(SPRINGER, 2009)
This study describes the production of xylanases from Aspergillus niveus, A. niger, and A. ochraceus under solid-state fermentation using agro-industrial residues as substrates. Enzyme production was improved using a mixture ...
Evaluation of acid stage and of hydrogen peroxide on alkaline extraction of eucalyptus kraft pulp
(2017-01-01)
The Elemental Chlorine Free (ECF) bleaching technology is very well established for kraft pulp bleaching due to its efficiency in bleaching processes, once it presents high brightness, besides low reversion. In this work ...
