Paper sheets from Iranian olive tree produced by soda, sulphite and kraft pulping.Then the influence of pulp beating on properties of paper sheets was studied. Kraft pulp exhibited the highest holocellulose/yield -cellulose/yield ratios and the sulphite pulp the soda pulp the highest lignin/yield ratio. Paper sheets from kraft with the breaking length 5851 m, stretch 4.61%, Burst index 4.48 KN/...

This study investigated the mechanical properties and microstructural characteristics of fiberboard composite produced by naturally-bonded Malaysian bamboo fiber (Bambusa vulgaris). The components that obtained through soda pulping culms such as black liquor, were used for preparation high-density fibreboard at two target densities 850 950 kg/m3. (BFC) then 200°C pressing parameters 125 175 s/m...

Abstract To prevent virus spreading, the corpse or coffin of COVID-19 patients need to be wrapped in plastic. Low-density polyethylene (LDPE), a crude oil-based wrapping plastic, is difficult decompose nature after use. In this study, biocomposite film was developed from cassava starch and chitosan, with addition sorghum Micro-Fibrillated Cellulose (MFC) by levels 1%, 2%, 3%, 4% 5%. Cassava (ra...

Lignin, an amorphous biopolymer is one of the major components wood. In this study, lignin was extracted from Gmelina arborea wood using Soda and Kraft pulping processes. The characterized Fourier Transformed Infrared Spectrometer (FTIR), UV/visible spectrometer, electrospray ionization mass spectrometer scanning electron microscope (SEM). Results revealed that G. lignins contained several chem...
