This study on Evaluation of Discharged Untreated Wastewater from Pulping and Bleaching operations in a Bamboo Based tissue Paper Making Plant Nigeria was conducted mainly to evaluate the pollutant loads present wastewater produced during paper making progression. The samples were obtained examined find out pollutants they contain by checking availability some physicochemical parameters using st...

Soda pulping was performed using kenaf stalk, core, and bast as raw materials. It was observed that all these components could yield good paper characteristics when the resulting pulps were beaten to a freeness of 200 to 300 mL. Soda pulp made from the stalk was comparable to the frond from oil palm in sheet properties, but the latter would require higher beating energy to reach similar freenes...

A tandem organosolv pulping and Pd-catalysed transfer hydrogenolysis depolymerisation and deoxygenation has been developed. The tandem process generated 2-methoxy-4-(prop-1-enyl)phenol in 23% yield (92% theoretical monomer yield) starting from pine wood and 2,6-dimethoxy-4-(prop-1-enyl)phenol in 49% yield (92% theoretical monomer yield) starting from birch wood. Only endogenous hydrogen from wo...

Intensive forest management, with a heavy emphasis on ecosystem management and restoring or maintaining forest health, will result in the removal of smaller diameter materials from the forest. This increases the probability of higher juvenile wood content in the harvested materials. The purpose of this study was to compare the performance of loblolly pine juvenile and mature wood unbleached the...

This research emerges from a growing concern to face the problem owing food loss (FL), with purpose evaluate processes in agro-industrial product elaboration, focusing on determination of critical points (FLCP) promote their further reduction. The was carried out Costa Rican MSME (micro, small and medium-sized enterprise), dedicated processing tropical fruits. FL assessment proposed methodology...

this study was devoted to the development of pulp luffa cclindrica and its characterization paper (annual plant fiber of the family cucurbitaceae). baking at soda helps to achieve a high level of delignification (kappa ≤ 10) and high yield (≈ 67%).the beatability stack valley is comparable to refined wood fibers, the fibers develop a normally time with good hydrophilic properties without excess...

chemical and morphological characterization of different parts of banana plant(musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. these segmented parts werecharacter...

a study was carried out on totally chlorine-free (tcf) bleachability of dimethyl formamide (dmf) treated bagasse pulps exposed to cz-3 and fp 90031-sp strains of white-rot fungus ceriporiopsis subvermispora. this process involved an oxygen and peroxide stage bleaching sequence. the effect of enzymatic stage on bleachability properties was studied and compared with control pulps, processed witho...

In kraft pulping, wood polysaccharides are subjected to the end-wise degradation (i.e., the peeling reaction) under alkaline conditions with the simultaneous formation of a large number of water/alkali-soluble hydroxy monoand dicarboxylic acids together with formic and acetic acids [1-3]. The versatile analysis of organic material in black liquor is of a great importance, for example, for monit...
