“…The bulk density for the SD used was 199 Kg/m 3 . The value ranged from 349.9 and 1031.7 Kg/m 3 from previous works (Ikenyiri et al, 2019) depending on the type of wood from which SD was derived. The sample used in the present work is lighter probably due to its level of dryness.…”

The Particle board (PB) was developed using Rice Husk (RH) and Sawdust (SD) with Gum Arabic (GA) resin as binder. The aim of the research work was to explore the engineering viability of GA bonded particle board made from agro-industrial wastes for sustainable environment. It was also to investigatealternative to the high-in-demand conventional particle board made from wood and urea melamine or amino-formaldehyde which is known to be carcinogenic. The RH/GA/SD materials used to produce samples were cheap and locally sourced. For the experiment, the rice husk (RH) content was kept constant although at 65%but the sawdust (SD) and gum arabic (GA) were varied at percentage levels of 5/30%, 10/25%, 15/20%, 20/15%, and 25/10%. After characterization the density of the Pb samples ranged from 447.71 Kg/m3 to 698.84Kg/m3. The compressive, split tensile and flexural strengths ranged from 2.24 to 23.31N/mm2, 1.52 to 3.04 N/mm2 and 1.776 to 4.752N/mm2 respectively. Modulus of elasticity ranged from 33.20 to 158.4N/mm2. The results showed that all the mechanical parameters tested met the requirement of the standards, except for moisture intrusion. The maximum value of water absorption was 7.62% for 2 minutes’ immersion in water as against 0.66% and 3.45% in 12 minutes recommended by European standards. The produced particle board is considered structurally viable in that at its ultimate strength it can serve as load-bearing in spite of relatively low density. To mitigate against water absorption, use of wax, veneer and paints can be introduced.

“…1(1): e150 ( 2022). e-ISSN: 2810-8736 que son semejantes a los obtenidos por Espinal-Corrales ( 2009) y superiores a los reportados por Ikenyiri et al (2019). El alto contenido de taninos, observado en las cortezas de caoba y cedro, muestran que estos residuos son una materia prima potencial para la obtención de taninos, pero el impedimento es que estas especies maderables son muy cotizadas, están bastante controladas e impedidas para su explotación.…”

La industria maderera en la región de Madre de Dios, Perú, es una de las actividades económicas más importantes y produce gran cantidad de residuos, entre ellas las cortezas, fuentes potenciales de taninos. El objetivo fue extraer y caracterizar fisicoquímicamente los taninos de la corteza de caoba (Swietenia macrophylla) y cedro (Cedrela odorata) colectados de árboles maduros, en poblaciones localizadas del distrito de Tambopata - Madre de Dios. Los extractos tánicos fueron obtenidos por extracción sucesiva con solución acuosa salina, y sometidos a análisis para determinar su solubilidad, color, densidad y pruebas de identificación compuestos tánicos. Los resultados mostraron que la corteza de caoba presentó mayor concentración de taninos que la del cedro, alcanzando ambos 46% y 42%, respectivamente; además, el extracto tánico de la corteza de cedro presentó densidad de 0,972 g/mL y la de caoba un 0,976 g/mL. En conclusión, las cortezas de caoba y cedro son fuentes potenciales de taninos del tipo pirogálicos para la industria de productos naturales.

Activated carbon from sawdust was prepared and characterized using Fourier transform infra-red (FTIR) and scanning electron microscope (SEM) to determine the presence of functional groups and visualize its microstructural arrangement in other to ascertain its potential for the removal of Mn 2+ ion from aqueous solution. Statistical design of experiment (DOE) using central composite design was then employed to randomized the levels of selected input parameters in order to determine their optimum values that will guarantee maximum adsorption. To optimize the process, response surface methodology based on numerical optimization was employed. The behaviour of the system which was used to evaluate the relationship between the input and the response variables was explained using the empirical second-order polynomial equation. To validate the optimization results, selected goodness of fit statistics, namely; coefficient of determination, adjusted coefficient of determination and predicted coefficient of determination were employed. Results obtained revealed the adequacy of response surface methodology in optimizing adsorption systems. Analysis of variance test revealed that the model developed is significant at 0.05df with computed p-value < 0.0001. Computed goodness of fit statistics revealed that the predicted R 2 value of 0.7998 is in reasonable agreement with the adjusted R 2 value of 0.9062. In addition, numerical optimization results indicate that for 50 mL aqueous solution containing 11.39 mg/L of manganese, 1.0 g zinc chloride activated sawdust, pH of 5.0 and a contact time of 120 minutes will be required to obtain a sorption efficiency of 84.04% with amount removed (qe) of 714mg/g. The outcome of this study justifies the use of sawdust as adsorbent for the treatment of water and wastewater containing divalent metal ions.
