Abstract Sugarcane bagasse waste biomass (SBWB) efficacy for the adsorption of Zr(IV) was investigated in batch and column modes. The process variables i.e. pH 1–4 (A), adsorbent dosage 0.0–0.3 g (B), and Zr(IV) ions initial concentration 25–200 mg/L (C) were studied. The experiments were run under central composite design (CCD) and data was analysed by response surface methodology (RSM) methodology. The factor A, B, C, AB interaction and square factor A2, C2 affected the Zr(IV) ions adsorption onto SBWB. The quadratic model fitted well to the adsorption data with high R2 values. The effect of bed height, flow rate and Zr(IV) ions initial concentration was also studied for column mode adsorption and efficiency was evaluated by breakthrough curves as well as Bed Depth Service and Thomas models. Bed height and Zr(IV) ions initial concentration enhanced the adsorption of capacity of Zr(IV) ions, whereas flow rate reduced the column efficiency.

Abstract In this work, sugarcane bagasse waste (SBW) was used as a lignocellulosic precursor to develop a high surface area activated carbon (AC) by thermal treatment of the SBW impregnated with KOH. This sugarcane bagasse waste activated carbon (SBWAC) was characterized by means of crystallinity, porosity, surface morphology and functional groups availability. The SBWAC exhibited Type I isotherm which corresponds to microporosity with high specific surface area of 709.3 m2/g and 6.6 nm of mean pore diameter. Further application of SBWAC as an adsorbent for methylene blue (MB) dye removal demonstrated that the adsorption process closely followed the pseudo-second order kinetic and Freundlich isotherm models. On the other hand, thermodynamic study revealed the endothermic nature and spontaneity of MB dye adsorption on SBWAC with high acquired adsorption capacity (136.5 mg/g). The MB dye adsorption onto SBWAC possibly involved electrostatic interaction, H-bonding and π-π interaction. This work demonstrates SBW as a potential lignocellulosic precursor to produce high surface area AC that can potentially remove more cationic dyes from the aqueous environment.

Eco-friendly hydrophobic coatings were fabricated on tiles via the drop-casting process. Sugarcane bagasse waste ash (SBA) was used as a silica source and dimethyldiethoxysilane (DMDEOS) was used as a surface functionalizing agent. The elemental composition of SBA was measured using X-ray fluorescence (XRF) and energy-dispersive spectroscopy (EDS) techniques. The surface morphology of SBA was analyzed through the field-emission scanning electron microscopy (FESEM) technique. The surface wettability of SBA coated tiles was evaluated by determining the static water contact angle (WCA). XRF studies showed that the impurities were removed, and the silica content was enriched by the acid treatment. SBA coated tiles showed good hydrophobicity with a WCA of 135°. The high hydrophobicity of the coated tiles may be attributed to the increase of surface roughness by SBA. Moreover, the SBA coating was successfully tested on various substrates such as tiles, brick, glass, and cotton cloth. SBA coated glass substrate was more durable compared to other substrates at normal room temperature.

In this paper, it was consider the study of the use of sugarcane bagasse and wood particles, residues from the agricultural and the furniture industry, in order to add value to such materials. To add value to these materials it will be utilized in the manufacturing of hybrid panels consisting of wood particles and sugarcane bagasse in certain proportions (20%, 40% and 60%). For the production it was used the bi-component polyurethane resin based on castor oil. Analysis of the products was established based on the physical-mechanical standard NBR 14.810:2006. The hybrid panels were analyzed according to the data obtained in relation to the American standard ANSI A208.1-1999, in order to determine the best treatment for the possible use as a lining in agricultural buildings. Moreover, the hybrid panels were contrasted with panels of other formulations, with similar density. It was evident that the treatment constituting of 40% of sugar cane bagasse and 60% of wood particles had the best physical-mechanical, and showed a potential for the use in non-structural applications.

This research aimed to study the preparation of activated carbon from sugarcane bagasse waste. The sugarcane bagasse adsorbent was prepared by calcination at 600°C for 2 hours with the use of sulfuric acid (H2SO4) as a chemical activation. The adsorption surface possessed high specific surface area (838 m2/g) with mesoporous diameter. Factors explaining adsorption including adsorption isotherm, adsorption kinetic and adsorption mechanism were constructed from methylene blue adsorption experiments. It was found that the equilibrium data was best represented by Freundlich isotherm, showing multilayer coverage of dye molecules at the outer surface of adsorbent with a cooperative adsorption (physisorption and chemisorption). The kinetic of methylene blue adsorption was found to follow pseudo-second-order rate kinetic model, with a good correlation coefficient. This indicated that the overall rate of the dye adsorption process was controlled by the chemisorption process.

Bagasse Waste

Sugarcane bagasse is one of the solid waste that can be processed as a mixture of structure materials. In theprevious research, sugarcane bagasse has been processed and used as a mixture of portland cement, the manufacture ofasbestos and also mixtures for manufacturing of brake pads that are frequently used in motor vehicle. Based on theprevious research results, it is strongly necessary to develop a research about sugarcane bagasse for structure materials.The method used to determine the mechanical properties is tensile test and compression test. To obtain the intensity ofmaterial variations, it is needed to make various sizes of filtration carbon in the form of aggregate that is mixed into thetiles material. The size of the aggregate used in concrete material can be on 200 μm, 400 μm and 600 μm. This measure istaken in accordance with the size of the filtration apparatus. Furthermore, in obtaining sugarcane bagasse carbon, theresearcher must do the oven curing process on 200 0C temperature and 3 hours in curing oven. In this research the bestresult is used bagasse powder mixtured 200 μm is 7. 2 MPa.
