    Opis:
    The present work measures the adsorption capacity of sugarcane bagasse to remove excess lead from groundwater. Batch adsorption experiments were carried out to evaluate the adsorption equilibrium, and the effects of four parameters (pH, adsorbent dosage, equilibrium time and particle size) on the adsorption of lead were investigated. Characterization of the adsorbent was carried out through SEM and FTIR instruments. Results confirm that the adsorption of lead takes place successfully on the surface of the adsorbent. The maximum efficiency of adsorption is up to 50% achieved in 5g adsorbent dosage, at an optimum pH 5, with a contact time of 120 minutes and 53 μm adsorbent size at 38.

    Opis:
    Batteries are electric cells that use a reversible electrochemical process. One of the important components in the battery is the electrode. Electrodes in conventional batteries generally contain the B3 material. This study aimed to produce and characterize the bioelectrolytes made from blood clam shells and sugarcane bagasse. This study consisted of four stages, namely the stage of calcination of blood clam shells, the stage of hydrolysis of sugarcane bagasse, the stage of making bioelectrolyte paste, and the stage of test parameters. The test parameters performed included calcined blood clam shell morphology analysis using SEM, composition and mineral analysis on blood clam shell ash using XRF (X-Ray Fluorcence), analysis using UV-Vis spectrophotometry, and analysis using FTIR spectrophotometry. The characterization of the bioelectrolytes was tested using an AVOmeter or a multimeter connected using a connecting cable and an alligator clip. The best bioelectrolyte results were obtained using a reaction time of 90 minutes and a concentration of acid solution 30% (v/v) with a mixture of shell ash and sugarcane bagasse paste in 1:1 ratio. The best power produced was 0.02 watts.

    Opis:
    In this research, the upgrading of agro-industrial wastes was investigated by using the torrefaction pretreatment technique. Two types of biomass waste, including sugarcane bagasse (SBG) and palm kernel shell (PKS), were used as raw materials. The operating conditions, i.e., torrefaction temperature and residence time, are between 225–300 °C and 30–90 minutes. The findings show that, in terms of mass yield and calorific value of the solid product, the torrefaction temperature is a more sensitive parameter than the residence time. By increasing the torrefaction temperature from 225 to 300 °C, the mass yields are dropped in the range of 28.79–31.57 wt.% and 28.00–29.88 wt.%, while the effect of holding time exhibits the mass yield decreasing only 3.12–5.90 wt.% and 1.53–3.41 wt.%, for SBG and PKS torrefaction, respectively. In terms of calorific value, higher heating values increase as torrefaction severity increases, varying in the range of 0.29–2.84 MJ/kg, with torrefaction temperature as the dominant factor. Regarding the calorific value, energy yield, energy gain, and energy-mass co-benefit index, the optimal operating conditions for SBG and PKS torrefactions are the same condition as 275 °C for 90 minutes. SBG and PKS bio-coals obtained from torrefaction are promising solid fuels with high calorific value (about 23 MJ/kg), with an energy yield of 73.93–77.41%, relative to coal that could be further utilized for co-firing in thermal power plants.

    Sugarcane bagasse ash (SCBA)
    pozzolanic material and compressive strength
    Opis:
    The materials which are useless and unwanted is called waste product and this waste product is a burden and harmful to the environment. Sugarcane bagasse ash (SCBA) is one kind of waste which can be termed as the residue left over from burning sugar cane bagasse. The utilization of this waste may be very economical and can also solve the environmental problem. Silica and alumina are the main element of SCBA which is used as a pozzolanic material. This recycling procedure of SCBA reduces environmental pollution and this is also considered the cost-effective material. In this paper, SCBA replaces the cement as a weight of 5%, 10% and 15% which is considered. After completing the compressive strength test, the result shows that the compressive strength increases when 5% cement is replaced by sugarcane bagasse ash and this is the correct replacement of cement.

    Opis:
    Dilute sulfuric acid and acidic ionic liquids are pretreatment methods used to selectively hydrolyze hemicellulose from lignocellulosic biomasses. In this work, a comparison between these techniques is carried out by treating sugarcane bagasse both with 1-ethyl-3-methylimidazolium hydrogen sulfate at different ionic-liquid and water contents and with H 2 SO 4 at the same conditions and equivalent ionic liquid molar contents. Results from the use of ionic liquid showed that it was possible to tune the biomass treatment either to achieve high hemicellulose hydrolysis yields of 72.5 mol% to very low furan and glucose co-production, or to obtain furfural at moderate yields of 18.7 mol% under conditions of low water concentration. In comparison to the use of ionic liquid, sulfuric acid pretreatment increased hemicellulose hydrolysis yields by 17%, but the 8.6 mol% furfural yield was also higher, and these yields were obtained at high water concentration conditions. Besides, no such tuning ability of the biomass treatment conditions can be made.
