Pelletization and briquettization have been extensively used for mass and energy densification of biomass. As the demand for pellets increases, the biorefinery waste lignin can be used with the conventional raw materials for pellet preparation. Sugarcane bagasse (20-40 mesh) is treated with NaOH (8% & 16%) for bioethanol production and obtained lignin is used to prepare pellet along and with sugarcane bagasse (SB). SB, Lignin1 (8% NaOH treated SB), Lignin2 (16% NaOH treated SB) and various composition of SB and Lignin1 were used to produce pelletswith different applied pressures (5kN, 10kN, 15kN and 20kN). Pellet density and heating value were gradually increase with the applied pelletization pressure. Among the samples Lignin1 showed highest heating value at 20kN (3581.54 kcal/kg). Results revealed that 5kN is enough to produce pellet from different composition of SB and Lignin1 and the pellet composition of SB (40%) and Lignin1(60%) showed the highest heating value (3456.21 kcal/kg).

Biomass Residues

A study of the pyrolysis and gasification of biomass residues such as oil palm shells and fibers, coffee shells, sugarcane bagasse and beech wood is presented. All of them are abundant agroindustrial biomass residues in Latin American countries. The characterization of the raw materials and products includes proximate analysis (water, ash and volatile matter contents) and ultimate analysis. Pyrolysis and gasification experiments are carried out in a thermobalance and in a pilot scale rotary kiln reactor. Both facilities are equipped with evolved gas analysis. Pyrolysis experiments were carried out using nitrogen as carrier gas by heating up to a temperature of 950 °C. Gasification is performed using water vapour as reaction agent in a concentration of 70 % H2O in nitrogen. The gasification temperature is set to 850 °C. All wastes show similar behavior during pyrolysis in the thermobalance with the main mass loss at temperatures below 550 °C. The solid fraction varied from 18 % for sugarcane bagasse to 27 % for oil palm shells and the gas fraction from 18 % for oil palm shells to 22 % for sugarcane bagasse. The main evolved gases are CO2 (9 – 12%), CO (3.5 – 7.5 %) and CH4 (1.6 – 3 %). H2 was also found but in a very small fraction (0.5 – 0.7 %) (all fractions are referred to the initial dry mass). The heating value of the pyrolysis products from the experiments in the thermobalance of the different wastes presented small variations with a mean value of 6.5 MJ kg-1 for the evolved gas, 20 MJ kg-1 for the tar and 19 MJ kg-1 for the solid residual. The presence of secondary reactions in the rotary kiln affects considerably the amount of gas and tar in the products. The higher heating value of the evolved gases varies between 17 and19 MJ kg-1. The obtained results allow a possible further technological use of these materials as a cheap renewable energy source in countries where these materials can be found.

Biological Sludge

Man-made organic waste leads to the rapid proliferation of pollution around the globe. Effective bio-waste management can help to reduce the adverse effects of organic waste while contributing to the circular economy at the same time. The toxic oily-biological sludge generated from oil refineries’ wastewater treatment plants is a potential source for biogas energy recovery via anaerobic digestion. However, the oily-biological sludge’s carbon/nitrogen (C/N) ratio is lower than the ideal 20–30 ratio required by anaerobic digestion technology for biogas production. Sugarcane bagasse can be digested as a high C/N co-substrate while the oily-biological sludge acts as a substrate and inoculum to improve biogas production. In this study, the best C/N with co-substrate volatile solids (VS)/inoculum VS ratios for the co-digestion process of mixtures were determined empirically through batch experiments at temperatures of 35–37 °C, pH (6–8) and 60 rpm mixing. The raw materials were pre-treated mechanically and thermo-chemically to further enhance the digestibility. The best condition for the sugarcane bagasse delignification process was 1% (w/v) sodium hydroxide, 1:10 solid-liquid ratio, at 100 °C, and 150 rpm for 1 h. The results from a 33-day batch anaerobic digestion experiment indicate that the production of biogas and methane yield were concurrent with the increasing C/N and co-substrate VS/inoculum VS ratios. The total biogas yields from C/N 20.0 with co-substrate VS/inoculum VS 0.06 and C/N 30.0 with co-substrate VS/inoculum VS 0.18 ratios were 2777.0 and 9268.0 mL, respectively, including a methane yield of 980.0 and 3009.3 mL, respectively. The biogas and methane yield from C/N 30.0 were higher than the biogas and methane yields from C/N 20.0 by 70.04 and 67.44%, respectively. The highest biogas and methane yields corresponded with the highest C/N with co-substrate VS/inoculum VS ratios (30.0 and 0.18), being 200.6 mL/g VSremoved and 65.1 mL CH4/g VSremoved, respectively.

This study evaluated the potential use of Sugarcane Bagasse Ashes (SBA) as a flux, replacing phyllite for the production of enamelled porcelain tile. The raw materials of the standard mass components and the SBA residue were characterized by testing by XRF, XRD, AG, DTA and TGA. Test samples were fabricated, assembled in lots of 3 units and sintered at temperatures of 1150 ° C to 1210 ° C. The results of the physical properties, mechanical properties and SEM of the sintered samples, showed that the formulation, G4 - in which applied 10% of SBA replacing phyllite, sintering temperature 1210 ° C showed better performance as the previously mentioned properties due to the formation of mullite crystals, meeting the prerequisites of standards for enamelled porcelain tile, while reducing the environmental impact and the cost of production.
