Efficient co-production of xylooligosaccharides, furfural and reducing sugars from yellow bamboo via the pretreatment with biochar-based catalyst

The research on the efficient use of biomass to produce chemical products has received extensive attention. In this work, a novel heterogeneous biocarbon-based heterogeneous catalyst AT-Sn-YB was prepared using yellow bamboo (YB) as a carrier, and its physical properties were proved to be good by various characterization and stability experiments. In the γ-valerolactone/water (3:1, v/v) medium containing 100 mM CuCl2, the use of AT-Sn-YB (3.6 wt%) under 170 °C for 20 min was applied to catalyze YB into furfural (80.3% yield), accompanied with 2.8 g/L xylooligosaccharides. The YB solid residue obtained from treatment was efficiently saccharified to reducing sugars (17.2 g/L). Accordingly, comprehensive understanding of efficiently co-producing xylooligosaccharides, furfural and reducing sugars from YB was demonstrated via the pretreatment with biochar-based catalyst. This study innovatively used a new type of solid acid to complete the efficient co-production of chemical products, and realized the value-added utilization of yellow bamboo.

Characterization of Indonesian Bamboo Charcoal for Enhanced Adsorption Capabilities

Bamboo charcoal from four types of Indonesian bamboo species had been successfully prepared and characterized. The yield was 19.67%; 30.86%; 33,16% and 27,34 respectively for Apus bamboo, Javanese bamboo, Ori bamboo and Yellow bamboo. The activation of bamboo charcoal was carried out chemically using KOH and H3PO4. Activated bamboo charcoal was characterized for the content of water, volatile substance, total ash, and carbon, as well as iodine absorption capacity based on the technical standard of activated carbon SNI 06-3730-1995. The activated bamboo charcoal was also characterized using Fourier Transform Infrared (FTIR) to determine the functional groups, SEM to determine morphology and nitrogen adsorption desorption to determine the surface area. The activation process was able to reduce water, ash, volatile substance content; thereby increasing carbon content which has the potential to be used for adsorption, and this is evidenced by the increase in the value of iodine absorption. From the FTIR data activated bamboo charcoal shows the presence of a C=O at 1500-1600 cm-1, O-H at 3400-3500 cm-1 and CO at 1300-1400 cm-1 which has the potential to contribute the active site for adsorptionprocess. Based on SEM data the morphology of activated bamboo charcoal was porous. Enhance quantity of pores would increase the surface area and the adsorption ability. From the results of the surface area data, it was found that the 4 types of activated bamboo charcoal produced a higher surface area, and activation using KOH was more effective than H3PO4in increasing the surface area of activated bamboo charcoal.

Nutrient recovery from biogas slurry via hydrothermal carbonization with different agricultural and forestry residue

Hydrothermal carbonization (HTC) of various agricultural and forestry waste (yellow bamboo, green bamboo, peanut shell, wood meal, peanut straw, wheat straw, rice husk, corn straw) with biogas slurry (BS) was studied, with the goal of recovering nutrients from BS. The ideal biomass material for nitrogen recovery was green bamboo, where 46.64 % of N was recovered after HTC at 250 °C for 3 h. The best one for phosphorus recovery was peanut straw, where P in liquid residue was not detectable post HTC. However, with all types of biomass tested, HTC failed recovering potassium from BS. Nitrogen recovery performance was positively correlated to the total cellulosic content of biomass as C-N active binding site for the formation of aliphatic amine were mainly provided by cellulose and hemicellulose. Increased metal salt concentration in biomass feedstock promoted phosphorus recovery as the mechanism was formation of metal phosphate precipitates. The hydrochars obtained from different biomass samples resulted in a wide range of pore sizes, which was critical for nutrient slow-release characteristics and plant growth promoting microorganism immobilization. Pot experiment further confirmed corn straw hydrochar had significant advantages over chemical fertilizer in water and nutrient retaining, which was critical for the enhancement of long-term soil fertility.

Culm Characteristics of Yellow Bamboo (Bambusa vulgaris var. striata) from Private Forest in Sleman Regency, Yogyakarta

Sleman Regency has determined bamboo as a superior non-timber forest product. Yellow bamboo (Bambusa vulgaris var. striata) is usually used for construction and craft materials. Hence, it is necessary to understand the characteristics of the culm. The study aimed to determine the predictor variables for the total internodes, and the distribution pattern of the length and bamboo wall thickness of the internodes on the yellow bamboo culms. The method used in this research was the method of destructive sampling for 30 bamboo culm samples. The samples were measured using a caliper for diameter at breast height and wall thickness, and measurement tape for the total length of the bamboo culm. For detail measurement, each sample was cut for each internode to be measured the length, diameter, and wall thickness of the internodes. The results showed that the predictor of diameter at breast height (dbh) is a predictor in estimating the total number of internodes on the culm resulting in an R2 of 0.631. While the total culm height as a predictor was able to explain the total number of internodes with an R2 value of 0.692. The length of the internodes pattern on the yellow bamboo culm from the bottom to the top side formed a bell curve. In the middle area of the culm, the length of the internode increased, but then it shrank back to the top side. The diameter and wall thickness patterns of the internode were non-linear. In addition, the predictors of diameter at breast height and total height are less accurate to explain the total number of internodes in yellow bamboo culms.
