Guadua angustifolia biochar/TiO2 composite and biochar as bio-based materials with environmental and agricultural application

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 2, 2025

Globally, the companies that make commercial use of bamboo culms produce different kinds solid waste rich in lignocellulosic biomass, which some cases is not used and discarded landfills or incinerated open air; losing possibility recovering them using other productive sectors. The research objective were to a biochar from Guadua agustifolia Kunth sawdust, evaluate its potential environmental agricultural use, obtain biochar/TiO2 composite inactivate Escherichia coli as soil conditioner medicinal plants producing phenolic compounds flavonoids. Biochar (produced at 300 °C for 1 h) involved TiO2 450 h inactivation E. (initial concentration: 6.5 ± 0.3 Log10 CFU mL− 1). For agriculture, 2% was B. pilosa L. G. angustifolia plant growth 90 days. had high photocatalytic activity on coli, generating final count 1.97 0.2 after 60 min. (2%) increased total phenol flavonoid content phenols angustifolia, tested nursery stage. This study provides new information conversion sawdust an alternative bio-based materials with applications. In addition, obtaining could positively impact production chain Colombia because renewable globally accepted alternatives help capture gaseous emissions causing greenhouse effect.

Influence of Pyrolysis Temperature and Time on Biochar Properties and Its Potential for Climate Change Mitigation

Journal of Human Earth and Future, Journal Year: 2023, Volume and Issue: 4(4), P. 472 - 485

Published: Dec. 1, 2023

The thermochemical conversion of disposable bamboo chopstick (DBC) wastes into biochar is a practical strategy for converting waste resources. This study aimed to investigate the effects pyrolysis temperature and holding time on physicochemical properties DBC its potential climate change mitigation. Properties affecting efficiency application were analyzed: moisture content (MC), volatile matter (VM), fixed carbon (FC), ash, pH, (C), hydrogen (H), nitrogen (N), oxygen (O) content. Six different conditions studied, with temperatures 400 °C, 450 500 °C times 20 60 min, at constant heating rate. results demonstrated that significantly affected performance biochar. Increases in %C, %FC, %N, pH reductions %MC, %VM, %H, %O found when was increased times. aromaticity polarity decreased increasing time. showed interacts time, these two factors jointly affect contents MC, FC, C, H, N, O (R2 0.997) (R2of 0.999). obtained via min could be applied best min. good hydrophobicity, tremendous stability, highest C (88.06%) FC (76.49%) values, lowest ash (2.62%) VM (19.23%) contents.

Taking Advantage of Disposal Bamboo Chopsticks to Produce Biochar for Greenhouse Crop Cultivation

Emerging Science Journal, Journal Year: 2024, Volume and Issue: 8(3), P. 917 - 932

Published: June 1, 2024

Biochar is a value-added product that can be used for many purposes, particularly environmental and agricultural purposes. In this study, pyrolysis at 450–500 °C was to upgrade urban waste such as disposable bamboo chopsticks (DBCs) into biochar. The properties of DBC biochar were analyzed, the subsequently cultivate Romaine lettuce assess its potential soil amendment. Its properties, including specific surface area (SSA), pore size, volume, pH, cation exchange capacity (CEC), contents carbon (C), hydrogen (H), nitrogen (N), oxygen (O), macronutrient content, atomic ratio H/C, O/C, (O+N)/C, C/N, analyzed. experimental pots consisted four treatments, each with ten replicates: unamended (TC), amended 10% (w/w) vermicompost (TV), mixed 1.5% (TVB1.5), 2.5% (TVB2.5). Fundamental physicochemical plant yield (plant height, leaf width, number leaves, fresh weight) investigated. results indicated neutral (pH 6.80) had high CEC (10.86 cmol/kg), 66.80% C, 3.76% H, 25.93% O, 0.61% N. It mesopores (39.077 Å), large SSA (0.542 m2/g), volume 0.005 cc/g. exhibited aromaticity hydrophobicity. Based on these results, has amendment: it significantly enhances quality increases yields. application resulted in highest yield. Doi: 10.28991/ESJ-2024-08-03-07 Full Text: PDF
