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

Enhancing CO2 Sequestration Through Corn Stalk Biochar-Enhanced Mortar: A Synergistic Approach with Algal Growth for Carbon Capture Applications

Sustainability, Journal Year: 2025, Volume and Issue: 17(1), P. 342 - 342

Published: Jan. 5, 2025

This study examines corn stalk biochar (CSB)-enhanced mortar as an innovative material for carbon capture and CO2 sequestration. CSB, a renewable agricultural byproduct, was incorporated into cement at varying concentrations (2.5% to 75%), its effects on the mortar’s physicochemical properties, ability support algal growth, absorption capacity of algae were analyzed. Characterization CSB showed high content (62.3%), significant porosity, large surface area (680.3 m2 g−1), making it ideal gas capture. At low (2.5%), slightly improved compressive strength density. However, higher levels (5% 75%) led reductions (p < 0.05) in density, while water increased. sequestration monitored from growth studies revealed that both Chlorella sp. (TISTR 8262) Scenedesmus 9384) thrived CSB-enhanced mortars. 75% concentration, achieved 24.2-fold increase biomass by day 12, outperforming sp., which 26.6-fold increase. also with biochar. Mortars 86% ratio without algae, adding boosted this nearly 100%, highlighting synergistic effect photosynthesis. Higher accelerated stabilization, reaching saturation 8 CSB. efficiency than peak earlier maintaining greater efficiency. absorption, indicating biochar–mortar mixtures, particularly when combined provide promising solution enhancing green infrastructure.
