Abstract

Biochar is a porous carbonaceous material produced from the pyrolysis of biomass under limited oxygen conditions, and it has gained widespread attention for its effectiveness in environmental remediation, soil quality enhancement, and carbon sequestration. The physicochemical properties of biochar are highly dependent on the type of biomass feedstock and the production parameters applied. Utilizing biomass waste as a raw material for biochar not only addresses organic waste management issues but also produces value-added products suitable for various applications, such as pollutant adsorption, soil amendment, and alternative fuel sources. This review aims to systematically evaluate the potential of various biomass types as biochar feedstock, focusing on the influence of feedstock composition, pyrolysis conditions, and resulting biochar characteristics on its application performance. The study integrates recent findings in the literature, demonstrating that appropriate selection of biomass—such as oil palm empty fruit bunches, sugarcane bagasse, cotton shells, lignin, and red mud—can yield high-performance biochar for heavy metal remediation, synthetic dye adsorption, and renewable energy production. This review is expected to provide a scientific foundation for developing more efficient, adaptive, and sustainable biomass-based biochar production strategies.

Abstract

This study aims to evaluate the dynamic performance of NaOH-activated hybrid adsorbent derived from jengkol peels and coconut shell for Cu(II) removal in a fixed-bed column. The performance indicators include the adsorption capacity, removal efficiency, and structural characterization. The hybrid adsorbent was characterized using Fourier Transform Infrared Spectroscopy (FTIR) to identify functional groups that play a role in the adsorption process and Scanning Electron Microscope (SEM). The FTIR characterization results showed that the hybrid adsorbent was rich in functional groups such as hydroxyl (-OH), aromatic stretching (C=C), and aliphatic (C-H) groups. Meanwhile, the SEM characterization showed that the surface structure of the adsorbent tended to be honeycomb-shaped with varying pores. The adsorption test was performed in a downflow fixed-bed column under continuous operation with a total operation time of 30 minutes. Under the tested conditions (influent concentration of 100 mg/L and flow rate of 25 mL/min), 95% removal was achieved at 30 min in the fixed-bed column system, corresponding to a dynamic adsorption capacity of 11.3 mg/g. Kinetic modelling indicated that the Thomas and Yoon – Nelson models provided a better fit than the Adam-Bohart model, indicating that adsorption was primarily controlled by surface kinetics rather than intraparticle diffusion. This biomass waste-based hybrid adsorbent has the potential to be an environmentally friendly alternative for treating liquid waste containing Cu ions.
