Obtaining biochar from rice husk and straw

Novosti nauki Kazahstana, 2023
This paper presents the results of research on obtaining biochar from agricultural plant waste such as rice husk and straw. The selection of the optimal conditions for thermolysis, such as the duration and temperature of the process, has been conducted.

Remediation of uranium-contaminated acidic red soil by rice husk biochar

Environmental Science and Pollution Research, 2022
Uranium (U) in the U-contaminated acidic red soil exhibits high mobility. In the present study, rice husk was used to produce biochar to remediate U-contaminated red soil under acid precipitation. Firstly, batch adsorption experiments showed that the dissolution of alkaline substance in biochar could buffer the pH value of acidic solution.

Biomass Carbonization - Production and Characterization of Biochar from Rice Husks

2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019
The present work had the objective to produce and characterize charcoal from rice husks. The rice husk was generated in a Top-lit updraft reactor. This process was favorable for biochar production. By increasing the airflow from 12 to 24 L/min, the reaction temperature increased from 714 to 935 ° C (R2 = 0.90), respectively.

Enrichment of antioxidant peptide from rice protein hydrolysates via rice husk derived biochar

Food Chemistry
In this study, rice husk biochar was engineered with abundant iron ion sites to enhance the enrichment of antioxidant peptides from rice protein hydrolysates through metal-chelating interactions. The π-π interactions and metal ion chelation were identified as the primary mechanisms for the enrichment process.

Comparative study of rice husk biochars for aqueous antibiotics removal

Journal of Chemical Technology & Biotechnology, 2017
AbstractBACKGROUNDAntibiotics are widely used for the treatment of bacterial infections in humans and animals, but it can be released into water sources due to incomplete metabolism in humans or via discharge from drug manufacturers.RESULTSThe efficiency of removal of three antibiotics was enhanced with increasing biochar dosage.

In Vivo Genotoxicity of Rice Husk Biochar on Eudrilus eugeniae in Soil

Bulletin of Environmental Contamination and Toxicology, 2020
Biochar (char-product), generated by pyrolyzing organic materials, is produced for the intended use of land application to promote carbon sequestration, soil improvement and crop-yield. Despite the benefits biochar applications offers, scientific probing on impacts that may result from amendments with biochar is still fragmented.

Characterization, Activation, and Life Cycle Analysis of Rice Husk Biochar

Journal of Agricultural Engineering (India)
Rice husk is generated in abundance in India, and requires efficient utilization for sustainable management of agricultural residues. Traditionally, farmers burn rice husks, which leads to environmental degradation. Biochar production offers an effective waste management solution, mitigating climate change concerns.

In situ preparation of biochar coated silica material from rice husk

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2012
Abstract An alternative approach to the utilization of lignocellulosic biomass is reported in this paper. It was the first time that rice husk was used as carbon source to synthesize carbon coated silica particles. Rice husk was hydrolyzed and mixed with silica powder, then biochar coated silica particles were simply in situ synthesized.

Adsorption and electro‐catalytic performance of biochar from rice husk

Journal of Chemical Technology & Biotechnology
AbstractBACKGROUNDOrganic pollutants, such as rhodamine B (RhB), methylene blue (MB), and 1,2‐dihydroxybenzene (catechol) used in dyes, textile industries, cosmetics, plasticizers, pesticides, and pharmaceuticals are difficult to be degraded and have important influence on the ecosystems and human beings.
