Biochar for agronomy, animal farming, anaerobic digestion, composting, water treatment, soil remediation, construction, energy storage, and carbon sequestration: a review

Environmental Chemistry Letters, Journal Year: 2022, Volume and Issue: 20(4), P. 2385 - 2485

Published: May 7, 2022

Abstract In the context of climate change and circular economy, biochar has recently found many applications in various sectors as a versatile recycled material. Here, we review application biochar-based for carbon sink, covering agronomy, animal farming, anaerobic digestion, composting, environmental remediation, construction, energy storage. The ultimate storage reservoirs are soils, civil infrastructure, landfills. Biochar-based fertilisers, which combine traditional fertilisers with nutrient carrier, promising agronomy. use feed additive animals shows benefits terms growth, gut microbiota, reduced enteric methane production, egg yield, endo-toxicant mitigation. Biochar enhances digestion operations, primarily biogas generation upgrading, performance sustainability, mitigation inhibitory impurities. composts, controls release greenhouse gases microbial activity. Co-composted improves soil properties crop productivity. Pristine engineered can also be employed water remediation to remove pollutants. added cement or asphalt, thus conferring structural functional advantages. Incorporating biocomposites insulation, electromagnetic radiation protection moisture control. Finally, synthesising materials requires additional functionalisation.

Performance and Mechanism of Fe₃O₄ Improving Biotransformation of Waste Activated Sludge into Liquid High-Value Products

Environmental Science & Technology, Journal Year: 2022, Volume and Issue: 56(6), P. 3658 - 3668

Published: March 7, 2022

This study demonstrated that Fe3O4 simultaneously improves the total production and formation rate of medium-chain fatty acids (MCFAs) long-chain alcohols (LCAs) from waste activated sludge (WAS) in anaerobic fermentation. Results revealed when increased 0 to 5 g/L, maximal MCFA LCA significantly, optimal fermentation time was also remarkably shortened 24 9 days. Moreover, enhanced WAS degradation, corresponding degradation system 43.86 72.38% with an increase g/L. Further analysis showed promoted microbe activities all bioprocesses (including hydrolysis, acidogenesis, chain elongation processes) involved WAS. Microbial community indicated abundances key microbes abovementioned correspondingly. Mechanistic investigations conductivity fermented sludge, providing a better conductive environment for microbes. The redox cycle Fe(II) Fe(III) existed Fe3O4, which likely act as electron shuttles conduct transfer (ET) donor acceptor, thus increasing ET efficiency. provides effective method enhancing biotransformation into high-value products, potentially bringing economic benefits treatment.

Important soil microbiota's effects on plants and soils: a comprehensive 30-year systematic literature review

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: March 25, 2024

Clarifying the relationship between soil microorganisms and plant-soil system is crucial for encouraging sustainable development of ecosystems, as serve a variety functional roles in system. In this work, influence mechanisms significant microbial groups on their applications environmental remediation over previous 30 years were reviewed using systematic literature review (SLR) methodology. The findings demonstrated that: (1) There has been general upward trend number publications microorganisms, including bacteria, fungi, archaea. (2) Bacteria fungi plant growth through organic matter decomposition, nitrogen, phosphorus, potassium element dissolution, symbiotic relationships, hormone production, pathogen inhibition, resistance induction. Archaea aid plants by breaking down low-molecular-weight matter, participating cycles, producing hormones, suppressing infections. (3) Microorganism principles are utilized remediation, biofertilizer denitrification, phosphorus removal, effectively reducing pollution, preventing invasion, protecting vegetation health, promoting growth. three important collectively regulate ecosystem help maintain its relative stability. This work systematically summarizes systems, providing theoretical reference how to control microbes order restore damaged ecosystems enhance resilience future.
