Published: Jan. 16, 2023

Abstract Carbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, traditional soil amendment which has been used for fertility improvement and contaminant remediation, revealed new vitality in this context. In review we highlight huge potential of biochar application different fields to mitigate as high 2.56 × 10 9 t CO 2 e total greenhouse gas (GHG) emissions per year, accounting 5.0% global GHG emissions. Soil applications either controlled-release fertilizer or an immobilization agent offer improved health while simultaneously suppressing CH 4 N O. Non-soil also contribute carbon unique ways. Firstly, ruminant feed decreases via physical sorption enhanced activities methanotrophs. Secondly, can be green catalyst biorefinery. Besides, additive Portland cement low impact development (LID) infrastructure lowers footprint builds resilience climate change. Furthermore, novel batteries supercapacitors energy storage purposes. Finally, adsorption capacity makes it possible being sorbent capture, utilization, (CCUS). We advocate that future research should further explore effectiveness systems change mitigation large scale applications, assess economic social viability local combat Graphical

Atmospheric carbon removal via industrial biochar systems: A techno-economic-environmental study

Journal of Cleaner Production, Journal Year: 2022, Volume and Issue: 371, P. 133660 - 133660

Published: Aug. 20, 2022

It is critical to develop carbon removal projects that are both effective and financially viable. Herein, we investigated the potential of an industrial biochar system in Spain. This study first assess techno-economic-environmental impact large-scale olive tree pruning residue pyrolysis for atmospheric removal, using integrated assessment framework based on current market dynamics. Production optimization response surface methodology (RSM) was carried out, aiming maximize yield, production throughput stable content while prioritizing stability. determined optimized attained at 650 °C 15 min residence time. Furthermore, a plant with biomass processing capacity 6.5 tonnes-per-hour designed further analysis. A thermodynamic model developed Advanced System Process Engineering (ASPEN Plus) software, process be self-sufficient availability surplus energy. Moreover, life cycle (cradle-to-grave) revealed approximately 2.68 tCO2e permanently removed from atmosphere per tonne produced, after accounting footprint entire process. corresponds 3.26 hour 24,450 annually. The economic project profitable; however, profitability sensitive pricing service biochar. internal rate return (IRR) 22.35% achieved price combination EUR 110/tonne CO2e 350/tonne biochar, feedstock cost 45 EUR/tonne (delivered 20% moisture content), where product within lower bound pricing. If exclusively offer service, minimum 206/tonne required achieve profitability, same cost. findings this demonstrate viability immediately deploying biochar-based via pyrolytic conversion residues address climate crisis.

Biochar Production, Modification, and Its Uses in Soil Remediation: A Review

Sustainability, Journal Year: 2023, Volume and Issue: 15(4), P. 3442 - 3442

Published: Feb. 13, 2023

Soil remediation is the act of removing or reducing availability contaminants from soil. In case agriculture, soil targets removal pollutants, including residual pesticides/herbicides, hydrocarbons, and toxic heavy metals. This often done by chemical treatments with multiple washes excavation soils, which are costly time-consuming. Therefore, finding cheaper, less time-consuming methods highly desirable. this review, we will examine addition biochar as an effective method remediation. Biochar a carbon-rich material derived burning biomass in oxygen-limited environment benefits such high cation exchange capacity, large surface area, neutral to alkaline pH, some nutritional content. can also be sanctuary for naturally occurring microbes inoculated specific contaminant breakdown. The physical characteristics combined biological activity help bind promote degradation process these without need use hazardous chemicals remove amount Biochar, they house, through electrostatic attraction, sorption, precipitation, bioaccumulation, their surrounding environment. However, its vary depending on feedstock, pyrolysis temperature, time mass heated. traits modified pre post-treatments suit intended use, allowing made contaminants. review hopes increase interest research fill missing gaps information that could make production cheaper more consistent, it offers greener way clean up

The global impact of water and soil contamination has become a serious issue that affects the world all living beings. In this sense, multiple treatment alternatives have been developed at different scales to improve quality. Among them, biochar suitable alternative for environmental remediation due its high efficiency low cost, raw material used production comes from residual biomass. A is carbonaceous with interesting physicochemical properties (e.g., surface area, porosity, functional groups), which can be prepared by synthesis methods using agricultural wastes (branches banana rachis, cocoa shells, cane bagasse, among others) as feedstock. This state-of-the-art review based on general description remediation. Biochar’s production, synthesis, uses also analyzed. addition, work shows some thus several applications, like removing heavy metals, oil, dyes, other toxic pollutants. Physical chemical modifications, precursors, dopants, promoting agents Fe N species) discussed. Finally, primary corresponding mechanism quality (via adsorption, heterogeneous photocatalysis, advanced oxidation processes) described, both laboratory medium large scales.
