Biochar (BC), also referred to as “black gold”, is a carbon heterogeneous material rich in aromatic systems and minerals, preparable by the thermal decomposition of vegetable animal biomasses controlled conditions with clean technology. Due its adsorption ability presence persistent free radicals (PFRs), BC has demonstrated, among other uses, great potential removal environmental organic inorganic xenobiotics. Bamboo an evergreen perennial flowering plant characterized short five-year growth period, fast harvesting, large production many tropical subtropical countries worldwide, thus representing attractive, low-cost, eco-friendly, renewable bioresource for producing BC. their surface area increased porosity, pyrolyzed derivatives bamboo, including bamboo biochar (BBC) or activated BBC (ABBC), are considered bio-adsorbent materials removing heavy metals, well contaminants from wastewater soil, improving yield. Nowadays, increasing technological applications ABBC include employment energy sources, catalyze chemical reactions, develop thermoelectrical devices, 3D solar vapor-generation devices water desalination, efficient photothermal-conversion devices. Anyway, although it alternative biomass wood produce BC, paving way new bio- circular economy solutions, study bamboo-derived still infancy. In this context, main scope review was support stimulate further studies about possible applications, enlarging current knowledge these allowing more rational, safer, optimized application. To end, after having provided background concerning methods, we have reviewed discussed on reported recent years.

Abstract Large amount of wastes are burnt or left to decompose on site at landfills where they cause air pollution and nutrient leaching groundwater. Waste management strategies that return these food agricultural soils recover the carbon nutrients would otherwise have been lost, enrich improve crop productivity. The incorporation liming materials can neutralize protons released, hence reducing soil acidity its adverse impacts environment, security, human health. Biochar derived from organic residues is becoming a source input provides multifunctional values. be alkaline in nature, with level alkalinity dependent upon feedstock processing conditions. This study conducted characterization biochar pyrolysis process eggplant Acacia nilotica bark temperatures 300 °C 600 °C. An analysis was kinds determine their pH, phosphorus (P), as well other elemental composition. proximate by ASTM standard 1762-84, while surface morphological features were measured using scanning electron microscope. exhibited greater yield higher fixed possessing lower content ash volatile components compared eggplant. exhibits ability acacia bark-derived biochar. calcium carbonate equivalent, potassium (K), (P) levels biochars increased temperature increased. results suggest could beneficial resource for storing soil, addressing enhancing availability, particularly acidic soils.

Abstract Water remediation with biomass derivatives has attracted attention for its sustainable impact on the earth. Chemical procedures new adsorbent and active biomaterials must be implemented to remove organic pollutants more efficiently. Herein, we obtained a sustainable, environmentally, low‐cost biochar from bamboo Dendrocalamus giganteus (BBC, B400) by thermal treatment at 400 °C without physical chemical pre‐ post‐treatments. By electron paramagnetic resonance (EPR), determined quantification ageing of persistent free radicals (PFRs, 10 16 –10 19 spins/g) present in BBC over time. We demonstrated removal efficiency (R %) B400 against methylene blue (MB) aqueous solutions different concentrations H 2 O using novel B400‐packed column‐flow system. Results that MB via adsorption degradation strongly depended concentration carbon‐centred PFRs their stability Collectively, reduced full passivation proper treatments led remarkable loss efficiency, thus evidencing PFR‐mediated radical mechanism was predominant process. Experiments t‐butanol alcohol (TBA) aged as scavenger hydroxyl (⋅OH) have evidenced critical role generating reactive oxygens species (ROSs) solution, which catalysed oxidative MB.
