Biochar-based water treatment systems as a potential low-cost and sustainable technology for clean water provision.
362
TL;DR: Seven hypotheses for future research are highlighted under three themes: design and optimization of bio char water treatment; ecotoxicology and human health risks associated with contaminant transfer along the biochar-soil-food-human pathway, and life cycle analyses of carbon and energy footprints of biochar water treatment systems.

Sabry M. Shaheen,Sabry M. Shaheen,Nabeel Khan Niazi,Nabeel Khan Niazi,Noha E.E. Hassan,Irshad Bibi,Irshad Bibi,Hailong Wang,Daniel C.W. Tsang,Yong Sik Ok,Nanthi Bolan,Jörg Rinklebe,Jörg Rinklebe +12 more
TL;DR: In this paper, the potential use of wood-based biochar (WB) for the removal of potentially toxic elements (PTEs) from water and wastewater has been discussed, and a review demonstrates the overarching scientific opportunities for a comprehensive understanding of using WB as an emerging biosorbent and a promising low-cost and effective material for the remediation of contaminated water.

Antibiotic resistance in drinking water systems: Occurrence, removal, and human health risks.
Edmond Sanganyado,Willis Gwenzi +1 more
TL;DR: It is concluded that combining UV-irradiation with advanced oxidative processes may enhance the removal of ARB and ARGs, while disinfection may promote horizontal gene transfer from environmental ARB to pathogens.

Synergisms between Compost and Biochar for Sustainable Soil Amelioration

- 01 Feb 2012
TL;DR: In this article, sustainable concepts for increased food production are urgently needed to lower pressure on soils, in order to reduce or prevent the negative environmental impacts of intensive agriculture, a key for such strategies is the maintenance or increase of SOM level inducing positive ecosystem services such as increased productivity, nutrient and water storage, intact filter capacity, rooting, aeration and habitat for soil organism etc.
Enhanced Lead Sorption by Biochar Derived from Anaerobically Digested Sugarcane Bagasse
TL;DR: In this paper, the authors examined the ability of two sugarcane bagasse biochars to remove lead from water and found that the maximum lead sorption capacity of DBC was about double that of AC (653.9mmol kg−1) and about twenty times higher than that of BC (31.3mmolkg−1), while surface adsorption was the principal mechanism of lead onto BC.
Fluoride Removal from Water using Bio-Char, a Green Waste, Low-Cost Adsorbent: Equilibrium Uptake and Sorption Dynamics Modeling
TL;DR: In this paper, low-cost pine wood and pine bark chars, obtained as a byproduct from fast pyrolysis in an auger reactor at 400 and 450 °C, were characterized and used as received for water defluoridation.

Impact of Biochar on Manure Carbon Stabilization and Greenhouse Gas Emissions
Natalia Rogovska,David A. Laird,Richard M. Cruse,Pierce Fleming,Timothy B. Parkin,David W. Meek +5 more
TL;DR: In this paper, the authors studied the effect of biochar and dried swine manure additions on changes in soil bulk density (D b ), total soil organic carbon (SOC), and emissions of N 2 O and CO, during a 500-d soil column incubation study.

Chemical evaluation of chars produced by thermochemical conversion (gasification, pyrolysis and hydrothermal carbonization) of agro-industrial biomass on a commercial scale.
TL;DR: In this paper, the 13 C NMR spectroscopy, scanning electron microscopy and energy-dispersive X-ray Spectroscopy and black carbon results confirmed these observations showing that hydrochars have lower proportions of aromatic compounds than biochars (less stable) but are rich in functional groups (higher cation exchange capacity) than biocharars.
