The transformation and use of the biomass are of fundamental energetic and ecological
interest. The general objective of this review is to provide an overview of biochar (a major …

Organic, particularly nitro and chlorinated, contaminants are of great concern in ecosystem
for their contribution to environmental problems worldwide. Nitro contaminants are mostly …

Up-flow anaerobic sludge blanket (UASB) reactor belongs to high-rate systems, able to
perform anaerobic reaction at reduced hydraulic retention time, if compared to traditional …

Abstract Biochar/iron (BC/Fe) composites, such as nano zero-valent iron (nZVI)/BC, iron
sulfide/BC, and iron oxide/BC, have been developed and applied to deal with various …

The potential risk of various contaminants in water has recently attracted public attention.
Biochars and modified biochars have been widely developed for environmental …

Various nitroaromatic compounds (NACs) released into the environment cause potential
threats to humans and animals. Biological treatment is valued for cost-effectiveness …

This study investigated the dosage-effect of biochar on the suppressed mesophilic digestion
of oily sludge (OS) containing naphthalene (recalcitrant compound) and starch (easily …

The enhancement of zerovalent iron (ZVI) on anaerobic digestion (AD) has been proved, but
there are still some problems that constrain the large-scale application of ZVI, such as the …

Mining and smelting of mineral resources causes excessive accumulation of potentially toxic
metals (PTMs) in surrounding soils. Here, biochar-based sulfidated nanoscale zero-valent …

Recently, phosphorus recovery as vivianite from sludge digestion system has attracted
increasing attention because of its high recovery efficiency and economic value. However …
