Phosphorus (P) plays essential roles in crops growth. Natural mineral sources of phosphate
are non-renewable, overexploited and unevenly distributed worldwide, making P a strategic …

As with new technologies, plant nutrition has taken a big step forward in the last two
decades. The main objective of this review is to briefly summarise the main pathways in …

Ground coffee waste (GCW) was pyrolyzed to produce impregnated Mg biochar (Mg-
biochar) for the recovery of phosphorus from wastewater. Adsorption of phosphate (1 mM) …

This publication presents a simple and low-cost hydrothermal humification (HTH) treatment
of sewage sludge (SS) together with alkali ash (AA) and biomass for simultaneous …

Poor properties and high concentrations of heavy metals are still major concerns of
successful application of animal manure-derived biochar into the environment. This work …

A sequencing batch biofilm reactor (SBBR) were operated to investigate the phosphorus
uptake performance of biofilms under varying dissolved oxygen (DO) concentrations, the …

A municipal and a coal-coking industrial sludge (MS and CS) were separately co-combusted
with bituminous coal at a sludge mass ratio (SMR) of 10%–50%. Quartz, larnite, gehlenite …

Alum sludge from water treatment was calcined and extracted to synthesize high quality
boehmite and γ-alumina for phosphate removal. Synthesized boehmite and γ-alumina were …

Sulfur (S)-rich textile dyeing sludge (TDSS) with different chlorine (Cl) and phosphorus (P)
contents was incinerated at 900° C to determine interaction effects of Cl and P on the …

Phosphorus (P) can be effectively recovered from sewage sludge ash (SSA) by applying wet
chemical extraction techniques. However, considerable amounts of heavy metals can be co …
