&NA; Phytoremediation is a green technique being increasingly used worldwide for various purposes including the treatment of municipal sewage sludge (MSS). Most plants proposed for this technique have high nutrient demands, and fertilization is often required to maintain soil fertility and nutrient balance while remediating the substrate. In this context, MSS could be a valuable source of nutrients (especially N and P) and water for plant growth. The aim of this study was to determine the… 
Trace Metal Accumulation and Phytoremediation Potential of Four Crop Plants Cultivated on Pure Sewage Sludge
Phytoremediation is a viable strategy to remove trace metal contaminants from sewage sludge but still is poorly investigated. The aim of this study was to quantify the trace metal removal of B.

TLDR
Results indicated that Z. mays and co-cropping could both degrade NP, and direct removal of NP from sewage sludge by plant uptake was negligible, as was downward movement of NP in the system.
Utilization of sludge derived from landfill leachate treatment as a source of nutrients for the growth of Nicotiana alata L.
TLDR
The results indicate that this sludge, in appropriate doses, can be used as an organic amendment for the revegetation of sanitary landfills.
Hemp-Based Phytoaccumulation of Heavy Metals from Municipal Sewage Sludge and Phosphogypsum Under Field Conditions
The aim of this study was to evaluate the ability of three hemp cultivars to accumulate heavy metals under sewage sludge (SS) and phosphogypsum (PG) application. The field study was carried out from
Capability of the Invasive Tree Prosopis glandulosa Torr. to Remediate Soil Treated with Sewage Sludge
Sewage sludge improves agricultural soil and plant growth, but there are hazards associated with its use, including high metal(loid) contents. An experimental study was conducted under greenhouse
Field testing phytoremediation of organic and inorganic pollutants of sewage drain by bacteria assisted water hyacinth
TLDR
Results showed that the highest metals removal efficiency was found in Cr, Pb, Ni, and Cu, and results showed the use of Bacillus safensis strain showed the higher percentage reduction for BOD, nitrates, sulfates, and phosphates.
Effect of Biowastes on Soil Remediation, Plant Productivity and Soil Organic Carbon Sequestration: A Review
High anthropogenic activities are constantly causing increased soil degradation and thus soil health and safety are becoming an important issue. The soil quality is deteriorating at an alarming rate
Sewage Sludge as N-Fertilizers for Crop Production Enabling the Circular Bioeconomy in Agriculture: A Challenge for the New EU Regulation 1009/2019
The fertilizer framework in the European Union has recently been reviewed by EU Regulation 1009/2019 that excluded sewage sludge from the list of the possible constituents of organic fertilizers
Evaluation of the environmental and plant growth effectiveness of a new substrate consisting of municipal sludge and fly ash.
TLDR
The results indicate that the new substrates containing 40-60% sludge exhibiting good physiochemical properties, are environmentally friendly, and suitable for landscape planting.

Trace element phytoextraction from contaminated soil: a case study under Mediterranean climate
TLDR
A positive correlation between the phytoextraction rate and biomass yield, extractable TE concentration and translocation factor (TF) and a negative relationship with Ca concentration in the soil is found.
Assessment of phytoremediation potential of native plants during the reclamation of an area affected by sewage sludge
TLDR
It was concluded that selected native plants are not only tolerant to adverse environmental conditions, but also contribute by various processes to the reclamation of sites affected by sewage sludge.
Comparative bioremediation of heavy metals and petroleum hydrocarbons co-contaminated soil by natural attenuation, phytoremediation, bioaugmentation and bioaugmentation-assisted phytoremediation.
TLDR
The results of this study demonstrated that the combined use of plant and bacteria was the most advantageous option for the treatment of the present co-contaminated soil, as compared to natural attenuation, bioaugmentation or phytoremediation applied alone.
Effect of wastewater sludge on growth and heavy metal bioaccumulation of two Salix species
Fast-growing tree species, such as willows, can benefit from sludge application. While sludges are good fertilizers, they may contain heavy metals which could reduce productivity and cause

Abstract In European Union countries, disposal sewage sludge on agricultural lands is restricted by directives. Large-area degradation of surface soils in Europe is a major challenge to maintain and
Phytotreatment of Sewage Sludge Contaminated by Heavy Metals and Pahs by Co-Planting Sedum Alfredii and Alocasia Marorrhiza
TLDR
It is shown that co-planting can reduce significantly the environmental risks associated with heavy metals and B[a]P in sewage sludge for further disposal, and is more effective than mono- planting at reducing concentrations of total Zn and diethylenetriaminepentaacetic acid (DTPA)-extractable Zn, Cd, and Cu in the sludge.

The use of reed canary grass and giant miscanthus in the phytoremediation of municipal sewage sludge
TLDR
Research results indicate that on account of higher yields, higher bioaccumulation, and higher heavy metal uptake, miscanthus can be selected for the remediation of sewage sludge.

TLDR
Plants and earthworm metal body burden offer much more information than metal concentrations and help to understand the potential for metal accumulation and large differences for BAF(earthworm-soil), from control or sewage-amended soil, for Cd and Hg were found.
