Concentration of Selected Plant Nutrients and Target Elements for Phytoremediation and Phytomining in Biogas Digestate

Mycomining: perspective on fungi as scavengers of scattered metal, mineral, and rare earth element resources

“…biomass, which can also be used for energy production through biofuel synthesis 63 or anaerobic digestion for biogas production. 64,65 Most notably, it has the advantage of simultaneously remediating contaminated soils and harvesting valuable metals, minerals and REEs. 55 However, it is not directly comparable with traditional mining processes that extract and process high grade ores, which have high energy requirements and environmental ramications but also produce high yields.…”

Bio-fertilizers issued from anaerobic digestion for growing tomatoes under irrigation by treated wastewater: targeting circular economy concept

“…Furthermore, bio-fertilizers are eco-friendly, cheap, sustainable and have numerous advantages comparing to chemical fertilizers. They improve soil fertility and enhance plant growth due to their biological properties and nutrient contents (Garcia-gonzalez and Sommerfeld, 2016;Zaffar et al, 2020). In contrast, chemical fertilizers negatively affected the environment such as eutrophication, soil contamination and human health problems (Koh.…”
