“…The complex of preliminary experimental studies on the deposition in the form of struvite of model solutions and model ion exchange concentrate (Sakalova et al, 2018, Malovanyy et al, 2019 obtained by ion exchange extraction of the ammonium ions from aqueous solutions of natural zeolite and cation exchanger KU with an initial concentration of NH 4 + -N 40 mg/dm 3 installed: 1. The reagent method allows the removal of ammonium and phosphate at the same time, reaching the fraction of adsorbed ions up to 95% and up to 98%, respectively.…”

The article deals with the main methods of nutrient removal from wastewater, as well as presents promising technologies and techniques. Struvite was characterized by a complex phosphorus fertilizer. The influence of struvite on the processes of germination of cultivated plants was investigated. The possibility of creating a growth substrate as an inexpensive and effective alternative to the disposal of the man-made wastes that contain an organic component was identified. The composition of the growth substrate was selected to ensure its functional properties. The growth substrate was tested by bioindication. Subsequently, the modification of the substrate by adding natural sorbents.

“…Studies have aimed to apply environmental technologies to obtain nutrients and energy sources from industrial waste, biological objects, and organic pollutants (Kanda et al, 2019). In recent years, there has been a tendency toward reducing the use of phosphate, potash, and nitrogen fertilizers, associated with decreased natural resources required to produce such fertilizers.…”

This review article explores sustainable biotechnological strategies for converting sulfate compounds and lignocellulosic waste, focusing on using sulfate-reducing bacteria (SRB) and the valorization of agroforestry residues and sanitary sewage. SRB show potential in effluent treatment, mine drainage, and the removal of sulfate and heavy metals from wastewater, with their metabolic activity being influenced by factors such as pH, temperature, and chemical oxygen demand/sulfate (COD/SO4=) ratio. In the context of a sustainable bioeconomy, the challenge of converting lignocellulosic waste into value-added products is addressed through physical pretreatment techniques such as milling, extrusion, microwave irradiation, and ultrasound, which are efficient in valorizing waste from urban tree pruning. The article highlights the importance of bioreactors in transforming raw materials into desirable biochemical products, discussing different types of bioreactors, such as batch, continuous stirred tank, airlift, fluidized bed, upflow anaerobic sludge blanket (UASB), and bubble column, and their specific advantages and disadvantages. Sustainable sulfate reduction is the central focus, integrating the application of SRB and the conversion of lignocellulosic waste in a way that complements the objectives of the work and promotes a more cohesive flow in the summary. Thus, the interrelationship between effluent treatment strategies and waste valorization is emphasized from an environmental sustainability perspective, highlighting the relevance of this study in the broader context of a sustainable bioeconomy.
