“…This nding strongly supports the evidence of the bene cial effects of the biosolid. In addition, increased crop tolerance to Forl along with increasing biosolid amendment could be attributed to dose-dependent bene cial effects, such as improvement of organic matter, density and structure of soil, nitrogen and phosphorus supply to the plants, restoration of soil fertility and improvement of water circulation (Fischer et al 2020;Zaman et al 2019). Similar results were reported by X. who found that Zoysia japonica biomass was increased by 64-316% in biosolid treatments (15,30,60,120 and 150 tn/ha) as compared to the control soil.…”

Aims: A biosolid made from municipal sludge, acting as an organic fertilizer that enhanced plant growth and crop productivity, was evaluated for its effect on tomato growth and tolerance enhancement against the phytopathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici (Forl).Methods: Peat and/or two soil types were amended with mixtures of this biosolid (0, 80 and 160 tn/ha) in order to study the growth of tomato plants and their response to Forl, either under controlled conditions or outdoors in a net protected area.Results: The results showed that biosolid addition increased tolerance of tomato plants against the disease. There was also an increase of tomato fresh weight, root weight, stem height and leaf number compared to the Forl-inoculated control soils. Forl, at 5 weeks after tomato transplanting, caused higher disease index on plants grown outdoors in biosolid plus clay soil than in biosolid plus sandy soil, while the opposite occurred under laboratory conditions where higher disease index was recorded on plants grown in peat plus sandy soil than in peat plus clay soil. Conclusions:The ndings strongly support the evidence that this biosolid may act as an organic fertilizer and as a possible stimulant of tomato tolerance against Forl. Therefore, this type of biosolid, previously proven to be minimal ecotoxicological impact, should be considered for its possible use in agriculture according to the principles of circular economy and waste minimization.

“…Lystek technology in fact is a physicochemical TH process that utilizes high‐speed shearing, injection of alkaline solution by low‐pressure steam injection. In this method, thermo‐alkaline hydrolysis treatment occurs at a pH level ranging from 9.5–10, and a low temperature of 75°C with shear mixing (Brown et al, 2015; Elbeshbishy et al, 2014; Zaman et al, 2019).…”

Anaerobic codigestion (AnCoD) has attracted attention owing to its advantages over conventional anaerobic digestion, and attempts are still going on to develop methods for improving the efficiency of this technology. Mostly, addition of cosubstrates without applying a proper pretreatment cannot adequately enhance the performance of the digestion. However, there is a lack of a comprehensive study on different pretreatment methods specific to the wide range of cosubstrates. This review aimed to (i) categorize pretreatment techniques that have been developed for improving AnCoD, (ii) present the results of the studies on the effect of pretreatment on improving AnCoD, and (iii) provide a comparison between pretreatment methods and their application for different types of cosubstrates. The findings primarily validated the influence of pretreatment to enhance the process by increasing biodegradability, improved hydrolysis, reduced hydraulic retention time (HRT), and improved methane production. The five main categories of pretreatment employed in codigestion included the following: mechanical, thermal, chemical, biological, and hybrid pretreatment. Among them, mechanical and biological pretreatment have the most and least application in codigestion, respectively. Greater efforts are required on the application of biological pretreatment and cost–benefit analysis of different pretreatment options on the variety of the cosubstrates. Practitioner Points Pretreatment can significantly enhance biomethane production in anaerobic digestion Anaerobic codigestion along with pretreatment can further enhance the conventional anaerobic digestion of single feedstock Mechanical and biological methods have been the most and least practiced pretreatment options Selection of applicable pretreatment option to enhance methane production is subject to the type of cosubstrates in the system There is a research gap in evaluating the application of biological pretreatment for various types of cosubstrates
