“…They are known as fungicides, products sold up to hundreds $/kg in a market with 15 billion $/yr turnover . The fungicide properties of the pristine D and CP SBP have been reported, but not assigned to any component of these products. The finding that the ozonised SBP contain the potential fungicide oximes may prospect enhanced fungicide power by ozonised P0.2 fractions, compared to the pristine SBP containing 10 times lower amount of P0.2 compounds (Figure ).…”

Two hydrolysates obtained from anaerobic digestate and compost of a municipal bio‐waste treatment plant have been ozonizated at room temperature. This reaction yields two main products: biopolymers (30 % yield) whith molecular weights ranging from 100 to over 750 kDa, exhibiting remarkable surfactant properties, and small molecules with molecular weight ≤0.2⊥⊥kDa. The ozonised biopolymers have significantly different molecular weight distribution and much better surfactant properties compared to the pristine biopolymers. Their potential market value is estimated from 1.5 to 150 € kg−1 by comparison with commercial products. The small molecules are the bio‐based counterpart of commercial chemicals obtained from fossil sources. Their market value ranges from 0.6 to 3 € kg−1. Perspectives are discussed for the development of a bio‐based chemical industry built on the integration of biochemical and mild chemical technologies to convert biomass to value added products, and compared to the current model based on biochemical technology coupled to lignin incineration or pyrolysis.

Soluble bio-based substances (SBS) may be isolated from the anaerobic digestate of the organic humid fraction of urban waste; from the whole vegetable compost made from gardening residues and from the compost obtained after aerobic digestion of a mixture of urban waste digestate, gardening residues and sewage sludge. These SBS can be used as sustainable and efficient plant biostimulants in alternatives to the commercial products based on fossil sources such as the Leonardite. The present review summarizes the main findings obtained from recent studies accomplished with the SBS applied on several ornamental (Euphorbia; Lantana; Murraya; Hibiscus) and vegetable species (tomato; red pepper; spinach; maize; bean; wheat; tobacco; oilseed rape) with the aim to evaluate their effect on plant growth; fruit and ornamental quality. The main results from these studies show that the non-commercial SBS are more efficient than commercial fossil-based products; at equal applied doses; in enhancing plant growth; leaf chlorophylls; photosynthetic activity; fruit ripening and yield and aesthetic effect; improving flower and fruit quality and optimizing water use efficiency. Depending upon the plant species, increases of the plant performance indicators ranging from zero to 1750% are reported for the plants cultivated in the presence of SBS, relatively to the control plants cultivated in absence of SBS added to the cultivation substrate. The review suggests that biowaste recycling is a sustainable and environmentally friendly source of plant biostimulants, as an alternative to existing fossil sourced agrochemicals.

“…Alkaline hydrolysates from fermented biowaste can be applied as plant growth biostimulants or bio-regulators. Rapeseed studies have shown that hydrolysates used as fungicides against Leptosphaeria maculans reduced necrosis (by 42–56% and 31–37% for foliar and soil application, respectively) and biomass increase (by 9% compared to control) (Jindřichová et al 2018 ).…”

This literature review outlines the most important—agricultural and non-agricultural—types of sewage sludge management. The potential of waste sludge protein hydrolysates obtained by chemical sludge conditioning was reported. The discussed areas include acidic and alkaline hydrolysis, lime conditioning, polyelectrolyte dewatering and other supporting techniques such as ultrasounds, microwave or thermal methods. The legislative aspects related to the indication of the development method and admission to various applications based on specified criteria were discussed. Particular attention was devoted to the legally regulated content of toxic elements: cadmium, lead, nickel, mercury, chromium and microelements that may be toxic: copper and zinc. Various methods of extracting valuable proteins from sewage sludge have been proposed: chemical, physical and enzymatic. While developing the process concept, you need to consider extraction efficiency (time, temperature, humidity, pH), drainage efficiency of post-extraction residues and directions of their management. The final process optimization is crucial. Despite the development of assumptions for various technologies, excess sewage sludge remains a big problem for sewage treatment plants. The high costs of enzymatic hydrolysis, thermal hydrolysis and ultrasonic methods and the need for a neutralizing agent in acid solubilization limit the rapid implementation of these processes in industrial practice.
