“…Sludge can be considered as a substrate for fertilization and soil recultivation, as they are a source of significant concentrations of macro-and micronutrients in particular nitrogen, phosphorus, potassium which are considered as components of organo-mineral fertilizers of different composition and purpose to improve soil quality (Paya et al, 2018;Zhu et al, 2004;Tymchuk et al, 2021;Tymchuk et al, 2022). However, SS tends to accumulate heavy metals (Wu et al, 2015;Hei et al, 2016) and organic pollutants (Clarke & Smith, 2011), pharmaceuticals (Khan et al, 2021;Boillot et al, 2008).…”

Increasing a large amounts of sewage sludge in Ukraine is an urgent environmental problem that requires the selection of an effective strategy for their disposal. The usage of sludge composting technology leads to the restoration of sludge as a resource and is cost-effective and environmentally sustainable compared to the method of landfilling. The purpose of this research is to carry out bioindication tests of growth substrates based on composted sewage sludge with the subsequent possibility of their usage in the technology of recultivation of landfills for municipal solid waste. The experiment was performed on four types of compost with different modifications of the natural sorbent - zeolite. During the experiment the average percentage of germination of polygamous ryegrass plants (Lolium perenne L.) was determined in the investigated substrates. The mass and length of the aboveground part of the plant and roots were also measured. The results showed that the addition of natural sorbent to substrates has a positive effect on growth and development of plants. This investigation was conducted in accordance with the current norms of national standards of Ukraine: DSTU 7369 (2013), "Wastewater. Requirements for wastewater and its sediments for irrigation and fertilization"; DSTU ISO 11269-1 (2004), "Soil quality. Determination of the effect of pollutants on soil flora. Part 1: Method for determining the inhibitory effect on a root growth"; DSTU ISO 11269-2 (2002), "Soil quality. Determination of the effect of pollutants on soil flora. Part 2: Effects of Chemicals on Germination and Growth of Higher Plants". The experiment was conducted on four types of compost with different modifications of the natural sorbent - zeolite in percentage amounts: 0; 2.5; 5; 7.5, dark-grey gilded soil was used as a control element. In the experiment, the average percentage of germination of polygamous ryegrass plants (Lolium perenne L.) on the studied substrates was determined. The mass and length of the aboveground part of the plant and roots were also measured. The first sprouts of ryegrass began to appear on the 7th day of the experiment. The highest average value on the seventh day of germination was 90% in the control sample with 5% of sorbent content and in K2 substrate in the sample with 7.5% sorbent content. However, the germination of plants in substrates K3 and K4 occurred later compared with substrates K1, K2, and control. For substrate K1 in the sample with a sorbent content of 5%, plant germination was the highest and was 100%. The highest average value of ryegrass stem length is observed in variant K4 in the sample with 0% zeolite content and in variant K1 in the sample without zeolite content the lowest average value of stem length was observed. The K3 and K4 variants have a more developed root system compared to other variants. Based on the obtained data it can be assumed that the most optimal universal component for creating a growth substrate is variant K3 (mixture of "newly picked" and "old" SS) which has not so developed aboveground part but has very branched root system that allows to adapt to various environmental factors and in combination with a small proportion of natural sorbents can be effective for the recultivation of MSW landfills, which in its turn minimizes the need to use a fertile soil layer.

“…To perform soil reclamation in one application, different combinations of sewage sludge, mineral wool, post-flotation lime, and mineral fertilisers were introduced into degraded soil. Furthermore, the publication of Tymchuk et al (2021) identified the main problems of the disposal of wastewater in Ukraine. The research discussed the possibility of using a sewage sludge-based substrate for the biological reclamation of affected areas.…”

The purpose of the article is to demonstrate practices used to supervise the use of sewage sludge for agricultural purposes. The presented research and conclusions are a trend analysis and are not to be used to penalise entities. Sewage sludge, which comes from the illegal dumping of wastewater into municipal wastewater by industrial plants, contains large amounts of heavy metals. Treatment plants transfer the sludge for agricultural use. Regulations specifically restrict the mode and conditions for such use of sludge. Methods: the research was carried out using a proprietary questionnaire, which is a supplement to the reporting questionnaire of the National Urban Wastewater Treatment Program implemented by the State Water Company "Wody Polskie". Results: The survey was conducted at 208 wastewater treatment plants in Poland. The results show that the majority of wastewater treatment plants do not properly supervise the process of introducing sewage sludge into the soil. They also lack supervision of how much heavy metals from wastewater are introduced into the soil. This means that there is a very high risk of contamination of agricultural soils. The results obtained could initiate a detailed analysis of this phenomenon in Poland. A comprehensive study of the scale of the practice and its current effects is required to determine the actual condition of soil treated with sewage sludge.

“…One of these unconventional energy sources is drainage water discharged from flooded areas. The problem of drainage water treatment is related to its purification from contaminants: ammonium ions (Malyovanyy et al, 2013;Sakalova et al, 2019), phosphates (Tulaydan et al, 2017;Tymchuk et al, 2020;Tymchuk et al, 2021), heavy metals (Kostenko et al, 2017) and their use as non-traditional energy sources.…”

The possibilities of using drainage water from flooded urban areas as a source of energy for heat supply of buildings located in these areas were considered. The use of heating technological workflows based on the utilization of drainage water heat with heat pumps was substantiated. A method was developed for determining the required energy potential of drainage water and for determining technological characteristics of the proposed workflows. A comparative analysis of various workflows was carried out and the advantages of the water-to-water heat pump along with the heat-insulated flooring system over other heat supply workflows are shown.
