“…However, sewage sludge tends to accumulate and concentrate heavy metals, organic contaminants and pathogenic organisms. The presence of such compounds, as well as excess nitrogen and phosphorus, presents a challenge in selecting the method of sludge disposal, both from an economical and environmentally perspective [Twardowska et al, 2004, Fijalkowski et al, 2017, Nebesnyi et al, 2019, Moroz et al, 2020. The use of sludge in agriculture is one of the most common methods of disposal in many EU countries.…”

The main ways of sewage sludge disposal in the European Union and Ukraine were considered. The main problems of sludge utilization in Ukraine were identified. Research on the possibility of using a substrate based on sewage sludge for biological reclamation of disturbed lands was conducted. The quality of the sludge from Lviv WWTP was determined. The best substrate composition for biological land reclamation was determined by using bioindication. It was established that the use of settled sludge observed inhibition of plant growth and development. Introducing additional components to the substrate, in the form of sorbents, makes it possible to increase the content of sewage sludge. Positive changes in plant growth and development when using a soil-based substrate, sewage sludge and sorbent were observed.

New catalysts B–P–V–W–Ox/SiO2 of gas-phase condensation of acetic acid from formaldehyde to acrylic acid on an industrial carrier of stable chemical composition (colloidal silicon oxide, Aerosil A-200) were synthesized. It is shown that the hydrothermal treatment of the carrier allows to increase the activity and selectivity of the catalyst in the reactions of aldol condensation of acetic acid with formaldehyde. It was found that the developed catalyst is effective in the condensation reaction of acetic acid with formaldehyde, which allows to obtain acrylic acid with a yield of 68.7% and a selectivity of 94.1%. The kinetic regularities of the reaction on this catalyst are established. According to the proposed kinetic equations, kinetic parameters are calculated that describe the condensation reaction of acetic acid with formaldehyde.
