“…Another method of liquid sludge recycling is the energy-intensive process of aerobic stabilization; however, this method does not provide the required degree of disinfection to use this sludge as a fertilizer [7].…”

The article assesses opportunities for mitigating greenhouse gas (GHG) emissions in the waste treatment sector concerning biodegradable industrial waste. Authors describe GHG emissions sources and ways of their reduction, paying the specific attention to the stages of the life cycle, where, according to the official data, the most significant GHG flows are formed. Methods of systematization and statistical generalization are applied for analysis. The specified work is based on the data from various sources, including National Reference Documents on the Best Available Techniques, statistical and scientific publications. Russian Reference Documents are known in the Eurasian Economic Union and often discussed as a possible background for the future research in the field on Best Available Techniques and resource efficiency enhancement. The main GHG emission sources during the waste generation, neutralization, utilization, recycling and storage are roughly described. Authors suggest relevant approaches to GHG emissions reduction available from the economic and environmental points of view.

“…One of the ways to solve the problem of polluted and degraded urban soils is to use in green building of soils formed on the basis of sludge of water treatment facilities [7][8][9][10][11][12][13]. The water sludge has agrochemical properties that make it a sapropel: a sufficient content of organic matter, nitrogen, phosphorus, potassium, a favourable pH range.…”

Application of water treatment sludge for obtaining fertile soil

2021

The properties of soil obtained from the sludge of water treatment plants were investigated. A new recipe for obtaining soil from peat, river sand and sludge dehydrated with cotton dust was developed. The obtained soil is well structured, resistant to unfavourable mechanical and physical-chemical impacts. It is recommended for creating lawns, planting sports grounds, squares and road slopes. It can be used for filling landfills of solid municipal waste, for strengthening river banks and reservoirs, for soil protection, as well as for production of fertile soils in horticultural and urban farms, when growing vegetables, berries and flowers in greenhouses. The studied soil expands the range of plant nutrient mixtures, is based on the use of available raw materials, and is not difficult to prepare.

“…At the modern stage of chemistry and petrochemistry development, the processes of management of waste, including oil and sludge, are under strict complex requirements. These include reducing energy and resource consumption, increasing their technical and economic efficiency, ensuring environmental safety according to the world standards [1,2]. The existing technologies for oil sludge disposal often do not respond to the stated requirements, and have a negative impact on the environment by their own waste, which have to be buried.…”
