“…Higher temperature and shorter heating and retention time (up to 105-500°C s -1 ) resulted in finer particles of biochar (50-2000 μm) [20]. Slower pyrolysis results in coarser particles of biochars [21]. …”

“…The most important properties of biochars include chemical composition, porosity and surface area, pH, and also surface functional groups. These properties can be "designed" by modifying the process of pyrolysis through temperature, heating and retention times [20][21][22] and also by modifying the properties of substrates for biochar production (physically or chemically). Depending on the properties of biochar substrates, the increase in pyrolysis temperature can result in the increase in surface area [23] and carbon content [24] in the obtained biochars.…”

Abstract. Pyrolysis of biomass residues from agriculture and food processing industry allows production of biochars with diverse physical and chemical properties for a wide range of applications in agriculture and environmental protection. Biochars produced from pelletized sunflower husks through slow pyrolysis in the range of temperatures (480-580°C) showed total carbon of 70.53%-81.96%, total nitrogen of 1.2%, alkaline pH (9.37-10.32), low surface area (0.93-2.91 m 2 g -1 ) and porosity of 13.23-15.43%. Higher pyrolysis temperatures resulted in lower biochar yields. With the increase in temperature the content of organic matter, nitrogen, Ca and Mg decreased whereas the increase in temperature resulted in higher contents of total carbon and phosphorus. Produced biochars showed potential for agricultural applications.

“…Many of them define the maximum allowable concentrations of pollutants in the managed sludge, which can vary depending on the adopted management method. EU directives which pertain to waste management methods and the definition of the maximum allowable concentrations are implemented in each country which joins the European Union [2, 17], owing to which emission standards are harmonized within the EU [5]. As a result, some national regulations are repealed, which may occasionally result in creation of legal gaps regarding regulations pertaining to specific standards for a given type of pollutants [14, 15].…”

This article presents the most popular methods of sewage sludge management and analytical techniques which could be a powerful tool in designing new sewage sludge management methods. Chemical analysis is also described as a vital point at the subsequent stages of technological processes control and sewage sludge quality assessment. It is also an instrument essential to maintaining control of processed sewage sludge introduced to the environment as ready-to-use materials. The sludge management method is conditioned by the compliance with legal acts concerning sludge management. The most important of these contain information regarding allowable concentrations of pollutants which can be released into the environment, and the most important declarations concerning sewage sludge management. Various analytical techniques and preparation methods that can be used during the monitoring of the managed and processed sewage sludge are described. The most important are chromatographic techniques, methods based on inductively coupled plasma, and mass spectrometry based methods.Graphical abstract

“…This approach allows for a selection of a direction for sludge treatment and disposal that will minimize the overall potentially adverse environmental impacts, on a case-by-case basis with costs having a secondary role [16]. Agricultural use of sewage sludge is usually considered as the BPEO, but it requires specific analysis of sludge and is dependent on many external factors and also many countries restrict the use of sewage sludge for food production due to potential risk of pathogens and transmission of contaminations [17]. Based on the statement that there is no universal technological solution which will consider local issues and sustainable development [18], it is difficult to develop clear guideline for management of sewage sludge in accordance with the rules of sustainable development.…”

Abstract. The structure of municipal sewage sludge management in Poland, along with the change in legal regulations, has changed radically. The management of sewage sludge is of key importance for environmental pollution and limiting the negative impact on human health. This article presents current legal policies in Poland, methods of commonly used sewage sludge management in European countries, discusses the selection of an appropriate method for the disposal of municipal sewage sludge and an analysis of the current state of sewage sludge management in Poland. In addition, the difficulties associated with the adaptation of sewage sludge management for the requirements of sustainable development are discussed. The article contains foundations, challenges and concerns related to the thermal transformation of municipal sediments. Also forecast and directions of activities in sewage sludge management in Poland are presented.
