“…Construction waste is considered to be produced not only during the construction of new buildings but also during the demolition or reconstruction of existent buildings. The remaining materials used for the construction are disposed and new materials are obtained, for new construction [5,6,7,8].…”

Research on the use of construction and demolition waste as recycled aggregate for the production of new concrete has confirmed that they are environmentally friendly and constitute an alternative method of waste management. However, contrary to conventional concrete, no large applications of concrete made with recycled concrete have been made and there is still the literature studies of recycled aggregate properties are different, which indicates the need for further research on the properties of cements from waste. This paper presents and compares the results of a laboratory study on the properties of ordinary concrete (BZ), high-strength concrete (BWW), recycled aggregate concrete (REC). The tensile and compressive strength, modulus of elasticity of these concentrates were marked. The research results proved that the compressive strength of the concrete with recycled aggregate, compared with high-performance concrete, is much lower, but only slightly lower than for ordinary concrete. In turn, the tensile strength of the concrete with recycled aggregate is lower than that of high-performance concrete and ordinary concrete. These values, in the case of the compressive strength are as follows: REC -52MPa; BWW -68MPa; BZ -25MPa, whereas for the tensile strength, they reach: REC -4 MPa, BWW -6 MPa, BZ -5.1 MPa. Statistical analysis showed that the given parameters of the analysed concretes are indeed statistically different. Obtained results indicate that recycled aggregate may be aggregate of standard value and good mechanical properties, even better than of ordinary concrete. The application of recycled aggregate is considered to be a new approach in balanced construction and a superb solution to protect the environment.

“…Termiczne przetwarzanie osadów ściekowych jest jedną z metod unieszkodliwiania osadów ściekowych, jednak problem stanowią powstające popioły. Poważnym problemem zarówno z punktu widzenia ochrony środowiska, jak i ekonomii jest prawidłowa utylizacja popiołów powstających w wyniku spalania osadów ściekowych [42,43]. Ze względu na wdrażanie gospodarki cyrkulacyjnej i zrównoważonego rozwoju gospodarki odpadowej produkty uboczne powstające ze spalania osadów ściekowych wykazują przydatność w sektorze budownictwa, w tym w budownictwie drogowym [44], oraz w produkcji, m.in.…”

The chapter presents an innovative solution of gravity and gravity-underpressure rinsing the bottom of the retention chamber as soon as it is emptied of the sewage accumulated in it. Temporary accumulation of sewage in the retention chamber of the reservoir causes partial sedimentation of the solid phase suspended in the liquid. The ability to effectively rinse out sediments remaining at the bottom of the retention chamber is an important operational procedure for the proper functioning of the retention reservoir in the sewage network. The location of the rinsing chamber at the height of the maximum level of sewage filling in the retention chamber of the reservoir significantly increases the efficiency of rinsing the bottom of the retention chamber with the stream of sewage flowing out of the rinsing chamber.

“…There are also known patents: synthetic aluminosilicate aggregates [26,27] -combinations of aluminosilicates with low and high calcium content are used, construction elements are produced [26,28] -sewage sludge is combined with natural clay, foamed aggregate is produced [26,29]-firing of a mixture of raw clay or conifer shale with dehydrated sewage sludge at 2000ºC in a rotary kiln, production of lightweight aggregates [26,30] -creation of so-called "pellets" from sewage sludge and volatile dust from the combustion and sintering processes in a rotary kiln. Wójcik [31] [32] used fly ash from the incineration of municipal solid waste (MSWI) as a mix to produce ceramic bricks based on its characteristics. In addition, the fired bricks made according to the optimal mix ratio were characterized in terms of efficiency, phase transformation, microstructure, heavy metal leaching toxicity according to standards, XRD and SEM analysis methods and leaching toxicity.…”

The article presents research on the possibility of using troublesome waste such as: sewage sludge, mineral fraction of municipal waste <10 mm, stabilizer after mechanical-biological processing (MBP), carbon waste, glass -as a flux in the production of new light ceramic materials. Clay was used as the basis of the material. In order to determine the possibility of using individual materials to produce a ceramic material, the oxide composition of individual components was examined using the XRF method. XRF analysis showed the presence of quartz and aluminosilicates in the materials, which makes it possible to use these wastes to produce new materials. Then the waste was ground in a ball mill and mixed in different proportions by adding water and three different materials were obtained. Material A: clay, sewage sludge, waste water, glass. Material B: clay, mineral fraction of waste <10 mm, flotation waste, glass. Material C: clay, stabilizer after mechanical-biological processing, post-mining waste, glass. The materials were subjected to strength and absorbability tests. The most stable was Material B. The highest variability of properties was observed in Material A. On the other hand, a high heterogeneity was observed in Material C. The bulk density for all materials was 658kg/m 3 on average.
