Comprehensive installation for wastewater treatment coming from the fish processing in the SUPERFISH plant in Ustronie Morskie, Poland, includes utilization of wastes which arise during working of this installation. This paper presents results of research on pyrolysis process of PE waste coming from the plant with the addition of dewatered sediments as well as post-flotation fats. Cementation was applied for utilization of secondary waste left alter the pyrolysis process. The results of examinations were approximated with equations applying the method of the central point. Next. the equations were verified. Results of the research showed that pyrolysis is effective in neutralization of examined waste, and secondary waste after the pyrolysis process after solidification is not dangerous for the environment.

The general aim of the paper is to indicate the key role played by banks in Schumpeterian innovative evolution. It includes formal modelling of innovative evolution of financial subsystem of an economy which goes beyond routine behavior of banks deprived of innovative, financial strategies. Moreover this paper studies an impact of innovations in financial sphere of modified Debreu monetary economy on its real sector and, specifically, on social welfare. Thus the paper main aims are to prove that pro-innovative banks may intensify innovative evolution and to specify the sufficient conditions to guarantee the preservation of the rules of circular flow for a consumption sector within the innovative changes in banks behavior.

This paper describes the analyses of the fatigue life of the asphalt pavement reinforced with geogrid interlayer under traffic loading. Finite Element ANSYS package with using nCode applications, as well as macros specially designed in APDL programming script and VBA were used to model the considered problem. Our analysis included computation of stress, fatigue life, damage matrix and rainflow matrix. The method applied was the one of fatigue calculation: stress – number of cycles in short S-N. On the basis of the performed high cycle fatigue analysis, the influence of the location of the used geogrid and of its bond with asphalt layers on the fatigue life and the work of the asphalt pavement structure were determined. The study was carried out for three temperature seasons i.e. spring and fall (assumed as one season), winter and summer. The variability of the traffic conditions were taken into account by assuming weekly blocks of traffic loading. The calculations were made using the real values of loading measured in field tests on the German highways by means of HS-WIM weighing system. As a result of the performed tests, it was proved that the use of geogrid-reinforcement may prolong the fatigue life of the asphalt pavement. However, it is required that: the geogrid should be located in the tension zone as low as possible in the structure of the asphalt layers. Moreover, it is necessary to provide high stiffness of the bond between the geogrid and the asphalt layers.
