In 2016 4.94 million tonnes of tyres were produced. Each tyre eventually become waste and pyrolysis has been considered an effective way of utilizing scrap tyres for several decades. However, pyrolysis has failed many times because the process has a great energy demand and the quality of products is unstable or insufficient for commercial use. Usually plants are focused on the production of pyrolytic oil or char and the gaseous phase is only a by-product. In this paper the importance of composition and quality of pyrolytic gas is emphasized. The main chemical properties make this gas a valuable biofuel that may satisfy energy requirements of the whole process (except for the start-up phase). Available data from literature concerning composition and other features of the pyrolytic gas from scrap tyres obtained at temperatures up to 1000 °C are compared with experimental results. The quality of evolved gases is discussed in the context of the Industrial Emissions Directive (IED), too. Finally, an analysis of the mass balances obtained allows a decision about the business profile and profitability.

The Impact

The common methods of rapid implementation of commissioning of low-power private production should include the development of entrepreneurs on the basis of lease/purchase of empty industrial buildings, previously operating as part of an industrial facility located in the existing industrial area and represented or individual enterprises, or complex production of various industrial orientation, or provided for the reconstruction of a private enterprise already operating in a particular technogenic zone with an increase in its capacity.The possibility of placing diversifi ed industrial enterprises in a functioning industrial complex with the justifi cation of excluding the probability of the impact of industrial emissions of each of the newly placed or reconstructed facilities on the quality of products manufactured for the needs of the population is considered.The technical level of future production, the envisaged measures to prevent the formation and capture of air pollutants in General meet modern requirements for the safety of enterprises and for workers and for the population, the  optimization of working conditions.

Quality Of Products

While the quality of products is a competitive advantage for very small software development organizations, the usage of Software and Systems Engineering standards amongst such very small organizations is extremely low. A key factor in the literature explaining this lack of quality standards adoption is the perception by small and very small organizations that such standards have been developed for large multi-national companies and not with small and very small organizations in mind. The ISO/IEC 29110 standard is unique amongst software and systems engineering standards, in that the working group (ISO/IEC JTC1/SC7 WG 24) mandated to develop a new standard approached industry to conduct a needs assessment and gather actual requirements for a new standard as part of the standards development process. This paper presents a historical perspective behind the development of the ISO/IEC 29110 systems and software engineering standard and its constituent components, including the rationale behind its development and the innovative design of implementation guides to assist very small companies in adopting the standards. Further this paper will present an overview of the various parts of the ISO/IEC 29110 family and briefly present the plans for the future evolution of this series of standards.

In the conditions of growing competition on the market, organizations must ensure their sustainability, first of all, by implementing a systemic concept of business conduct in which the management is recognized as a powerful process of achieving high organizational performances. It is a concept that enables the meeting of the needs of consumers on a level different to their target value. In this sense, organizations must be structured in such a way as to fulfill certain conditions and criteria thanks to which sustainably high performance is created, which is, in fact, the goal of this research. Such performance is created as a result of the development of management within key areas of operation – the quality of products and services, production cost, speed to market, and innovating and developing such products and services. Success of such organizations greatly depends on the managers’ ability to develop and keep a talented workforce, which is a key factor in high performance development. By mastering change, outstandingly managing and controlling the future, assumptions for achieving business excellence and achieving high performance results are created. To confirm the starting hypothesis, the method of analysis, the method of synthesis and the method of multiple comparison and statistical test are used.

This study aims to measure the performance of services provided by regional companies such as PDAM to the community, the level of customer satisfaction is a reflection of the company's performance, a measurable data is needed that is taken directly to customers. With the help of the Importance Performance Analysis method, performance can be measured and easily understood by decision makers. So that poor performance can be seen and anticipated for future needs. Customer satisfaction of PDAM reaches 74.49% with the main priority that needs to be improved from the services provided are the ability of Social Media Admin Website Officers with performance indicator values of 2.93 and importance indicator values of 3.10.

Human health is largely determined by the influence of environmental factors, including the quality of foodstuff. Nutrition is one of the most important factors, so the application of modern knowledge about the energy value and fatty acid composition of basic foods, as well as the organization of a rational diet of people on this basis can significantly improve it. This article analyses data on the fatty acid composition of fat when using different feedstuffs in swine diets. The use of additives in animal diets in order to increase their productivity affects the quality of products, in particular the fatty acid composition of swine fat, which influences the physical and chemical properties and technological properties of food products. The role of saturated and polyunsaturated fatty acids in human and animal bodies, which play an extremely important role in metabolism, is described. The data on their content in fat and swine products as the main source of these substances in the human diet are summarised. The importance of a balanced intake of polyunsaturated fatty acids in the human diet is discussed, which contributes to the prevention of various diseases, and a review of the results of studies on the effect of various feedstuffs on the fatty acid composition of swine products is given, since the content of individual fatty acids that are not synthesised in the animal body is affected by feed quality and the presence of fatty acids in lipids of feed, which determine the quality of human foods.

The compaction quality of the subgrade is directly related to the service life of the road. Effective control of the subgrade construction process is the key to ensuring the compaction quality of the subgrade. Therefore, real-time, comprehensive, rapid and accurate prediction of construction compaction quality through informatization detection method is an important guarantee for speeding up construction progress and ensuring subgrade compaction quality. Based on the function of the system, this paper puts forward the principle of system development and the development mode used in system development, and displays the development system in real-time to achieve the whole process control of subgrade construction quality.
