In ceramic production, vast amount of green process waste is created. Green process waste in other words, sludge waste creates a big environmental problem. It can create water pollution as well as create environmental problems having a big physical change of the stored area., Therefore, the use of sludge waste in the process as raw material is vitally important. The research programme was carried out to use the green process wastes as raw materials in the recipes of various products in Kaleseramik Research and Development Center in Turkey. Firstly, the long term samples were taken in order to observe the fluctuation of the created waste. Then, the chemical and mineralogical characterization of sludge wastes was carried out by using XRF and XRD. Different recipes were prepared by using green process waste. The behavior and the phases of fired products were evaluated by using a double-beam optical non-contact dilatometer and XRD. SEM and EDX were carried out for microstructural and microchemical analysis. Finally; the physical, mechanical and color properties of waste added recipes; such as water absorption, linear shrinkage, breaking strength and chromatic coordinates were measured. The results showed that it is possible to develop wall tile body with suitable technological properties by using appropriate mixture of process wastes in the body composition. The usage of sludge waste eliminates environmental problems and also provides the cost advantages as a raw material input. The full results of the case study performed at Kaleseramik Factory is illustrated in details.

The article is a review of papers, presentations, expert opinions concerning a just transition of post-mining areas in the light of technical, economic, ecological and social aspects, which were the subject-matter of the International Scientific-and-Technical Conference, organized by the KOMAG Institute of Mining Technology in Gliwice, Poland and the IHP Hydraulics and Pneumatics Research Institute in Bucarest, Romania. The Conference participants concentrated their discussions both on the social effects of transition, on the economic aspects of activities concerning a collaboration of circummining companies as well as on technical and technological challenges in the mines already closed down or in those which are currently subject to the closing-down processes. Some possibilities of a reorientation of the mining plants towards generating and storage of green energy were presented. It should be borne in mind that a transition of the European Economy in the direction of more green and climate friendly is one of the most important objectives determined by the European Union. In particular, it is a big challenge for mining regions such as Silesia in Poland. The transition process includes a liquidation of underground workings and of the surface infrastructure and a series of indispensable activities oriented onto a restoration of the natural environment and a protection of mining plants areas against hazards which may occur after a termination of their operation. The article is ended with some information concerning a role research institutes in the just transition of post-mining areas and a new strategy of KOMAG as GREEN INSTITUTE.

EN

The article is devoted to the problem of safe supplies in crisis situations in selected organizations of the health care sector. An attempt was made to answer the question to what extent, for example, the implementation of the ISO 28000-based model can assist organizations in managing the security of the supply chain, especially in crisis situations. What actions should be taken to maintain the supply chain security management system or what solutions can be introduced to the identified processes affecting the functioning of the supply chain? The essence is to emphasize the role of the supply chain management system, based on specific requirements, in maintaining an appropriate level of security, especially during a crisis. To what extent can requirements focusing on the flow of process control activities ensure supply chain security?

Europejski "zielony ład" na rynku ciepła i chłodu

Polska zadeklarowała w 2020 r. przejęcie do realizacji bardzo ambitnego celu osiągnięcia 28,4 % udziału odnawialnych źródeł energii (OZE) w zużyciu końcowym ciepła i chłodu brutto do 2030r. Zwiększenie udziału OZE w rynku ciepła ma być realizowane przez koncesjonowane przedsiębiorstwa ciepłownicze. Przyjęty cel wynika z konieczności implementacji polityki klimatycznej Unii Europejskiej wdrażanej między innymi dyrektywą w sprawie odnawialnych źródeł energii tzw. „dyrektywy RED II”. W myśl przyjętej przez Unię polityki przyszłość mają tylko gospodarki oparte o wiedzę i inwestujące w najnowsze technologie ograniczające presję środowiskową. Dla Polski, borykającej się z problemem smogu, jest to właściwy kierunek zmian. Istotny wkład w realizację tej strategii ma transformacja sektora energetycznego stanowiąca element Europejskiego Zielonego Ładu. Unia Europejska zgodnie z przyjętymi założeniami chce być do 2050% kontynentem neutralnym klimatycznie. Dla Polskiego rynku ciepła to duże wyzwanie. Problemem w tym kontekście jest niski poziom udziału odnawialnych źródeł energii w polskim ciepłownictwie, stagnacja w przyroście źródeł OZE w ciepłownictwie w ostatnich latach i dominacja paliwa węglowego. Realizacja przyjętego celu w postaci zwiększenia udziału OZE w cieple i chłodzie wymaga bardzo dużych nakładów inwestycyjnych w przedsiębiorstwach, które jednocześnie muszą rozliczać się z drożejących uprawnień do emisji dwutlenku węgla. Należy jednak zauważyć, że Polska nie jest wyjątkową „czarną owcą”, która musi zmierzyć się z wyzwanie OZE w cieple i chłodzie. Wiele krajów świata, skoncentrowanych dotąd na energii elektrycznej dopiero zaczyna dostrzegać potrzebę zmian także w obszarze ciepła i chłodu. Aby ocenić na ile realne są cele zwiększenia udziału OZE w końcowym zużyciu ciepła i chłodu zapisane w Krajowym Planie na rzecz energii i klimatu konieczne jest spojrzenie wstecz jak również spojrzenie z perspektywy doświadczeń innych krajów. Tych, które charakteryzuje największy udział OZE w ciepłownictwie i chłodnictwie oraz tych, w których nadal dominują paliwa kopalne.

In 2020, Poland declared to assume the very ambitious goal of achieving a 28.4% share of renewable energy sources (RES) in the final consumption of gross heat and cold by 2030. Increasing the share of renewable energy sources in the heat market is to be implemented by licensed heating companies. The adopted goal results from the necessity to implement the European Union’s climate policy implemented, inter alia, by the directive on renewable energy sources, the so-called “RED II Directive”. According to the policy adopted by the Union, only economies based on knowledge and investing in the latest technologies reducing environmental pressure have a future. For Poland, which has to face with the atmospheric pollutants from burning fuel , this is the right direction of change. A significant contribution to the implementation of this strategy is the transformation of the energy sector as part of the European Green Deal. According to the adopted assumptions, the European Union wants to be a climate neutral continent by 2050%. It is a big challenge for the Polish heat market. The problem in this context is the low share of renewable energy sources in Polish heating, stagnation in the growth of renewable energy sources in heating in recent years and the dominance of coal fuel. The implementation of the adopted goal in the form of increasing the share of renewable energy sources in heat and cold requires very large investment outlays in enterprises, which at the same time have to account for more expensive carbon dioxide emission allowances. It should be noted, however, that Poland is not a unique “black sheep” that has to face the challenge of renewable energy in warm and cold. Many countries in the world, so far focused on electricity, are just beginning to notice the need for changes also in the area of heat and cooling. In order to assess how realistic are the goals of increasing the share of renewable energy sources in the final heat and cold consumption set out in the National Energy and Climate Plan, it is necessary to look back as well as from the perspective of the experiences of other countries. Those with the highest share of renewable energy in heating and cooling, and those still dominated by fossil fuels.
