Opis:
The industrial revolution taking place since the 18th century has brought the global economies to the stage of mass production, mass industrialization and spreading ideas connected with its efficiency. The most famous of its kind is Fordism and its modern variations called PostFordism or Neo-Fordism. We can still see traditional way of producing things in some parts of the world, and the leading economies are using Ford’s ideas or the modifications of the Ford’s concepts. But there is a question about the place of these models in the modern economy, especially because mass-production causes mass-waste and modern societies has woken up to the reality of the global pollution, climate change or just the simple fact that the amount of the raw materials is limited. The social mood is slowly changing so there should be a change to the way we produce and consume things as well. There is a question: can we proceed within existing models or should we think outside the box so we can invent more suitable way of looking at efficiency and effectiveness. The objective of this paper is to contribute to the discussion about the future of how are we going to produce things. It is based on the literature review considering Fordism and its variations, Product Life Cycle facing issues like pollution, massive waste and changes in modern economy, as well as on the case study of implementing waste reduction activities in the product’ design phase in the industrial plant based in one of the EU countries – Poland.

Opis:
A new act on maintaining the cleanliness and order in communes of 1 July, 2011, will become effective in Poland on 1 January, 2012. The act will come fully into force on 1 July, 2013. According to this act regulations, commune self-governments take over the obligations of the property owners concerning waste management, moreover, they become responsible for construction and maintenance of the infrastructure supporting recycling and waste disposal processes. The self-governments were granted a 1.5 year transition period to implement the act regulations.The introduced changes are an adjustment of Polish regulation to the European law. Only in Poland and Hungary local self-governments have not yet been responsible for management of waste generated in their areas.The article presents an analysis of the basic changes introduced by the act to the Polish system of municipal waste management. Presented are also the estimates of the mass of wastes collected on the territory of Poland with particular regard to the Małopolskie voivodeship. Calculations and forecasts were made on the basis of information collected by the Main Statistical Office (GUS) and commune offices, where systems similar to the one introduced by the act have been operating for several years. The act assumes that all citizens of Poland will be covered by a system of waste collection, but will also have to pay so called "garbage tax", which should translate into increased amount of collected wastes, especially in these communes where wastes collection system was faulty. In Małopolskie only in 30 communes the 100% of inhabitants have signed contracts for garbage disposal. In the communes where the modern municipal waste management system has been operating, the increase in the mass of collected wastes (for the first three years of system operation) ranged between 31% and 94% in relation to the mass collected in the year preceding the introduction of the new system, although over 90% of local inhabitants were covered by the previous system. As results from the analyses, after introducing the new act the amount of wastes collected in the Małopolskie voivodeship may increase from the level of 765,000 Mg (2010) to over 1.1 M Mg (1.4 M Mg according to less optimistic forecasts), assuming that all generated wastes will be collected (the same amount as in 2010). In some of the Małopolskie communes the estimated increase in collected municipal wastes may reach over 500%.

Opis:
The bottom waste obtained from bio-mass burning shows a huge variability of chemical and physical properties, depending on the kind of bio-mass, the type of a cauldron and burning parameters. The huge variability of the bottom ashes from the incineration plant and co-combustion of bio-mass makes it difficult to find any way to its management. In reality, only the bottom ashes from coal combustion and the small amount from lignite combustion are used, mainly in the building industry and in mining industry. The article presents the initial research, concerning the estimation of the properties of the bottom ashes obtained from bio-mass congestion in the fluidized-bed boiler to use them safely for the environment. To determine the influence of the tested waste on plants, a number of pot experiments have been conducted. The plants which have been used are recommended for phytotoxicity estimation, and are also used for biological reclamation.

Opis:
The demand for energy increases with the development of civilization. According to popular opinion, traditional energy resources, mainly fossil fuels (coal, oil, natural gas), are depleted and their use causes an increase in environmental pollution, mainly greenhouse gases. Therefore, renewable energy sources (RES), such as agricultural biogas plants, which are harmless to the world around us, are gaining importance. The European Union pays great attention to environmental protection and soil protection (organic fertilization with digestate, biogas plants) and energy issues. It emphasizes the increase in the share of energy from renewable energy in the total energy consumption. In EU countries, energy issues are regulated by relevant directives and the so-called Green and White Paper [1].

Opis:
The paper presents examples of installations for the mechanical and biological treatment of municipal waste in Poland. Each of the presented installations is defined as a regional municipal waste treatment installation (RIPOK). Their technological solutions and work efficiency have been compared in this study. In addition, the loss of waste mass as a result of processes occurring in the biological part of individual installations was calculated in the research. The paper refers to the National Waste Management Plan (KPGO 2022) regarding the circular economy. As intended by the circular economy, MBP installations will be transformed into installations that will treat selectively collected municipal waste and become Regional Recycling Centers (RCR).

Opis:
As a result of mining of deposits of mineral raw materials, spaces are formed in the rock mass, which get partially filled with roof rocks or by the backfill, most often sand. However, some voids remain in the rock mass, and can be used as a place to locate waste. The thesis analyses systems and operating conditions of mining deposits, in terms of the possible existence of spaces for filling in the LGOM mines. It was determined that the most probable option is to use goafs after mining the ore with a thickness of over 3 m in the last 5 years, with the systems of roof deflection and their partial lifting. Quantitative evaluation of the voids is based on the comparison of the subsidence over the extraction field and the volume of the extracted deposit. It has been proved that the existing voids provide the possibility of locating approximately 8 million m3 of waste in goafs. It is highly possible to locate further 11 million m3 of waste after obtaining positive results of the practical location of them and gaining relevant experience. The goafs after mining with hydraulic filling, goafs in the deposit of the thickness of up to 2 m and mined more than 20 years ago were recognized as useless for locating waste.
W wyniku eksploatacji złóż surowców mineralnych powstają w górotworze przestrzenie, które ulegają częściowemu wypełnieniu przez skały stropowe, względnie przez podsadzkę, najczęściej piaskową. Pozostają jednak w górotworze pustki, które stanowią zainteresowanie jako miejsce lokowania odpadów. W pracy przeanalizowano systemy i warunki eksploatacji złóż w aspekcie możliwości istnienia pustek do wypełniania w warunkach LGOM. Ustalono, że najbardziej prawdopodobne jest wykorzystanie zrobów po wybraniu rudy o miąższości ponad 3 m w ostatnich 5-ciu latach, przy systemach z ugięciem stropu oraz częściowym ich podsadzaniu. Ilościową ocenę pustek oparto o porównanie obniżeń powierzchni terenu nad polami eksploatacyjnymi i objętości wyeksploatowanego złoża. Wykazano, że istniejące pustki stwarzają bardzo prawdopodobne możliwości ulokowania w zrobach około 8 mln m3 odpadów. Są duże szanse na ulokowanie dalszych 11 mln m3 odpadów po uzyskaniu pozytywnych rezultatów praktycznego ich lokowania i zdobycia odpowiednich doświadczeń. Za nieprzydatne do lokowania odpadów uznano zroby po eksploatacji z podsadzką hydrauliczną, zroby w złożu o miąższości do 2 m i wybierane ponad 20 lat temu.

Opis:
The paper presents the algorithms for a flue gas/water waste-heat exchanger with and without condensation of water vapour contained in flue gas with experimental validation of theoretical results. The algorithms were used for calculations of the area of a heat exchanger using waste heat from a pulverised brown coal fired steam boiler operating in a power unit with a capacity of 900 MWe. In calculation of the condensing part, the calculation results obtained with two algorithms were compared (Colburn-Hobler and VDI algorithms). The VDI algorithm allowed to take into account the condensation of water vapour for flue gas temperatures above the temperature of the water dew point. Thanks to this, it was possible to calculate more accurately the required heat transfer area, which resulted in its reduction by 19 %. In addition, the influence of the mass transfer on the heat transfer area was taken into account, which contributed to a further reduction in the calculated size of the heat exchanger - in total by 28% as compared with the Colburn-Hobler algorithm. The presented VDI algorithm was used to design a 312 kW pilot-scale condensing heat exchanger installed in PGE Belchatow power plant. Obtained experimental results are in a good agreement with calculated values.
