Opis:
e-Waste awareness and behavior of local Polish community has been examined. Specifically, the issue of selective waste electrical and electronic equipment (WEEE) collection has been explored. The main objectives of the research was to evaluate an attitude of the individuals towards e-waste treatment and to recognize the causes of low efficiency of the current WEEE management. The research was conducted among the inhabitants of a small town in Poland. Collected data may be useful while preparing household WEEE management systems. Over 52% of respondents, each was a representative of one household, conducted selective electrical and electronic equipment waste collection. Unfortunately, 12% (mostly young people aged 16-25, 9%) admitted that they threw e-waste mixed with general municipal waste. Another 12% (aged 18-25) claimed that they had never disposed of WEEE. Nowadays, the technology is developing very fast and small electronic devices are frequently exchanged, so the above mentioned statement is unlikely to be true. The research survey confirmed that further costs should be borne on educational activities which will raise people's awareness concerning WEEE threats and motivate them to collect e-waste selectively. The improvement of the management system increasing the number of e-waste drop off points, is necessary as well.

Odpady są integralnym elementem każdego gospodarstwa domowego, jak również przedsiębiorstwa. Rozwój technologii sprawia, że pojawiają się coraz to nowsze rozwiązania dotyczące gromadzenia odpadów. W artykule został poruszony temat podziemnego systemu magazynowania śmieci. Podstawę tej technologii stanowią pojemniki podziemne i półpodziemne, które zostały krótko scharakteryzowane w pracy. W gospodarce odpadami nieodłączny jest również aspekt logistyczny. Każdy transport musi być zaplanowany, monitorowany i kontrolowany, co wiąże się z licznymi kosztami, które można zminimalizować dzięki podziemnemu gromadzeniu odpadów.
The waste is integral element of every household and enterprise. Technology development makes new solutions regarding the collection of waste. The article discusses the subject of the underground garbage storage system. The basis of technology is underground and semi-underground containers. In the waste management, the logistic aspect is fundamental. Transport must be planned, monitored and controlled but it involves a number of costs. It can be minimized by underground waste collection.

Opis:
Khulna is the third largest metropolitan city in Bangladesh and a centre with intensive commercial and industrial activities. Rapid urbanization and increased migration of people from rural and coastal areas has put tremendous pressure on its existing solid waste management. The status of the existing municipal solid waste (MSW) management tiers such as generation, source storage, collection, on-site storage, transportation, and open dumping has been identified in this study. The daily generation of MSW is estimated as 520 Mg, of which food and vegetable wastes are the main components (79% on average). The major source of generated MSW is residential areas, which is 85.87% of total generation, whereas 11.60% in commercial areas, 1.02% in institutional areas, 0.55% in street sweeps and 0.96% in other areas. About 50% of total generated waste is disposed daily to the dumping site and the rest remains uncollected and unmanaged. Non-governmental organizations and community based organizations play an important role in primary collection, composting of organic wastes and medical waste management.

The authors present a unique possibility of utilizing hitherto unused and difficult-to-store types of waste such as dust generated during the extraction and treatment of a natural stone, and still difficult to recycle part of construction and demolition waste ??? residual mineral inert material. Stone dust mixed with residual mineral inert material, water, and binders in various proportions formed five types of mixtures which were transformed into manufactured aggregates using hyper-pressing. The properties of these manufactured aggregates ??? resistance to crushing and bulk density ??? presented on laboratory--basedsamples were similar to those of natural aggregates. The production of manufactured aggregates, the processing of unused types of construction and demolition waste, together with stone dust, fully comply with the rules of circular economics. The availability of stone dust has been checked based on data obtained by personally interviewing the authors in the quarries of the pilot regions of South Bohemia and Pilsen. Data on the amount of construction and demolition waste produced were obtained from the publicly available database of produced construction and demolition waste ??? Waste Management Information System (ISOH).

The cement process is one of the industries where energy is consumed intensively. High levels the amount of carbon dioxide emission reaches since the nature of the raw materials used in its production. At this point, using industrial wastes and by-products containing oxides such as calcium, silica, alumina, and iron oxides blended cement reduces energy consumption and carbon dioxide emissions. In this study, the effects of using ceramic sanitary ware waste (CSW) instead of clinker on the cement grinding stage were investigated. The grinding tests were carried out with clinker in a ball mill, according to grinding parameters as ball filling ratio, ball diameter, and grinding time by using Taguchi method for optimization of cement grinding condition. The reference and blended cements with CSW were determined compressive strength.

Opis:
The subject of the article is Living Labs – innovative platforms for meetings and exchange of ideas between specialists and users in order to develop and implement improvements oriented towards the needs of the latter. These modifications may concern not only products and services, but also, for example, the urban living environment. Living Labs are among those enterprises that approach sustainable development in a social context. Living Labs' practical activities relate directly to the everyday problems of local communities, and in the search for solutions, the opinions and ideas of their members are taken into account, therefore these platforms are potentially an important place helping to shape sustainable societies. The aim of this study was to present the benefits of living laboratories. This was done on the basis of the case study of Başakşehir Living Lab, an organization that conducts research on the efficient use of natural resources and the improvement of the quality of life in one of the districts of Istanbul, the city with the highest population in Turkey. The publication focused on the presentation of a series of workshops entitled "From electronic waste to design", the purpose of which was to show the possibility of reusing electronic waste. From the methodological point of view, the article was prepared on the basis of the authors' own experience related to the organization and conducting of workshops and a review of the literature, on the basis of which the theoretical foundation for the undertaken practical activities was outlined. The article also discusses the results of surveys which were carried out at the end of the series of workshops, which showed that such projects have a significant impact on building and raising the pro-ecological awareness of participants.
Tematem artykułu są żyjące laboratoria (Living Labs) – innowacyjne platformy służące spotkaniom i wymianie myśli między specjalistami i użytkownikami w celu wypracowania i wdrożenia ulepszeń zorientowanych na potrzeby tych ostatnich. Wspomniane modyfikacje mogą dotyczyć nie tylko produktów i usług, ale też na przykład miejskiego środowiska życia. Living Labs należą do tych przedsięwzięć, które traktują zrównoważony rozwój w kontekście społecznym. Działania praktyczne Living Labs dotyczą bezpośrednio codziennych problemów lokalnych społeczności, a w poszukiwaniu rozwiązań bierze się pod uwagę opinie i pomysły ich członków, dlatego platformy te są potencjalnie ważnym miejscem wspomagającym kształtowanie zrównoważonych społeczeństw. Celem niniejszej pracy było przybliżenie korzyści płynących z istnienia żyjących laboratoriów. Uczyniono to na podstawie studium przypadku Başakşehir Living Lab – organizacji prowadzącej badania nad efektywnym wykorzystaniem zasobów naturalnych i poprawą jakości życia w jednej z dzielnic Stambułu, miasta z największą liczbą mieszkańców w Turcji. W publikacji skupiono się na przedstawieniu serii warsztatów zatytułowanych: „Od odpadów elektronicznych do projektu”, których celem było pokazanie możliwości ponownego użycia odpadów elektronicznych. Od strony metodologicznej artykuł przygotowano w oparciu o własne doświadczenia związane z organizacją i prowadzeniem warsztatów oraz przegląd literatury, na podstawie której nakreślono teoretyczną podbudowę do podjętych działań praktycznych. W artykule omówiono też wyniki ankiet przeprowadzonych na zakończenie cyklu wspomnianych warsztatów, które wskazały, że takie przedsięwzięcia mają znaczący wpływ na budowanie i podnoszenie proekologicznej świadomości uczestników.

Opis:
This article attempts to find the strongest factors that impact waste management system costs. Case-based studies in three selected voivodeship Polish cities, Opole, Gdańsk, and Cracow found waste collection and transport, processing, and system management to be the dominant cost factors. The price of fuel, electricity and the rates of wages indirectly decide the determined management costs in the above-mentioned categories. The increase in waste management costs on a national scale observed in recent years is mainly from actions taken by companies to meet increasingly restrictive legal requirements. For example, the allowed time for waste storage has been shortened and the amount of environmental fees paid for waste landfilling has been increased. In addition, the obligation to watch the temporary storage and landfill as well as the implementation of fire protection rules. In the cities analyzed, the increase in waste management operating costs between 2017 and 2021 ranged from 41.3% for Gdańsk to 63.5% for Opole.

Opis:
For the past few decades, the electronic and electrical waste have been accumulating and piling on our lands and aside from posing some serious threat on our environment and our health. And with the technological advance and the rapid growing electronic demand and production there is the risk of accumulating even more unused valuable usable materials in our waste land-fields. Up to 2030, EU is forecasting about 74 million tons of e-waste, including washing machines, tablet computers, toasters, and cell phones. In 2022, more than 5.3 billion mobile phones were wasted whereas Li, Mn, Cu, Ni, and various rare-earth elements (like Nd, Eu and Tb, etc.) as well as graphite are actually found in the contents of many metal parts from wiring, batteries to their components. The main purpose aside from an environmental aspect is reserving the mineral used in this waste, as many of the crucial materials have a supply risk heavily depending on import. For instance, many of these rare earth elements (REE) are sourced from China; these REEs are used in many electronics that range from consumer products to industrial-use machines. This study is to review one of the desired methods that is via using bio-techniques to dissolve and recover as much as possible from main e-waste sources such as PCBs, spend batteries and LCD/LED panels. Microorganisms that are used for bioleaching process and their metal recovery aspects were compared in the second part. Future perspectives were finally added considering significant techno-economic environmental and social impacts.

Opis:
An overview of municipal solid waste management (MSWM) in Poland has been presented. The processes of waste generation and composition have been described and a comprehensive review of MSWM in Poland has been provided, covering some of the important aspects of waste management, such as the current status of waste collection, transport and disposal in Poland. An additional aim of the present work was to identify the potential barriers and the factors affecting waste management as well as provide recommendations for system improvement in Poland and other similar developing countries. An analysis shows that the state of municipal solid waste (MSW) management in Poland is not yet as developed as in many other EU countries. Landfilling is still the predominant method used for the disposal of MSW. Composting and incineration are also used but refer only to a small percentage of the total. According to the latest data (31st December 2014), around 84% of MSW was collected and transported and that ca. 53% was disposed of in landfill, ca. 7% was incinerated at waste-to-energy plants, ca. 11% was treated at organic waste recovery plants and 23% was delivered to sorting. The average generation rate of MSW was 293 kg/capita/year. Generally, recycling in Poland is on the increase, especially concerning easily collectable and recyclable materials such as paper, plastics, glass and metals. Around 37% of MSW collected selectively is recycled.

The paper discusses metal recovery from metallic wastes by means of pure chemical and biological leaching in an acidic medium. The research tested whether it is possible to remove Cu, Al, Sn and Ag from the dust formed during processing of electronic waste by means of Acidithiobacillus ferrooxidans. A laboratory flow bioreactor was designed and assembled for the purpose of the experiments. The experiments confirmed the effect of the bacteria on the dissolution of Cu, Al, and Sn, as well as different efficiency levels depending on the type of the leached material. The experimental results confirmed the positive effect of the presence of Acidithiobacillus ferrooxidans bacteria on the recovery of Cu, Al and mainly Sn into the leaching solutions from the leached dust.

In this study, hydration behavior of the magnesia waste, supplied from the electrostatic bag house of the sintering unit of MAS Company, Eskisehir-Turkey was studied to find out re-usability of the material as a source of magnesium hydroxide (Mg(OH)2) production. According to chemical and crystalline phase analyses, MgO content of the sample was determined as 49.9 wt% and consists of mainly raw magnesite (MgCO3), sintered magnesia-periclase (MgO) and small amount of serpentine (lizardite) phases. In hydration process, the reactivity of magnesium oxide determines the rate and extent of hydration of the sample. Therefore, the waste samples both calcined and uncalcined forms were hydrated in water and the efficiencies were compared according to sample source. The hydration experiments were carried out at temperatures ranging from 30 C and 80 C to evaluate the influence of temperature on particle morphology and surface areas of the products. The efficiency of the hydration was evaluated by using thermogravimetric (TG) and scanning electron microscopy (SEM) analyses. The test results suggest that the magnesia waste could be used as a source material for production of magnesium hydroxide.

The aim of the article is to present the physical and chemical properties of the refuse derived fuel (RDF) substrates, which have a significant impact on the energy recovery process in power plants. The experimental part includes technical (moisture and ash content, net and gross calorific values) and elemental analyses (sulfur, chlorine and mercury content), biomass and non-biomass concentration in the samples. In order to carry out the analysis of reactor slagging and fouling risk, chemical composition of the ash and characteristic ash fusion temperatures were determined. The waste samples are heterogeneous material and their properties are diversified – the moisture content ranges from 1.8 to 29.2 wt. %, the net calorific value from 17.231 to 28.307 MJ/kg, the ash content in the samples from 7.7 to 31.2 wt. %. The S content is in the range from 0.04 to 0.58 wt. %, the Cl content from 0.58 to 2.11 wt. % and the Hg content in the samples from 0.09 to 0.20 mg/kg. It can be observed, that the tested waste is a demanding fuel, because of its unfavorable fouling and slagging properties, which are directly related to the content of oxides with the basic properties.
