Water scarcity and waste disposal become increasingly critical issues in many parts of the world, so it is important to analyze their impact on sustainable production practices. Brewery Birra Peja produces an impressive quantity of beverages each year, including 50 000 000 liters of beer, 2 100 000 liters of non-carbonated juices, and 800 000 liters of carbonated juices. However, this production process also generates a significant amount of water waste, with 485 120 000 liters of raw water being used in the process. The management of this water waste is an important environmental issue that the brewery needs to address to reduce its impact on the environment and ensure sustainable production in the future. Birra Peja could implement various strategies to reduce water waste, such as investing in more efficient production processes and equipment, reusing water in the production cycle, and treating wastewater before discharging it into the environment. Additionally, could explore the use of alternative sources of water, such as rainwater harvesting or recycled water, to further reduce their impact on the environment. The paper identifies the potential economic, social, and environmental implications of poor water and waste management in production processes. Finally, the paper proposes strategies for addressing these issues, such as improving resource efficiency, implementing circular economy principles, and adopting innovative technologies. Also taking steps towards sustainability and responsible water management can enhance the company’s reputation and increase its appeal to environmentally conscious consumers. Overall, while Birra Peja’s production output is impressive, it’s essential to address the issue of water waste to ensure the sustainability of their operations and minimize their impact on the environment.

Many enterprises face the issue with increasing own overhead cost and take an effort to reduce it, what is a base for using of outsourcing principles. Outsourcing is primarily used as a strategic tool for corporate resources optimizing. Enterprises decide to remove some supporting activities to external units, which can be provided with ensuring a higher quality and lower costs. These decisions result in increasing attention to a core business orientation and costs reduction. The main purpose of the paper is the cost savings quantification, what is supported by the research results focused on the use and the possibilities of outsourcing in Slovakian SMEs. There was proposed a general model for an economic efficiency evaluation for potential use of the outsourcing through determination of expected costs savings as a result of the research study.

Wiele przedsiębiorstw napotyka na problemy dotyczące wzrastających kosztów własnych i podejmuje wysiłek na rzecz ich redukcji, co stanowi podstawę do zastosowania zasad outsourcingu w przedsiębiorstwie. Outsourcing jest wykorzystywany przede wszystkim, jako strategiczne narzędzie optymalizacji zasobów korporacyjnych. Przedsiębiorstwa decydują się na wyłączenie niektórych obszarów pomocniczych do prowadzenia przez jednostki zewnętrzne, które mogą być świadczone przy zapewnieniu wysokiej jakości niskich kosztach. Decyzje te skutkują zwiększoną uwagą na podstawowej orientacji biznesowej oraz redukcją kosztów. Głównym celem pracy jest identyfikacja oszczędności kosztowych, co poparto wynikami badań ukierunkowanych na wykorzystanie i możliwości outsourcingu w słowackim sektorze MŚP. Zaproponowano ogólny model oceny efektywności ekonomicznej dla potencjalnego wykorzystania outsourcingu poprzez wyznaczane spodziewanych oszczędności kosztowych, jako rezultat pracy badawczej.

Background: The objective is to define on the basis of the literature as well as to test empirically the main factors that affect the cost saving of many retail chains, resulting from deliberate and conscious policies as well as organized activities in the area of product returns management. Methods: Based on a survey developed for the study, standardized interviews were conducted with representatives of trade corporations in the apparel industry in Poland. The data collected were analysed statistically. Results: The results of the statistical analysis showed that the analysed factors had a significant impact on cost saving. A company's ability to cooperate in the supply chain, limited for the purposes of the study to the distributor - retailer relationship, is relevant to the cost savings resulting from the policies of retail corporations in the area of reverse logistics. The integration of IT systems with suppliers and customers also influences the level of cost saving, as does collaboration within a team. Conclusions: To date, studies in this field have not been conducted in Poland. A particularly important element seems to be the relationship between cooperation in the supply chain and the possible savings which this can generate. This study contributes to the growing trend of research into reverse logistics and emphasizes the role of retailers and cooperation in the supply chain.

Wstęp: Celem jest zdefiniowanie na podstawie literatury oraz test empiryczny głównych czynników, które mają wpływ na osiągane przez sieci detaliczne oszczędności wynikające z celowej i świadomej polityki oraz zorganizowanego działania w zakresie zarządzania zwrotami produktów. Metody: Na podstawie opracowanej ankiety, przeprowadzono wywiady standaryzowane z przedstawicielami korporacji handlowych w branży odzieżowej na terenie wielkopolski i Ziemi Lubuskiej. Zebrane dane poddano analizie statystycznej. Wyniki: Wyniki analizy statystycznej pokazują, że na oszczędności istotnie wpływają analizowane czynniki. Zdolności firmy w zakresie współpracy w łańcuchu dostaw zredukowanej w badaniach do relacji dystrybutor – detalista mają znaczenie dla oszczędności wynikających z polityki korporacji handlowej w zakresie logistyki zwrotów. Integracja systemu IT z dostawcami i odbiorcami ma znaczenie dla poziomu oszczędności. Także dla osiąganych oszczędności z tytułu realizowanej polityki w zakresie zarządzania zwrotami ma współpraca zespołu. Wnioski: Studia w omawianym zakresie nie były dotąd przeprowadzane w Polsce. Szczególnie istotne wydają się zależności między współpracą w łańcuchu dostaw a możliwymi do osiągnięcia oszczędnościami z tego tytułu. Przeprowadzone studium wnosi wkład w rozwijający się nurt badań nad logistyką zwrotów i podkreśla rolę detalistów oraz współpracy w łańcuchu dostaw.

Ridesharing is a mobility concept in which a trip is shared by a vehicle’s driver and one or more passengers called riders. Ridesharing is considered as a more environmentally friendly alternative to single driver commutes in pollution-creating vehicles on overcrowded streets. In this paper, we present the core of a new strategy of the ridesharing system, making it more flexible and competitive than the recurring system. More precisely, we allow the driver and the rider to meet each other at an intermediate starting location and to separate at another intermediate ending location not necessarily their origins and destinations, respectively. This allows to reduce both the driver’s detour and the total travel cost. The term “A priori approach” means that the driver sets the sharing cost rate on the common path with rider in advance. An exact and heuristic approaches to identify meeting locations, while minimizing the total travel cost of both driver and rider are proposed. Finally, we analyze their empirical performance on a set of real road networks consisting of up to 3,5 million nodes and 8,7 million edges. Our experimental results show that our heuristics provide efficient performances within short CPU times and improves the recurring ridesharing approach in terms of cost-savings.

Prices of thermal and electric energy delivered to households are constantly increasing, and it will probably not change over the next few years. Due to this fact, people had been forced to find different ways to reduce costs of buying energy. The paper contains description of the most popular systems which are already in use from many years and some innovative systems which are implemented now, or which may be probably installed in nearly future – for example: internal combustion engines, Stirling engines, proton exchange membrane fuel cells, gas turbines, engines with Rankine cycle, etc. Each of mentioned above appliances is necessary to create CHP system which advantages and disadvantages are also described. In this publication, the most promising units have been compared to show their performance, flexibility, profitability and range of using ability. In this paper, approximate money and energy savings that may occur by using modern solutions compared to traditional systems are also shown. As always, during design and development of this kind of devices, there are a lot of problems related to various issues. Main problems and potential solutions have been also presented in this article. In summary further research, directions are suggested due to improve performance of this kind of systems.

An ergonomics improvement study was conducted on the visual inspection process of a printed circuit assembly (PCA) factory. The process was studied through subjective assessment and direct observation. Three problems were identified: operators’ eye problems, insufficient time for inspection and ineffective visual inspection. These problems caused a huge yearly rejection cost of US $298,240, poor quality, customer dissatisfaction and poor occupational health and safety. Ergonomics interventions were made to rectify the problems: reduced usage of a magnifying glass, the use of less glaring inspection templates, inspection of only electrically non-tested components and introduction of a visual inspection sequence. The interventions produced savings in rejection cost, reduced operators’ eye strain, headaches and watery eyes, lowered the defect percentage at customers’ sites and increased the factory’s productivity and customer satisfaction.
