This review examines the economic impact of Latin American regulations, strategies, and community involvement in mitigating the detrimental effects of mismanaged municipal domestic wastewater on public health, safety, and the economy. A systematic review and meta-analysis are conducted to assess the economic potential of reclaimed water in the region, utilizing various data sources and methodologies. The findings reveal that Latin America faces challenges in wastewater treatment, regulation, and resource management, affecting the market potential of reclaimed water. However, resource recovery initiatives present economic opportunities, including cost reduction, agricultural growth, energy recovery, and resource reuse.The study also highlights the lack of sanitation and waste- water treatment coverage data in many Latin American countries. By examining the commercial possibilities, regulatory frameworks, and environmental benefits of reclaimed water, this research provides valuable insights for sustainable water management and resource recovery policymakers, practitioners, and researchers. Furthermore, it emphasizes the economic advantages of utilizing reclaimed water and biosolids in Latin America, advocating for the implementation of strong regulations and policies to promote job creation and economic growth.

This paper presents the results of a cost-effectiveness analysis and a cost-benefit analysis for the production of X-type zeolites from fly ash. Positive results of the laboratory tests on the quality of zeolites derived from fly ash initiated a cost analysis on the production of this materials on an industrial scale. The cost-effectiveness analysis was conducted using the dynamic generation cost indicator (DGC ). The calculated DGC expresses the technical manufacturing cost of 1 Mg of synthetic zeolites. Whereas the cost-benefit analysis (CBA) was completed using the economic net present value (ENP V) and the economic internal rate of return (EIRR ) indicators. The calculated unit technical cost of producing 1 Mg of zeolites using an installation consisting of five reactors with a capacity of 25 m3 each is 211 EUR and is lower than the current market price of this product, including transportation costs. This proves the financial viability of the investment. The calculations of the economic efficiency of the installation (CBA method) show that it is fully economically viable to operate and use the products from a social point of view.

W artykule zostały przedstawione wyniki oceny efektywności kosztowej i ekonomicznej produkcji zeolitów typu X z popiołów lotnych. Pozytywne wyniki badań laboratoryjnych dotyczące jakości materiału zeolitowego otrzymanego z popiołów lotnych były podstawą do przeprowadzenia oceny kosztów ich produkcji w skali przemysłowej. Ocenę efektywności kosztowej przeprowadzono przy wykorzystaniu dynamicznego kosztu jednostkowego (DGC ). Obliczony wskaźnik DGC wyraża techniczny koszt produkcji 1 Mg zeolitów syntetycznych. Natomiast analiza kosztów i korzyści (CBA) polegała na obliczeniu ekonomicznej bieżącej wartości netto (ENP V) i ekonomicznej wewnętrznej stopy zwrotu (EIRR). Obliczony jednostkowy techniczny koszt wyprodukowania 1 Mg zeolitów na instalacji składającej się z 5 reaktorów o pojemności 25 m3 każdy wynosi 211 EUR i jest niższy od ceny rynkowej tego produktu, wliczając koszty transportu. Świadczy to o opłacalności finansowej inwestycji. Przeprowadzone obliczenia efektywności ekonomicznej instalacji (metodą CBA) potwierdzają w pełni opłacalność jej eksploatacji i wykorzystania produktów z punktu widzenia społecznego.

This work is a continuation and extension of previous socio-economic analyses of hard coal mines, which were conducted at the Central Mining Institute in the years 2013-2015. The paper presents the results of the economic evaluation of the hard coal mining sector in the years 2016-2018 using the Cost-Benefit Analysis (CBA) methodology. Used for the socio-economic assessment of hard coal mining, the CBA methodology enables the comprehensive evaluation of the functioning of this sector of the economy in Poland. In addition to financial aspects, which are important from the point of view of coal companies, it also included the social and environmental influence resulting from the impact of mines on the environ-ment. Direct data of operating costs and payments (including pub lic-law payments), incurred by the hard coal mining industry in Poland, was used. This data is obtained by Industrial Development Agency JSC, Branch Office Katowice as part of the "Program of statistical surveys of official statistics" – statistical survey "Hard coal and lignite mining industry". They were supplemented with data coming from com-monly available public statistics. For the analysed period the presented results indicate that the financial and social benefits resulting from the hard coal mining activity in Poland outweighed the financial, social and environmental costs generated by this industry. This confirms the desirability of further functioning of the hard coal mining industry in Poland, however, assuming effective restructuring activities that will result in lower costs of coal production.

Ocena strat ekologicznych, jakie powodują ścieki odprowadzane do wód powierzchniowych, stanowi podstawę do ustalenia efektu środowiskowego osiąganego dzięki oczyszczaniu ścieków. Ten efekt jest określany jako wartość strat unikniętych w środowisku wodnym dzięki odprowadzaniu do niego ścieków oczyszczonych. Oszacowanie tych strat nie jest łatwe i wymaga wcześniejszego ustalenia strat jednostkowych. W tym celu przeprowadzono analizę trzech metod szacowania wartości jednostkowego wskaźnika strat spowodowanych zanieczyszczeniem wód powierzchniowych – metody wskaźnikowej, metody wyceny warunkowej oraz metody ceny cienia. W rezultacie wykonanej analizy określono zalety i wady każdej z nich oraz oceniono możliwości ich stosowania w polskich warunkach. Wykazano, że metoda wskaźnikowa umożliwia szacowanie, na podstawie danych literaturowych, ogólnokrajowego wskaźnika jednostkowych strat spowodowanych zanieczyszczeniem wód powierzchniowych. Z kolei metoda wyceny warunkowej pozwala oszacować, na podstawie badań ankietowych, wartość tego wskaźnika w przypadku pojedynczej gminy. Metoda ceny cienia umożliwia natomiast określenie jednostkowego efektu środowiskowego, którego wartość odpowiada wskaźnikowi jednostkowych strat unikniętych w środowisku wodnym w rezultacie oczyszczania ścieków. W przypadku tego wskaźnika określono strukturę wpływu poszczególnych grup zanieczyszczeń zawartych w ściekach (azot, fosfor, zawiesiny, związki organiczne) na efekt środowiskowy. Wykazano, że największy wpływ na ten efekt ma usunięcie ze ścieków związku azotu i fosforu. Z porównania metod określenia wartości wskaźnika jednostkowych strat spowodowanych zanieczyszczeniem wód powierzchniowych wynika, że ze względu na dokładność oszacowania i możliwości określenia wartości i struktury wskaźnika jednostkowych strat w przypadku pojedynczej oczyszczalni ścieków, największe możliwości daje metoda ceny cienia.

Assessment of ecological losses caused by surface water contamination forms the basis for establishing the environmental benefit of wastewater treatment. This benefit is defined as the amount of losses avoided in the aquatic environment due to treatment of the discharged wastewater. Estimation of these losses is quite complex and requires prior determination of unit loss indexes. To this end, an analysis of the three methods for estimating the index value of the unit loss caused by surface water pollution was conducted, i.e. the index method, the contingent valuation method and the shadow price method. As a result, the advantages and disadvantages of each method were determined as well as their applicability under local Polish conditions was assessed. Based on literature data, the index method makes it possible to estimate the nationwide index of unit losses caused by surface water pollution. The contingent valuation method, on the other hand, allows estimation of the index value for a single municipality on the basis of interview surveys. Finally, the shadow price method facilitates determination of the unit environmental benefit, the value of which corresponds to the index of the unit loss avoided in the aquatic environment in consequence of wastewater treatment. For the latter, the structure of impact on environmental benefits of particular pollutant groups from the wastewater (nitrogen, phosphorus, suspended solids, organic compounds) was determined. The removal of nitrogen and phosphorus compounds was demonstrated to have the greatest effect. The comparison of methods for estimating the index values of unit losses due to water pollution demonstrated the shadow price method to have the highest potential in terms of its accuracy and capacity to estimate size and structure of the unit loss index for a single wastewater treatment plant.

Sustainable management of water resources requires leaving in the rivers a flow that ensures biological life. Since 2014, water authorities have been seeking to develop a methodology for determining environmental flows that are to reflect the inherently time-changing environmental water needs. The paper presents economic aspects of the implementation of environmental flows that will bring environmental benefits from providing the necessary amount of water for aquatic ecosystems as well as for water dependent ecosystems. However, on the other hand, they can cause significant costs for existing water users and limitations in economic use of water resources in the future. The cost-benefit approach is developed to estimate costs and benefits from introducing environmental flows in river basins. As the result the unit costs and benefits indicators for different water users are estimated and applied for the economic analysis in six study areas. The outcomes provide new information and methodological approach for decision-making about implementation of environmental flows.

This article addresses current issues concerning the risk analysis and functional safety management. Some cost-benefit analysis methods (CBA) are presented oriented on optimizing the safety-related solutions on example of functional safety technologies reducing risk based on programmable systems E/E/PE (PN-EN 61508) and SIS (PN-EN 61511). The importance of safety-related criteria, such as tolerability of risk (TOR) in the context of cost-benefit analysis (CBA), is emphasized to reach rational decisions as regards safetyrelated solutions to be sufficiently reliable, safe and preferably economically justified.
