Drinking water treatment reduces or eliminates certain health risks and ensures appropriate water quality by removing physical, chemical, and biological pollutants. The treatment process’s increased need for energy, chemicals, and technological inputs raises the expense of producing water as well as its secondary environmental effects. The goal of this research is to use the water quality index (WQI) and life cycle assessment (LCA) to determine and assess the environmental effects of the Al-Hashimiyah water treatment plant (WTP) in Babylon City, Iraq. The water quality index was employed as a criterion for categorizing and treating water in accordance with fundamental water characterization variables using a weighted arithmetic index technique. The LCA was supported by the EcoIndicator 99 database and SimaPro 7.0 software. What makes this study unusual is the identification of two extra functional units related to decontamination, beyond the usual one cubic meter treated water. Samples of treated and raw water were gathered during a 25-month period, from March 2022 to March 2023, and were regularly tested. The results demonstrated that all chemical and physical characteristics (for both raw and processed water) met Iraqi criteria, with the exception of total suspended particles and electrical conductivity. According to LCA studies, certain environmental consequences grow as pollutant concentrations drop. Due to this, a more thorough analysis of the environmental performance of water treatment facilities is now required.

A comprehensive, high-quality product offered in the network of automotive suppliers must meet increasingly stringent environmental criteria and standards. The assessment of the environmental quality of a product must cover all stages of its life cycle, from "cradle to cradle", and must result in an improvement in the producer’s environmental performance. The paper identified, analysed and evaluated the environmental aspects, impacts and risks of individual phases of the production components life cycle of a passenger car, bumper, fender, and door. In the evaluation phase, progressive environmental management tools, LCA and the eco-indicator method were used in the case studies. Their combination for individual components created a methodological procedure that can be used to evaluate the environmental profile of other components of cars and other products in general.

Using the ICT-Thermodynamic Code program, thermodynamic parameters and combustion products composition of the Rocksplitter type, containing different masses of pytotechnic mixture and black powder, were evaluated. The eco-indicator was determined on the basis of numerical falsification results obtained using the SimaPro PhD version 7.2 of the Dutch company PreConsultants. The environmental impact analysis was performed at the combustion temperatures of the tested mixtures and at 298 K.

W ramach niniejszej pracy, stosując program ICT-Thermodynamic Code oszacowano parametry termodynamiczne i składy produktów spalania ładunków typu Rocksplitter zawierających różne masy mieszaniny pirotechnicznej i prochu czarnego. Na podstawie uzyskanych rezultatów falsyfikacji numerycznych, stosując program SimaPro PhD wersji 7.2 holenderskiej firmy PreConsultants, wyznaczono potencjalny wpływ na środowisko metodą Ekowskaźnik 99. Analiza obciążeń środowiska została wykonana dla temperatur spalania testowanych mieszanin oraz temperatury 298 K.
