ABSTRACT This research was designed to assess the level of awareness and knowledge of local residents concerning Solid Waste Management [SWM] in Duhok, Iraq. Primary data were collected from local residents through interview and questionnaire. A total of 60 questionnaires were completed by the respondents that were randomly selected. In order to determine whether the trash could be recycled, the study goal was to define the household solid wastes produced by the neighborhood, and to use this solid waste to produce energy i.e. waste to energy technology. The outcomes of a research done in a neighborhood of the Iraqi city of Duhok are presented in this study. In order to determine whether the trash could be recycled, the study's goal was to define the household solid wastes produced by the neighborhood. The outcomes are used to assess the recycling potential in other towns that are comparable to the one under study. These neighborhoods are situated in the city's most active and recent growing area. The goal of the current study was to estimate the volume and quality of municipal solid trash generated in Duhok City in 2022. The samples were gathered from various city neighborhoods and residences. The income levels of the participants in the generation of municipal solid waste were considered. The generation of solid trash in Duhok city still Food (51 %) of the solid waste produced, followed by (24 %) plastics.

This study examined the rainwater yields of some of the three regions, namely the inhabited cities of Duhok and Zaho, and the Kowashe area of Iraqi Kurdistan, which is considered to be an industrial area with many factories for many different industries. Compiled in a study of chemical and physical properties. This is in an agricultural area where different types of crops are grown and this was done by conducting several tests. For example, pH TDS, Ca and Mg concentrations, salinity, conductivity, turbidity, ammonia, CO2, and heavy metal content were measured. The results were compared with the standard values of the World Health Organization (WHO). Samples were collected in the regional center and on 22nd October 2022. This is believed to be the first rain of the season after three consecutive years of drought.

A crucial component and effective instrument for examining the general characteristics of water quality is the Water Quality Index (WQI). Among the most significant tourist destinations in the northern part of Iraq and Kurdistan are the resort areas surrounding Zakho city. In December 2021, water samples were taken from a number of tourist locations, including Dashttagh, Sharanish Waterfall, and Bahair Cave. For the samples that were obtained, this investigation comprised chemical, biological, and physical tests. According to the World Health Organization drinking water quality standards, we conducted this research to determine whether this water is suitable for use by people, animals, and agriculture. The results of the tests revealed that water samples taken from Sharanish Waterfall had the best water quality when compared to other sources. both Bahair Cave, and Dashttagh samples.

The objective of this study is the characterization of activated carbon prepared from hawthorn core natural residue which is a vegetation waste. By using zinc chloride (ZnCl2) as a chemical agent 40 for 25 hours at (25 °C) as a raw material in this work. The best conditions were determined to be a carbonization temperature of 400 °C for 1 hour and a maximum yield is 82 %. Different operational factors such as carbonization time and temperature were used to prepare activated carbon from hawthorn core stones, pH, ash content, density, humidity content, conductivity, iodine number, and methylene blue dye absorption were all investigated in the generated activated carbon. The obtained characterization of the activated carbon was performed by using scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive X-ray (EDX). Finally, the activated carbon synthesized in this study acquired good properties that enable it to play an important function in a variety of environmental applications, including eco-protection, water treatment, and wastewater treatment and it was compared to a commercial reference sample from the B. D. H Company in industrial applications.

Abstract The research work was aimed to preparation of different types from asphalt, Beji asphalt was mixed with polymers such as polystyrene, melamine-formaldehyde resins, poly methyl methacrylate. The amount of polymer added varied between (0.5, 1, 2, 3%) in addition to (1%) blow down and (1%) of anhydrous AlCl3. The materials were mixed and heated to (140±5 c◦), then exposed to microwave for a period of (5, 10, 15) minutes at (180 and 360) watt. After the reaction was completed, rheological properties were measured ductility, softening point, penetration and penetration index (PI), and compared with the non-modified asphalt. The process was repeated at the same condition but without using Blow Down and the time of reaction is (10) minutes, and rheological properties were measured ductility, softening point, penetration and penetration index(PI). The rheololgical properties of the sample obtained was studied by measuring (ductility, softening point, penetration and penetration index) and which almost similar to this of Iraqi standards is (89). In addition Marshall test of paving asphalt was compared for the samples. The results show that, the modified samples superseded that of the original asphalt in term of paving properties and characteristics
