Studies, about products obtained from agricultural wastes, have increased within the scope of zero waste studies. In the present study, activated carbon was synthesized using the olive pomace taken from the olive pomace processing plant operating with a three-phase process. The synthesized activated carbon characterization was performed using Scanning Electron Microscope (SEM), Fourier-Transform Infrared Spectroscopy (FT-IR), Brunauer – Emmett – Teller (BET), and X-Ray Crystallography (XRD) devices. Olive pomace activated carbon (OPAC) was used for the adsorption of dye from an aqueous solution. The adsorption efficiency of the OPAC was investigated. The pH value of dye solution (6-9), the amount of activated carbon (0.5 and 1.0 g/L), and initial dye concentration (600-1200 mg/L) were optimized. Also, adsorption kinetic and isotherm calculations were made. The optimum parameters were found as the original pH value (pH=8), OPAC amount of 1.0 g/L and the initial concentration of 1000 mg/L. The Langmuir isotherm model and the pseudo-second-order kinetic model were found as the most suitable models.","PeriodicalId":126818,"journal":{"name":"Environmental Research and Technology","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132406581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to evaluate the change of water quality according to the precipitation the samples were collected from 4 points in December and July months. pH, NO3, SO4, Cl-, total phosphorus, COD, SS, turbidity, some cations and metals were analyzed in the collected samples. It was determined that SS and turbidity parameters increased after precipitation and 98% of turbidity was caused by SS. Cl-, Na+, K+, Ca+2, Mg+2, SO4, TP were determined higher in the dry period. Although COD, TDS, EC, NO3 were higher in the rainy season, the difference between the two periods is not much. According to the water quality index, water quality was poor at all sampling points during the rainy season. In the dry period, good quality was also determined at only 1 sampling point. COD is the parameter with the greatest effect on effective weight and water quality. Irrigation water suitability was evaluated with the indices SAR, EC, %Na, MR, KI, PT and TH. River water is suitable as irrigation water in both periods according to SAR, %Na, MR, KI indexes. However, since the potential salinity (PS) value is greater than 3 µeq/L in the dry period, it is not suitable as irrigation water. Its total hardness value is >180 mg/L, so it is in the very hard water class.","PeriodicalId":126818,"journal":{"name":"Environmental Research and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128775170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Eurostat report “Recovery rate of construction and demolition waste” of 2022 shows how Italy, already in 2018, starts to recover about 98% of the waste from C&D activities considered non-hazardous, mainly for the construction of embankments and road foundations. The research, therefore, identifies in the use of file-to-factory technologies a possible way to extend the scope of application of the reuse of these resources to the realization of diversified and non-standard manufactures and components, in the perspective of a greater spread of virtuous practices of circular economy in the construction sector. In this sense, a process “algorithm” is described, designed to be scaled and replicated in different contexts for similar purposes.","PeriodicalId":126818,"journal":{"name":"Environmental Research and Technology","volume":"36 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116600531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kaya","doi":"10.35208/ert.1191003","DOIUrl":"https://doi.org/10.35208/ert.1191003","url":null,"abstract":"Fuel consumption is one of the biggest expense items in the operation of ships. Fuel consumption takes place via the main engine for propulsion of the ship and diesel generators for all other auxiliary engines. According to IMO rules, when a new machine system needs to be integrated into the ship, it is required to have low fuel consumption in terms of energy efficiency and emissions. The same is true for ballast treatment. Ballast water treatment systems (BWTS) are available in many different types of marine markets. Ship operators want to choose BWTS that will consume minimum fuel and operate at maximum efficiency. Therefore, in this study, fuel consumption under both IMO and USGC conditions, and hence the operational cost, is calculated if the UV-based BWTS system is integrated into a bulk carrier ship. While making this calculation, different generator loads and the use of different fuels (VLSFO, MGO and IFO380) used on the ships were taken into account. As a result, the highest cost is $9773 when the most expensive fuel, MGO, is used and operation is performed with a single ballast pump. In USCG mode, the minimum cost is $6382 and the maximum cost is $18929 under the same conditions. It is seen that if the fuel price increases to 1.4 $/kg, the cost of using BWTS in IMO mode can increase to $11392, and if it drops to 0.3 $/kg, the cost of using BWTS in IMO mode can decrease to $1826. It is seen that the highest cost can go up to $22066 and the lowest cost can go down to $3983, with the change of fuel prices in the use of BWTS in USCG mode. With the resulting formulation, with the power consumption of the BWTS and the diesel generator shop trail test fuel consumption values, researchers or shipping companies can repeat the calculations for all kinds of different fuels and different amounts of UV-chambers for variable ballast operations with different ballast tank capacities. Consequently, it is thought that this study is useful in determining the additional operational cost of UV-based BWTSs.","PeriodicalId":126818,"journal":{"name":"Environmental Research and Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130932539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In northern Nigeria, irrigation has long been identified as the key to achieving the much-desired increase in food production to meet the ever-increasing population. However, the existing irrigation schemes encountered several challenges coming from different dimensions including economic, social, environmental, institutional and technological. To attain sustainable crop production, this paper attempts to uncover the underline challenges confronting irrigation schemes in northern Nigeria that cut across sustainability pillars. The findings revealed that irrigation schemes contributed immensely toward achieving food security and improving the well-being of rural dwellers. However, the huge investment in large- and medium-scale irrigation schemes have resulted in massive economic losses. This could be attributed to their under-utilization, poor management and abandonment although few ones are performing remarkably well. The study recommends the need to adopt new water allocation and application methods that can improve water use efficiency, users-managers join approach (participatory), effective and competent institutions which include improved monitoring, evaluation and surveillance systems, frequent policy review to suit the situation, law enforcement, and timely sensitization and awareness campaigns.","PeriodicalId":126818,"journal":{"name":"Environmental Research and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130277604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphological, physical, and optical features of the catalyst were identified by several characterization analyses. The characteristic peaks associated with hexagonal phase of boron nitride were determined and high crystallinity of h-BN was confirmed by XRD analysis. Typical boron and nitrogen bonding peaks were detected in FTIR spectrum. Brunauer−Emmet−Teller specific surface area of the boron nitride catalyst was calculated as 1019 m2/g which was relatively high, supplying abundant active regions to interact with the target pollutant. In photocatalytic degradation experiments, 91.9% of tetracycline decomposition was achieved within 180 min while the adsorptive removal was calculated as 20%. The outstanding catalytic activity of h-BN catalyst was attributed to the high surface area and negatively charged groups on the surface which captured the photo-induced holes and inhibited the recombination rate of charge carriers. These findings highlight the potential application of h-BN in the field of photocatalytic processes.","PeriodicalId":126818,"journal":{"name":"Environmental Research and Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132896965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
