COVID-19 has posed an unprecedented global public health threat and caused a significant number of severe cases that necessitated long hospitalization and overwhelmed health services in the most affected countries. In response, governments initiated a series of non-pharmaceutical interventions (NPIs) that led to severe economic and social impacts. The effect of these intervention measures on the spread of the COVID-19 pandemic are not well investigated within developing country settings. This study simulated the trajectories of the COVID-19 pandemic curve in Jordan between February and May and assessed the effect of Jordan’s strict NPI measures on the spread of COVID-19. A modified susceptible, exposed, infected, and recovered (SEIR) epidemic model was utilized. The compartments in the proposed model categorized the Jordanian population into six deterministic compartments: suspected, exposed, infectious pre-symptomatic, infectious with mild symptoms, infectious with moderate to severe symptoms, and recovered. The GLEAMviz client simulator was used to run the simulation model. Epidemic curves were plotted for estimated COVID-19 cases in the simulation model, and compared against the reported cases. The simulation model estimated the highest number of total daily new COVID-19 cases, in the pre-symptomatic compartmental state, to be 65 cases, with an epidemic curve growing to its peak in 49 days and terminating in a duration of 83 days, and a total simulated cumulative case count of 1048 cases. The curve representing the number of actual reported cases in Jordan showed a good pattern compatibility to that in the mild and moderate to severe compartmental states. The reproduction number under the NPIs was reduced from 5.6 to less than one. NPIs in Jordan seem to be effective in controlling the COVID-19 epidemic and reducing the reproduction rate. Early strict intervention measures showed evidence of containing and suppressing the disease.

Estimating the generation of e-waste in governorates is critically needed for sustainable and environmentally sound e-waste management in Jordan. The main objectives of the present study are to quantify and evaluate the annual e-waste generation in all governorates in Jordan and disposal practices. The present study comprises the information of e-waste as classified by the European Union Directive including six main categories (16 United Nations University key items). The survey targeted 15,883 households (12.52% females and 87.48% males), where primary data on e-waste generation and disposal methods were gathered, assessed, and quantified. Subsequently, the survey-based data collected from the study sample have been extrapolated to quantify an e-waste generation inventory for Jordan and the disposal methods using ArcGIS mapping. The study-extrapolated findings reveal that ~8,735,187 e-waste items (13 ktons) had been turned into e-waste and discarded by all households in 2018 in the 12 governorates in Jordan. Moreover, dumping of e-waste is still the dominant disposal method practiced by 58.4% of households in Jordan. The other disposal practices showed that granting of the waste EEE to others has the share of 16.6%; selling (10.7%); delivering the waste EEE for environmentally sound recycling (6.8%); and others practices represented 7.4%. Furthermore, the present study has played a vital role in e-waste awareness dissemination since the findings of the present study have been modeled and shown online by the Department of Statistics, Jordan through the link (https://arcg.is/1KzvjO). Finally, the challenges, barriers, and prospects of e-waste management in Jordan have been explored in the present study.

Background The reproduction number (R0) is vital in epidemiology to estimate the number of infected people and trace close contacts. R0 values vary depending on social activity and type of gathering events that induce infection transmissibility and its pathophysiology dependence. Objectives In this study, we estimated the probable outbreak size of COVID-19 clusters mathematically using a simple model that can predict the number of COVID-19 cases as a function of time. Methods We proposed a mathematical model to estimate the R0 of COVID-19 in an outbreak occurring in both local and international clusters in light of published data. Different types of clusters (religious, wedding, and industrial activity) were selected based on reported events in different countries between February and April 2020. Results The highest R0 values were found in wedding party events (5), followed by religious gathering events (2.5), while the lowest value was found in the industrial cluster (2). In return, this will enable us to assess the trend of coronavirus spread by comparing the model results and observed patterns. Conclusions This study provides predictive COVID-19 transmission patterns in different cluster types based on different R0 values. This model offers a contact-tracing task with the predicted number of cases, to decision-makers; this would help them in epidemiological investigations by knowing when to stop.

The present study outlines a cohesive compilation of analysis of the involvement of women in decision-making and leadership in the solid waste sector in Jordan. The socio-economic challenges have been catalyzed by the influx of Syrian refugees into the host communities and camps in Jordan. Hence, deterioration of municipal solid waste services have centered on and proposed that women engagement in the Solid Waste (SW) sector to provide opportunities that aim to improve livelihoods by producing an avenue for added income generation through the recycling and sorting scheme; as well as the cost revenue implications for the municipalities. Since 2015, projects added prospects for continued engagement of women and have drastically increased their involvement by filling management positions in the development and operation of municipal SW Transfer Stations (TSs), including heading the design and operation of the TS, and the recycling project. While 54 employment opportunities were created within North Shouneh SW pilot project; 37,794 women jobs of recycling and composting were made available by the cash for work initiative throughout 2016-2017, as well as, 60 women were employed in Zaatari camp. Moreover, when CBOs are directly involved, there has been more opportunity to engage women in employment in the solid waste sector.

The present study quantified the industrial water demand and reclamation and identified the scale of water-intensive industries in Jordan. Five industrial sectors including 395 industrial factories were surveyed by means of a structured questionnaire. The gathered data that were assessed included all industrial sectors, number of employees, the types and quantities of products, water demand, wastewater generation quantities, and management practices. Water demand and wastewater generation indicators (the water use and wastewater generation per product or per worker or per time) were determined for each of the responded groups of industrial sectors. The total industrial water demand and effluents generation in the five industrial sectors were pragmatically extrapolated and calculated. Moreover, the water reclamation and reuse potentialities were assessed from both environmental and economic perspectives. The results showed that the monthly industrial water demand per worker is 0.634 m3 for domestic use, while that for process use is varied between 0.07 to 21.38 m3/tons product. The results also determined the wastewater generation indicators, where the domestic use is generating between 0.515 to 0.628 m3 of wastewater per month per worker, while that for process use is between 0.04 to 12.45 m3/tons product. Moreover, the scenario of on-site treatment of 90% of the generated wastewater to be used as alternative water for 37.83% of total process water demanded by the grouped industries, showed viability where 9.7 million cubic meter of fresh water can be saved annually, and at least 25,953.60 tons CO2 equivalent emission can be reduced.

Water scarcity remains the major looming challenge that is facing Jordan. Wastewater reclamation is considered as an alternative source of fresh water in semi-arid areas with water shortage or increased consumption. In the present study, the current status of wastewater reclamation and reuse in Jordan was analyzed considering 30 wastewater treatment plants (WWTPs). The assessment was based on the WWWTPs’ treatment processes in Jordan, the flowrates scale, and the effluents’ average total dissolved solid (TDS) contents. Accordingly, 60% of the WWTPs in Jordan used activated sludge as a treatment technology; 30 WWTPs were small scale (˂1 × 104 m3/day); and a total of 17.932 million m3 treated wastewater had low TDS (˂1000 ppm) that generally can be used in industries with relatively minimal cost of treatment. Moreover, the analysis classified the 26 million m3 groundwater abstraction by major industries in Jordanian governorates. The results showed that the reclaimed wastewater can fully offset the industrial demand of fresh water in Amman, Zarqa, and Aqaba governorates. Hence, the environmental assessment showed positive impacts of reclaimed wastewater reuse scenario in terms of water depletion (saving of 72.55 million m3 groundwater per year) and climate change (17.683 million kg CO2Eq reduction). The energy recovery assessment in the small- and medium-scale WWTPs (˂10 × 104 m3/day) revealed that generation of electricity by anaerobic sludge digestion equates potentially to an offset of 0.11–0.53 kWh/m3. Finally, several barriers and prospects were put forth to help the stakeholders when considering entering into an agreement to supply and/or reuse reclaimed water.

Paper mill sludge (PMS) can be efficiently utilized to produce fuels and chemicals. However, wastewater is usually generated during the de-ashing step of the PMS for fibrous materials recovery. Per process requirements, the wastewater stream must be treated which results in an increase in the overall process production cost. Therefore, this research aims at reusing the wastewater produced during the de-ashing step as a substitute for freshwater addition during the conversion of PMS into ethanol. The advantages of this approach include reducing the amount of wastewater produced and enhancing the overall efficiency of the process. It will contribute to the circular economy of zero waste discharges. The results showed that 30% of the process wastewater can be recycled without affecting the enzymatic hydrolysis and ethanol fermentation. Hence, the amount of wastewater that needs to be treated is reduced by 30% resulting in a cost reduction of 22.5%. The results also showed that wastewater recycling minimized the energy demands in the distillation and evaporation units by 1206 kJ/kg. The energy reduction is due to the increase of metals and total soluble solids in the broth stream after fermentation. This process configuration enhanced the process economy, saved energy and managed waste streams.

To tackle climate change and secure energy supplies, many countries invest heavily on wind energy as it is a clean source and is becoming more cost effective with the technological advancement and increased capacity per unit installed. The investigation of the availability of wind resources is an essential step of any feasibility study of a wind farm project and is vital for securing financial resources. With this intent, the main aspects for designing a wind farm at Ajloun (north of Jordan) is investigated and wind energy potential is determined based on available wind data. Based on the site characteristic, the required infrastructure is highlighted, including the turbine array layout and the pattern of connections with the external transmission lines. The investigation of the feasibility of the project includes an appraisal of social and environmental consequences of constructing the wind farm project. The results show that the selected location for the wind farm is encouraging and has a promising profit potential. The findings estimate the annual electricity generation of the wind farm at 379659.51 MWh, with a breakeven selling point of around $30.03/MWh, at a highly competitive price. However, with an estimated selling price of $36.65/MWh on average, it will settle the interest rate demanded by the banks that have an internal rate of return of 7%. No major issues with geotechnical and environmental issues were identified with respect to the project.

This experimental research aimed to examine potential production and utilization of RDF derived from mixed municipal solid waste using bio-drying technology to be used as a substitute fuel for the traditional fuel currently used in cement plants in Jordan. The characteristics of RDF produced were identified and compared with limits and criteria set by some European countries. An economic model for RDF utilization in cement industry was created. The model proposes six different options resulting from adding RDF as a substitute fuel for the petcoke fuel currently used. A cost analysis for each option proposed was performed to estimate the economic and environmental savings of RDF utilization in cement industry. At the end of the bio-drying process, the mass of dried waste directed to the landfill was reduced by about 35%. In the case of the recovery of RDF materials from dried waste, the mass of waste to be landfilled was reduced by 69%. The bio-drying process allowed an increase in the heating value of waste (LHV) by 58% to reach 15.58 MJ/kg, as a result of the reduction of waste moisture. RDF produced had high calorific value, low water content, and satisfactory chlorine content. With regard to the concentration of the heavy metals, all of the RDF samples tested had lower concentrations than those values set by some European countries. The findings showed that adding 15% RDF as a substitute fuel, equaling 4.92 tons/h, to the fuel used in cement kilns will save 486 USD/h in petcoke costs, with 2.27 tons/h of CO2 being emitted into the atmosphere at a net saving of 389 USD/h.

This study presents a baseline assessment of carbon emissions in water utilities in Madaba, Jordan. The Energy Performance and Carbon Emissions Assessment and Monitoring Tool (ECAM) is applied in the present study in order to reduce indirect and direct emissions. Input data for the assessment included inter alia, population, water volumes, energy consumption, and type of wastewater treatment. The methodology focuses on the greenhouse gas (GHG) emissions and energy use that is directly associated with the utility operations covering the whole water cycle. The ECAM's Quick Assessment revealed that 89.7% of the energy is consumed in abstraction and distribution systems of water supply, whereas wastewater collection, treatment, and discharge consumed only 10.3% in Madaba. The detailed ECAM tool assessment results showed that total GHG emissions from the entire water and wastewater system in Madaba are approximately 28.122 million kg CO2/year. The water supply is the major contributor to GHG accounting for 62.4%, while 37.6% of GHG emissions result from sewage treatment, and are associated with treatment process requirements considered in this work, in addition to sludge transport from septic tanks to the wastewater treatment plant. The findings of this work can help the utility to undertake energy efficiency and GHG reduction measures.

It is undeniable that solid waste management in the Syrian refugees host communities was one of the most challenging services to be properly provided to the vulnerable communities by municipalities in Jordan. This paper presents the current waste generation and composition for both Irbid and Mafraq which are considered urban and rural areas, respectively, based on the urbanization index. Hence, the MSW composition in Irbid has relatively less organic content (51%) and more plastics (11%) and papers (12%) than that at Greater Mafraq (58% organics, 10% plastics, and 9% papers). On the other hand, the study reveals that the waste recycling (19%) and recovering (25%) in Mafraq Governorate are relatively much better than that in Irbid Governorate where waste recycling and recovering are 9 and 8%, respectively. The study presents a possible waste recycling model and opportunities to link the private waste-picking activities with the public SWM sector at the local municipality and dumpsite levels. A participatory model to create income generation potentials for the most vulnerable groups in the society (Jordanian Citizen and Syrian Refugees) is proposed based on the study findings.

Generation of different types and quantities of non-hazardous solid waste in the industrial sector are subject to different factors including the type of industry, production capacity, and raw materials involved in the production processes. The present study is a cross-sectional descriptive study which was conducted in 400 industries in Jordan in 2016. A structured questionnaire was used to collect all data related to the industrial processes, the types and quantities of waste generation, waste management practices and other general data. Moreover, quick-walk through assessment and observations were needed to get more details in some industries. The collected data were statistically analyzed using SPSS 19 software. Based on the results, the monthly generation rate of waste and daily waste generation per worker indicators were determined as 10,580.3 tonnes/month and 10.16 kg per day per worker, respectively. Also, it was found that the chemical industries followed by the agricultural and food Industries were the most waste generating sectors with 47.7% and 35.26%, respectively. Breaking down by NHIW category type, plastics (31.9%) and metals (28%) constituted about 59.9% of total waste generated. While only 28% of the industries showed recycling practice which is not very common in the surveyed industries, segregation of solid waste was reported by nearly 54.3% of industries within the five sectors. Moreover, the total waste generation was extrapolated based on the currently existing number of workers (93030 workers) in the five industrial sectors, and consequently estimated to equal 331743.7 tonnes per year. Finally, in total more than $71 million per year can be gained by expenses savings and recyclables selling of NHIW categories.

Hydrogen produced from chlor-alkali plants in Jordan is typically wasted and vented to the atmosphere. If it is recovered and utilized then it can viably play a significant role for process heat on site. This study demonstrates how cleaner production can be applied to the chlor-alkali industry, with focus on utilization of hydrogen as energy resource. A chlor-alkali based on membrane cell process, in northern part of Jordan, was examined as a case of reusing excess hydrogen produced. In the baseline scenario, 47% of produced hydrogen was used in HCl production, 10% in controlling pressure difference, and the remainder was not used (i.e. 43% of hydrogen was vented into the atmosphere). The proposed cleaner production option was to install a hydrogen boiler next to the existing fuel boiler and utilize the hydrogen to generate steam for on-site process heating purposes. The effectiveness of this cleaner production option was discussed in relation to its technical and environmental feasibility. On-site utilization of hydrogen was found to provide 34% of the total steam needed at the full capacity. This in return yields a saving percentage of around 33.37% and a payback period of 0.947 year. From environmental perspective, theoretically, carbon dioxide emission reductions can be up to 1810 tons based on the chlor-alkali productions pattern for 24 consecutive months.

The potential benefits of the application of a circular economy—converting biomass at Za'atari Syrian refugee camps into energy—was investigated in this study. Representative organic waste and sludge samples were collected from the camp, mixed in different ratios, and analyzed in triplicate for potential biogas yield. Numerous calorific tests were also carried out. The tangential benefit of the co-digestion that was noticed was that it lowered the value of the total solid content in the mixture to the recommended values for wet digestion without the need for freshwater. To test the potential methane production, the automated methane potential test system (AMPTS) and the graduated tubes in the temperature-controlled climate room GB21 were utilized. Also, calorific values were determined for the organic waste and sludge on both a dry and a wet basis. The maximum biogas production from 100% organic waste and 100% sludge using AMPTS was 153 m3 ton-1 and 5.6 m3 ton-1, respectively. Methane yield reached its maximum at a Vs sub/ Vs inoculum range of 0.25–0.3. In contrast, the methane yield decreased when the Vs sub/ Vs inoculum exceeded 0.46. The optimum ratio of mixing of municipal food waste to sludge must be carefully selected to satisfy the demands of an energy production pilot plant and avoid the environmental issues associated with the sludge amount at wastewater treatment plants (WWTPs). A possible ratio to start with is 60–80% organic waste, which can produce 21–65 m3· biogas ton-1 fresh matter (FM). The co-digestion of organic waste and sludge can generate 38 Nm3/day of methane, which, in theory, can generate about 4 MW in remote refugee camps.

Non-revenue water (NRW) is a major challenge for urban water security in Jordan. Quantifying of leakage is a difficult task in intermittent supply systems. This study aims to provide a structured analysis to determine the volume of leakage and its components in Madaba's water distribution network. The study also offers recommendations to reduce the physical losses as an important component of water losses through an infrastructure, repair, economic, awareness and pressure (IREAP) framework as a way of systematically engaging the NRW challenge in Jordan. The real loss sub-components were analysed using Burst and Background Estimates (BABE), and field records of the failures in the network. The potential impact of interventions to reduce losses were measured for efficiency/efficacy by analysing pressure management, chronic leakage detection surveys and response time minimization. The findings showed that Madaba's NRW amounted to 3.5 million m3 in 2014, corresponding to a loss of 2.8 million USD to the utility, of which 1.7 million USD is the cost of real losses. The reported failures in Madaba accounted for 37.2% of the total volume of real losses which can be improved by enhancing response polices and asset management, while the unreported failures constituted 26.6 and 36.20%, respectively, which could be reduced by pressure management and active leakage control.
