ABSTRACT
Consequent to the COVID-19 pandemic and the reopening of international borders, tourists are increasingly concerned about sanitation and hygiene practices in tourism destinations. There is an evident need to investigate how the COVID-19 pandemic has transformed tourist choices. This paper investigates the perceptions of hotel staff and tourists on the influence of inclusive water, sanitation, and hygiene (WASH) practices on tourists' hotel choices in Fiji. This study explores the value of Q-methodology through a case study of Fiji with data collected from 80 hotel staff and 75 tourists. The findings demonstrate that Q-methodology is effective in identifying three tourist types who have a strong interest in WASH impacts and aspects of their safety including concerns about how their visit impacts the local community and environment. Similarly, the Q method was useful in identifying four perspectives of staff understanding on WASH impacts that are significant to tourists' choice of hotel. The findings suggest a significant potential for hotel operators to enact socially inclusive WASH practices to enhance their appeal in the ‘new normal'. © 2022 Informa UK Limited, trading as Taylor & Francis Group.
ABSTRACT
This paper aims to critically review the production of alternative fuels through medical plastic waste. In the recent past, medical plastic waste has been disposed of and incinerated in the dumping yards, which is the main cause of the threat of infection and environmental hazards. Adopting proper waste management and the appropriate technology like the 5R's (refuse, reduce, reuse, repurpose, and recycle) may significantly improve the ecosystem. Moreover, the 5R's is a comprehensive approach that can be applied, either awareness of stakeholders or enforcement mandate and regulation by the government. The current review suggested the possible route for converting medical-plastic waste into drop-in fuel and value-added products to minimize the waste through suitable technology. In this, the pyrolysis technique plays an important role which is more ecologically friendly, effective and produces minimal pollutants. It has been observed that using COVID medical waste management (CMWM) technology, 70–80 % plastic pyrolysis oil (PPO), 10–15% bio-char, and gaseous fuel can be extracted. As per the ASTM, the extracted PPO is a potential feedstock for the CI engine fuel. This review work provides a suitable solution for CMWM and improves the quality of medical infrastructure for sanitation in a sustainable mode. © 2022 Elsevier Ltd
ABSTRACT
As a result of coronavirus (COVID-19) epidemic, the public has become actively involved in bodily sanitation. The "New Normal” lifestyle now focuses on cleanliness and disinfection to prevent the spread of germs. This research designed and programmed a microcontroller for a UVC disinfection system using an Arduino board as an open-source electronic platform operated with a motion sensor (PIR) and timer control module (RTC). The optical properties of an 8 Watt (W) UVC source were measured. The four UVC sources investigated had wavelengths ranging from 251 to 577 nm. A UVC wavelength of 251 nm eradicates germs but also destroys tissues and is harmful to humans. Experimental result showed that UVC intensity decreased with distance from the source according to the exponential decay function. A control system, installed inside a building to kill germs when there are no humans or pets, can control UVC light source operation with a maximum power of 2kW. Operational time can be adjusted by setting on the control case, while as an additional level of safety, the system can be turned off if a motion sensor detects movement. Movement detection distance at an angle of -90 to 90 degrees was recorded. Result gave 11 m detection distance at an angle of 0 degrees, with more than 3 m detection distance at -45 to 45 degrees, as suitable for installation above a door. This timer and motion sensor-operated UV germicidal ray system can be safely deployed to keep rooms germs free.
ABSTRACT
The global outbreak of SARS-CoV-2 has spurred a reassessment of Municipal Solid Waste management strategies and approaches. A significant need for sanitation and hygiene was accentuated for disease prevention and control with the onset of the pandemic. With an alteration of the status quo in waste management system, an unprecedented amount of face masks, protective equipment, and other biological wastes was generated in the form of Municipal Solid Waste. This upsurge of potentially infected wastes originated a risk of transmission amongst frontline workers. Furthermore, the potential contamination of Municipal Solid Waste was rendered as a legitimate threat due to improper collection practices, disposal and handling of solid waste. Several novel waste disposal techniques and waste management policies were also introduced during this period. However, the sanitation-policy making-occupational safety nexus remains inadequately explored under the prevalent COVID-19 scenario. Through the prism of shifting waste composition, this review offers a global assessment of existing solid waste management systems during the COVID-19 pandemic. The physiological and psychological hazards faced by the frontline workers were explored and instances of best-case and worst-case policies on solid waste handling were recorded. Modern methods of waste disposal and latest trends of policymaking were evaluated. A model study of unsupervised learning via Partition Around Medoids cluster analysis was undertaken to reveal underlying patterns of waste management policies. Although, the clusters were formed devoid of any socio-economic parameters, this study strives to indicate proof of concept and can serve as a precursor to advanced clustering studies. © 2023 The Author(s).

ABSTRACT
Continuity of key water, sanitation, and hygiene (WASH) infrastructure and WASH practices—for example, hand hygiene—are among several critical community preventive and mitigation measures to reduce transmission of infectious diseases, including COVID-19 and other respiratory diseases. WASH guidance for COVID-19 prevention may combine existing WASH standards and new COVID-19 guidance. Many existing WASH tools can also be modified for targeted WASH assessments during the COVID-19 pandemic. We partnered with local organizations to develop and deploy tools to assess WASH conditions and practices and subsequently implement, monitor, and evaluate WASH interventions to mitigate COVID-19 in low- and middle-income countries in Latin America and the Caribbean and Africa, focusing on healthcare, community institution, and household settings and hand hygiene specifically. Employing mixed-methods assessments, we observed gaps in access to hand hygiene materials specifically despite most of those settings having access to improved, often onsite, water supplies. Across countries, adherence to hand hygiene among healthcare providers was about twice as high after patient contact compared to before patient contact. Poor or non-existent management of handwashing stations and alcohol-based hand rub (ABHR) was common, especially in community institutions. Markets and points of entry (internal or external border crossings) represent congregation spaces, critical for COVID-19 mitigation, where globally-recognized WASH standards are needed. Development, evaluation, deployment, and refinement of new and existing standards can help ensure WASH aspects of community mitigation efforts that remain accessible and functional to enable inclusive preventive behaviors.
ABSTRACT
The design principles of decentralised wastewater treatment systems (DEWATS) make them a practical sanitation option for municipalities to adopt in fast-growing cities in South Africa. Since 2014, a demonstration-scale DEWATS with a modular design consisting of a settler, anaerobic baffled reactor (ABR), anaerobic filter (AF), vertical down-flow constructed wetland (VFCW) and horizontal flow constructed wetland (HFCW) has been in operation in eThekwini. A performance evaluation after the long-term operation was undertaken in 2019 by comparing the final effluent with national regulatory requirements. Despite limitations in characterising the raw wastewater, a comparison of the settler and final effluent quality indicated high (≥ 85%) removal efficiencies of total chemical oxygen demand (CODt), ammonium-N (NH4-N) and orthophosphate-P (PO4-P), 75% removal of total suspended solids (TSS) and 83.3% log10 removal of Escherichia coli. Lack of exogenous and endogenous carbon and high dissolved oxygen (DO) concentrations (> 0.5 mg·L−1) inhibited denitrification in the HFCW, resulting in 12.5% of the effluent samples achieving compliance for nitrate-N (NO3-N). Moreover, mixed aggregate media and low residence times in the HFCW may have also contributed to poor NO3-N removal. During the COVID-19 lockdown, an unexpected shutdown and subsequent resumption of flow to the DEWATS indicated a 16-week recovery time based on achieving full nitrification in the HFCW. Although design modifications are necessary for the HFCW, the installation of urine diversion flushing toilets at the household level will reduce the nutrient loading to the DEWATS and potentially achieve fully compliant effluent. Alternatively, the application of two-stage vertical flow constructed wetlands to improve denitrification should also be explored in the South African context. With an improved design, DEWATS has the potential to fill the gap in both urban and rural sanitation in South Africa, where waterborne sanitation is still desired but connections to conventional wastewater treatment works (WWTWs) are not possible. © The Author(s) Published under a Creative Commons Attribution 4.0 International Licence (CC BY 4.0).
ABSTRACT
Under the COVID-19 and other terrible environments workers are constrained to sweep campus and public area. Intelligent and driverless sanitation robot can solve the problem. Obstacle avoidance and garbage cleanup are its important functions. Based on the driverless sanitation robot project introduced by Sanda University, this paper carries out recognition of campus vehicles and improves its obstacle avoidance function. Through image processing, the object features of different environment and climate conditions are extracted, analyzed and recognized, so as to achieve more accurate recognition of campus vehicles.

ABSTRACT
The ongoing pandemic of the coronavirus disease 2019 (COVID-19) is a public health crisis of global concern. The progression of the COVID-19 pandemic has been monitored in the first place by testing symptomatic individuals for SARS-CoV-2 virus in the respiratory samples. Concurrently, wastewater carries feces, urine, and sputum that potentially contains SARS-CoV-2 intact virus or partially damaged viral genetic materials excreted by infected individuals. This brings significant opportunities for understanding the infection dynamics by environmental surveillance. It has advantages for the country, especially in densely populated areas where individual clinical testing is difficult. However, there are several challenges including: 1) establishing a sampling plan and schedule that is representative of the various catchment populations 2) development and validation of standardized protocols for the laboratory analysis 3) understanding hydraulic flows and virus transport in complex wastewater drainage systems and 4) collaborative efforts from government agencies, NGOs, public health units and academia.
ABSTRACT
Purpose: This study aims to discuss to what extent are WMPs practical tools for circular and sustainable waste management in universities, presenting, therefore, a case study of the usage of WMP in the Brazilian public universities and comparing this scenario with the international context. Design/methodology/approach: The WMPs were identified by online search and analyzed according to qualitative indicators (spatial-temporal distribution, year, extent and virtual availability), and through circularity and sustainability criteria, using a proposed checklist. Findings: Even being mandatory instruments, only 17% of the 103 public universities in Brazil had a WMP identified, and, among these plans, 55% were restricted to healthcare services waste, only 15% covered all university campuses. Although most of the available plans indicate measures for more sustainable waste management (e.g., recyclable waste collection on campus), they lack specific deadlines for presented goals on waste management, treating waste management at a more emergency pace than in well-structured long-term planning. Originality/value: Numerous studies have discussed waste management strategies for universities worldwide, but few have addressed the usage and structure of WMPs. A case study of the Brazilian situation in light of the international scenario is of great value in understanding the differences between universities in terms of waste management, and with strong potential to support the structuring of more solid environmental policies in universities, especially in developing countries.

ABSTRACT
This exploratory study examines how a team of three seventh grade teachers from a rural/suburban middle school in the Mid-Atlantic region of the United States adapted the WATERS curriculum for asynchronous online delivery. The study shows that many hurdles can be mitigated with intentional planning, dedicated resources, and professional development. Students who engaged with the WATERS curriculum made statistically significant gains in their watershed content knowledge. This study highlights both the barriers to transitioning instruction online and the resources that support this transition. The study also illuminates factors that decision-makers must consider as they craft policies related to continuing education remotely during times of crisis and school closures.
ABSTRACT
The present research aims to ascertain the views of the people in Russia, about their levels of awareness in terms of hygiene and personal care for protection against the coronavirus. Data for this research were collected through an online questionnaire developed by researchers using a quantitative research approach. A total of 439 people living in different districts of the Russian Federation were involved to the research based on simple random sampling. The data were analyzed using descriptive statistics including frequencies and percentages. Results revealed that the participants paid attention to not having close contact with other people to protect themselves against the COVID-19 pandemic. The findings also revealed that they wash their hands after visiting the toilet and stand one meter away from other people. It was also found that television is the mass medium through which they follow the information on personal care and hygiene-related to the COVID-19 pandemic most frequently.
ABSTRACT
The aim of the research was to reveal the school management process during the COVID-19 pandemic. The research was designed on the basis of case study in qualitative research paradigm. Maximum variation sampling was used in the study. As such, 15 school principals with various years of experience, serving at various school levels were included in the study. Data was obtained from a semi-structured interview form with 11 items. Inductive analysis was utilized in data analysis. The primary finding of the study was the precautions taken by school principals during the pandemic. These are physical precautions, informative precautions, and productive precautions. Another finding was that school principals made their best effort to fulfill their duties and responsibilities in-school, out of school, and regarding their leadership roles. Lastly, school principals problems mainly revolved around two groups: the resources of the school and students, and the decisions made, regarding educational and instructional processes.
ABSTRACT
Introduction: People with disabilities and older adults face a high risk of dying from COVID-19. Handwashing with soap and sanitizing surfaces were recommended to disrupt COVID-19 transmission. Yet, in many low-and middle-income countries (LMICs), these populations have inadequate access to water, sanitation and hygiene (WASH) and are not reached by public health campaigns. The Hygiene Behavior Change Coalition (HBCC) was set up to limit the spread of COVID-19 in LMICs. Twenty organizations working across 37 countries were funded to encourage populations to adopt recommended personal hygiene behaviors. This study aims to review the inclusion of disability, aging, and caregiving in HBCC grantee interventions. Methods: A COVID-19 Inclusive WASH Checklist, which incorporates core concepts of human rights, was developed to support the inclusion of disability, aging and caregivers in interventions. The Checklist was applied to 137 documents submitted to donors within the HBCC fund to assess inclusion. Eligible grantee programme documents related to HBCC-funded projects were identified between August 2020 and January 2021. Feedback was provided to grantees recommending how to strengthen the inclusion of disability, aging, and caregiving. Results: Most organizations identified people with disabilities, older adults and caregivers as target groups, but targeted activities to include them were scarce. Where efforts were made, immediate needs rather than rights were addressed. For example, the construction of accessible handwashing facilities featured more prominently than ensuring the participation of these groups. Examples of the coverage of core concepts in interventions included generating data with these groups and developing interventions accordingly. Limitations to inclusion were inconsistent organizational approaches, inability to monitor media campaigns, and inadequate coverage of disability and aging in donor's grant funding mechanisms. Conclusion: To ensure these populations benefit from efforts, they must be explicitly identified as target groups, with assigned actions that are monitored; efforts must go beyond accessible WASH services to ensure the meaningful participation of these groups. The COVID-19 Inclusive WASH Checklist supports this but requires further testing to assess its appropriateness and effectiveness.
