Innovative Use of Eco-Enzymes for Domestic Wastewater Purification

The rapid pace of urbanization and the resultant increase in waste generation have significantly escalated the challenges associated with managing organic waste. In line with contemporary sustainable practices, it is imperative to recycle and repurpose waste effectively. This study investigates the use of eco-enzyme, an environmentally friendly product derived from fruit and vegetable scraps, along with natural sweeteners, in the treatment of domestic wastewater. The study assessed the impact of eco-enzyme concentrations at 15% and 20% over a five-day period. Results demonstrated that treated wastewater met irrigation standards after the treatment period. Parameters such as acidity, dissolved solids, biochemical oxygen demand, chemical oxygen demand, and microbial counts were analyzed. The 15% eco-enzyme solution reduced biochemical oxygen demand by 90.54% and chemical oxygen demand by 83.33%, while the 20% solution achieved reductions of 94.20% and 86.34%, respectively. Dissolved solids levels were reduced to 412 ppm and 422 ppm for the 15% and 20% solutions, respectively, and microbial counts decreased significantly. However, the study is limited by the short duration of the treatment period and the scope of the parameters analyzed, which may not fully capture the long-term effectiveness and broader environmental impacts of eco-enzyme use. This research underscores the potential of eco-enzyme technology in enhancing wastewater treatment processes, promoting environmental sustainability, and alleviating the burden on waste management systems. The eco-enzyme production process is straightforward and accessible, involving the fermentation of kitchen waste, and can be readily adopted in both urban and rural settings. Further research is recommended to optimize the fermentation process, reduce digestion time, and explore the broader applications of eco-enzymes in fields such as agriculture and domestic cleaning.

An Investigation of Work Precarity Among Paid Domestic Cleaning Workers in Switzerland

An Investigation of Work Precarity Among Paid Domestic Cleaning Workers in Switzerland

(In)visible by Design: An Analysis of a Domestic Labor Platform

Since the rise of platform labor, food delivery, and ride hailing workers have become a visible part of cityscapes, unlike platform workers in the domestic sector. The invisibilization and economic devaluation of reproductive tasks, especially in the private sphere, has a long history.Although platforms are not likely to yield a radical transformation in this sector, qualitative changes concerning the invisibility of work outsourced by households can be observed. In this contribution, we draw from the analytical framework of (in)visibility of/in platform-mediated work and map it against our research findings on a key platform in domestic cleaning in Europe, including netnographic data and interviews with workers and clients. Using the framework as a heuristic tool leads us to a more nuanced understanding of (in)visibility in platform-mediated cleaning in perceptible, institutional, and individual terms. Moreover, we argue that the interrelations between these three layers of (in)visibility offer novel insights for making sense of worker organizing and collective action, the practices related to leaving the platform, and the issue of workers’ occupational identity of domestic cleaners. As such, the study contributes to the current debates on platform labor and domestic work, including the value-visibility relation and the role of digital platforms therein.

Solar Panel Cleaning Robot

In this project, various studies revolving around how dirt and dust affect the performance of solar panels depending upon different regions, as different areas have different soil compositions and how they are different from one another. A new way of approach to the domestic solar panel cleaning system, researchers have proposed many ways to improve and classify the object and present it in an image in the past. However, there have few projects related to domestic cleaning of solar panels. Due to the inconsistencies in cleaning especially in region where rain is not the most convenient option for cleaning. On continuous using of solar panels, a layer of accumulated dust particles is settled on the surface of solar panels or PV panels which affect the result of decreasing in efficiency by 50 %. By cleaning on regular intervals it decreases this soil loss. Various data have been collected which shows the importance of domestic solar panel cleaning for future generation.

Precarious employment and mental health in the Belgian service voucher system: the role of working conditions and perceived financial strain.

Jobs in domestic cleaning are often conceived as 'precarious employment' (PE)-i.e. a multidimensional concept referring to accumulated adverse characteristics of employment due to workers' weak bargaining position. Against this background, the Belgian service voucher system (SVS) was implemented aimed at creating formal and stable, subsidized domestic services jobs. The current study assesses the relationship between PE and mental health (WHO5) in the Belgian SVS, accounting for the potential mediating role of working conditions and perceived financial strain at the household level. We analysed a cross-sectional sample of 1,115 Belgian SVS domestic cleaners, collected in 2019 through an online survey. A mediation model was estimated. The crude effect of PE on adverse mental health was strong (ß 0.545-S.E. 0.063). However, 50% of the association between PE and mental well-being was mediated by work task characteristics (quantitative demands, physical demands, task variation and autonomy) and 25% by household-level perceived financial strain. The remaining direct effect of PE on adverse mental well-being is ß 0.066 (S.E. 0.032-25% of the total effect). These findings are the first based on the Belgian Employment Precariousness Scale (EPRES-BE) and are consistent with earlier-made-but seldom simultaneously tested-assumptions on the mechanisms relating PE to adverse mental health-i.e. involving direct associations and indirect associations via adverse working conditions and material deprivation. Based on the results, we recommend more democratic and higher-quality management practices in the SVS, in addition to higher wages and working time reduction.

Cleaning up our disinfectants: usage of antimicrobial biocides in direct-to-consumer products in Australia.

In supermarkets and chemists worldwide, consumers are faced with an array of antimicrobial domestic cleaning and personal hygiene products purporting to kill germs and keep people safe. Many of these proven active ingredients (biocides) encourage the development of antimicrobial resistance (AMR) in microbes and microbial populations, in turn increasing the likelihood of AMR infections. In order to understand and address the selective pressure towards AMR posed by the unrestricted use of biocides, it is necessary to understand which biocides are most frequently found in consumer products and the current regulatory framework that governs their use. In this research we survey the biocidal active ingredients in the major categories of cleaning and personal care products available from supermarkets and pharmacies in Australia, and comment on the regulations that dictate how these products are tested and marketed. Benzalkonium chloride and ethanol were the two most prevalent antimicrobial biocides in this study, while triclosan, which is banned in several jurisdictions, was found in a small number of products. In Australia, many antimicrobial consumer products are regulated for efficacy and safety under the Therapeutic Goods Act, but the potential to drive microbial adaptation and AMR is not considered. Overall this survey underscores the broad use and light regulation of antimicrobial biocides in products available to the general public in Australia, and provides an information resource to inform further research and stewardship efforts.

Classifying the non-metabolic demands of different physical activity types: The Physical Activity Demand (PAD) typology.

Different physical activity types vary in metabolic demand (intensity), but also in non-metabolic physical demand (balance, co-ordination, speed and flexibility), cognitive demand (attention, memory and decision making), and social demand (social interaction). Activity types with different combinations of demands may have different effects on health outcomes but this cannot be formally tested until such demands can be reliably quantified. The present Delphi expert consensus study aimed to objectively quantify the cognitive, physical and social demands of different core physical activity types and use these scores to create a formal Physical Activity Demand (PAD) typology. International experts (n = 40; experts in cognitive science, psychology, sports science and physiology; 7 different nationalities; 18 male/22 female; M = 13.75 years of disciplinary experience) systematically rated the intrinsic cognitive, physical and social demands of 61 common activity types over 2-rounds of a modified Delphi (expert consensus) study. Consensus (>70% agreement) was reached after 2 rounds on the demands of 59/61 activity types. Cognitive, physical and social demand scores were combined to create an overall non-metabolic demand rating for each activity type, and two-step cluster-analysis was used to identify groups of activities with comparable demand profiles. Three distinct clusters of activities were identified representing activity types with low (n = 12 activities; e.g. domestic cleaning), moderate (n = 23 activities; e.g. tai-chi) and high (n = 24 activities; e.g. football) total non-metabolic demands. These activity types were then organised into a formal typology. This typology can now be used to test hypotheses about if and why physical activity types with different combinations of cognitive, physical and social demands affect health outcomes in different ways.

Platform adaptation to regulation: The case of domestic cleaning in Europe

While online platforms were initially applauded for improving services in a range of sectors, they are currently being criticized for ignoring laws and regulations. We analyse the evolution of Helpling – the largest domestic cleaning platform company in Europe – by focusing on the ways that Helpling has adapted its platform to regulations in five national contexts (France, Germany, Ireland, the Netherlands and the United Kingdom). Using data on changing Terms and Conditions, we show that Helpling initially tried to introduce a single business model across Europe, but quickly started to adapt to national regulatory contexts. Informed by arguments on ‘varieties of capitalism’ in Europe, we base our case study on a comparison of the different national trajectories pursued by Helpling.

Understanding the Hidden Emotional Labour of Migrant Women Doing Domestic Cleaning Work in England

Abstract This essay explores the emotional labour of women migrants working as domestic cleaners in a small city in England. Drawing on qualitative data gathered through in-depth semi-structured interviews, the essay foregrounds the narratives of a group whose perspectives have not been widely captured. In order to provide a good service, cleaners in the sample modified and mobilised their emotions, conveying friendliness and expressing empathy when faced with clients’ vulnerabilities. Framing domestic cleaning as relational, ‘intimate labour’ allows a better understanding of the role of migrant women in providing practical and emotional care. The analysis contributes to studies of migrant emotionality by situating cleaners’ emotional labour in the context of their transnational lives.

Path discovering in maze area using mobile robot

Robotic maze pathfinding problems deal with detecting the correct route from the start point to the end-point in a virtual maze environment consisting of walls. Automated robot mobility is a significant feature, which enables a mobile robot to traverse a maze independently, from one position to another, without human intervention. There is a myriad of autonomous industrial mobile robot applications, including the transportation of goods and parts, domestic cleaning, indoor security surveillance, airport baggage couriering, and a plethora of other applications to traverse dangerous locations. This paper proposes a pathfinding mobile robot in a virtual maze based on a combination of a simplified left-hand algorithm and a line-following control algorithm. The mobile robot works in any maze to determine a route from the initial starting point to the end-point. The approach outlined in this paper uses a left-hand algorithm to solve the maze problem and a line-follower control algorithm to enable the robot to move in a straight line through the virtual maze. The algorithm used is less complicated and prevents the robot from falling into infinity loops compared to the traditional wall-follower algorithm.

Do Different Types of Households Use Outsourced Domestic Cleaning Services for Different Reasons? An Explorative Study in South Africa

In recent years, many households have shifted from employing a full-time or part-time domestic worker to using an outsourced domestic cleaning services company that specialises in professional household cleaning services. Few studies have focused on outsourced domestic cleaning services from clients’ perspectives. While there is limited research on the topic, a possible reason for the increase in outsourced domestic cleaning services might be that the domestic labour needs of the middle-class are changing. The decline in the stigma of voluntary childlessness and better educational and career opportunities for women have impacted household compositions. There has been a rise in one-person households and couples without children. These changes affect how domestic work is approached. Some women continue to perform domestic labour themselves, while others employ domestic workers or use outsourced domestic cleaning services. Against this background, this study sought to establish how changes in household compositions are linked to peoples’ preferences to use outsourced domestic cleaning services to take care of their domestic cleaning needs rather than employing a domestic worker on a full-time or part-time basis. This study draws on 18 qualitative interviews with clients of domestic cleaning services and shows that people who live alone, as a childless couple or in an empty-nest household, use outsourced domestic cleaning services for their convenience, efficiency, and flexibility. Couples with children tend to rely on personal help when it comes to care work but outsource less emotional domestic duties to domestic cleaning service companies. This study contributes to new insights by showing that domestic cleaning services are used by households who can afford and require flexible cleaning services offered by outsourced domestic cleaning services.

‘The Food Package Makes My Hands Dirty Now’: Exploring Domestic Cleaning Practices During the Pandemic

This article examines how domestic cleaning practices were transformed during the pandemic and how they redefined everyday life. Based on a perspective of actor-network theory, we take the food package as an actant and follow it in domestic space through its interactions with other actants. To get a deeper understanding of these interactions, we conducted an ethnographic study focusing on the food package. Our findings reveal that the new cleaning rituals emerging in this context are shaped by metaphors, which are connected to a broader network of cleaning culture based on particular traditions and beliefs.

Perfil demográfico e clínico de casos ocupacionais de sensibilização a metilisotiazolinona e Kathon CG: estudo seccional

Abstract Introduction: methylisothiazolinone alone or associated with methylchloroisothiazolinone (Kathon CG) is a preservative related to occupational allergic contact dermatitis. Objectives: to evaluate the demographic and clinical profile of occupational cases of sensitization to isothiazolinones in the city of Rio de Janeiro and to describe the presence of these preservatives in national paints. Methods: cross-sectional study based on information from medical records of workers who underwent patch testing between 2013-2017. The prevalence of clinical, demographic and occupational characteristics was described and an unadjusted model was used to investigate the association between variables. We sought the presence and concentration of isothiazolinones in the chemical composition sheets of national paints. Results: among the 768 workers submitted to the tests, 68 had occupational dermatosis with a positive result for sensitization to methylisothiazolinone/Kathon CG. The most affected occupations were those related to domestic activities and cleaning. There was a greater likelihood of sensitization to isothiazolinones in women and in those with involvement of the hands and legs. Among the 61 paints evaluated, 26 had some isothiazolinone, with methylchloroisothiazolinone being the most common. Conclusions: sensitization to isothiazolinones can impact workers’ health and demands greater vigilance on cleaning materials and cosmetics, as well as discussing the composition regulation of the paints sold in Brazil.

Paid domestic work and outsourcing in South Africa: Clients’ views on trust, control and power relations

Outsourced domestic cleaning service suppliers reconfigure the bipartite employment relationship between employers and domestic workers into a tripartite one between clients (former employers of domestic workers), the management or franchise owners, and domestic employees. While this transformation is attractive to some, outsourcing domestic work involves more than the outsourcing of physical tasks of household cleaning. It also involves the outsourcing of the employment relationship where trust, control and power relations are passed on to the management of the domestic cleaning service suppliers. By taking trust, control and power relations as being reconfigured through outsourcing, this article debates why such reconfiguring might not be convenient for some. By doing this, trust, control and power are conceptualised and how it is perpetuated in a bipartite and tripartite domestic employment relationship. By drawing on 16 in-depth interviews with former clients of a domestic cleaning service supplier in South Africa, this article illustrates that perhaps outsourced domestic services are not an appropriate solution to everyone’s domestic cleaning needs and that some clients expect a particular relationship that is not achieved through outsourcing.

Enteric parasites and socio-epidemiological variables in an academic community

Studies linking human health to environmental conditions are essential since parasitic diseases are connected to environmental and sanitary aspects. This study identified the prevalence of enteric parasites in an academic community in the municipality of Santo Antônio de Jesus, Bahia, Brazil. The purpose was to determine the existence, or not, of links between infections and socio-epidemiological variables, such as personal hygiene habits, the presence of sewage systems and the environment. Participants answered a questionnaire and received universal collectors for fecal samples. Spontaneous sedimentation methods and Rugai were used for diagnosis. One hundred twenty-one samples were analyzed, in which a 38.8% parasite prevalence was detected as well as a 61.7% rate of monoparasitism, as well as a predominance of protozoa Endolimax nana (78.7%) and Giardia duodenalis (21.3%). Among parasitized individuals, 97.9% lived in the Recôncavo Baiano region. The following statistical significance stands out in the findings, with p<0.05: individuals who had already bathed in the local river were more likely to be parasitized than those who had not (p = 0.034) and individuals who washed their hands more frequently before meals proved to be less prone to intestinal parasitic infections (p = 0.018). Results evidenced the presence of enteric parasites in a number of participants in spite of their being university students. The socio-epidemiological variables analyzed brought to light characteristics that favor the establishment of the epidemiological infection triad, such as improper packaging of household waste on disposal and no records of regular domestic water tank cleaning. KEY WORDS: Enteric parasites; environment; diagnosis; health education.

Sensing the (in)visible: domestic cleaning and cleaners on Mumsnet Talk

ABSTRACT Based on a thematic analysis of 7,569 posts on the online parenting forum Mumsnet Talk, in this article we examine how domestic cleaning—one of the most invisible aspects of reproductive labour—and the people who perform it are made visible. We conceptualize Mumsnet discussions as a “visibility sensor:” a technological and affective space that captures, analyses and relays information and feelings in ways that contribute to visibilizing cleaning labour and sensitizing its users to recognize the women they employ to clean their homes. At the same time, our analysis highlights the limitations of this sensor: how the visibility Mumsnet discussions afford to cleaning and cleaners tends to reinscribe its meanings within a gendered and individualized logic. This mediated visibility mostly fails to expose the systemic structures that produce and sustain the invisibility of cleaning and cleaners, and does little to sensitize participants to the ways in which their own lives are shaped by patriarchy. The article contributes to the growing feminist scholarship examining how gender and class come into public visibility through social media platforms and the “digital mamaspehere,” and the implications of this visibility for the configuration and reconfiguration of power relations.

Design of a train cleaning robot for the train carriage interior

This paper describes the design of a robot platform that can collect and disposing waste in passenger trains. It covers an analysis of the key design considerations for success in operating in a train environment, as well as considerations in manipulating waste in an often-confined space. The design constraints are analyzed for their importance in the successful development of a train cleaning robot. The analysis informs the development of three robot designs. These designs are assessed in their appropriateness for development against a baseline design that uses readily available parts. Among the three designs developed, one uses a vacuum powered arm similar to the type utilized in manufacturing plants, one is based on the dustpan and brush used in domestic cleaning, and one is based on a conveyor belt. These designs are assigned a percentage suitability for implementation in the automated train carriage cleaning system. Using the key values and the requirements the design should fulfil, a systematic investigation is undertaken. This investigation finds the conveyor belt design most appropriate for application due to the sustainable design and effective cleaning that can be undertaken without additional tools.

Polymeric surfactants as alternative to improve waterflooding oil recovery efficiency

Chemical formulations, including surfactants, polymers, alkalis, or their combinations, are widely used in different oil recovery processes to improve water injection performance. However, based on challenging profit margins in most mature waterfloods in Colombia and overseas, it is necessary to explore alternatives that could offer better performance and greater operational flexibility than the conventional technologies used for enhanced oil recovery (EOR) processes.
 Polymeric surfactants are compounds widely used in the manufacture of domestic and industrial cleaning, pharmaceutical, cosmetic, and food products. These compounds represent an interesting alternative as they can simultaneously increase the viscosity in water solution and reduce the interfacial tension (IFT) in the water/oil system, which would increase the efficiency of EOR processes.
 This article shows a methodological evaluation through laboratory studies, numerical reservoir simulation, and conceptual engineering design to apply polymeric surfactants (Block Copolymer Polymeric Surfactants or BCPS) as additives to improve efficiency in water injection processes. Block copolymer type products of ethylene oxide (EO) - propylene oxide (PO) - ethylene oxide (EO) in aqueous solution were studied to determine their rheological and surfactant behavior under the operating conditions of a Colombian field.
 In the conditions studied, these products allow to reduce the interfacial tension up to 2x10-1 mN/m values and also cause a shear-thinning rheological behavior following the power law at very low shear rates (0.1 s-1– 1 s-1), which corresponds to an increase up to four orders of magnitude in the capillary number (Nc). The IFT and the viscosity reached are maintained in wide ranges of salinity, BCPS concentration, and shear rates, making it a robust performance formulation.
 In a model porous medium, BCPS tested have moderate adsorption, less than conventional surfactants but higher than HPAM polymers, in any way allowing a favorable wettability condition. Additionally, it was observed that they offer a resistance factor up to 16 times, causing greater displacement efficiency than water injection, allowing better sweeping in low permeability areas without injectivity restrictions.
 Numerical simulation shows that it is possible to reach incremental production up to 238,5 TBO by injecting a continuous slug of 0.15 pore volumes of BCPS and HPAM, each with 2,000 ppm concentration and a flow rate of 2,500 BPD. As BCPS are simple handling and dilution products, these could be injected directly in water injection flow using a high precision dosing pump with high pressure and flow rate operational variables.

A qualitative study of community perspectives surrounding cleaning practices in the context of Zika prevention in El Salvador: implications for community-based Aedes aegypti control

BackgroundIn El Salvador, Aedes aegypti mosquitoes transmitting Zika and other arboviruses use water storage containers as important oviposition sites. Promotion of water storage container cleaning is a key element of prevention programs. We explored community perceptions surrounding cleaning practices among pregnant women, male partners of pregnant women, and women likely to become pregnant.MethodsResearchers conducted 11 focus groups and 12 in-depth interviews which included individual elicitations of Zika prevention measures practiced in the community. Focus group participants rated 18 images depicting Zika-related behaviors according to effectiveness and feasibility in the community context, discussed influencing determinants, voted on community intentions to perform prevention behaviors, and performed washbasin cleaning simulations. In-depth interviews with male partners of pregnant women used projective techniques with images to explore their perceptions on a subset of Zika prevention behaviors.ResultsGeneral cleaning of the home, to ensure a healthy environment, was a strong community norm. In this context, participants gave water storage container cleaning a high rating, for both its effectiveness and feasibility. Participants were convinced that they cleaned their water storage containers effectively against Zika, but their actual skills were inadequate to destroy Aedes aegypti eggs. A further constraint was the schedule of water availability. Even during pregnancy, male partners rarely cleaned water storage containers because water became available in homes when they were at work. Furthermore, prevailing gender norms did not foster male participation in domestic cleaning activities. Despite these factors, many men were willing to provide substantial support with cleaning when their partners were pregnant, in order to protect their family.ConclusionsBehavior change programs for the prevention of Zika and other arboviruses need to improve community members’ mosquito egg destruction skills rather than perpetuate the promotion of non-specific cleaning in and around the home as effective. Egg elimination must be clearly identified as the objective of water storage container maintenance and programs should highlight the effective techniques to achieve this goal. In addition, programs must build the skills of family members who support pregnant women to maintain the frequency of effective egg destruction in all water storage containers of the home.

Domestic exposure to irritant cleaning agents and asthma in women

An adverse role of frequent domestic use of cleaning agents, especially in spray form, on asthma has been reported. However, sparse studies have investigated respiratory health effects of chronic domestic exposure to irritant cleaning agents. This study aims to investigate associations between weekly use of irritant domestic cleaning products and current allergic and non-allergic asthma in a large cohort of elderly women.We used data from the Asthma-E3N nested case-control study on asthma (n = 19,404 women, response rate: 91%, 2011), in which participants completed standardized questionnaires on asthma and on the use of domestic cleaning products including irritants (bleach, ammonia, solvents and acids). Allergic multimorbidity in asthma was assessed from allergic-related medications recorded in drug refunds database. The association between use of irritants and current asthma was estimated by logistic regression (current vs. never asthma) and multinomial logistic regression (never asthma, non-allergic asthma, allergic asthma) adjusted on age, smoking status and body mass index (BMI).In the 12,758 women included in the analysis (mean age: 70 years, current smokers: 4%, BMI ≥ 25 kg/m2: 32%, low education: 11%, current asthma: 23%), 47% reported weekly use of at least one irritant cleaning product at home. Weekly use of irritant products was associated with a higher risk of current asthma (adjusted Odds-Ratio: 1.17, 1.07–1.27). A statistically significant dose–response association was reported (p trend < 0.0001), with both the number of irritant products used weekly (1 irritant: 1.12, 1.02–1.23; 2 irritants: 1.21, 1.05–1.39; 3 irritants or more: 2.08, 1.57–2.75) and the frequency of use (1–3 days/week: 1.12, 1.02–1.23; 4–7 days/week: 1.41,1.22–1.64). A dose–response association was observed with the frequency of products used (p trend < 0.05), for both non-allergic (4–7 days/week: 1.27, 1.02–1.57) and allergic asthma (1.52, 1.27–1.82).In conclusion, weekly use of common cleaning irritants was associated with an increased risk of current asthma, whatever the allergic status.
