description: Until today, several low-income communities living in formal and informal settlements in South Africa don’t have access to municipal waste collection, leaving the residents behind with a huge amount of waste generated day by day. Parts of the solid household waste (SHW) accumulated are absorbent hygiene products (AHP). They are designed to absorb human fluids over various stages of life. Improperly disposed AHPs form a serious risk on health and environment. In this study, the amount of AHP waste generated and the geographical distribution of illegal dumpsites in two informal settlements (Johanna Road & Blackburn Village) was investigated. First, a Participatory Mapping was organized with residents from the communities to point out estimated dumpsites and to plan the next step. A Transect walk concluded the localization of illegal disposal sites. Next, a solid household waste characterization was conducted in both settlements. The study sampled 151 households in Johanna Road and 82 households in Blackburn Village. The SHW was quantified in 12 categories of which one was AHP waste. The results showed that the average generation of solid household waste in Johanna Road was 2.47 kg/household/day. The largest part were plastics (33.2%), followed by food waste / organics (29.1%) and AHP waste (21.2%). In Blackburn, the average SHW generation rate was 0.85 kg/household/day of which 43.6% was AHP waste. The bin capacity needed to collect all AHP waste was estimated to be 4060 litres/week in Johanna Road and 3820 litres/week in Blackburn, respectively.

description: Over one third of the global population is not connected to a sewage system. Many low- and middle-income economy countries do not rely on infrastructure for centralised wastewater solutions. This results in blackwater being untreated, which leads to an increased public and environmental risk. As a solution in these often densely populated urban areas, cost-effective off-grid and decentralised systems seem to be an auspicious option. Most of these solutions include a dewatering step. However, current dewatering technologies (for example drying beds) are based on a high footprint and are not a sustainable solution for dense urban areas. A dewatering screw press offers a promising alternative that has the potential to solve these problems. It consists of a revolving screw that squeezes out the liquid in the blackwater through a sieve by compression. Hereby, the solid and liquid content is separated, and the blackwater is set up for further treatment. Screw presses already exist to treat wastewater on a large scale for entire cities, but not on a small scale. The goal of this thesis was to build a simple, robust and cost-effective screw press for up to 50 people, by reaching a high solid content in the sludge cake. The method to build such a system is by the means of agile product development. The idea behind this process is to work in many iterations with a large amount of testing. By this, it is possible to reach high adaptability to changes, and to minimise risks through early and numerous testing.
This project started by building a minimum viable product, which puts the focus on the core mechanism of the screw press. Upon that, further prototypes are built and continuously improved by an iterative process including many trials. The tests are carried out with real blackwater in order to obtain as realistic a scenario as possible. The turbidity and the solid content are measured to assess the performance of the screw press. The final prototype is manufactured mostly by using metal sheet parts made of stainless steel. This made it possible to use simple and cost-effective manufacturing techniques. Other parts were produced by additive manufacturing, which allowed more complex designs like that of the screw to be realised at low costs. The results showed that by such a machine a high solid content of up to 30.3 wt% could be achieved. This is comparable to commercial screw presses.
To summarise, it was possible to build a simple, robust and cost-effective screw press on a small scale. The system worked fine and was able to perform its task.

“I have just accepted it”: Hierarchies of Power and Healthcare Waste Management Practices in Blantyre, Malawi
Creators: name: Song, Sarah
Publisher: name: ETH Zurich
Year: 2023

description: Medical waste management practices in the Majority World have gained traction in the academic sphere, catapulted by studies detailing the knowledge, attitudes, and practices of healthcare workers in resource-constrained systems. Yet, by restricting the analytical space to surface determinants such as ostensible staff conduct, and material factors involved in this conduct, broader socio-cultural structures associated with waste management practices have largely evaded scholarly attention. This article thus draws on qualitative fieldwork to investigate these structural phenomena by way of semistructured interviews. The purpose of this work is to unearth the power hierarchies that inform operational inadequacies and structural mechanics responsible for daily operation at Queen Elizabeth Central Hospital in Blantyre, Malawi. Findings suggest that embedded gender and power dynamics, complemented by chronic resource and labour shortages, jointly determine and complicate best practices in healthcare waste management. Notably, safety hazards posed by sharps mismanagement and respiratory ailments were two main consequences derived from these findings. Proposing recommendations for mitigation efforts would benefit from broadening the scope of this research. By opening channels of academic dialogue into Southern waste management contexts, we hope to build a more inclusive and comprehensive waste management discourse.

Improving Market Wash Stations Through Creative and Contextual Design in Durban, South Africa
Creators: name: Mechael, Celine Nabil Me
Publisher: name: ETH Zurich
Year: 2022

description: Safe water, sanitation and hygiene practices are essential in mitigating the spread of infectious diseases, yet access to adequate handwashing infrastructure remains poor for many in the Global South. This disparity was particularly felt by informal workers in South Africa during the COVID-19 pandemic, as informal workspaces generally lack basic access to clean water and hygiene facilities. Although handwashing is an effective way to stop the spread of COVID-19, a gap in the literature on locally procurable low-cost solutions appropriate for informal contexts still exists. In spite of this, the NGO Asiye eTafuleni took the initiative to develop handwashing stations made of low-cost and recycled components and deployed them across the nine informal markets of Durban's Warwick Junction between 2020-2022. However, their "street corner" solution proved inadequate in the face of the highly dynamic setting of these markets, showing low durability and being subjected to use cases that rapidly depleted the station from its water. Moreover, since hand contact is required to operate this station, its effectiveness as a hygiene tool may be compromised in this high friction environment. 

The purpose of this bachelor thesis is to contribute to bridging South Africa’s hygiene inequality by iterating on AeT’s street corner station for more long-term and contextually appropriate solutions at Durban’s Warwick Junction. Accordingly, a minimum viable prototype of a foot-actuated pump dispenser composed of low-cost and recycled components was produced. The setup was then tested by at least 23 users at ETH Zürich. An initial assessment of the station’s performance and feedback from the test group revealed some aspects that require further development for increased durability and an ergonomically improved design, particularly within the dispensing mechanism. Although this prototype would not be ready for deployment at Warwick Junction, it may prove itself a valuable lead for future iterations, especially since an estimated cost reduction of up to 75% could be achieved with this initial prototype in comparison to existing solutions of similar function. The results demonstrate that, with further development, long-term, locally procurable, and low-cost solutions for traders in South African street markets may be feasible, and the design warrants further investigation to help bridge the literature gap on WASH solutions befitting informal contexts.

description: Genus Acanthomegabunus Tsurusaki, Tchemeris & Logunov, 2000
Type species. Acanthomegabunus sibiricus Tsurusaki, Tchemeris & Logunov 2000; designated by monotypy.
Diagnosis. Most similar to Megabunus Meade 1855 from western Europe (Martens 1978), but distinguished by the following characters: 1) absence of long ventral spines on the palpal trochanter (Tsurusaki et al. 2000: fig. 3B–C); 2) presence of a dorsal row of conspicuous spines on palpal patellae (Tsurusaki et al. 2000: fig. 3B–C; Figs. 1–2, 4–5, 10–11); and 3) all legs with five to six longitudinal rows of erect spines (Tsurusaki et al. 2000: fig. 2A–C; Figs 1–5).
Description. Medium-sized opilionids, with soft or, rarely, rigid integument, body smooth except for a transverse row of several minute tubercles on each abdominal tergite and a few scattered teeth on the cephalothorax. Ocular tubercle huge, with numerous long spines (Figs 1–5).
Chelicera normal, without a ventral tooth on its basal joint; movable finger without apophysis (Figs 6–7). Supracheliceral lamellae not developed, invisible from above. Scent gland pores visible from above (Figs 1–3).
Palpi (Figs 1–5, 10–11) with distomesal apophyses on patellae and tibiae; femora distomesally with a knoblike process bearing several bristles, femora distomesally with a hump, ectal surface of femur with a group of 4–6 pores (presumably of glandular function) near the basal joint; male tarsi with a ventromesal row of denticles (unarmed in females A. sibiricus, female unknown in A. altaicus sp. nov.); femora to tibiae dorsolaterally and ventrally with three rows of conspicuous spines; palpal claw untoothed.
Legs relatively short; trochanter to metatarsus with one row (metatarsi) or five longitudinal rows (femur to tibiae) of erect spines. Penis dorso-ventrally flattened, a bundle of muscles occupying basal one-third to two-thirds length of corpus (Figs. 12, 14).
Composition. Two species: Acanthomegabunus sibiricus and A. altaicus sp. nov., both are known from the mountains of South Siberia, Russia.

description: Genus Arcotheres Manning, 1993
Remarks. The taxonomy of the Indo-West Pacific Pinnotheridae is still unstable, especially with regards to many of the species described in the 1800s and early 1900s. The species described in this era were often diagnosed only very briefly and key characters are omitted or not figured accurately (if at all). The identity of many species described by Bürger (1895) were partially resolved by the redescription of the extant types by Ahyong & Ng (2007) but as these authors noted, the material is often in a poor condition and host data is not always available.
For many years, the third author has been actively revising the Indo-West Pacific pinnotherids, often with S.T. Ahyong (Australian Museum) (e.g., Ahyong & Ng 2007; Ahyong 2018; Ng & Biju Kumar 2015; Ng et al. 2017; Ng 2018; Ng & Corbari 2019), and has obtained a good series of several poorly known species from Southeast Asia, notably species associated with clams of the families Arcidae and Veneridae. Most belong to the genus Arcotheres Manning, 1993. One group of species associated with arcids is characterised by the possession of a relatively more chitinised and more calcified carapace and pereopods, as well as relatively shorter ambulatory legs. This group includes species such as A. palaensis (Bürger, 1895) (type species of the genus) and A. arcophilus (Bürger, 1895). The species of a second group are associated with venerids, and include A. exiguus (Bürger, 1895) and A. rotundatus; those species have poorly chitinised and soft carapaces and relatively long ambulatory legs. The resolution of the identities of the Fijian Arcotheres is possible here because of many of the species in these groups have been revised and will be published in a major forthcoming study. The unpublished data from this study will nevertheless be used when required so the taxonomic problems associated with the Fijian species can be solved.

description: Asiye eTafuleni, a South African non-profit organization, has launched a program giving workers and customers at a popular market conglomeration in Durban, South Africa, access to public urinals. Since these urinals are not connected to a sewage system, they instead require a means to regularly empty the on-site urine storage and to transport the urine off to a centralized storage location.
The objective of this semester project was to find a solution to this problem by designing, building, and testing a urine collection trolley. If successful, the design was then to be replicated and deployed in Durban as part of the urinal program.
In order that Asiye eTafuleni could continue using their old cart, it was decided to use a barrow similar to the ones commonly found in South Africa as a basis for the prototype. Other key components included a 126-liter water tank, a cover, a pump, and a storage solution for the pump’s hoses in the form of two plastic pipes. The entirety of the accessories could be removed from and reattached to the trolley with the help of two ratchet straps.
The system was tested the same way it would be used in its real working environment in Durban, except that the urine was exchanged for water. In other words, the testing stage consisted of repeatedly pumping water from a canister into the cart’s tank, and then pulling the cart through the streets for 1.85 kilometers while loaded with 110 liters of water. Although a few design flaws manifested themselves over the course of the testing process, most of those are easy to fix and all in all both tests proved to be well feasible for the prototype.
As a result, the project can be viewed as a success, having produced a urine collection trolley capable of efficiently emptying the urinal drums and transporting the urine to a final storage location.
Humanitarian Sanitation Solution: Design and Validation of a Thermal Disinfection Unit for Wastewater using Biogas for Humanitarian Crisis Situations
Creators: name: Jäggi, Julia
Publisher: name: ETH Zurich
Year: 2023

description: Access to safely managed sanitation is a globally unsolved challenge, especially in humanitarian settings. Big treatment facilities are not available, and many treatment technologies need a lot of fuel or electricity for them to run: resources that are often absent in crisis situations. The release of untreated wastewater in the environment or the lack of access to a sanitation system leads to the spread of pathogens. Already vulnerable groups are exposed to the spread of diseases like diarrhoea and cholera which leads to increased numbers of deaths.
ETH Zürich, Sistema.bio, and Opero try to tackle this problem with a new wastewater treat- ment unit. The goal is to bring a modular, rapidly deployable human waste treatment system to market for the use in humanitarian settings.
A key feature of the system is its operation nearly independent of additional energy input. Biogas is produced using a biogas digester and pit latrine sludge, the very sludge that will be treated in the second step. The anaerobic digester, a product called DungBeetle, is already globally in use with animal waste. The adaptation for use with human waste is on the path to success. Combustion of the biogas is used to thermally disinfect the digester effluent.
The focus of this thesis is to design a second, improved prototype and validate that the thermal disinfection kills the pathogens and leads to wastewater that can be safely released into the environment. The aim is to treat 700 liters of effluent per day. The promising results illustrated in this thesis could lead to a solution for adequate wastewater treatment in humanitarian crisis situations.

description: The Kumasi Wastewater Treatment Plant is a recently constructed faecal sludge treatment plant located in Kumasi, Ghana. It is designed to treat 1000 m3/d of faecal sludge. It is the first plant employing the Modified Bardenpho process for faecal sludge. A mixed-method approach was used to assess the suitability of the Bardenpho process for faecal sludge treatment. The characteristics of the received faecal sludge were examined, as well as the treatment performance in terms of removal efficiency and compliance with local effluent quality guidelines. Measurements were carried out to assess process functioning, and interviews were conducted with employees to investigate the impact of the following aspects on the performance: a) design and layout, b) operations and maintenance, c) quality control and d) data management. A high variability in quantity and quality was observed (median ± standard deviation: 917 ± 146.5 m3/d; 4208 ± 5007 mg/L COD; 628 ± 468 mg/L TN; 40 ± 42.8 mg/L TP). Critical parameters in terms of median compliance with the Ghana EPA effluent discharge guidelines were NH4+-N (10.7 mg/L), NO3--N (122 mg/L), TP (11.3 mg/L) and E. coli (>105 cfu/100mL). The median removal efficiencies were 95% for COD, 99% for TSS, 96% for NH4+-N, 73% for TN and 71% for TP. The Bardenpho process was not taking place as designed with no actual anaerobic zone, likely caused by a high return activated sludge flow. Some of the installed technologies were not performing as anticipated and poorly planned infrastructure resulted in disturbances. The dependence on the import of high-cost materials with insufficient supply chains was found to lead to frequent shortages of the required materials for operations, maintenance and quality control, causing inconsistent operation and an impaired treatment. A lack of training and technical knowledge was identified. Standard laboratory practices are not always followed, resulting in inaccurate measurements. Data recording and storage systems were found to be insufficiently organised. Collected data is not readily available for analysis and decision making. The Bardenpho process did not seem to provide the required flexibility under highly variable conditions and was found to be not suited for faecal sludge treatment, especially in a resource-limited setting. Further research is needed to identify strategies for a sustainable and effective operation of the plant and to investigate whether biological phosphorus removal is feasible.

description: Introduction: To improve outcomes of current shunt treatments
for hydrocephalus, a better understanding of cerebrospinal fluid
(CSF) physiology is needed. Because malfunctions arise from posture
changes, measurements of intracranial pressure (ICP) fluctuations and
their relation to blood pressure during these changes shall provide
valuable insights.
Methods: ICP and femoral blood pressure (FBP) of five healthy rats
were continuously measured in a chronic trial via radio telemetry
implants and sampled at 1 kHz. While being awake and moving freely
in an observation box, the rats were monitored with a camera system
at 30 fps. Means and correlation coefficients of ICP and FBP during ten
natural rear ups per rat were analyzed with t-tests.
Results: Rear ups lasted on average 2.13 s. During these, FBP assessed
as mean±SD (106.5 ± 17.4 mmHg) and ICP (1.4 ± 3.8 mmHg) were
on average lower than FBP (118.9 ± 11.9 mmHg) and ICP (1.6 ± 4.0
mmHg) before rear ups. Changes of FBP were significant (p < 0.05) in
all rats, whereas changes in ICP were significant (p < 0.05) in only two
rats. In one of these two rats, correlation coefficients were significant
(p < 0.01). ICP and FBP during these rear ups were on average moderately
positively correlated (r = 0.24).
Conclusion: Concurrent measurements of CSF related pressures in
rats are inherently challenging due to the limited space for sensor implants and rapid movements leading to strong artefacts. However,
statistically significant CSF dynamics due to posture changes could
be observed using high resolution pressure and video recordings.
