Development of a Low-Cost Dual-Wavelength Black Carbon Monitor
Black carbon (BC) is a critical component of atmospheric aerosols, with significant implications for climate change, air quality, and public health. Affordable monitoring of black carbon is essential for advancing research and policy in under-monitored settings. Currently, commercial black carbon monitors are expensive, limiting their accessibility and deployment. Open-source black carbon monitors offer a promising alternative, providing a low-cost and customizable solution. However, existing open-source black carbon monitors typically measure light absorption at only a single wavelength, which restricts their ability to differentiate between BC from various sources. A previous master’s student conducted an extensive literature review on the components required to develop a low-cost black carbon monitor and conducted a preliminary cost analysis. This proposal seeks to build on that foundational research by developing a low-cost, dual-wavelength black carbon monitor in the laboratory.

Using BSFL frass as a growth substrate for mushroom production
Black soldier fly larvae (BSFL) are increasingly used for organic waste recycling and animal feed production. They can be used on a broad variety of organic waste products like market or food waste or faeces and manure. BSFL treatment produces two products, larvae which can be used as animal feed and frass which consists of insect excrements and indigestible organic residues. Frass is still rich in nitrogen and carbohydrates and is being composted before being used as a soil amendment. However; the frass might also be usable as a substrate for growing mushrooms and therefore used to create more value for the BSFL facility. The goal of this work is to test if BSFL frass is a good substrate for growing mushrooms or can help as an additive to another substrate increase mushroom yields. This work will take place in cooperation with EAWAG which is a leading institute working on BSFL waste treatment.

Pre-treatment of Black Soldier Fly substrate with white rot fungi
Black soldier fly larvae (BSFL), scientifically known as Hermetia illucens, have emerged as a promising solution for organic waste recycling and sustainable animal feed production. These remarkable insects possess the ability to convert a wide range of organic materials into valuable biomass, rich in proteins and lipids. However, their efficiency is somewhat limited when it comes to processing complex carbohydrates, particularly those found in lignocellulosic waste. In contrast to BSFL, white-rot fungi (WRF) possess a unique set of ligninolytic enzymes that enable them to degrade lignin, hemicellulose, and cellulose effectively. The goal of this research is to explore how pretreatment of lignocellulosic waste using white-rot fungi can increase the availability of nutrients for BSFL in the pretreated substrates.

Design, Construction, and Testing of an Anaerobic Baffled Reactor
Dark fermentation involves the hydrolysis and acidogenesis of carbon-rich substrates to produce hydrogen (energy) as the main product and volatile fatty acids (acetic acid, butyric acid and propionic acid) as byproducts. Reactor configuration is an important parameter that influences the production rate and yield. The Anaerobic Baffled Reactor (ABR) is a simple design with minimal costs and fosters the separation of different phases of the anaerobic process thus enhancing the resilience of the bacterial population to fluctuations of the organic loading rate. Additionally, the reactor can be designed in household modular settings and built underground to retain heat. The ABR has been evaluated for anaerobic digestion of high-strength wastewater (Sayedin et al., 2018, 2019) and to a lesser extent, for the anaerobic digestion of solid waste such as food waste. There are only a few studies on the use of ABR for dark fermentation (e.g. Jürgensen et al., 2015). Therefore, it is important to understand how ABR configuration can be modified for dark fermentation, particularly for processing solid waste.

Developing citizen science methods to measure biogas usage in a Swiss carbon offset project in Malawi
Article 6 of the Paris Agreement promotes international cooperation, allowing high-income countries to meet carbon reduction goals affordably by funding projects in lower-income countries and claiming the resulting offsets. Under its CO₂ Act, Switzerland, through the KliK Foundation, aims to offset 40 million tonnes of CO₂ by 2030—10% of its national emissions—over half of which will occur abroad. One planned collaboration with Malawi involves distributing 10,000 household biogas digesters to dairy farmers2, expected to mitigate 436,000 tonnes of CO₂e. These digesters convert organic waste, primarily animal dung, into methane-rich biogas, replacing wood as a cooking fuel and reducing emissions from deforestation and biomass burning. Dr. Natalie Boyd Williams, a postdoctoral research fellow in the Global Health Engineering group at ETH Zurich, is seeking a student for an exciting Masters thesis project. Dr. Boyd Williams' fellowship focuses on assessing the efficacy of the Malawi biogas project's carbon savings, which hinge on households effectively and consistently using biogas as their primary cooking fuel over firewood. Accurately estimating biogas usage is critical to understanding the project's impact. Traditional methods, such as surveys, often rely on users recalling their cooking habits over long periods, introducing significant uncertainty and error. This thesis aims to address these limitations by developing and trialing a citizen science biogas usage estimation methodology that complements surveys, improving the accuracy of usage data.

Life Cycle Analysis of household biogas digesters used in international carbon trading agreements
Article 6 of the Paris Agreement encourages international cooperation and allows high-income, high-polluting countries to meet their carbon reduction commitments affordably by funding carbon reducing activities in lower-income countries, claiming the carbon reductions for themselves1. Specifically, Switzerland, under its CO₂ Act and through the The Swiss Foundation for Climate Protection and Carbon Offset (KliK Foundation) aims to offset about 40 million tonnes of CO₂ by 2030—10% of its national emissions–with over half of these offsets occurring abroad. One upcoming collaboration is with Malawi, which involves distributing 10,000 household biogas digesters to dairy farmers2. This project is expected to mitigate approximately 436,000 tons of carbon dioxide equivalent (CO2e) annually. The primary function of these digesters is to convert organic wastes, predominantly animal dung, into a methane-rich gas. Biogas can be used as a cooking fuel, replacing wood, which is often sourced from local forests, thus reducing carbon emissions from deforestation as well as from the burning of biomass. The model being installed is the Sistema.bio biogas digester, a plastic bag digester with other components such as valves, pipes and stoves for cooking. These biogas parts are sourced globally—though the exact origins are uncertain—and then assembled in another country. They are shipped to Malawi as ready-to-assemble kits. Biogas has been used as a carbon offset technology for years, but the carbon footprint of the digesters are overlooked in carbon offset calculations. Sistema.bio, as well as other manufacturers, are implementing biogas projects in many countries worldwide using carbon financing, making it crucial to understand the carbon footprint of the installations to accurately estimate their carbon offset potential. Several life cycle assessment (LCA) studies of similar biogas digesters suggest that biogas plants need to operate for up to two years to offset their construction emissions3. This has significant implications for global carbon offsetting and trading and would mean that projects might not be offsetting as much carbon as calculated, and buyer countries, such as Switzerland, should do more to reduce their carbon footprints. It is currently unknown what the carbon footprint of Sistema.bio digesters are as well as other competitors with similar business models and how the carbon footprint compares to more traditional cement and brick digesters that can be built in the country of implementation. It is thus also unknown how the digester footprint might affect carbon reduction estimations of the projects.
