Anastasija Vasiljev interning with the urine drying project

My name is Anastasija Vasiljev. I am a Serbian girl finishing my environmental engineering bachelor’s at South-Eastern University of Applied Sciences in Finland. I only have an internship and a thesis left to complete, before I am fully done with my program. At SLU, I will be working as a part of the urine drying research team. My responsibilities are to aid in figuring out how to minimize the nitrogen losses during urine drying process, performing experiments to determine the most efficient media for nitrogen capture. I will stay and be a part of the team until the end of January next year!

Removal of Selected Pharmaceuticals and Personal Products in Wastewater Treatment Plant in Jordan

In collaboration Othman Masahgbeh (RSS- Jordan) and other researchers in Lincoln University, Sahar Dalahmeh from our group has published an article Removal of Selected Pharmaceuticals and Personal Products in Wastewater Treatment Plant in Jordan in the journal, Water.

The authors concluded that the highest average concentrations of personal care products (PPCPs) which were detected in treated wastewater were for carbamazepine, sulfamethoxazole, caffeine, and cotinine. This study clearly showed that incomplete removal and/or degradation of PPCPs takes place in As-Samra WWTP, the biggest and most advances WWTP in the country. Less effort has been made to minimize the levels of PPCPs contaminants at their sources, especially at home, pharmacies, and hospitals. Therefore, there is a need in Jordan to raise public awareness about the impact of these contaminants on water and the food cycle. This awareness will help the local authorities to implement any future policies that cover pharmaceutical waste management and handling at home, pharmacies, and hospitals.

Chea Eliyan joins Kretsloppsteknik as a PhD student

I am Chea Eliyan, and I recently joined the Environmental Engineering Research Group of the Department of Energy and Technology, SLU, in a sandwich mode Ph.D. program. As part of this program, I will spend half the time here at SLU and another 50% time at my home country, Cambodia at the Royal University of Phnom Penh (RUPP). The SIDA-RUPP bilateral program fully supports this study as well as RUPP’s research capacity development.

Tristan Martin, PhD Student from INRA at Kretsloppsteknik

My name is Tristan Martin and I’m a PhD student from France. I’m working at the French National institute for agricultural research on the agronomic valorization of urine in France and the associated environmental impacts of this valorization. My work in France consists mainly in doing agronomical experiments with different urine based fertilizers to compare their agronomical efficiencies (yields, NH3 volatilization, N2O emissions …). I will be there in Uppsala for 3 month to work on the second part of my PhD which aims to evaluate the impacts of the whole valorization chains (treatment, transport …) using life cycle assessment methodology.

Aspectos sociales del reciclaje de residuos domésticos; perspectivas desde Jordania

La semana pasada estuvimos en la Universidad Hashemite en Jordania, enseñando a un grupo de jóvenes estudiantes cómo podemos reciclar de manera segura diferentes fracciones de residuos domésticos. Como parte de este curso de una semana, organizamos un día de seminarios interactivos y un juego de roles para que los estudiantes asimilen la importancia de aspectos psicológicos, procesos de toma de decisiones y otros aspectos socio-técnicos del reciclaje de residuos.

Robert Almqvist se une a nuestro grupo para realizar su tesis de maestría

Hola, mi nombre es Robert Almqvist y estoy realizando mi tesis de maestría en biología en el departamento de energía y tecnología de SLU. Soy un estudiante del programa suelo / planta para la agricultura, matriculado en SLU (Uppsala) desde 2014. En mi tesis de maestría, analizaré el compostaje de larvas de mosca soldado (BSF) y el posible efecto que tienen los diferentes pretratamientos sobre el contenido de aminoácidos de las larvas, así como el degradación de lignina / celulosa / hemicelulosa en los sustratos, siendo los sustratos cáscaras de plátano y naranja en este experimento.

Xiaoqin Zhou on research exchange at SLU from USTB

Dr. Xiaoqin Zhou, Assistant Professor of University of Science and Technology Beijing (USTB) is on a three week research exchange at Kretsloppsteknik. Yesterday, at a lunch seminar organised by the group, Xiaoqin presented about USTB and her own research activities. Specifically, she talked baout “toilet revolution” in rural China and how the country is currently in the process of upgrading its rural sanitation infrastructure. The “toilet revolution” campaign was launched by the Chinese central government since 2015 to improve the sanitary conditions in Mainland China. Thereafter, several campaigns have been launced in recent years such as“ National Tourism Reinvent Toilet Campaign” and “new toilet for rural toilet system Campaign” led by China National Tourism Administration (CNTA ), now called as Ministry of Culture and Tourism of the People’s Republic of China, and Ministry of Agriculture and Rural Affairs.

Curso de reciclaje seguro de nutrientes en Jordania

Esta semana, algunos integrantes del grupo (Sahar Dalahmeh, Mikael Pell, Annika Nordin, Cecilia Lalander y Prithvi Simha) estamos en Jordania, realizando un curso de 1 semana sobre reciclaje de varias fracciones de residuos domésticos. El curso se imparte en la Universidad Hashemite, ubicada a unos 50 km de la ciudad de Ammán (la capital). Un grupo de alrededor de 20 estudiantes muy entusiastas e inquietos está aprendiendo sobre diversos temas, como microbiología de aguas residuales, higienización, saneamiento separativo y deshidratación de orina, compostaje BSF, tratamiento in situ de aguas residuales, etc.
