Sanitärwende zur Sonnenwende: Führung Balmeggberg
Zur Sonnenwende am 21. Juni 2024 laden wir euch zu einer Führung auf dem Balmeggberg ein: vor Ort erleben wir, wie der Hof Kreisläufe schliesst, z.B. mit einem Hochleistungs-Wurmfilter, einer Kompost-Toilette oder einer Pflanzenkläranlage, die schon seit vielen Jahren das Abwasser des Betriebs einwandfrei reinigt.

VaLoo Workshop at KREIS-Haus: Closing water and nutrient cycles
ZHAW and VaLoo, are organizing a workshop in the KREIS-Haus research project.
PhD on Vermifiltration
I am currently doing a PhD which aims to answer the following questions: How does a full-scale vermifilter perform? (Case study: Soubeyran) How does the effluent of full-scale vermifiltration installations compare to irrigation and fertigation standards? What is the removal of pathogens, heavy metals, and common house-hold micropollutants? What are the mechanisms for nitrogen treatment…
The Ressourcer V1-2024 by EAR
The Resourcer V1 is designed to combine several circular processes: a grow house for seedlings and plants powered by passive and active solar power. Electric power will supply controlled LED, humidity and temperature adjustments to enhance and prolong the natural season in the mountain area (Emmental 700 m ü.M). a dry toilet, separating the (re-)source…
Stammhäuser
Unsere Welt ist bereits erbaut, doch wie können moderne, ökologische Themen in dieses bestehende Gefüge integriert werden? Die Stammhäuser der Wohnbaugenossenschaft Hofgarten sind herausragende Beispiele dafür.. Die geplante Instandsetzung dieser Gebäude legte besonderes Augenmerk auf die Minimierung des Ressourcenverbrauchs und die Anpassung an den Klimawandel. Durch eine sanfte Sanierung konnten bestehende Elemente erhalten und wiederverwendet…
Horizontal flow constructed wetland (HFCW) greywater treatment system
A Horizontal flow constructed wetland (HFCW) greywater recycling system is designed and installed by alchemia-nova GmbH at the apartment complex FELZ ZWEI, which was realized by VBAU Architecture in Zürich, Switzerland in 2021. ZHAW was evaluating the cleansing capacity and water quality; the potential water, energy and financial savings; as well as the user acceptability…
KREIS-Haus
What does a circular economy look like in everyday life? And most importantly, how does it feel? In the KREIS-Haus, visitors experience how a circular economy works in the context of construction and living. Additionally, they will have the opportunity to participate in a research project. KREIS-Haus stands for Klima und Ressourcen-Effizientes Suffizienz Haus (English:…
Pyrolysis plant for biochar from faeces
«Circular Cities» of the future are expected to reuse as many resources as possible. Today, human faeces from toilets are the most important source of nutrients in wastewater. The recovery of these nutrients is easier with dry toilets than with our current water flushing system. But how can this idea be technically implemented without impairing…
MODO – Nutrient recovery and water reuse
MODO stands for Mobile Ecotechnology Demonstration Object. The MODO shows how we can save water and keep it in a closed cycle. Inside the trailer is a urine-diverting dry toilet and a recirculating washing machine. Our researchers are investigating how the water can be purified after washing and reused for washing. Water losses are replenished…
