International Rainwater Harvesting Alliance - IRHA

Sujets :

IRHA's mandate is to promote rainwater as an effective and sustainable solution to water scarcity and climate extremes.

The International Rainwater Harvesting Alliance (IRHA) is a Swiss non-governmental organisation based in Geneva since 2002. IRHA’s mandate is to promote rainwater as a sustainable solution to water scarcity, climate extremes and natural disasters that undermine ecosystems and communities.

IRHA’s programme is divided into  5 components:

  1. Rainwater for water, sanitation and hygiene
  2. Rainfed agriculture and food sovereignty
  3. Disaster risk management and ecosystem restoration
  4. Urban rainwater
  5. Alliance

 

Our action is based on the implementation of rainwater management projects in developing countries where access to drinking water and vulnerability to climate change are daily problems, directly and negatively impacting community life. Our intervention revolves around 3 components:

  • Implementation of projects
  • Capacity Building
  • Support for the development of an integrated natural resource management policy.

 

We offer our partners :

  • Expertise to plan, develop and build stormwater management systems and operationally demonstrate the benefits of this resource.
    Decision-making tools to provide local decision-makers with the tools necessary for the proper management of infrastructures and to ensure the sustainability of investments.
  • Training to strengthen the technical and management capacities of local decision-makers, and technical services and young professionals (students in civil engineering, architecture, etc.).
  • Support for the development of local and regional policies/strategies for the conservation and management of water resources, in order to strengthen resilience and the capacity to adapt to climate change.

 

We pay great attention to monitoring/evaluating the performance of our projects with our local partners, to developing contextualized solutions based on a detailed understanding of needs. Results-based project management, monitoring of indicators and achievement of objectives, allows us to better perceive the impact of our interventions on the basis of quantifiable results.
The impact of our actions since 2002 is: + 1,184,000 people benefiting daily from drinking water resources, + 140 rainwater collection tanks, + 200 school gardens, 64 schools and 9 health centers in 14 countries of intervention.

The Ressourcer V1-2024 by EAR

Informations

The Ressourcer V1-2024 by EAR

Sujets :

  • Collecte & Traitement
  • Réutilisation & Production

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 material into liquids and solids.
  • a feces fermentation and/or worm compost installation with drawers or a box system.
  • fermented urine with evaporation installation and treated fertilizer as outcome.
  • streetnoise absorption for a better garden sound.
  • rainwater collector to repurpose.
  • 30cm lower planting bed to use earth’s warmth into the machinery.
  • tree-grow-facility as in winter protection.
  • material to construct the Resourcer V1 is re-used from another construction site
  • prototype and study facility like using the irradiation of the battery to enhance the composting.
  • Researching on psychology of water-flush sounds.
  • Collecting data on the experience of the usage of such a system from the makers and the audience of EAR.

 

Purpose and goal: 


The Resourcer V1 project aims to grow organic material such as seedlings, bacteria, biological material, and plants using the techniques of the Resourcer V1 system. This project presents a perfect challenge for a dedicated team  and aligns with the core vision of EAR.

The Resourcer V1 is an off-grid system that consists of a greenhouse with four compartments. The first compartment contains a dry-toilet and urinoir, the second compartment controls the compost climate of feces and greens, the third compartment facilitates urine-to-fertilizer evaporation, and the fourth compartment is used for growing seedlings, plants, and conducting other experiments.

The surrounding EAR garden of approximately 100m2 can nurture the seedlings that grow into food. The kitchen and community will process these plants, keep the seeds separated for the next season, and mix coffee waste and tea leaves into the circular processes. Additionally, these processes can be used to grow mushrooms and produce vegan leather. The (wurm-)compost produced by the Resourcer can be mixed into the normal compost.

The construction will also improve the soundscape in the garden, since it is built with a sound-absorption that lowers the traffic-noise.

In summary, the Resourcer V1 project is an off-grid system that aims to grow organic material using a combination of greenhouse and circular processes, aligning with the core vision of EAR. The surrounding garden, kitchen, and community play an important role in nurturing the seedlings, processing the plants, and contributing to the circular processes that keep changing and hopefully expanding.

Dimensions

The dimensions of the project are (lxbxh)  6mx 1,5 (2m roof) x 1.9-2.2m and the construction takes place in 2024. It will replace the existing shed that needs complete renovation.

Realization / timeframe 

EAR will invite volunteers who have great expertise on different aspects of the project. Together we want to make a journey into combining several processes in 1 dedicated machinery that intrinsically motivates to mix in the different circularities.


Ending up with a real yield with home-made fertilizer, understanding of great compost, a knowledge on different fermenting systems, clever evaporation, controlling low-energy computers for climate-regulation and many more interactions will be found in the realization of this project.

Pls reach out to Philipp Markus for more details on the timeframe etc…

Die Welt ist fertig gebaut

Stammhäuser

Sujets :

  • Collecte & Traitement
  • Habitation & Vie
  • Réutilisation & Production

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 werden, wie beispielsweise die Küchen. Andere Elemente wie Duschen wurden komplett neu gestaltet, jedoch auch im Kreislaufkonzept durchdacht. Die Bewohner tragen aktiv zum Klimaschutz bei, indem sie einen Teil der Wärme aus dem Abwasser während des Duschens einfangen und ins System zurückführen. Diese innovative Wärmerückgewinnung findet direkt in der Duschrinne statt und wurde in Zusammenarbeit mit unserem Industriepartner Joulia umgesetzt, die verschiedene Bauformen der WRG-Rinnen anbieten. Ziel war es, die grösstmögliche Effizienz zu erreichen, was uns gelungen ist. Die Herausforderung bestand darin, den nötigen Platzbedarf für den Wärmetauscher zu finden. Da sich dieser direkt in der Duschrinne befindet, musste die Holzbalkendecke mit Schlackefüllung als Raum herhalten. Gleichzeitig wollten wir keine Kompromisse in Bezug auf Dichtigkeit, Schallschutz und Brandschutz machen. Das Fazit lautet: Es geht, und zwar mit Erfolg.

Neben diesem aktiven Beitrag zum Klimaschutz wurde auch an die Klimaanpassung gedacht. Das Gebäude profitiert von einem begrünten Freiraum abseits der Strassen, der speziell für die Hitzeminderung optimiert wurde. Ab dem Frühling 2024 tragen offene Mulden zur Hitzeminderung bei, indem sie das Dachwasser verdunsten und versickern lassen. Vor den Mulden sind einzelne Regentonnen platziert, die eine einfache Nutzung des Regenwassers ermöglichen.

Solche Projekte erfordern eine offene Bauherrschaft und grosses Vertrauen in das Projektteam. Die Wohnbaugenossenschaft Hofgarten hat uns beides grosszügig geschenkt.

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: climate and resource efficient sufficiency house). The project shows how a functioning circular economy can be implemented in the smallest of spaces. From the building materials to the nutrients in the wastewater – everything is in circulation.

The KREIS-Haus is a joint project of the research group Eco-technology at ZHAW and the Synergy Village association, which is the location of the KREIS-Haus. The research group leads the research and educational projects in the house. The Synergy Village association is the implementation partner and owner of the house. The association is responsible for the operation of the KREIS-Haus, supports the research work and welcomes visitors to the idyllic grounds.

Pyrolysis plant for biochar from faeces

Pyrolysis plant for biochar from faeces

Sujets :

  • Collecte & Traitement
  • Réutilisation & Production

«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 community sanitation?

Collected material from dry toilets can be hygienized by means of pyrolysis (a heat process of > 350 °C). Experiments and measurements have shown that most nutrients from faeces are found in biochar after the pyrolysis process. These could easily be reused in agriculture or transported, which would complete the cycle. Our current research focuses on the optimal operating concept, the availability of nutrients in pyrolysis carbons and the role a system such as this could play in the future circular economy (or in space stations).

MODO – Nutrient recovery and water reuse

Sujets :

  • Collecte & Traitement
  • Habitation & Vie

 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 with rainwater. Thanks to a photovoltaic system on the roof of the trailer, this concept makes it possible to develop a laundromat that is completely independent of the central water and electricity supply. This innovation is currently being developed into a marketable solution in South Africa as part of the LaundReCycle project. In the scope of scientific experiments, the faeces are converted to biochar by pyrolysis and used in agriculture to improve the soil. If no experiments are running, the faeces are composted in a worm composter. In both ways, the nutrients are returned to the nutrient cycle.
