Repair of more biogas plants in Helambu

After the emergency aid has been expired, atmosfair is enhancing the second phase of the reconstruction. In the first phase of our engagement, we were distributing efficient cookstoves and solar lighting as most needed resources. But now it´s about repairing the damaged biogas plants: during the earthquakes, many biogas plants have been destroyed.

In a small-scale biogas plant (about 6m³) cow dung is transformed into biogas and sludge by microorganisms. Traditional cooking on wood is not only expensive and damages surrounding forests. Especially women´s and children´s health is harmed in many cases due to heavy emissions of smoke and carbon black. Luckily, they can replace the fuel wood with biogas: two or three cows provide enough dung for cooking biogas for a five-member family.

Moreover, the sludge from fermentation can be used as a soil conditioner on the farmer´s fields. Many of the biogas plants are connected to a latrine, hence improving the hygienic situation in many households.

Thus, the importance of biogas plants for the local people is enormous in many ways. Thanks to a generous donation in 2015, we were able to repair already 316 plants until now. But there is still a great need for repair in Nepal. With your help, we therefore want to repair 56 more plants in the region of Helambu nearby the Climate Trek.

Reparatur weiterer Biogasanlagen in Helambu

Nachdem die Soforthilfen für die Erdbebenopfer in Nepal ausgelaufen sind, wird atmosfair nun die zweite Phase des Wiederaufbaus verstärken. Während wir in der ersten Phase unseres Engagements effiziente Öfen und Solarbeleuchtung als nötigste Mittel verteilt haben, wollen wir jetzt vermehrt beschädigte Biogasanlagen reparieren lassen. Durch die Erdbeben 2015 sind neben den Lodges auch viele Biogasanlagen zerstört worden.

In einer Kleinbiogasanlage (Fassung etwa 6 m³) wird Kuhdung von Mikroorganismen in Biogas und Schlamm umgewandelt. Das traditionelle Kochen mit Holz ist nicht nur teuer und schadet den Wäldern ringsum, sondern bereitet insbesondere Frauen und Kindern Gesundheitsprobleme durch starke Ruß- und Rauchentwicklung. Mit dem Biogas können sie das Feuerholz ersetzen: Der Dung von zwei bis drei Kühen liefert bereits ausreichend Biogas zum Kochen für eine fünfköpfige Familie.

Der Schlamm aus der Gärung eignet sich außerdem als Bodenverbesserer für die Felder der Bauern und Bäuerinnen. Viele der Biogasanlagen sind mit einer Latrine verbunden und verbessen somit die hygienische Situation der Haushalte.

Die Bedeutung der Biogasanlagen für die Menschen vor Ort ist deshalb in vielerlei Hinsicht enorm. Durch eine großzügige Spende konnten wir seit 2015 bereits 316 Biogasanlagen in Bhimtar reparieren. Es besteht aber immer noch ein großer Bedarf an Reparaturarbeiten bei vielen Anlagen in Nepal. Mit Ihrer Hilfe wollen wir daher jetzt 56 weitere Anlagen in der Region Helambu nahe des Climate Treks reparieren.

Health study from Rwandan refugee camp published

Using our efficient cookstoves improved the health of the users. This is shown in a field study which has been published now.

atmosfair has conducted a health study in the Rwandan refugee camp in Kiziba in cooperation with physicians of the University of Lübeck together with the non-profit organization Buana from Hamburg. In spring 2016, the research was completed. In this study, the lung function of nearly 500 participating women was tested both before and eight months after distribution of the Save80 cookstoves. Thus, the influence of the open fire and of the Save80 on people´s pulmonary health has been investigated. This is the first field study of its kind.

All test persons showed improved lung function values already eight months after the cookstove distribution. The women perceived this improvement as alleviation of their symptoms, too. Test persons, whose brochial tubes had been worst affected by the open fire before did show the most significant improvement in their values. It might therefore be assumed that a long-term reduction of damage of the lung and of the bronchial system will minimize the risk of late effects such as malignant lung tumours as well. 

An executive summary of the study (only German version) is available under the following link:

Gesundheitsstudie aus ruandischem Flüchtlingscamp veröffentlicht

Die Ergebnisse einer Feldstudie, die eine Verbesserung der Nutzerinnen-Gesundheit durch unsere effizienten Öfen in einem ruandischen Flüchtlingslager belegen, wurden nun veröffentlicht.

Gemeinsam mit Ärzten der Universität Lübeck sowie des gemeinnützigen Vereins Buana aus Hamburg hat atmosfair eine Gesundheitsstudie im Flüchtlingscamp Kiziba in Ruanda durchgeführt. Im Frühjahr 2016 wurden die Untersuchungen abgeschlossen. Knapp 500 Frauen nahmen an der Studie teil, bei der vor sowie acht Monate nach Verteilung der Save80-Öfen ein Lungenfunktionstest durchgeführt wurde. So konnten die Folgen des offenen Feuers sowie der Einfluss der Öfen auf die Lungengesundheit ermittelt werden. Dabei handelt es sich um die erste Feldstudie dieser Art.

Bereits acht Monate nach Einführung der Öfen konnte gezeigt werden, dass sich die Lungenfunktionswerte bei allen Probandinnen messbar verbessert hatten. Diese Verbesserung wird auch von den Probandinnen selbst als Linderung ihrer Beschwerden wahrgenommen. Die  Verbesserung ist bei den Frauen am deutlichsten, deren Bronchien durch das Kochen am offenen Feuer zuvor am stärksten geschädigt waren. Es darf daher vermutet werden, dass eine dauerhafte Reduktion der Belastung von Lunge und Bronchialsystem auch das Risiko von Spätfolgen minimiert, wie z.B. das Auftreten von bösartigen Tumoren in der Lunge.

Die Studie ist in einer Kurzfassung auf unserer Projekt-Website zu finden sowie unter dem folgenden Link direkt einsehbar:

Pilot project for the reconstruction of biogas plants in Nepal completed

atmosfair contributes to the reconstruction in Nepal which is unfortunately still progressing very slowly. Hundreds of thousands of houses have been destroyed and almost 9,000 people were killed during the earthquakes in April and May 2015. Moreover, many biogas plants have been damaged which were built thanks to atmosfair´s climate protection fees. Until today, atmosfair got 310 plants repaired in Bhimtar, Sindupalchok, allowing for the households to return to normality.

Even before the earthquake, the village of Bhimtar, encompassing 900 households and located 30km east of Kathmandu, had already been one of the poorest communities in the Sindupalchok district. Sindupalchok was hit particularly hard during the earthquakes: In Bhimtar, all homes were partly or completely destroyed, including more than 300 biogas plants of the commune. Most inhabitants are so poor that they are still living in temporary shelters out of bamboo and straw and they cannot afford a repair of their biogas plants.

This is especially unfortunate as biogas plants are very popular in rural Nepal: Thanks to them, households are able to cook smoke-free and cost-effective. Moreover, biogas plants are true climate protectors: Each one is saving three tons CO2 per year compared to the traditional three-stone-fire. Local communities had to fall back on those, since the earthquakes had damaged the biogas plants. The carbon black harms people´s respiratory tracts. In addition, households must spend more time and money to get firewood for cooking.

Our project partner BSP-N (Biogas Sector Partnership Nepal) is coordinating the reconstruction process. BSP-N is one of the most experienced actors in the Nepalese biogas sector. Its manager Bala Ram Shretsha is standing up whole-heartedly for the wider distribution of the technology in his country. This is why repairs have been going on fast and efficiently. Mostly small parts had many defects such as valves, gas taps, manometers or hosepipes and thus had to be replaced. Other parts like inlets or gas cookers could be fixed in most cases.

atmosfair´s consultant Bhai Maharja found the villagers very happy at his evaluation visit. “The repair of the biogas plants means a step forward towards everyday life for many people”, according to Maharjan. Biogas user Bharar Danuwar and her family are finally able to cook on this innovative technology again. “We are so happy and grateful that our biogas plant is working again: Now we can cook three meals a day and we don´t have to worry where to get the firewood from. After the earthquakes we had to burn the wood of our broken homes. However, this is already used up by now.”

But our pilot project did not only make  a difference in Bhimtar: After the successful  restorations, the German “Kreditanstalt für Wiederaufbau” (KfW, a German credit institute for reconstruction) and the Nepalese Alternative Energy Promotion Centre (APEC) decided to expand the programme on other districts, too. We are very pleased to continue the cooperation as the major part of the earthquake damages is not yet reconstructed.

We were able to finance the repair measures, which are now completed, thanks to generous donations of our patron and climate scientist Prof. Dr. Mojib Latif. Having received the “Deutscher Umweltpreis” (a national German environmental award) in 2015, Mr. Latif donated the whole prize money to our projects. The fixing of the biogas plants is part of our initiative “New energy for Nepal” which was started by atmosfair and the German association of sustainable tour operators “forum anders reisen” after the earthquakes in 2015.
