Our mission is to empower individuals and communities to transform the production and use of energy so that it effectively enables sustainable development. Read more about WISIONS activities, goals and background.
Converting banana plant waste to cooking fuel in India
News from WISIONS posted on February 14th, 2014
To address these problems, the following steps were undertaken:
- The establishment of banana plantations applying micro-irrigation and other sustainable farming methods
- The development of a local biogas distribution system based on the anaerobic treatment of waste from the banana plantations
Firstly, a water supply system was constructed in Gundigere village, which required the drilling of two wells and the installation of a corresponding water pump and pipes. Four banana plantations were cultivated using resource-efficient farming methods. Adjacent to the plantations, two floating drum biogas digesters were installed.
Waste from banana cultivation (mainly the banana stalks and additional stems from the plants) is now being chopped up and fed into the biodigesters. The biogas produced by this method is distributed through two networks of pipelines (one for each biodigester) to 70 village households.From the initial harvesting of bananas in January 2013, approx. 63 tonnes of bananas were sold, yielding approx. €9,500 in net revenues for the project. Biogas distribution to households started in September 2013 and, by the end of the year, all 70 households were connected to the biogas network.
The results to date allow for the assumption that the pay-back period of the initial investment will be seven years. Furthermore, the project has demonstrated that it is possible for a biogas system to be based only on stem waste from banana plantations, despite the fact that the methane generation potential of these parts of the plant is much lower than that of the fruit and peel.
The project concept has good potential for replication, although the availability of water resources could be a significant physical constraint.

The deadline for submission of applications was 16th January 2014. The results will be published on our web page presumably at the beginning of March. Meanwhile, you can look at our ongoing projects here: SEPS Projects
Second International Wind Energy Symposium in Lima, Peru
News from WISIONS posted on December 20th, 2013
The three-day symposium was held from 20-22 November 2013 and was organized by Green Empowerment and Soluciones Prácticas. It intended to facilitate the exchange on small wind turbines in Latin America.
Existing technologies (commercially available systems as well as self-constructed approaches), successfully implemented projects, challenges faced as well as preliminary outcomes and lessons learned by the partnership were presented and discussed. Over 100 participants attended, coming from governments, private businesses, multi and bi-lateral institutions, NGOs, and more to share their experiences.
