WISIONS of Sustainability
The main objective of WISIONS is to make clean energy a default solution for basic energy needs in developing regions, by helping local partners to identify successes and bring them to scale through regional networks, marketing and demonstration.

Handbook on Biogas Integration into Sustainable Farming Systems
News from WISIONS posted on January 9th, 2017
Biogas generation through the anaerobic digestion of biomass has been carried out successfully in India and other parts of the world for decades. In this SEPS project, biogas was produced mainly from banana stem-waste at small rural banana plantations and then distributed to more than 70 households in the village of Gundigere for cooking purposes. The project has demonstrated that a biogas system can be based solely on stem waste from banana plantations, although the methane generation potential of these parts of the plant is much lower than that of fruit and peel.
IEI’s in-depth handbook offers potential users information on:
- Integrated banana cultivation, biogas generation and stove-fuel delivery
- Operation at family/community/village level rather than industrial scale
- Actual implementation and operation in India
- Background information on technologies and resources
Enhancing Productive Biogas Use in Mexico
News from WISIONS posted on February 4th, 2016
In the second phase, the project aimed to demonstrate the feasibility of adapting and applying commercial gasoline motors available in the Mexican market in order to provide mechanical and/or electric power to small and medium farmers by using their biogas. In this phase, there were five significant areas of work: biogas filtration, matching energy production and use, motor sizing and design, grid interconnection, and training and maintenance. Sixteen motors have been adapted and installed by IRRI.
The project has already led to significant advances in the application of biogas for small scale electric power (between 5 and 10 kW) and has opened the door to the further development of the technology. All the installed motors are currently under a monitoring and maintenance regime for the next 12 months to improve data on the operating parameters and benefits of these systems.
Grid-Connected Biomass Gasification Plants for Rural Energy Access in Sri Lanka
News from WISIONS posted on October 21st, 2015
One of the central goals of the project is to demonstrate the technical and economical feasibility of selling electricity from a community-based wood-gasification plant under a standardised power purchase agreement with the Ceylon Electricity Board (a state-owned utility). This project will help to build farmers’ confidence in the new technology and on the market for sustainably grown fuel wood; thereby creating an enabling environment for replicating this community-based model in about 10,000 rural villages in Sri Lanka.
After selecting the village of Batugammana, mobilising the local community and establishing business and management models, the implementing organization Energy Forum purchased and installed the "Power Pellet", an automated biomass gasifier which was success fully tested in Sri Lanka for the first time during this project. Several technical issues and regulatory obstacles has been successfully resolved during trials, as a result of which the plant was successfully commissioned in Batugammana.
Further recent project progress and achievements include
- The successful connection of the plant to the national grid
- The signing of a power purchase agreement with the Ceylon Electricity Board
- The establishment of a fuel wood supply chain
- The training and capacity building of plant operators
- The monitoring of the performance of the plant
