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.

Productive Use of Biogas at Dairy and Pig Farms in Costa Rica
News from WISIONS posted on June 2nd, 2017
This project is being led by local partners Viogaz. Their recent work includes the successful identification of farmers aiming to participate in the programme, and the assessment of farms serving as pilot project sites. Via surveys and other analyses the farmer’s needs for a biodigester could be determined, as well as their possible uses of the new technology.
Since Viogaz is a partner of Kiva Microfunds, an organisation which allows people to lend money to low-income entrepreneurs, they were able to offer a financing option to the selected farmers, helping them implement the anaerobic technology (biodigesters).
Furthermore, Viogaz designed the appropriate biodigestion system for each user, considering a variety of factors. Most of the systems have already been installed, and all of the installed digesters have begun operation. All users were trained on how to run and maintain the biodigesters.
The next working steps of this project include monitoring of the systems, connection of the technology to its designated end uses, as well as further testing, validation, and training sessions.

Grid-Connected Biomass Gasification in Sri Lanka
News from WISIONS posted on April 12th, 2017
A 20 kW power pellet (wood) gasifier and engine was purchased, together with an induction generator. The team designed and manufactured a suitable woodcutter and constructed a power house. Subsequently, they signed the "Standardised Power Purchase Agreement" with the Ceylon Electricity Board, which permits the energy produced to be sold to the grid. As a last step, the power plant was connected to the national grid. To ensure sustainability, a wood supply chain was established with the farmers, plant operators were trained and a 20 year power purchase agreement was signed.
Monitoring of the plant’s performance is still on-going. For more general information on this SEPS project, please visit our project page: Introducing grid-connected biomass gasification units for rural energy access and community development.
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
