Enhancing low-carbon food value chains in the Guatemalan highlands

News from WISIONS posted on October 7th, 2014

Our partner organisation Alterna, which has been supported under the WISIONS SEPS scheme, successfully implemented 25 small scale biodigester systems in Guatemala. The technology showed a high dissemination potential and Alterna expects to install nine small scale biodigester systems without the need for subsidies in the upcoming months. Read moreMinimize

The aim of this SEPS project was to use biodigester systems as a simple, affordable and user-friendly alternative for small-scale food productive units. Besides the planning and installation of the technology, marketing and communication were important factors of the project, seeking collaboration with stakeholders and raising awareness of low-carbon technologies amongst the general public. 

Many lessons have been learned during the last two years: 

  • The feeding process for the biodigester systems has been greatly simplified by incorporating a purge in the anaerobic reactor that minimizes the time spent on these tasks
  • The environmental and socio-economic potential of bioslurry: the "new brown gold" will allow users to pay back the investment in less than three years, which will make the technology very attractive to investors and financers
  • Slaughterhouses and municipal markets, coffee and dairy farms, hotels and restaurants, as well as the industrial sector are proving that digesters are an opportunity to reduce production costs while complying with environmental policy 
  • Alterna and Viogaz S.A. are now working as strategic allies. This bond will provide the capacities necessary to response to the increasing interest in the technology in Guatemala


Concrete Turbine Manual video from our partners at Janathakshan

News from WISIONS posted on September 29th, 2014

Our partners at Janathakshan in Sri Lanka have made a video to describe their low-cost, easy to assemble pico-hydro concrete turbine. As of February 2014, this turbine has been deployed in 45 Sri Lankan villages, of which over 85% are still functional. Read moreMinimize

The casing for this turbine is built from concrete, while the runner is constructed from aluminium and fibre glass. The turbine efficiency is about 70% and it possesses a number of advantages over its steel counterparts.

In order to share their micro-hydro technology, Janathakshan have made a video demonstrating the steps required to build the concrete turbine. It does not provide all the details, but gives a good overview of the system.
