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.

Biogas Production from Slaughterhouse Wastewater in Quito, Ecuador

News from WISIONS posted on April 27th, 2017

One of our SEPS projects in Ecuador aims to demonstrate the potential for producing biogas from slaughterhouse wastewater treatment. The biogas will then be used for the purpose of heating water, thereby minimising the use of fossil fuels and the associated expenditure on energy.Read moreMinimize

This project is led by CIMNE, who started implementing this technology in mid-2016. Over the last few months, several feasibility and measurement studies have been undertaken, including wastewater flow and characterisation, biogas potential, and the calculation of fuel/water consumption of a boiler used for heating and drying processes at the slaughterhouse.

After designing the biodigesters, four tubular units (100m3 each) were constructed on-site by a local manufacturer. It is estimated these will produce 157m3 of biogas per day from 72m3 of wastewater.

As well as monitoring the operation of the digesters, next steps include the installation of distribution lines transporting the biogas to its point of use: a new boiler to be powered by sustainable energy.

Photos of the project’s progress are available on our Facebook page, while more general information is available on our project page: Biogas from Slaughterhouse Waste Water Treatment for Heating Purposes

Grid-Connected Biomass Gasification in Sri Lanka

News from WISIONS posted on April 12th, 2017

One of our SEPS projects in Sri Lanka established a pilot community-based grid-connected wood gasification power plant (20 kW) in the village of Batugammana. It serves as an environmentally friendly income-generating opportunity for the rural population in Sri Lanka. Farmers living in the village supply sustainably grown fuel wood to power the plant, which in turn generates power that is eventually sold to the national grid.Read moreMinimize
Biomass energy has the potential to generate income for rural farmers as there is an attractive feed-in tariff for biomass power in Sri Lanka. This project, which has recently been successfully completed, mobilised the farmers in the village, formed a community-based company, conducted feasibility studies and obtained an energy permit from the Sri Lanka Sustainable Energy Authority for the grid-connected biomass power project.

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.
