La Paz, Bolivia
ETHOS has been partnering with the La Paz, Bolivia branch of our partner, Prolena, since 2003. Prolena has given our students an opportunity to work on stoves, solar cookers, distillations, wood dyers, and several other technologies for the region.
Project Highlight: Essential Oils Distillation
Beginning in 2011, the essential oils distillation project makes use of a very abundant resource in Bolivia: orange peels. The project involves a simple distillation of blended orange peels and water in order to retrieve the essential oils from the peels. These oils can then be collected and sold by local entrepreneurs for cooking, medicinal, aromatherapy and other purposes. In 2013, ETHOS students implemented a recycle loop to the system so that water used in the condenser could be reused. This improved the efficiency of the system and reduced the resources necessary for operation.
