Other Technologies

Malena cookstove

The Malena cookstove is a technology designed by EnDev Bolivia that has been implemented throughout the country since 2007 (Malena stands for Mejor Aprovechamiento de Leña, i.e. better use of firewood). It uses wood or animal waste and is built with local material (improved clay mix); its design has been certified to guarantee that it allows for a decrease in fuel consumption when cooking food. These cookstoves have a chimney that eliminates smoke and toxic gases from inside the house, thus reducing health risks for women and children, as they are the ones who spend more time in the kitchen.

This technology has had considerable impact because families spend considerably less time collecting firewood and less money in case they have to purchase it. The improvement in families’ health is also transcendental, as is the reduction in deforestation.

This technology has currently been transferred to local partners for its construction and implementation.

These cookstoves have a design that reduces the amount of firewood required to cook. Thanks to their reduced size, they can also be easily transported.

 

EnDev designed and developed this portable cookstove which is being produced since 2016 and whose slogan, in Spanish, is “Augusta, la cocina que más nos gusta” (Augusta, the stove we like the most). Augusta stoves are wood-fired and built by local manufacturers. Energetic Promoters (EPs) are in charge of selling these stoves. Their design has an external metal protection in the form of a barred cage that protects the user from the heat while cooking. These stoves save 38% wood in comparison to a traditional stove.

Biodigesters

In 2003, low-cost biodigesters were implemented in regions with cold climates, such as the Bolivian highlands and became a milestone in the development of this technology worldwide. After going through a series of smaller projects, in 2007 EnDev Bolivia started a biodigester project at the national level that led to standardizing the technology, training professionals and field technicians, as well as creating the “CRB3 Laboratory” (Centre for Research on Biodigesters, Biogas and Biol) located in Viacha, La Paz, with the participation of the public Universidad Mayor de San Andrés (UMSA). It also developed successful social strategies in the implementation of biodigesters in alliance with other institutions.

Currently EnDev Bolivia no longer works in this component and transmitted its knowledge and technology to local partners and universities for further implementation.

“Sembrando Gas” (Sowing Gas)

Sembrando Gas en Bolivia emerged as a strategic alliance between the Bolivian State -through Yacimientos Petrolíferos Fiscales Bolivianos, YPFB (the Bolivian state-owned petrol and gas company), international cooperation and the private sector. This alliance was coordinated by the Bolivian CEDES (Business Council for Sustainable Development) Foundation, who, in turn, implement a project aimed at improving the urban populations’ quality of life through access to natural gas in social infrastructures, such as educational units and health centres.

The project was intended to increase the number of people who have access to modern energy sources in a reliable and sustainable way in Bolivia. Additionally, the project enabled the generation of various temporary direct jobs, in authorized installation companies, as well as indirect jobs, in the production of ovens and stoves. Students, teachers and parents were also trained in energy and environment issues.

The project concluded successfully in 2008. The Bolivian government is currently in charge of further implementation activities.

Energy for Social Infrastructure

One of EnDev Bolivia’s main pillars was the component Energy for Social Infrastructure, which was aimed at improving the use, coverage and quality of health and education services, boarding schools and community centres, by providing them with access to modern energy.

The work in this component concluded in 2015. However, other components have included some of its measures to give continuity to the work that was carried out.
