La caficultura es una de las principales actividades agrícolas en América Latina donde se involucran más de quince millones de familias. Es uno de las principales fuentes de ingreso en las exportaciones de países de América Latina y Africa.


El impacto ambiental de esta actividad es positivo, en cuanto representa servicios ambientales para países como El Salvador en donde los cafetales son los bosques del país. 

Sin embargo, en el tema de recursos hídricos estos están comprometidos por la contaminación que se genera en el beneficiado húmedo del café uva/cereza. Por tonelada de café uva/cereza se emplean hasta 8 m3 de agua, aportando una contaminación de 24 kg D.Q.O que en habitantes equivalentes representa 400 h.e.


La normativa ambiental en los países cafetaleros es cada vez mas estricta y limita la competitividad de la caficultura para los procesos de certificación de café sostenible. En este contexto es que se debe hacer un programa de manejo de los subproductos del café generados: agua de despulpado, lavado y la pulpa de café.


Se han venido desarrollando experiencias en el manejo y aprovechamiento de los subproductos del beneficiado del café desde los años 50 del siglo pasado pero estos esfuerzos no tienen la difusión necesaria para aprovecharlo en los países cafetaleros.


En la experiencia particular hemos trabajado el tratamiento anaeróbico con diferentes tipos de biodigestores en pequeña y mediana escala, así como en el manejo de la pulpa de café. También se han acompañado las experiencias de mejoramiento del beneficiado húmedo ´por medio de “PM+L” y buenas prácticas de manufactura.



La intención de compartir la experiencia es que se motive a mejorar la caficultura para beneficio de nuestros países y la competitividad de los productores y principalmente proteger los recursos hídricos que cada vez son mas escasos y mas contaminados

WISIONS & Asobiogás Workshop in Costa Rica!

News from WISIONS posted on July 19th, 2019

Holá from Costa Rica! WISIONS'and Asobiogás are holding a 2-day "Mutual Learning Workshop for Biogas Consolidation in Costa Rica". Our team member Willington Ortiz is one of the workshops facilitators that aims at promoting the implementation and use of biodigester technology in the agricultural sector in Costa Rica.Read moreMinimize

The workshop is only one step in a collaborative process seeking to (i) consolidate the use of biodigester technology in Costa Rica and (ii) accelerate the adoption of biogas solutions by small and medium-scale livestock farmers in the country.

The workshop gathered farmers, officials from public agencies promoting biodigester technology, suppliers of biodigesters and researchers of different disciplines. Aim of the workshop is to design concrete actions for addressing challenging fields in the implementation of the technology for family farms in Costa Rica. Biodigester technology is an economically viable and sound solutions for family farmers. However, the adoption of biogas solutions by small and medium-scale livestock farmers in the country is not easy to achieve. 

On the first day they visited a dairy farm, which already installed a bio digester and worked together on an understanding of the adoption process to the local conditions in the context of Costa Rica. During this mutual approach, they identified challenges for the implementation of bio digester technology in Costa Rica. On the second day they are aiming to design the concrete actions for addressing the evaluated challenges for bio digester technology.

Open-Source courses on Electronic Load Controller in Southeast Asia

News from WISIONS posted on July 17th, 2019

This collaborative project with Green Empowerment, Tonibung and Sibat currently promotes capacity building and technology access to Southeast-East Asian micro-hydro practitioners. Recently they offered intensive 2-week courses on the technology of Electronic Load Controllers (ELC), which is the crucial component for well-functioning for micro-hydro systems. Read moreMinimize

Our three collaboration partners Green EmpowermentTonibung (Malaysia) and Sibat(Phillipines) further pursued their commitment to spread open source knowledge on the crucial technology of ELC systems for micro-hydro systems and offered an intensive 2-week course for the knowledge exchange. The organization and execution of the in-person exchange was held at Tonibung and GE's Centre for Renewable Energy and Technology (CREATE) and involved an impressive program for participants from different regions of Southeast Asia. 

The participants could learn in theory lessons about the design theory behind ELCs, together with hands-on built-out sessions of ELC technology, so that the participants received a complete insight into the technology. All of the participants showed commitment and enthusiasm to lean about ELC technology and maintained their motivation throughout more than 3 hours of theory lessons each morning and additionally 10-12 hours of practice sessions every day. 

After absolving this course the participants were equipped with complete knowledge of all necessary components and how to build devices off the shelf in any country. Also the participants discussed collaboration opportunities with academic institutions and research organizations in order to step forward and continuing innovations in this technology. Even one participant committed to establish a manufacturing branch in his home workshop dedicated to ELC development. Generally speaking, the participants found the knowledge exchange useful in ensuring that there was a balance between the theoretical and practical elements of ELC design, assembly, and troubleshooting. There was also appreciation that time was given to allowing participants to share about their experiences in their own countries.
