Biodigesters for Southeast Asia: Exchanging Knowledge

News from WISIONS posted on July 10th, 2019

There happened a lot since the last report from our partner GreenEmpowerment and their activities in Southeast Asia. After pitching their Biodigester technology in Sri Lanka in 2018 and conducting previous knowledge exchanges, they hosted practice trainings in Malaysia in order to train practitioners on biogas digester systems and showcasing it to local communities.Read moreMinimize

After holding trainings and workshops on biogas technology in Sri Lanka for participants from Malaysia and the Philippines (see News from March 2018 and News from October 2018 ), the third and final training on the technology hold place now in Nampasan Village (Sabah State, Malaysia).  The aim of this training was to design and install a tubular gas biogas digester based on already installed examples in Latin America. With slight improvements to the local conditions in Malaysia on the geomembrane , the biodigester got more durable and puncture resistant to the environmental circumstances.  Also the usage of kitchen waste for the biodigesters had to be considered, therefore improved geomembrane has been chosen to use. 

 

The trainers were practitioners from former trainings on biogas digester technology and were supposed to work with the local community members to install biogas digesters in the village.  The trainees included staff of KOPELPACOS Trust and TONIBUNG CREATE as well as from the local NGO CLEAR. The first day was focused on the theoretical knowledge transfer on the design of the digesters considered the amount of waste and the need for the created fuel. Following this, the theoretical knowledge got applied and both the trainers and trainees installed biogas digesters. For practical reasons the location was at the pig farm of CLEAR, where the biogas digester could directly showcase its capabilities. The results of this installed biogas digester are impressive: 230 liters of biol and 3.095 liters of biogas per day, which is enough to cook for 10 hours or to cook for 5 hours and burn 2 gas lamps for 6 hours each!

RedBioLAC Webinar on "Biogás en la producción de café"

News from WISIONS posted on July 8th, 2019

Our partner RedbioLAC just announced a great webinar about the use of biodigesters and coffee production. It will take place on 17th July on 8:00 A.M. CST (16:00 P.M. CEST). Register here following the link! The webinar will be in Spanish only!Register here! Read moreMinimize

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
