Report on the use of biomethanation in Argentina

State of the Art in some Developing Countries

Summary

Biomethanation in Argentina is considered for the treatment of agro-industrial wastes, to reduce pollution and costs of wastewater treatment, and for the treatment of animal manure in locations far away from the energy-distribution systems. For the treatment of stillage the Upflow Anaerobic Sludge Blanket (UASB) reactor has been retained on the basis of the results obtained in a 100-litre semi-pilot-plant reactor. A 30-m3 UASB pilot plant is to be built in a leading distillery. The expected production of a full-scale plant would cover, 65 to 70% of the energy needs of the distillery. In biomethanation of manure, the only farms that could profit from biogas technology are the milking farms located far away from the electricity distribution system where the manure collected during the milking time could produce the energy needed to cool the milk from 22°C to 4°C.

Résumé

En Argentine la biométhanisation est essentiellement prise en compte d'une part pour le traitement des eaux résiduaries des agro-industries, pour réduire la pollution et le coût de traitement des ces déchets, et d'autre part pour le traitement de lisiers animaux dans des régions éloignées du réseau de distribution d'énergie. En ce qui concerne le traitement des eaux résiduaires, le procédé Upflow Anaerobic Sludge Blanket (UASB) a été retenu sur base des résultats obtenus dans un digesteur pilote de 100 1. Une installation pilote de 30 m3 sera construite dans une distillerie importante susceptible de couvrir 65 à 75% de ses besoins énergétiques avec la production attendue d'une installtion de taille réelle. En ce qui concerne la biométhanisation de lisier, les seules exploitations qui tireraient profit de la technologie sont les élevages laitiers situés loin du réseau de distribution d'électricité, où le lisier récolté pendant la traite pourrait produire l'énergie suffisant au refroidissement du lait.

Resumen

En Argentina se usa la biometanación para el tratamiento de residuos agro-industriales, para reducir los niveles de polución y el coste de tratamiento de aguas residules y para el tratamiento de estiercol animal en lugares lejanos de la red de distribución energética. Debido a los resultados obtenidos en un reactor semi-piloto de 100 litros se sigue utilizando el UASB para el tratamiento de los desechos de destileria. Se va a construir una planta piloto UASB en una de las destilerias más importantes. Las expectativas de producción cubren du un 65% a un 70% de las necesidades energéticas de la destileria. En relación con la biometanación de estiercol las únicas explotaciones agrarias que podrían beneficiarse de la tecnología del biogas son las granjas lecheras localizadas lejos de la red de distribución electrica donde el estiercol recogido durante el tiempo de ordeñe podría producir la energía necesaria para enfriar la leche de 22°C a 4°C.
