Abstract [sv]

Den här rapporten följer ett projektarbete som genomförts inom ramen för Minor Field Study, ett begrepp myntat av Sida, och som utförts i Quelimane, Mocambique. Uppdraget var att undersöka om ett system för anaerobisk fermentering, eller biogasproduktion, kunde konstrueras, underhållas och användas i en lantlig miljö med tillämpning av lokal kompetens, lokala verktyg och begränsade resurser. Som förberedelse inför fältstudien genomfördes litteraturstudier och konstruktion av flera prototyper, samt studiebesök i Sverige. Under fältstudien samlade projektet de nödvändiga verktygen och hårdvaran och samverkade med olika personer för att aktualisera uppförandet av systemet. Efter ungefär fem veckors drift av systemet producerade det biogas i en tillräcklig takt för att samlas i behållare och därefter förbrännas i ett gaskök. Fältstudien avslutades när det fungerade systemet lämnades över till kommunen Quelimane under en slutlig formell presentation.

Abstract [en]

This paper covers the work of a project within the frame of a Minor Field Study, as defined by Sida, that is carried out in Quelimane, Mozambique. The objective was to investigate whether a system of anaerobic fermentation, or biogas production, could be constructed, operated and made use of in a rural area using local knowledge and tools and with limited resources. This is prepared for by constructing several prototypes, performing desk research and conducting field trips in Sweden before the actual field study in Africa. During the field study the project gathered the required tools and hardware and also connected with people in order to actualize the construction of the system. After about five weeks of operation the system produced biogas in a rate high enough to gather it in containers and combust it in a gas stove. The field study was finished when the operational system is handed over to the municipality of Quelimane during a final formal presentation.
