In the framework of an ongoing funded civil engineering project, University of Genoa collaborated in the dimensioning and realization project of a large size biogas plant. The background project foresees the construction of a recovery centre which is being constructed in a rural area of Arusha’s region. This centre will be mainly used as school but also as professional institute for conscious reintegration into the community. The whole project has been designed on the basis of a rational use of resources, of a sustainable integration in the local context and of a responsible sharing of the used techniques. The technology used is based on a mechanism able to produce cob bricks (similar to LEGO bricks) with excellent mechanical properties.
The designated area will measure about 3 hectares and will include a dormitory, suitable for about 70 people, several teaching classrooms, some laboratories, kitchen, refectory, recreation’s rooms and a community area. As anticipated, the project will foresee the implementation of some renewable energy solutions able to meet, fully or partially, the local energy requests as far as electric and thermal needs are concerned. First of all, a biodigester that will cover the entire thermal energy supply of the entire structure and will be used for domestic applications (mainly for kitchen). The biodigester has been designed by University of Genoa and will be realized in next months. The organic matrix, input for the digester, will mainly comes from animal manures with some addition of agriculture discards. The interesting thing of this project will be the redaction of a simple instruction manual for the daily utilization of the plant together with a smart guide to settle the correct dosages of the inlet.
