Adapting the German Bioenergy Village Concept to Los Ríos Region in Southern Chile: Integrating Community, Water, Energy and Organic Waste Management

摘要

German bioenergy villages (BEVs) achieve high energy efficiency, a low carbon footprint, optimal organic waste management, and community integration. This research found that the German approach applied to Los Ríos Region is technically feasible, but economic and environmental constraints make its application unfeasible. However, modifications to the original concept are proposed as a new BEV concept adapted for southern Chile. Firstly, in urban neighborhoods of cities saturated by air pollution or in rural villages, district heating networks fueled by wood biomass could be effectively applied thanks to the efficiency gained with centralized boilers and their low emissions of fine dust. Similar efficiency could be reached in houses using pellet stoves. Secondly, management of domestic organic waste could supply enough biogas for cooking, allowing energy savings and the replacement of traditional low-performance stoves, reducing the demand for firewood and air pollution. Finally, a specific proposed system for organic waste and water management would allow a better functioning of biodigesters for black waters and organic waste, and constructed wetlands for grey waters. This combination could optimally recover over 80% of the total wastewater and 90% of the total nutrients and provide a new source of energy, in addition to enhancing the biodiversity of the place.
