The aim of this study was to establish sustainably feasible areas for the implementation of anaerobic co-digestion plants for agricultural wastes (cattle/swine slurries and cereal crop wastes). The methodology was based on the use of geographic information systems (GIS), the analytic hierarchy process (AHP) and map algebra generated from hedges related to environmental, social and economic constraints. The GIS model obtained was applied to a region of Chile (Bío Bío Region) as a case study showing the energy potential (205 MW-h) of agricultural wastes (swine/cattle manures and cereal crop wastes) and thereby assessing its energy contribution (3.5%) at country level (Chile). From this model, it was possible to spatially identify the influence of each factor (environmental, economic and social) when defining suitable areas for the siting of anaerobic co-digestion plants. In conclusion, GIS-based models establish appropriate areas for the location of anaerobic co-digestion plants in the revaluation of agricultural waste from the production of energy through biogas production.
本研究的目的是为农业废弃物(牛/猪粪便和谷物作物废弃物)厌氧共消化厂的实施确定可持续可行的区域。该方法基于地理信息系统(GIS)、层次分析法(AHP)以及由与环境、社会和经济限制相关的对冲生成的地图代数。所获得的GIS模型应用于智利的一个地区(比奥比奥地区)作为案例研究,展示了农业废弃物(猪/牛粪和谷物作物废弃物)的能源潜力(205兆瓦时),从而评估其在国家层面(智利)的能源贡献(3.5%)。通过该模型,在确定厌氧共消化厂选址的合适区域时,可以从空间上识别每个因素(环境、经济和社会)的影响。总之,基于GIS的模型在通过沼气生产从农业废弃物中生产能源的重新评估中,为厌氧共消化厂的选址确定了合适的区域。
