The adoption of appropriate waste management strategy has been considered as a lasting solution to part of the environmental problems facing Anambra State of Nigeria. Implementation of spatial information technologies such as Remote Sensing (RS) and Geographic Information System (GIS) in addressing the issue of waste management has been identified as an appropriate technology. The limitations of the use of GIS alone or only location mathematical models in effective suitability analysis has been observed by many researchers, therefore this study adopted the integration of geospatial technology with Set Cover Location Model (SCLM) and facility location allocation modelling as a holistic approach to the problem. The result of the study shows that a minimum of three biogas processing plants is needed to maximally process all the wastes in the study area. The output of the allocation and location model shows that a processing plant with about 5.6 Tons, 1.7 Tons and 57 Tons capacity is best located at Ajali, Ihiala and Abagana towns respectively in the study area. It is recommended that strategic waste management approach as used in this study will be a veritable tool for energy solution in the study area. (C) 2019 Elsevier Ltd. All rights reserved.
