Sustainable Resource Management in an Agro-Industrial Cluster: A Case Study

Introduction: The challenge of water supply and sustainable energy is crucial for addressing long-term clean water and energy challenges. Moreover, there has been an increase in water and air pollution resulting from the community's activities.   Objective: The objective of this study is to investigate conservation strategies must be enacted to reduce dependency on clean water and energy supplies.   Theoretical Framework: In this topic, the main concepts and theories that underpin the research are presented. Cost reductions, environmental sustainability, and an improved public image for understanding are context of the investigation.   Method: The methodology adopted for this research comprises the case study uses a quantitative descriptive method to identify the estimated potential amount of biogas and water quality produced from tapioca and sago industrial wastewater. Data collection was carried out through the specific methods used, such as interviews, questionnaires, observations,and laboratory testing.   Results and Discussion: The results obtained revealed energy generation from starch wastewater and recycled water from tapioca wastewater. The wastewater was treated in a biogas reactor as primary treatment to reduce the environmental load and produce biogas simultaneously. The wastewater recycling scheme for the tapioca industry, the quality and quantity of treated water recycled.   Research Implications: Biogas production from wastewater reduces energy costs in starch industries. Recycling wastewater saves fresh water daily for starch production. Excess methane can be used for electricity generation or distributed to the community. Implementing anaerobic reactors minimizes environmental pollution. The system boosts sustainability, lowering reliance on external water and energy sources.   Originality/Value: This study contributes to the literature by innovative integration of water recycling and biogas generation in starch industries. First application of CoLAR technology for energy self-sufficiency in tapioca and sago sectors. Demonstrates significant cost savings by reusing treated wastewater in production. Offers a scalable model for sustainable water and energy use in agro-industrial clusters. Contributes to reducing environmental impact through waste-to-energy conversion.
