Abstract
The main focus of this study is to evaluate possible alternatives for organic waste disposal and compare different waste management options in order to determine the most appropriate disposal method for bio-wastes in sustainable waste management. With increasing urbanization and population growth, managing bio-wastes has become critical for environmentally friendly solutions. Traditional landfill methods contribute to global warming through greenhouse gas emissions, while methods such as composting, biogas production, bokashi, vermicomposting, and biochar production, which offer bio-based product generation and renewable energy potential, present sustainable alternatives. In this research, the Analytic Hierarchy Process (AHP), a multi-criteria decision-making method, was used to evaluate these methods based on criteria such as investment costs, operating costs, carbon footprint, energy recovery, and contributions to agricultural health. The AHP results indicate that biogas is the most suitable method for bio-wastes management. Despite high initial investment and operating costs, biogas is highlighted for its significant carbon footprint reduction and high energy efficiency. Biochar and compost rank second and third, respectively, followed by bokashi and vermicompost among the evaluated options. These findings show that biogas plants around the world have significant potential as a renewable energy source and can help reduce dependence on external energy sources. This study evaluates bio-waste disposal methods with the Analytic Hierarchy Process (AHP).
期刊介绍:
Integrated Environmental Assessment and Management (IEAM) publishes the science underpinning environmental decision making and problem solving. Papers submitted to IEAM must link science and technical innovations to vexing regional or global environmental issues in one or more of the following core areas:
Science-informed regulation, policy, and decision making
Health and ecological risk and impact assessment
Restoration and management of damaged ecosystems
Sustaining ecosystems
Managing large-scale environmental change
Papers published in these broad fields of study are connected by an array of interdisciplinary engineering, management, and scientific themes, which collectively reflect the interconnectedness of the scientific, social, and environmental challenges facing our modern global society:
Methods for environmental quality assessment; forecasting across a number of ecosystem uses and challenges (systems-based, cost-benefit, ecosystem services, etc.); measuring or predicting ecosystem change and adaptation
Approaches that connect policy and management tools; harmonize national and international environmental regulation; merge human well-being with ecological management; develop and sustain the function of ecosystems; conceptualize, model and apply concepts of spatial and regional sustainability
Assessment and management frameworks that incorporate conservation, life cycle, restoration, and sustainability; considerations for climate-induced adaptation, change and consequences, and vulnerability
Environmental management applications using risk-based approaches; considerations for protecting and fostering biodiversity, as well as enhancement or protection of ecosystem services and resiliency.
