Abstract
Sewage sludge management in Palestine faces considerable environmental, economic, and public health challenges due to fragmented governance, technological limitations, and social barriers. The research aims to understand the current state of practice in sludge management in Palestine, assess the sludge's potential for agricultural and energy uses, and determine the possibilities of value-added processing. It also aims to assess the environmental and public health risks associated with the current management practices. By analyzing these factors, the study aims to enhance sludge management and promote resource utilization.
The research employed the Governance Assessment Tool (GAT) to evaluate governance structures' effectiveness, coherence, and responsiveness. Data collection included a comprehensive review of the available literature, such as policies, standards, and related literature. Also, stakeholder interviews were conducted, and case studies of wastewater treatment plants in Nablus, Jericho, and Al-Bireh were conducted, along with an overview of the countries in the region.
The study also included the best global practices and innovative technologies such as biogas recovery, composting, and hydrothermal carbonization to identify suitable solutions for the local context.
The findings reveal some challenges in governance, technology, and public perception. Current governance frameworks are fragmented, with inadequate coordination and enforcement of regulations. Technical issues, including high sludge moisture content and the absence of efficient disposal pathways, also raise operational costs and environmental risks. Sociocultural and behavioral barriers to sludge reuse, including the perception of farmers as opposed to it, also restrict progress. However, the study shows potential for resource recovery, including biogas production and composting, that can decrease reliance on landfills and be compatible with circular economic approaches.
To address these challenges, a multifaceted, comprehensive approach is needed. Recommendations include proposing unified governance systems, selecting and implementing advanced treatment technologies, and enhancing stakeholder engagement. Increasing biogas recovery and composting activities is a way of enhancing resource utilization, decreasing costs, and decreasing adverse environmental effects. Public education campaigns and targeted stakeholder engagement are essential to removing socio-cultural barriers and encouraging acceptance of new solutions.
