Core Viewpoint - The establishment of Shandong's first independent sludge incineration project in Qingdao transforms sludge from a burden into a resource, generating economic and environmental benefits through energy self-sufficiency and efficient waste management [2][4]. Group 1: Project Overview - The sludge incineration project can process 600 tons of sludge with an 80% moisture content daily, addressing the previous need to transport 30% of the sludge out of the city for processing [2]. - The project achieves 100% local digestion and harmless disposal of sludge, eliminating high transportation costs and associated safety risks [2]. Group 2: Operational Efficiency - The project reduces energy consumption by over 30% by utilizing self-sustaining combustion, where over 80% of the heat generated is reused for drying incoming wet sludge [2]. - The overall operational costs are further reduced by 10% through a synergistic approach with neighboring facilities, utilizing biogas and excess wastewater for energy and water needs [3]. Group 3: Environmental Impact - The project effectively addresses odor and pollution issues by collecting and incinerating all foul gases at high temperatures, ensuring no harmful emissions [3]. - The final product of the incineration process is a stable powder with over 99% ash content, significantly reducing the volume of sludge and eliminating potential threats to land and water sources [3]. Group 4: Broader Implications - The project serves as a model for creating a "waste-free park," integrating sludge disposal, waste management, wastewater treatment, and energy recovery into a closed-loop system, showcasing a sustainable path for urban waste management [4].
