From Coal to Rose: Sustainable Development in Zichuan District, Shandong Province

This case study examines the innovative approach taken by Zichuan District in Shandong Province, China, to achieve sustainable development in a resource-depleted area through the use of abandoned mines. The district leverages its legacy mining sites to build a green economy, focusing on renewable energy integration and high-value industries.

Background
Zichuan District has a century-long history of coal mining, leading to severe environmental degradation. With over 195 closed mines and 64 abandoned sites, the district faces challenges like land contamination, water table depletion, and persistent pollution. This has depressed the economy, with high energy consumption in traditional industries, prompting a need for green transformation to align with global trends away from fossil fuels.

Key Actions
The district initiated a pilot project at Daqiu Mountain, known as "Energy + Industry" integrated transformation. This involves developing a comprehensive system:

• Energy Component: Utilizing abandoned mines for renewable energy, including solar farms (photovoltaic systems), distributed pumped hydro storage, and heat pumps, to create a diverse energy mix.
• Economic Component: Establishing a rose flower industry chain by building greenhouses and integrating with local resources, reducing production costs and creating jobs. Innovations include water reuse and waste heat utilization to enhance efficiency.

Benefits
The project delivers significant environmental, economic, and social returns:

• Environmental: Achieves substantial CO2 reductions (e.g., 9,400 tons annually) and restores degraded land through ecological measures.
• Economic: Generates high profits (over 6 million yuan annually), creates employment opportunities, and stimulates regional growth by integrating second and third industries.
• Social: Provides jobs for local residents, particularly former miners, and improves quality of life through community engagement.

Experience and Lessons
The Zichuan model offers valuable insights for other abandoned mining areas:

• Coordinated Planning: Emphasizes system-wide approaches, involving government, academia, and business for holistic project management.
• Context-Specific Innovation: Turns former mining sites into hubs for green innovation, using technological advancements and local resources.
• Collaborative Model: Involves partnerships among stakeholders, including government bodies, research institutions, financing entities, and operators, fostering sustainable scaling.
• Replicability: With plans to replicate the model across Zichuan, the approach could support broader regional transitions, making it a template for resource-depleted cities worldwide.
