What is an eco-industrial park and how does it relate to industrial ecology?

• A. A park for recreational industry workers.
• B. An industrial area with disorganized waste.
• C. A park dedicated to ecologically unsound production.
• D. A cluster of firms that collaborate to share resources and minimize waste; a practical implementation of industrial ecology.

Answer: (D)

An eco-industrial park is a cluster of neighboring firms that collaborate to share resources and minimize waste, turning outputs from one process into inputs for another and coordinating energy, water, and material flows. This setup is a practical reflection of industrial ecology, which looks at how industrial systems can operate more like natural ecosystems by closing material loops and improving resource efficiency. In such parks, waste or by-products from one company become inputs for another, reducing environmental impact and often cutting costs. For example, heat or steam from one facility can supply energy to others, and waste streams can be redirected for reuse. It’s not about recreation, disorganization, or unsound production—it's about coordinated, resource-efficient cooperation that embodies the ideas of industrial ecology.
