| What is Industrial Ecology? | Industrial ecology is the study of the means by which humanity can deliberately and rationally approach and maintain a desirable carrying capacity, given continued economic, cultural, and technological innovation. The concept requires that an industrial system be viewed not in isolation from its surrounding systems but in concert with them. It is a systems view in which one seeks to optimize the total materials cycle from virgin material, to finished product, to component, to product, to obsolete product, and to ultimate disposal. Factors to be optimized include resources, energy, and capital. |
| Industrial symbiosis | Industrial symbiosis describes co-dependent relationship between industries. |
| Integrated Waste Management Hierarchy | 1. Source Reduction and reusing 2. Recycling and composting 3. Energy Recovery 4. Landilling |
| Life-cycle assessment: Cradle-to-gate | Cycle from raw materials to product sale. Materials balance around a process. |
| Life-cycle assessment: Cradle-to-grave | Cycle from raw materials to process, consumer use and disposal. Materials balance around a product. |
| Life-cycle assessment: Cradle-to-cradle | Unlimited materials recycling and no waste production. |
