| Title | Eco-Efficiency Of Construction And Demolition Waste Recycling In Chongqing, China |

| Abstract | Ongoing urbanization along with increased regeneration of the obsolete city centres makes the recycling of Construction and Demolition Waste (CDW) an ever hot topic to realize China's circular economy strategy in its construction industry. However, the current recycling rate of CDW is only 5% in the country and the recycling industry is in its infant stage. How to recycle the CDW in a more cost effective and environmentally beneficial way, given the opportunity of the underdeveloped CDW recycling system in China, is a key issue to be investigated at this moment. From a life cycle perspective, eco-efficiency analysis is used in this study to systematically evaluate the potential pros and cons for developing the different types of CDW treatment and recycling systems to be developed in Chongqing. Nowadays, two forces are driving the development of the CDW recycling industry in China: one is from grass-root - e.g. around 20 small private recycling plants have been established in Chongqing in the last decade, and another is from top-down - e.g. billions of Chinese RMB have been spent to build a group of state-owned large CDW recycling centres. The case study shows, properly designed, the eco-efficiency analysis is able to identify the hot spots and trade-offs between economy and environment systems. |
