Summary
China faces significant challenges in construction and demolition (C&D) waste recycling due to ineffective policies and poor waste management practices. Addressing these issues is crucial for sustainable development and environmental protection in the country.
Area of Science:
- Environmental Science
- Civil Engineering
- Waste Management
Background:
- China generates substantial construction and demolition (C&D) waste due to rapid industrial development.
- Existing policies for C&D waste recycling in China are not effectively implemented, leaving many cities with significant waste accumulation.
- Effective C&D waste management is essential for sustainable urban development.
Purpose of the Study:
- To identify and analyze the key challenges hindering the development of C&D waste management and recycling in China.
- To provide practical recommendations for improving C&D waste recycling policies and practices.
Main Methods:
- Conducted site visits to 10 C&D waste recycling plants across 10 major Chinese cities.
- Performed interviews with 25 industry practitioners to gather insights on operational challenges.
- Synthesized findings to identify systemic issues in C&D waste management.
Main Results:
- Identified eight major challenges: unstable waste sources, lack of subsidies, insufficient focus on waste minimization in design, absence of on-site sorting regulations, unregulated landfilling, poor inter-departmental coordination, inaccurate waste estimation, and lack of effective waste tracing.
- Highlighted the gap between policy formulation and practical execution in China's C&D waste sector.
Conclusions:
- Effective C&D waste management in China requires addressing systemic challenges related to policy implementation, economic incentives, regulatory frameworks, and inter-agency coordination.
- The study provides a foundation for policymakers and researchers to develop targeted strategies for improving C&D waste recycling in China and other rapidly developing economies.

01:25Deleterious Substances in Aggregate
406
Deleterious substances in aggregates can be detrimental to the quality and durability of concrete. These substances include organic impurities like loam, which interfere with cement hydration and are usually present in the sand. These prevent a good bond between aggregate and cement paste. Organic impurities can be detected using the colorimetric test, where the darkness of a solution after agitation indicates the level of organic content.

01:29Aggregates Classification
591
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...
