ABSTRACT
While technical literature extensively documents the potential of synergistic utilization of construction demolition waste (CDW) and agricultural waste as cement alternatives, understanding of country-specific implementation contexts remains fragmented. This qualitative study examines how national institutional frameworks, policy discourses, and industry practices shape opportunities for sustainable waste-to-cement strategies in the United Kingdom and China through comprehensive analysis of secondary sources. Utilizing document analysis, this research reveals distinct implementation paradigms that reflect contrasting approaches to construction innovation, environmental governance, and industrial development. The UK demonstrates a regulatory-driven paradigm characterized by comprehensive standards, stakeholder consultation, and evidence-based implementation, while China exhibits a development-oriented paradigm emphasizing rapid scaling, policy experimentation, and adaptive management. The result analysis further reveals how these paradigms create fundamentally different opportunity structures for waste utilization. The UK‘s approach favours high-specification, niche applications with extensive validation requirements, while China's paradigm enables large-scale deployment through pilot programs and iterative improvement.
