“…The primary driver for enabling material circularity is cost, technical feasibility, and government policies [ [103]. According to [12], the companies' barriers for producing and re-using secondary materials are the difficult sales complex, the limited access to sufficient quantity and quality of used materials, the lack of adequate infrastructure for sorting collection [104].…”

The growing concern about climate change and the recognition of the planet’s limits led society to look for alternatives that promote the balance between the natural and the built environment. The circular economy emerges as an alternative to the linear economic model, inspired by natural metabolisms, by circulating resources in continuous loops, where their intrinsic value is maintained and improved. This research proposes a closed-loop strategy in the built environment by studying innovative constructive solutions that aim to find use, value, and inspiration in what is considered waste. A literature review is conducted on the circular design strategies, re-use and recycle typologies, and waste transformation processes. Then, the development of a methodology for qualitative evaluation and selection of re-used and upcycled construction materials from post-consumer waste and by-products is presented and then applied to thirty-five cases of constructive solutions from plastic, wood, paper, steel, aluminium, and agricultural waste. The research reports that the developed framework is adequate. The analysed alternative materials have good environmental performance and can be used as building materials despite their functional limitations, reflecting the enormous potential of waste as a resource for the construction industry.

“…The principal drivers for enabling material circularity are cost-effectiveness, technical feasibility, and institutional public support [103]. According to [12], some obstacles encountered by companies for producing and re-using secondary materials include a difficult sales process, limited quantities and access, and lack of adequate infrastructure for sorting and collection [104].…”

“…Specifications and guidelines for material selection should be improved to reduce uncertainties of the construction contractors, designers, financial investors, and to promote the use of secondary materials rather than primary materials. Taxes on primary materials (e.g., aggregates) applied in most EU Member States and reduced Value Added Tax (VAT) for recycled materials in the Czech Republic [103] are effective measures towards a more sustainable building economy.…”

The rising concern about climate change and other challenges faced by the planet led society to look for different design solutions and approaches towards a more balanced relationship between the built and natural environment. The circular economy is an effective alternative to the linear economic model inspired by natural metabolisms and the circular use of resources. This research explores how innovative strategies can be integrated for evaluating local urban and industrial wastes into sustainable building materials. A literature review is conducted focusing on circular design strategies, re-use, recycle, and waste transformation processes. Then, a methodology for the selection of upcycled and re-used building materials is developed based on Ashby’s method. A total of thirty-five types of partition walls, which include plastic, wood, paper, steel, aluminium, and agricultural wastes, are evaluated using a multi-criteria decision aid (M-MACBETH). Among these solutions, ten types of walls show high-performance thermal and sound isolation, fourteen types are effective for coating, and two exhibit structural reliability. Regardless of their functional limitations, the proposed solutions based on waste materials bear great potential within the construction industry.

“…In fact, the development of transportation infrastructure itself will cause a lot of material consumption. The building materials of these land transportation infrastructures have the potential to be recycled, but this requires the joint efforts of multiple stakeholders (Mhatre et al 2021 ). This is similar to the AEC industry.…”

Compared with the linear economy, the circular economy can solve the contradiction between social development and resource utilization, which has attracted wide attention. Although the relationship between transportation infrastructure and economic development has changed from traditional mode to spatial mode, the spatial effect of transportation infrastructure on regional circular economy is still unclear. By combining the policy changes for developing the circular economy in China, this study constructs a comprehensive index of circular economy development in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). Based on the time and space development of the circular economy in GBA, we analyze the spatial effect of transportation infrastructure on it. The results show that the regional circular economy in GBA has developed, but has not been decoupled from economic development. The development of the regional circular economy presents a positive spatial spillover effect, which is beneficial to the building of the regional recycling market. The improvement of transportation infrastructure has a positive impact on the circular economy of neighboring cities, but it may have the risk of inhibiting the development of the local circular economy. These findings provide policy recommendations for urban planners to coordinate the development of transportation infrastructure and circular economy.
