This chapter will study the proliferation of architectural follies that use recycled or recyclable materials in a move to promote better practices in waste and recycling. Given the slow uptake of this impetus in the architectural world proper, the text will investigate the obstacles in engaging in materially sustainable practices in the construction industry as well as case studies for rethinking currently problematic materials. However, while some improvements have been made in the construction industry's use of recycled materials, the industry often dismisses the afterlife of materials used throughout the process. What are the motivations of the industry and how can we incentivize circular thinking in an industry that produces hundreds of millions of tons of waste per year in the US?

Printing Techniques

The construction industry has embraced digitisation and industrialisation in response to the need to increase its productivity, optimise material consumption and improve workmanship. Additive manufacturing (AM), more widely known as 3D printing, has driven substantial progress in these respects in other industries, and a number of national and international projects have helped to introduce the technique to the construction industry. As with other innovative processes not covered by uniform standards, appropriate assessments and testing methodologies to control the quality of the 3D-printed end products, while not obligatory, are advisable. This article shows that regulation is not an obstacle to the use of an innovative product, such as 3D printing, by proposing quality-control tests and an assessment methodology, in the understanding that standardisation ensures the viability of a technology. The information, including the methods and results, is based on the authors’ experiences in the development of three research projects pertaining to 3D printing. This paper also discusses whether the performance of the materials used in 3D printing could be superior to traditional ones.

Since the 1980s, a wide range of physical and non-physical interventions, including megaprojects and flagships to small-scale projects and temporary usage, are prescribed as catalysts for urban regeneration. The strategy of utilizing urban catalysts as a tool for urban renewal has been encouraging by many city authorities through specific subsidization and privileges. However, there is no correct and precise definition of the tools and the qualities they should provide as their impacts. Besides, some criticize the catalytic projects due to their unsustainable, unjust, and destructive consequences.  This paper intends to provide a more comprehensive definition of urban catalysts by reviewing the existing literature. The research has been done through a deductive and inductive approach to reach the principal dimensions and criteria for catalytic projects. It uses a series of potential projects and interventions in the City of Tehran (16 projects and practices) as case studies to check the dimensions and criteria and the quality of each project as catalysts. The quality of the selected case studies was ranked through expert judgment and checklist method. The findings show the cases' rank on how their catalytic impacts comply with sustainable development goals. According to the results, seven criteria (environmental sustainability, context-based development, pattern making, branding, social quality of life, economic prosperity, and market adaptability) are essential to ensure the sustainability of catalytic impacts of catalyst projects.

Abstract Similar to other fields, the construction industry tends to constantly evolve. There is an increasing demand for the construction of new buildings regarding the speed of the construction process, economy, and minimization of the negative effects on the environment, i.e. sustainability. These requirements can be met by using prefabrication for this construction. Modular construction represents one of the prefabrication technologies that is becoming increasingly popular worldwide. The topic of this article is the use of modular construction, even from the sustainability point of view. There is a basic overview of modular construction, its history in the construction field, an overview of the materials used, and the possibilities of its implementation. Furthermore, this article provides an overview of the advantages and disadvantages of modular construction. The advantages are listed in terms of quality, economy, time, and ecology as well as in terms of construction flexibility and work safety, both during production and assembly on the construction site. The disadvantages of modular construction discussed in this article are the complicated transportation of modules, demanding coordination of production and construction, the requirement for detailed construction planning, and the non-acceptance of this construction technology by the general, and sometimes professional public. This article also deals with the comparison of modular construction technology with conventional construction technologies. It points out the possibility of reusing materials from disassembled modular buildings. It also points out the ways to control and mitigate the impact of modular construction on the environment throughout the life cycle of modular building. Only after a thorough analysis of these aspects of modular construction, is it possible to explore other ways to further increase the efficiency of this technology in all directions and also to make even better use of its environmental impact minimization potential.
