Adopting a circular vision in the construction industry

Abstract

Over the past decade topics concerning the climate and how to preserve it have become increasingly relevant. Due to its make-use-dispose mentality as well as the slow adaptation of new technologies, the construction sector forms one of the worst climate polluters, waste producers as well as natural resource extractors. This thesis will offer alternative methods of construction which will allow the sector to change its course to a more circular, make-use-reuse, direction. These methods will be presented and evaluated according to their advantages, disadvantages as well as financial aspects. The data for this research is collected through a complex literature review offering insight on various circular concepts as well as presenting case studies which showcase different methods in practice.

The thesis begins by discussing the current methods utilised in construction today and the possible sustainability challenges related to them. This is followed by introducing the concept of circularity and assessing its compatibility with the building sector. Some possible techniques for adding circularity into construction will be presented along with relevant case studies. In total, five cases concerning four different circular methods, design for disassembly, usage of recycled building materials, building repurposing and material passports, will be brought forward.

After assessing the information included in this research, it can be stated that there are multiple ways of increasing circularity in construction and all of the methods presented lead to numerous environmental benefits, such as minimisation of waste production and natural resource exploitation. The concepts still require further developments and possible endorsement from the officials in order to push them into new standards in the construction business.
