“…A total mass of 36.3 tonnes was used in L3, including steel (61%) and timber (26%), of which 58% is disassemblable and technically reusable infinite times due to the resiliency of that material and the accurate design for disassembly (see Figure 3). Conversely, the reuse of materials such as timber is assumed to be limited to three times, because of material degradation and the use of potentially toxic chemical treatments such as termite proofing [42]. This section is organised into five subsections based on material categorisation: steel, timber, cladding and floor covering, insulation and glazing, and waterproofing and plumbing details.…”

“…Typically, lightweight steel structured prefabricated buildings enable substantial material saving over traditional construction typologies, such as concrete and brick buildings [18,42,57]. Designing within parameters that allow parts of a building to be transported considerably increases the likelihood that they will not have to be demolished [58].…”

“…Concerning buildings, designers can achieve life extension by increasing the buildings' material quality and resilience by creating flexible spaces [8]. Material resilience is described as a structure that must be robust enough to withstand the forces imposed on it through the disassembly and relocation process [42]. In this context, building relocation can also enable material reduction, preventing both demolition waste and the use of materials to reconstruct a building elsewhere [18].…”

This study investigates the interconnection methods used to create a circular economy building featuring modularity and designed for disassembly and relocation. Designing modular buildings for disassembly and reuse can decrease waste production and material depletion, in line with the circular economy framework. Disassemblable buildings require connections to be easily accessible. Visible connections may be unpopular features; however, concealing these, yet leaving these accessible, presents a substantial design challenge. This study demonstrates solutions to this challenge by analyzing a purposely designed case study: the Legacy Living Lab. The challenges of disguising and sealing, such as by waterproofing, two types of connections are analysed: structural and non-structural. This study details the materials and connections used across the two analyzed connection types and compares the weights and reusability of components. Thus, a necessary case study is provided for practitioners to advance circular economy theory in the building industry. Notably, all connections in the Legacy Living Lab can be easily accessed with standard building tools, facilitating its disassembly and fostering component reusability.

In recent years, the manufacturing sector is going through a major transformation, as reflected in the concept of Industry 4.0 and digital transformation. The urge for such transformation is intensified when we consider the growing societal demands for sustainability. The notion of sustainable manufacturing has emerged as a result of this trend. Additionally, industries and the whole society face the challenges of an increasing number of disruptive events, either natural or human-caused, that can severely affect the normal operation of systems. Furthermore, the growing interconnectivity between organizations, people, and physical systems, supported by recent developments in information and communication technologies, highlights the important role that collaborative networks can play in the digital transformation processes. As such, this article analyses potential synergies between the areas of sustainable and resilient manufacturing and collaborative networks. The work also discusses how the responsibility for the various facets of sustainability can be distributed among the multiple entities involved in manufacturing. The study is based on a literature survey, complemented with the experience gained from various research projects and related initiatives in the area, and is organized according to various dimensions of Industry 4.0. A brief review of proposed approaches and indicators for measuring sustainability from the networked manufacturing perspective is also included. Finally, a set of key research challenges are identified to complement strategic research agendas in manufacturing.

“…O'Grady [33] introduced the 3DR method (design, disassemblability and deconstructability) which was used to prepare a circular economy index by considering the design stage, disassembly, deconstruction, resilience of the buildings' structural fabric and finishing components. The potential second life of building materials, reuse, recycling, downcycling or disposal and the difficulty of separating materials from each other was the main influence in preparing the index [33].…”

The Circular Economy - Recent Advances in Sustainable Waste Management

View full text Add to dashboard Cite

This chapter is centred on waste management in buildings. It discusses the principles of applying circular economy in buildings toward resource efficiency with regard to the building sector. The study investigates a series of building assessments and reviews different aspects of energy efficiency as it relates to circular economy in buildings. It recommends the best practices to ensure the reuse and recycling of building components during and after the life of a building. The world is experiencing huge resource depletion and it is eminent to research the waste management practices in the building industry, Circular Economy offers major interventions in buildings which are explored in this chapter, another aspect of the discussion in this chapter is the design for disassembly and design for recycling under the concepts of circular economy.
