The construction industry releases a great amount of greenhouse gases to the atmosphere, uses loads of resources and generates a lot of waste. These actions are not sustainable, and the industry has therefore created a roadmap of how to become climate neutral until 2045. A few things highlighted in this roadmap is the importance of management and a shift to circular economy, however, previous research has not covered the connection between these in construction projects. This study aims to understand and assess the influence on management when implementing circular economy in construction indu

Resource efficiency and circular economy (CE) has become increasingly relevant to the Swedish construction company NCC in connection to the plans of demolishing the current head office in Stockholm and building a new head office next to it. NCC wants to investigate how to minimize the negative sustainability implications of bringing down a commercial facility well before its life length has expired, through exploring the possibilities of integrating principles of CE in future planning‐and construction processes. This study seeks to understand how the Swedish construction company NCC could work

Circular economy is considered one of the most viable approaches to sustainability and it has gained a lot of traction in recent years. It challenges the linear approach to production and consumption that generates waste and is unsustainable for the planet and future generations. It is crucial to counteract the negative impacts of production on the environment by implementing new and effective business strategies that are compatible with circular economy. Nowadays, manufacturing industries are struggling to make the transition towards circularity because of the intrinsic complexity of adapting

Few have missed out on the fact that the world's carbon dioxide emissions need to be reduced, and the need to switch to a circular economy in order to save earth’s resources is increasingly discussed. In Sweden, the construction sector accounts for more than a third of all generated waste and almost a quarter of all hazardous waste. Therefore, it is necessary to prepare for a transition to a circular economy in the construction industry, where reuse and recycling of materials as well as waste management are highly prioritized issues.

The construction of cities involves the use of land for new spaces and infrastructure. Construction on undeveloped land poses a dilemma on how to deal with the natural resources found on the construction site. Circular economy could provide guidelines on how to harness these resources, so they become products that circulate through as many cycles as possible, therefore decreasing resource consumption and waste. This research aims to explore alternatives to harness the natural materials extracted during the land clearance process of a new urban district: Sollihøgda plussby. Additionally, a new

This study is about finding methods for reusing of packaging from Elekta's product "Leksell Gamma Knife ICON" with Circular Economy as the focus. There is no process for this today. The important thing is the analysis of the entire supply chain from Suppliers to customer and then back to Suppliers to get general ideas about what the problems are and then to draw conclusions for the opportunities that exists. The methods used are analyzes if it is cost-effective and environmentally efficient to transport back packaging to the Suppliers who handle these packaging. Costs for the return process ha

In this I PhD explored the application of the circular economy theory to buildings. I employed methods based on systematic review and meta-analysis, life cycle assessment, case study method and method development. I proposed a method to calculate the circularity of a building. Further, I conceptualized the circular economy building Legacy Living Lab. It resulted that by applying the circular economy to buildings 88% of CO2 emissions can be saved. I produced 5 academic papers.

Idag slängs stora mängder fullt fungerande material inom nyproduktionen i byggbranschen. Detta är ett dolt problem då materialet inte dokumenteras som överblivet material utan i vikt tillsammans med det övriga avfallet. Anledningen till att materialen slängs är den höga tidspressen inom produktionen och att det inte finns en standardiserad process för att ta tillvara på fullt fungerande överblivet material när det inträffar. Kassering av material anses vara lättare, vilket kräver mindre tid och resurser än att med eget initiativ och engagemang ta tillvara på det. Att återanvända material är en

SMEs are an integral part of the Kenyan economy, and SMEs working with a circular economy (CE)can play a crucial role in contributing to sustainable growth and the nation’s sustainable development goals, Vision 2030. However, these SMEs face several challenges. This study aims to contribute to the body of research on CE and SMEs in developing countries, an area that is under-researched. Through the study, the researchers explore and bring to the fore the barriers and enablers experienced by SMEs practising CE in emerging economies.

As volumes of packaging waste are increasing worldwide, the urge to reduce environmental and health impacts caused by this waste stream is leading to rising concern over how it is managed and disposed of. At the same time, resource scarcity and linear consumption patterns have regained attention among business leaders, policy makers and people who have become increasingly aware of the importance of reversing this trend using a sustainable model of growth, also known as ‘sustainable development’. The circular economy is a new paradigm within sustainability that focusses on resource efficiency,

This thesis argues the need for a fundamental shift from the design of products to the design of possessions in the circular economy. Possessions in the circular economy are characterised by interactions resulting in a user-object relationship rather than legalese and differ from the linear economy in terms of their length of use and number of users. Individual users are thus seen as critical actors to enable material circulation in that they take possession and dispossess of products. Two key topics—psychological ownership and contaminated interaction—are explored in detail to fill theoretica

We start with a pre-study of the theories and literature related to circular economy in the developed countries around world. Several case studies are adopted to illustrate the different measures in developing circular economy. Case studies concerning the environmental taxation, the tradable permits and the green certificate system put an emphasis on the economic role of government intervention.

Coal fly ash (CFA) can be regarded as a unique material with the potential to be a showcase waste to illustrate the concept of the circular economy. The application of a processing scheme to power station CFA allows the exploitation of multiple components of the product. The CFA can be separated into low density, carbon, and magnetic concentrates as well as the residual fly ashes. This work contributes to a growing body of research that suggests multi component utilisation of CFA is technologically, environmentally, and economically imperative.

Background: The Circular Economy model came as an alternative to the linear “use and dispose” production system. It argues to promote an economic order that can address the waste of aftermarket goods and a more efficient use of resources and raw materials. It further promises economic gains from a more efficient resource management and extended use of products lifecycle, in conjunction with new employment opportunities that arise as a result of new business models and industrial processes.

The U.N. projects the world population to reach nearly 10 billion people by 2050, which will cause demand for manufactured goods to reach unforeseen levels. In order for us to produce the goods to support an equitable future, the methods in which we manufacture those goods must radically change. The emerging Circular Economy (CE) concept for production systems has promised to drastically increase economic/business value by significantly reducing the world’s resource consumption and negative environmental impacts. However, CE is inherently limited because of its emphasis on recycling and reuse

By analyzing the discourse in states official roadmaps towards circular economy, this study forms an understanding for what motivates a transition. The findings show that the possibilities for economic gains and the creation of new markets are the main purpose to change. In addition to that, whenever the survivability of humanity and the environment was arguments for a change, it in almost all cases came back to the economical ou
