Digital platforms to promote recycling

There is a global consensus that the countries of the world must work to ensure a sustainable future for the next generations and Sweden is no exception. The construction sector is responsible for about a third of the generated waste in Sweden. To be able to impact and reduce the current global footprint, the sector needs to aim for a change. One of the ways to promote a sustainable construction sector is to increase the reuse of building materials in current projects. The companies use digital platforms to facilitate the coordination of this process to increase the effectiveness of the project. The goal of this thesis is to explore the conditions that are needed for the building sector to be able to implement reused building materials by using digital platforms. The digital platforms are used as tools to expand and promote reuse of former building materials in projects by facilitate the selling and the purchase process. This study is primarily centered upon the digital platforms CCBuild, Palats, Loopfront and BuildID. The methodology of this study is based on a literature study, interviews and a case study in which the district of Hugin is used as a reference. In this study the company Vasakronan is also introduced because of their experice with digital platforms in their projects. Vasakronan is currently working with the renovation project of the Hugin district located in the center of Uppsala. Their partner in this project is Byggstyrning and they are both to their greatest extent working to reduce waste by using reused building materials from the former parts of the building. The results of this case study indicate that there are areas that need an improvement. It also points out the need for a software program that can register data from Excel files directly into the platforms. To increase the quantity of reused material in projects where digital platforms are used, there is a need to focus on the following points: tools for inventory, increase marketing, interoperability of the digital platforms, but also implementation of standards to make it possible to connect to BIM-models. The result shows the challenges with implementation of reused building materials in projects according to the following points: the customers are the key decision makers, building materials lose their original quality, but also the lack of knowledge
