In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed. Furthermore the results for the two products and their life cycles are described. The production areas in Italy and Czech Republic are described. The areas for extracting the materials, Ukraine and Czech Republic, and the different types of clay being used are presented. The impact on workers and areas are described and analyzed and hazardous processes such as glazing are investigated. The analysis mainly touches which processes or materials that have the biggest negative effect on the environment, such as extracting of raw materials, and also a critical analysis of the information sources being used, since they mostly consists of interviews and fieldtrips. The report concludes with an analysis of both the results and the use of Sustainability Life Cycle Assessments. It is concluded that the different tiles can be used in the production still meeting Riksbyggen’s sustainability conditions. At last suggestions for further studies and information dedicated to Riksbyggen are presented.
