Framtidens byggproduktion: deponifri : En kartläggning av framgångsfaktorer för minskat byggavfall till deponi inom nyproduktion

Sammanfattning: This technical report contains a study of the construction industries work regarding landfill waste. More specifically Sweden’s and the company Skanska’s development to prevent landfill and fulfill an ecofriendly society. The construction companies in Sweden are accountable for over a third of the country’s total waste and are prioritized to improve their statistics. Skanska have a goal to reach zero percent landfill waste, therefor should all the construction material be able to reuse or recycle. The purpose of this study is to find the causes and background of the landfill waste and to identify the factors of success. The goal is to give recommendations to Skanska on how they progressively can phase out landfill waste. The content of the report is built from a background part where the general challenge and goals is explained. Thereafter are the methods for information acquisition, interview study and literature study explained along with some typical landfill material and how it can be reused or recycled. A few projects are listed under chapter four to give the reader an understanding for what the authors have been looking at. Lastly the report will take the reader through the study’s results, discussion and recommendations. The results show that some recycling methods are available for the fractions which usually ends up as landfill. But the requirements for recycling and reuse are often too hard to fulfill in the construction industries. The interviews show that a high commitment is necessary for a highly qualified work with the landfill waste. Future projects are recommended to early on identify material that easily becomes landfill and avoid them as much as possible. Use smaller bins where there is less space and work continently with waste plans.
