Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact. Cost of the construction waste amounts 1-3 % of the total project cost. The purpose of this report was to identify causes for construction waste and suggest methods for prevention actions. The aim of this study was to highlight actions and approaches to reduce the quantity and volume of construction waste where possible. Methods used to fulfil the purpose of this thesis were analysis of literature, a case study and interviews. The report was made in collaboration with Nordic Construction Company, NCC, in Uppsala. Zero construction waste in housing industry is not realistic or desirable. The aim should be to optimize material usage based on the projects condition and in a first step try to minimize the work site contribution of construction waste.
