FASADSPILL - PUTS VÄCK : En kartläggning av putsprocessen och dess avfallsmängder

Sammanfattning: The Construction sector is the industry that generates the second most waste afterthe mining industry in Sweden. Therefore, reducing waste is a primary issue for thesector. JM AB have a new environmental goal to reduce waste. The companyseparated their waste into fractions in order to study them individually. This reportis the result of a survey of the waste fraction facade plaster. The investigation ismade for thick plaster that is "scrubbed" with a board with nails in order to get theproper appearance (Swedish: "rivputs"). The purpose of the study is to see how much waste the plaster process representsand what it will take to reduce this fraction of the waste. Interviews, study visits anda literature study was made collect information about the process. Calculations shows that about 20% of all plaster materials are thrown away. Animportant aspect is that approximately 18% of the plaster materials is "scrubbedaway" to get the right structure of the facade. Therefore, a new material or a newmethod to apply the plaster would be required to eliminate this 18% of the waste. About 2% of all plaster material turns into waste when cleaning the pipe that is usedto apply the plaster on the wall. Shortening of the pipe would reduce waste andaffect the method for the labors who work with plaster at the construction site. Toimplement such a change at JM AB, an investment is required.
