Nyttjande av ofrörbrukat byggmaterial : En rapport åt Peab Jönköping

Sammanfattning: This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away. When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material. The costs for the storage area was however relatively high, large savings are therefore needed. These savings are very difficult or actually almost impossible to calculate because it is very difficult to know how much material that really is usable of the total waste. The savings can be estimated, however with low reliability. Hence, the proposal seems very expensive since the savings are not being able to cover the costs. If the incomes were known from the beginning it would be easier to properly design a proposal. Another way is to test the proposal at a smaller range first to better be able to calculate the savings. The decrease of environmental influence and other impacts from the proposal are hard to show with figures and it is difficult to estimate how much the storage area will cost. Based on this, Peab are therefore presently recommended not to take this risk. With this knowledge at hand an alternative proposal was designed. This proposal suggested a development of Peab’s already existing storage area utilizing the same resources as today. If this is properly realized, the environmental influence will be reduced and Peab Jönköping’s economy will be improved.
