Byggmaterialens livscykel : En analys om hur miljön påverkas under ett byggprojekt

Sammanfattning: Problem background: During a construction project, the environment is negatively affected due to all construction waste that occurs. Even during the manufacture of building materials, the environment is affected. Construction waste in Sweden is about 31 percent, it is quite high, but they are constantly trying to reduce construction waste and the environmental impact that the construction sector is responsible for. The construction waste that takes place has a direct connection to building materials, which also has a direct connection to the carbon dioxide emission in the production of these building materials. Therefore, in this work we have addressed these three points that focus on the environmental impact that the construction industry has in a construction project. The purpose of the work is to investigate how the construction industry affects the environment. Because it is a complicated industry where a lot happens. For example, there are several different types of transport both from and to the construction site that leads to increased carbon dioxide emissions. To reduce construction waste, you must have the knowledge as to know why construction waste occurs and be able to apply the waste hierarchy during a construction project for reduced environmental impact. The methodology for completing this work was due to various scientific articles and literature studies used, via Mälardalens University's library database. In addition, some interviews were conducted that helped strengthen and complete the work. The interviews provided different views and perspectives and explained in detail how construction waste is handled during a construction project. The survey provided a better insight into how this is done, handled and what solutions are available to reduce the construction sector's environmental impact during a construction project. The end results of the work showed that there are some methods you can use to reduce the environmental impact that the construction industry has today. With these methods, it is not only the environment that has a positive effect but also the construction company because it leads to lower costs and more efficient construction methods. The results also showed that the construction industry is a complicated industry where a lot affects each other and that they always try to reduce their environmental impact by constantly striving for their environmental goals. The Conclusions of the work is that the environment affects the construction industry in different ways. Everyone involved is trying to reduce their influence, but there are some challenges that exists and should be addressed. The work highlights the problem and alternative solutions that the construction industry can use to reduce their environmental impact.
