Recycling of construction waste as one of the aspects of sustainable construction

Nalewajko M.

144--155

The article presents the concept of using construction waste as an alternative to natural aggregates in sustainable construction. Due to the fact that the quantity of concrete produced per year is very large, its complete processing would make it possible to produce large quantities of secondary aggregate. Reuse of recovered debris involves the need to recycle it. Therefore, technologies should be implemented to allow the use of raw materials Recovered and waste treatment should ensure that the highest quality raw material is obtained. Contemporary technologies and knowledge allow for the development of a method that will allow for complete debris remediation as well as the cost reduction of the entire technological process. It is extremely important from the point of view of environmental protection and economic account.

Cellular concrete – the material of sustainable construction

About 4 million Mg of construction waste is produced in Poland annually. According to the record of a “new” Directive (Directive of the European Parliament and the Council 2008/98/EC of 19 November 2008 on waste and repealing certain directives), preparation to reuse, recycle and other methods of recovery for construction and demolition waste should be increased to the minimum weight of 70% until 2020. In sustainable construction it is preferable to use the products which, after the usage period, can be subject to disposal with a special emphasis on recycling which, in addition to environmental benefits, generates tangible economic benefits. Recycling of building materials is also an important source of raw materials used as the surface foundation for the production of other construction materials or road works. Cellular concrete is nowadays considered to be a “natural” or “environmentally friendly” material. The article discusses the housing sector altogether with the market of construction materials as well as presents the characteristics of cellular concrete - an ecological construction material.
