Abstract [eng] |
Large amounts of construction and demolition waste are generated in Europe each year. It is estimated that the construction sector alone generates around 820 million tons of waste per year in Europe. Lithuania generates about 1 million tons of construction and demolition waste, of which mixed construction and demolition waste is still a significant (about 30%) part of the construction waste stream (17 09 04). Most of the mixed construction and demolition waste entering landfills should be waste that is no longer suitable for recycling. However, due to inadequate sorting, plenty of secondary raw materials, along with mixed CDWs, gets to landfills. Nowadays, in terms of global warming potential CDW reuse and recycling is the most ecological CDW management techniques. In order to be able to reuse or recycle CDW, sorting plays an important role. The management of construction and demolition waste could be significantly improved by developing environmentally friendly and cost-effective CDW recycling, as well as by developing the separation of clean secondary raw materials from the mixed CDW stream. |
