Abstract

In this paper waste management of construction industry, its impacts to environment and recycling methods are studied for city of Izmir, Turkey. The construction industry is one of the largest sectors of the world economy, especially in developing countries with increasing population. A large amount of construction, renovation and demolition activities take place especially in residential buildings, roads, bridges, utilities due to many of the structures mentioned become old. These demolishing and renovation activities create in large volumes of construction and demolition waste (CDW) that should be managed, recycled and disposed. In addition to management of CDW, there are also environmental effects of production of construction materials such as cement and aggregates. Stone mining or quarries crushed stone is the most common method to produce construction materials (aggregates, sand, and cement). The stone pits are operated for long time. During operation, the nature is altered; rehabilitation of pits may be done after pits are closed. Besides, construction and demolishing waste are needed to be stored in large areas. All these mentioned activities effect the environment. Thus, recycling solid materials of CDW provides saving both by reduction use of new material and management costs of waste materials.
