The consideration of environmental issues is becoming increasingly important in development and architecture. A program for sustainable development in the 21st century, Agenda 21, was agreed at the United Nation Conference on “The Environment and development” in Rio de Janeiro in 1992, to consider action for improving the environmental situation.
The generation of construction and demolition (C&D) waste is one of the major issues that received little attention in sustainable structures. The construction industry in most countries generate a huge quantity of C&d waste that is either transferred to public fill areas for reclamation and site formation use or disposed at landfills. Some of that waste may be hazardous, harm human health and impact on regional and global environment. Therefore, Waste minimization needs to become a goal in project development and design to consider seriously the issues of waste. So the purpose of this study are ;:(1) to review the construction and demolition wastes in building industry and the hazardous wastes which can occur from waste materials in construction sites, (2) to discuss the features of value management concept for minimizing the waste during VE workshop plan, and (3) proposed guidelines for waste management for designers and all parties involved in building process.
The main conclusion of this study insured the need to integrate of the 4Rs golden Rule (Reduce, Reuse, Recycle, Recover and disposal) to establish a methodology that can apply in waste management plan to improve waste materials efficiency and protection of environment |
