Composition and Characteristics of Construction Waste

Composition and Characteristics of Construction Waste

Aug 09 2020 The waste generated from the construction industry is commonly called as Construction Demolition Waste or CD waste Most of the waste materials in construction industries are nonbiodegradable and inert materials Construction waste materials are heavy dense bulky in characteristics and it needs more storage space and cannot follow standard waste disposal methods construction waste for several ongoing residential construction projects in Miri City Sarawak Malaysia are presented A database of information concerning the quantification of local construction waste was developed in addition to current construction waste management practices Key words Construction waste Waste quantification Composition
