Implementation of 3R principle in construction and demolition waste management

Abstract

Building and demolition of structures are common in developing nations owing to fast urbanization taking place. These operations produce an enormous quantity of waste products that are detrimental to the environment, requiring an efficient method of waste management. Construction and Demolition Waste Management (C and DWM) methods frequently embrace the 3R (Reduce, Reuse, Recycle) principle for suitable waste management in construction sites. Managing different waste in separate areas of the industry seems very important nowadays. Most contemporary Western counties around the globe set separate laws to reduce and handle the quantity of waste in various areas of their industries as well. However, waste manufacturing is inevitable in the building sector, and no building site is less waste. Different kinds of waste in building sites can cause infinite social and environmental issues. It seems crystal clear that there is a huge need for waste management in such a scenario. A fresh idea on building waste management has been suggested in latest years is "3R” concept, which is based on three key waste management concepts such as reuse, recycle and reduce. Waste management was discussed in the introduction chapter. Then Construction type of waste was evaluated after Managing was reviewed, then various kinds of waste followed by how to do energy recovery through "3R” principles and lastly how to execute energy recovery through the "3R” principles mentioned. Hopefully the content of this article will benefit various individuals in charge of building projects.
