The demolition process raises several primary environmental concerns. One of the most significant issues is the generation of construction and demolition (C&D) waste. This waste often ends up in landfills, contributing to environmental pollution and taking up valuable space. Additionally, the release of dust, debris, and hazardous materials during demolition can have adverse effects on air and water quality. The use of heavy machinery and equipment in the demolition process also contributes to noise pollution and consumes significant amounts of energy.
The demolition process contributes to embodied energy consumption in various ways. Firstly, the energy used in the initial construction of the structure is essentially wasted when the building is demolished. This includes the energy used in manufacturing construction materials, transporting them to the construction site, and assembling them into the building. Furthermore, the energy used in the demolition process itself, including the operation of heavy machinery, transportation of demolition waste, and disposal of materials, adds to the overall embodied energy consumption.
To address the environmental concerns associated with traditional demolition practices, sustainable alternatives are being explored and implemented in the construction and engineering industry. One such alternative is deconstruction, which involves carefully dismantling a structure to salvage and reuse as many materials as possible. This approach reduces the amount of waste generated and minimizes the need for new raw materials. Another sustainable practice is the use of advanced demolition techniques that prioritize the efficient use of energy and minimize environmental impact.
