Prefabrication as a mean of minimizing construction waste on site

What is it about?

Construction waste has become a major source of solid waste in Hong Kong. Thousands of tons of solid waste is produced every year from construction and demolition activities. Increasing generation of this waste has caused significant impacts on the environment and aroused public concerns. Therefore, minimization of construction waste has become a pressing issue. This paper aims to (i) reveal the status of construction waste, (ii) investigate the effectiveness of prefabrication in terms of waste reduction in replacing the traditional on-site production, (iii) examine the factors that help minimizing construction waste by the adopting prefabrication and (iv) explore the areas of waste reduction after adoption of prefabrication in comparison to traditional on-site production.
