Abstract

The construction industry results in a large amount of material waste, most of which currently ends up in landfills. This study aims to find new ways to reuse waste materials captured as outputs of construction projects. First, the circular economy (CE) concept is explored. Second, the application of CE as a potential solution for minimizing material waste on construction projects is investigated. To achieve a healthy industrial metabolism, the paper illustrates how a complex industrial ecosystem is one that produces little or no waste and whose constituents can be interdependent. Output ratios from the construction industry are compared with previous literature on material waste, as a foundation to present a cycle of material reuse. Reformulating the traditional input-output system into a more circular concept presents a set of challenges; however, the opportunities and significant impacts to the material cycles and landfills have proven beneficial and some major cities are starting to employ this concept with great success.
