Reusing and repurposing of glass waste: A literature review

Abstract

An increase in demolition activities has led to the generation of large amounts of glass waste. Due to its non-biodegradable nature, glass can stay in landfills for longer periods without decomposition; thus, it occupies a large volume of landfills. This study aimed to analyze the potential reuses and repurposing of glass waste in the construction industry. A systematic review of the literature was conducted, and secondary data were extracted. The data were analyzed qualitatively to achieve the objective of the study. The generation of glass waste in four different parts of the world, namely: Hong Kong, Australia, Europe and the USA has been studied to get an estimate for the increase in glass waste trends. The generation of glass waste saw a downfall from 2006 to 2010, was then steady from 2011 to 2016 and then slightly rose. A high volume of glass waste in landfills and its non-biodegradable nature has made it essential for the discovery of new methods of reuse and recycling of glass waste. Some of the potential reuse and repurposing options include Aggregate for Concrete, Filtration Media, Glass Fibres, Blast Abrasive, Roof Coating, Ceramic Based Products, Burnt Bricks, Low-Temperature Stoneware Tiles, Insulation, and Decorative Materials. The paper provides useful information to various stakeholders in the construction industry to understand how and where glass waste can be reused.
