The construction industry is the biggest industry in the world and flat glass is one of the crucial components of this sector that demands attention in terms of increased sustainability. The current processes of flat glass consumption and management are highly inefficient and unsustainable as most of the waste flat glass material gets dumped in landfills or is converted into glass wool. Such activities create a big carbon footprint and are a severe cause for concern. Research on flat glass emphasizes that it has a huge potential for an extended lifecycle. By employing sustainable consumption methods such as recycling and reuse, the greenhouse gas emissions and imminent energy losses in the flat glass ecosystem can be reduced significantly. Currently, there is a serious lack of sustainable systems and processes that use the hierarchy of waste management for flat glass. This study investigates consumer perceptions regarding recycling and reusing and identifies embedded enablers and barriers to discuss the possibilities available to improve the consumption mechanisms of flat glass consumption. Tested through the theoretical lens of obsolescence, the results show that psychological, technological, and economical barriers impede sustainable consumption of flat glass in the construction industry. There is a need for increased awareness among stakeholders, an enhanced customer-centricity, and increased stakeholder engagement to facilitate a change in mindset among the commercial consumers to support and promote the recycling and reuse of flat glass.
