On Earth Day, consider the potential--and the challenge--of recycling architectural glass
Yes. Glass can save the world, of course.
Glass stands as a cornerstone of contemporary design and building technology, contributing to both aesthetics and sustainability. Modern architectural glass supports sustainability goals by enhancing energy efficiency and offering versatile design possibilities. And, its recyclability further solidifies its role in environmentally conscious design.
However, despite its potential, recycling architectural glass faces these 4 significant challenges.
1. Complexity
Glass is often installed with non-glass components like framing and sealants, complicating the recycling process.
2. Sorting and purification
Contaminants present in the waste stream further hinder recycling efforts, calling for meticulous sorting and purification.
3. Transportation
The weight of glass and lack of a standardized collection infrastructure leads to inefficiencies and increased costs in handling and transporting glass waste. Specialized equipment and careful handling procedures are required, contributing to higher fuel consumption and emissions.
4. Lack of education
Inadequate awareness and education among stakeholders, coupled with the absence of clear regulatory frameworks, can also hamper progress in glass recycling. Without proper incentives and accountability measures, sustainable practices struggle to gain traction in the industry.
Addressing these challenges requires collaborative efforts and innovative solutions. Streamlining the recycling process, investing in infrastructure, and raising awareness about the environmental benefits of glass recycling are crucial steps toward a more sustainable future in architectural design and construction.
The NGA plays a vital role in supporting the industry’s awareness and advocacy efforts by authoring technical resources like our Flat Glass PCR, Flat Glass Global Warming Potential one-pager, and Recyclability of Architectural Glass technical paper, as well as our Sustainability and Recyclability task group that is working on a technical paper and a map of recyclers in the U.S. to aid in the logistics of recycling.
Additionally, NGA’s Glass and Glazing Advocacy Days event, held this year on May 14-15, allows members to engage with legislators on key issues like school security, workforce development, bird-friendly glazing, and high-performance glazing.
By facilitating dialogue between industry and legislators, we are taking active steps to overcome obstacles and promote sustainable practices in the architectural glass industry. Join us!
