Every year, 12 million tons of architectural glass from skyscrapers and office buildings ends up in landfills. Even though you diligently put your glass bottles in the recycling bin, only 30% of collected glass actually gets recycled back into glass.

Sydney Mainster, VP of Sustainability at The Durst Organization, is on a mission to change that. After watching hundreds of tons of perfectly recyclable glass from a 40-story building go to waste, she pioneered a partnership to recycle skyscraper windows across New York City.

In this episode, Sydney and David Entwistle (Director of Major Projects at Saint-Gobain Glass) reveal:

- Why glass is the ONLY material recyclers lose money on

- The hidden contamination problem that shuts down $40M furnaces

- How "sneaky sustainability" is making glass recycling standard practice

- Why interior office glass is the secret to scaling this solution

- The roadblocks preventing this from going national

Sydney and David are completely reimagining how we handle one of our most valuable building materials.
