Two students turned the glass a city threw away into new coastline
Thursday, September 17, 2026
New Orleans was burying its glass while its coast washed away. Two students, annoyed there was no recycling, decided the sand inside those bottles was worth saving.
Gather up the broken pieces which are left over, that nothing be lost.
John 6:12
Franziska Trautmann and Max Steitz were students at Tulane, frustrated that their city could barely recycle glass. New Orleans, ringed by disappearing coastline, sent its bottles from every bar and kitchen straight to the landfill. So in 2020 the two of them started crushing bottles by hand in a backyard.
Here is what made the waste sting. Glass is melted sand, and it can be recycled without end. Louisiana, meanwhile, has lost coastal land roughly the size of Delaware over the past century. The city was burying the exact material its shoreline was starving for.
Their nonprofit, Glass Half Full, grew from that backyard crusher into a plant of about three acres. By February 2026 it had kept more than 12 million pounds of glass out of the landfill. The crushed glass, ground back into sand, gets packed into biodegradable sacks and laid along eroding marsh. Native grasses root into it. The roots trap sediment. A shoreline starts to hold.
After feeding a hungry crowd from almost nothing, Jesus does something odd for a man who just made food appear. He tells the disciples to collect the leftover fragments so that nothing is lost. The same hands that multiplied the loaves reach down for the crumbs. Abundance, in his accounting, is no excuse for waste.
That instinct is what turned a startup into something closer to a repair. Material a whole city had written off as garbage became the one thing its coast could not do without.
Nothing good, it turns out, was ever meant to be thrown away.
