Growstone recycles glass for greener growing

Post Time:Feb 08,2012Classify:Company NewsView:378

An Alburquerque company soon will operate 24/7 at the city's Cerro Colorado Landfill to grind and bake scrap glass into an agricultural product.


Growstone Inc. makes an environmentally friendly growing medium from glass that reportedly can aerate soil and improve production for hydroponic and commercial growers.


The company, which runs an 8,000-square-foot plant at the Westside landfill, just closed on a $3 million capital raise from private investors and the State Investment Council’s Co-Investment Fund to ramp up operations tenfold over the next six months, said Growstone CEO Mike Langone.


“We’ve increased our processing to about 30 tons per month now, but we plan to reach 300 tons per month, or about 3,600 tons annually, by June,” Langone said. “We’re getting out of startup mode and into full production.”


Growstone pays $20 per ton for the glass it receives from the city, which collects about 3,000 tons of scrap glass annually.
