Greensulate Developed by Rensselaer Grads


Rensselaer graduates (with dual degrees in mechanical engineering and PDI) Eben Bayer ’07 and Gavin McIntyre ’07 have developed an environmentally friendly organic insulation called Greensulate™. Created from waste agricultural materials, water, and mushrooms, the patent-pending insulation could replace conventional foam insulations, which are expensive to produce and harmful to the environment. The organic insulation is created by pouring a mixture of insulating particles, hydrogen peroxide, starch, and water into a panel enclosure, and injecting it with mushroom cells that digest the starch and produce a tightly meshed network of insulating particles and mycelium. The end result is an organic composite board that has a competitive R-Value—a measurement of resistance to heat flow — and can serve as a firewall. [via School of Engineering]
