Can Pistachios Fuel a City?
All the power you need, in a nutshell. Turkey wants to use its huge pile of unused pistachio shells (it’s the world’s third-largest producer) as a power source. A new Turkish eco-city will ferment tons of pistachio shells in “digesters” and use the bio-gas to generate heat. The company that first suggested the idea estimates that the city — which will start construction in two years and will house 200,000 people — could generate 60 percent of its heat from the former waste product.
