Central Valley business converts almond shells into renewable resources

Turning what otherwise would be waste into renewable resources — and potentially money — is the promise of Mike Woelk, CEO of Merced-based company, Corigin. He says the process is known as pyrolysis, and it works by converting agricultural waste. Eight tons of almond shells each day are superheated to 475 degrees centigrade in a container without oxygen that preserves the chemical structures in the vapors that are then cooled into a liquid. This process creates two byproducts known as biochar and a distillate known as pyroligneous acid. See more above.
