Abstract
Disclosed are a method for producing lactic acid from wastes containing cellulose and/or hemicellulose and a catalyst for thermochemical conversion reaction of wastes containing cellulose and/or hemicellulose. The method includes a step of adding a metal catalyst to wastes containing cellulose and/or hemicellulose and performing thermochemical conversion reaction. The method provides an effect of producing lactic acid from discarded wastes, e.g., waste paper such as waste corrugated paperboards, waste paper boxes, waste newspapers, etc.
Claims6
