Abstract

A recycling method for polyurethane waste includes mixing polyurethane waste with lactic acid to depolymerize the polyurethane waste, thereby obtaining a polyol recyclate that can be directly used to manufacture polyurethane. This invention primarily provides a method for directly converting polyurethane waste into reusable raw material using lactic acid as a depolymerizing agent.
