Kaisai Bio-Jinxiang stopped production. Kaisai is a scientific and technological enterprise, which mainly uses bio-manufacturing technology to produce new bio-based materials. Steam is an important energy source for Kasai bio-based production. In recent years, more and more enterprises have settled in Jining New Materials Industrial Park, where the company is located, and its scale has been expanding. The steam provided by the industrial park has been a bit backward, resulting in a certain degree of steam shortage, leading to production suspension.
