Biological enzyme waste paper deinking agent

The State Key Laboratory of Microbial Technology of Shandong University cooperated with Shandong Zhucheng Papermaking Co., Ltd. to successfully produce de-inking agent for bio-enzymatic waste paper. The company conducted a production test at the company and produced a qualified 100% deinked pulp on a paper machine. Offset newsprint.


The key technology for producing this bio-enzyme deinking agent is to select excellent strains with short production cycle, high activity and large-scale production conditions. The process adopts solid fermentation technology with short process, low cost and high power. Tests have shown that deinking with biological enzymes is a neutral deinking process, which has the advantages of preventing paper yellowing, high oil black removal rate, good whiteness, good pulp water filtration, and reduced waste water pollution.
