Every year people consume mountains of papers all over the world. Producing a white, bright and clean paper is not as simple as it sounds. It is too costly and non-eco-friendly. To produce a high quality of white and bright printing and toilet paper, most paper mills use an excess amount of bleaching chemicals which are very expensive and harmful to the environment. During the initial stage of papermaking, wood chips are converted into the paper pulp through the chemical pulping process.
Several bleaching chemicals like chlorine dioxide, etc are used to bleach the dark brown wood pulp. And finally, it is processed into different products like printing and toilet paper. The paper mills were looking for eco-friendly cleaning alternatives. They ended their search with the discovery of biocatalyst in the form of industrial enzymes. These enzymes are proteins that offer a biological solution for paper production. They help the paper producers to cut down on the chemicals, improving the environment and saving a lot of their money.
Different Industrial Enzymes and Their Uses in the Paper Industry
These are Endo and Exo cellulase based enzymes. Deinking enzymes help to increase the brightness and to decrease the ink and dirt count in the pulp. Together with enhancing the ink particle removals, the use of these enzymes has also reduced the use of basic deinking chemicals in papermaking.
These biocatalyst products are based on Cellulase and Hemicellulase enzymes. It helps in increasing the fibrillation and improving drainage. It also reduces the amount of refining energy requirements for the pulping process.
Bleaching products are based on Xylanase enzyme and effectively used in the bleaching of craft, soda and sulfite pulp. It helps to enhance the lignin extraction due to losing fiber structure.
Starch Modification Enzymes
These are composed of Amylase enzyme and help in size press application by providing on-site modification of native starch. It allows the paper manufacturers a trouble-free control of starch viscosity and helps in substantial cost savings to the mill.
Pitch Control Enzyme
A Pitch management catalyst that controls pitch deposition on materials, press felts and machine surfaces. It helps scale back the additional cleansing and web breaks so saving pricy downtime in production.
The biocide product act against slime forming organisms and kills microorganism, yeast and mildew species. It’s compatible with ordinarily used wet finish additive and functions over a broad pH scale and temperature variations.
Pulp and Paper Mill Effluent Treatment
Best paper chemicals and producing agent suppliers offer an efficient mix of microorganisms, enzymes and organic compounds for Pulp and manufacturing plant Effluent Treatment. The product acts on paper effluents and effectively breaks down perishable chemicals, risky wastes, significant metals, and pathogens. This ends up in a forceful reduction of COD and BOD levels with enhancements in the odor and color of the effluent.
Enzymes are employed in heaps of various industries with advantages for producers and therefore the atmosphere. According to some online sources, in 2017, producers saved a calculable 76 million tons of CO2 emissions by applying Novozymes’ product. The savings achieved are like taking about 32 million cars off the road.
