Enzymatic Deinking Technologies

Using Industrial Enzymes

Using Industrial Enzymes

Enzymes are easy to introduce into an industrial manufacturing setting such as pulp and paper processing. In many ways, they are the ideal raw material. They accelerate the desired chemical reactions efficiently and effectively within relatively narrow ranges of temperature and pH. 

Their application is straightforward, leveraging parts of the mill where a reasonable retention time with the stock is possible. Product applications occur with simple pumps. Enzymes break down quickly once removed from their required environment. In fact, even modest changes in pH and temperature can cause an enzyme to change its shape and permanently lose its activity. This process – called denaturing – changes an enzyme into inert proteins, joining the already large quantity of other proteins flowing through pulp and paper mill water systems.

What Do Enzymes Do For You?



Application Area




Household washing and cleaning agents

Wash your clothes in cold water; make your teeth cleaner



Denim washing, silk polishing, leather goods softening

Stonewash your jeans; make cotton look and feel like silk; make your leather soft


Food Processing

Baking, brewing, fruit juice processing

Clarify your juice and beer; make bread better; turn corn starch into sugar syrup


Pulp & Paper

Starch conversion, pitch control, bleach-boosting, deinking, stickies control, slime control

Reduce production costs and increase quality


Industrial enzymes are easily handled and stored. They have been used for decades in industries such as baking, brewing, food processing, textiles, detergents, and animal feed production. EDT’s enzyme products are liquids, carrying the following HMIS/FPIS Ratings: Health=1, Flammability=1, Reactivity=0.  They are among the safest materials in a mill. Prospective users can consult the Safety Data Sheet (SDS) for their product and contact EDT to discuss any questions.

Enzymes Are Safe

We eat enzymes – contained in most liquid food items purchased in stores (cheese, yogurt, juices, wine, beer)

We wear enzymes (detergents)

We are filled with enzymes (billions in our bodies)

Every mill is filled with enzymes… at all times

Enzymes have been safely applied in the P&P industry for decades
