Enzymes Reduce the Energy and Wood Fiber Required to Manufacture High Quality Paper and Paperboard
By: Brooke Winters, Kelly Li, Darius Reiter

2. The Importance of Paper and Paperboard
Paper industry employs 400,000 people
$115 billion in sales per year
Paper makes up a large percentage of waste produced each year
“Previously, papermakers who needed to improve paper strength were limited to adding costly pulps, increasing mechanical treatment that expends significant energy, or using various chemical additives”

3. What’s an Enzyme?
Definition: a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Enzymes are made up of proteins and are found everywhere in nature
Buckman’s Maximyze®
Combination of new cellulase enzymes and others produced from fermentation
Derived from renewable resources

4. Buckman’s Maximyze®
Maximyze® improves the paper production process by modifying “the cellulose in wood to increase the number of "fibrils" that bind the wood fibers to each other, thus making paper with improved strength and quality—without additional chemicals or energy” (EPA).
Put simply?
Increased efficiency, less energy

5. What Does Maximyze® Do?
The Maximyze enzymes change the cellulose in the wood fibers so that there is more surface area where hydrogen molecules bond. Since the fibers are not weakened and the structural integrity remains intact, while increasing strength and quality.

6. Maximyze
Non-Treated With Treatment

7. How is it Green? Made from a renewable resource Completely recyclable
Low toxicity
Principle 7 - A raw material or feedstock should be renewable rather than depleting,
wherever technically and economically practicable
Principle 3 - Wherever practicable, synthetic methodologies should be designed to
use and generate substances that possess little or no toxicity to human health and the environment

8. The Benefits Able to use higher percentage of recycled paper
Able to replace wood fiber mineral fillers (Ex. Calcium Carbonate)
Increased production speeds due to less steam and quicker draining of paper
Less toxic, safer to handle, manufacture, and Transport
A renewable resource
Completely recyclable
Reduces pulp required (Reduces trees required in production)
Reduces of weight of paper while maintaining quality

9. The commercial application
In 2011, a pulp and paper manufacturer in the Northwest began to add Maximyze enzymes to the bleached pulp used to produce paperboard for food containers.
Using Maximyze technology for this one machine can save wood pulp equivalent to 25,000 trees per year.
Another large mill producing fine paper has used Buckman’s technology since January 2010 and saved over $1 million per year.
Buckman has expanded it and is now applying it successfully in over 50 paper mills in the United States and beyond.
